+##   ACTION: [AUDIENCE:] COMMIT_MSG [!TAG ...]
+##
+## Description
+##
+##   ACTION is one of 'chg', 'fix', 'new'
+##
+##       Is WHAT the change is about.
+##
+##       'chg' is for refactor, small improvement, cosmetic changes...
+##       'fix' is for bug fixes
+##       'new' is for new features, big improvement
+##
+##   AUDIENCE is optional and one of 'dev', 'usr', 'pkg', 'test', 'doc'
+##
+##       Is WHO is concerned by the change.
+##
+##       'dev'  is for developpers (API changes, refactors...)
+##       'usr'  is for final users (UI changes)
+##       'pkg'  is for packagers   (packaging changes)
+##       'test' is for testers     (test only related changes)
+##       'doc'  is for doc guys    (doc only changes)
+##
+##   COMMIT_MSG is ... well ... the commit message itself.
+##
+##   TAGs are additionnal adjective as 'refactor' 'minor' 'cosmetic'
+##
+##       They are preceded with a '!' or a '@' (prefer the former, as the
+##       latter is wrongly interpreted in github.) Commonly used tags are:
+##
+##       'refactor' is obviously for refactoring code only
+##       'minor' is for a very meaningless change (a typo, adding a comment)
+##       'cosmetic' is for cosmetic driven change (re-indentation, 80-col...)
+##       'wip' is for partial functionality but complete subfunctionality.
+##
+## Example:
+##
+##   new: usr: support of bazaar implemented
+##   chg: re-indentend some lines !cosmetic
+##   new: dev: updated code to be compatible with last version of killer lib.
+##   fix: pkg: updated year of licence coverage.
+##   new: test: added a bunch of test around user usability of feature X.
+##   fix: typo in spelling my name in comment. !minor
+##
+##   Please note that multi-line commit message are supported, and only the
+##   first line will be considered as the "summary" of the commit message. So
+##   tags, and other rules only applies to the summary.  The body of the commit
+##   message will be displayed in the changelog without reformatting.

+##   - ReSub(pattern, replacement): will apply regexp substitution.
+##
+##   - Indent(chars="  "): will indent the text with the prefix
+##     Please remember that template engines gets also to modify the text and
+##     will usually indent themselves the text if needed.
+##
+##   - Wrap(regexp=r"\n\n"): re-wrap text in separate paragraph to fill 80-Columns
+##
+##   - noop: do nothing
+##
+##   - ucfirst: ensure the first letter is uppercase.
+##     (usually used in the ``subject_process`` pipeline)

+##   - final_dot: ensure text finishes with a dot
+##     (usually used in the ``subject_process`` pipeline)
+##
+##   - strip: remove any spaces before or after the content of the string
+##
+##   - SetIfEmpty(msg="No commit message."): will set the text to
+##     whatever given ``msg`` if the current text is empty.
+##
+## Additionally, you can `pipe` the provided filters, for instance:

+#body_process = noop

+##        This is the default.
+##
+##   - mustache(<template_name>)
+##
+##        Template name could be any of the available templates in
+##        ``templates/mustache/*.tpl``.
+##        Requires python package ``pystache``.
+##        Examples:
+##           - mustache("markdown")
+##           - mustache("restructuredtext")
+##
+##   - makotemplate(<template_name>)
+##
+##        Template name could be any of the available templates in

+##
+## This option tells git-log whether to include merge commits in the log.
+## The default is to include them.
+include_merge = True
+
+
+## ``log_encoding`` is a string identifier
+##
+## This option tells gitchangelog what encoding is outputed by ``git log``.
+## The default is to be clever about it: it checks ``git config`` for
+## ``i18n.logOutputEncoding``, and if not found will default to git's own
+## default: ``utf-8``.
+#log_encoding = 'utf-8'
+
+
+## ``publish`` is a callable
+##
+## Sets what ``gitchangelog`` should do with the output generated by
+## the output engine. ``publish`` is a callable taking one argument
+## that is an interator on lines from the output engine.
+##
+## Some helper callable are provided:
+##
+## Available choices are:
+##
+##   - stdout
+##
+##        Outputs directly to standard output
+##        (This is the default)
+##
+##   - FileInsertAtFirstRegexMatch(file, pattern, idx=lamda m: m.start())
+##
+##        Creates a callable that will parse given file for the given
+##        regex pattern and will insert the output in the file.
+##        ``idx`` is a callable that receive the matching object and
+##        must return a integer index point where to insert the
+##        the output in the file. Default is to return the position of
+##        the start of the matched string.
+##
+##   - FileRegexSubst(file, pattern, replace, flags)
+##
+##        Apply a replace inplace in the given file. Your regex pattern must
+##        take care of everything and might be more complex. Check the README
+##        for a complete copy-pastable example.
+##

+## ``revs`` is a list of callable or a list of string
+##
+## callable will be called to resolve as strings and allow dynamical
+## computation of these. The result will be used as revisions for
+## gitchangelog (as if directly stated on the command line). This allows
+## to filter exaclty which commits will be read by gitchangelog.
+##
+## To get a full documentation on the format of these strings, please
+## refer to the ``git rev-list`` arguments. There are many examples.
+##
+## Using callables is especially useful, for instance, if you
+## are using gitchangelog to generate incrementally your changelog.
+##
+## Some helpers are provided, you can use them::
+##
+##   - FileFirstRegexMatch(file, pattern): will return a callable that will
+##     return the first string match for the given pattern in the given file.
+##     If you use named sub-patterns in your regex pattern, it'll output only
+##     the string matching the regex pattern named "rev".
+##
+##   - Caret(rev): will return the rev prefixed by a "^", which is a
+##     way to remove the given revision and all its ancestor.
+##
+## Please note that if you provide a rev-list on the command line, it'll
+## replace this value (which will then be ignored).
+##
+## If empty, then ``gitchangelog`` will act as it had to generate a full
+## changelog.
+##
+## The default is to use all commits to make the changelog.

+Thanks for your contribution!
+
+* Make sure to clone the project with `git clone --recursive` so that
+  the submodules are initialized correctly.
+* To enable both tests and benchmarks, configure ryml with `-DRYML_DEV=ON`
+  when calling cmake. To enable only tests, use `-DRYML_BUILD_TESTS=ON`; to
+  enable only benchmarks use `-DRYML_BUILD_BENCHMARKS=ON`. All these flags
+  are disabled by default.
+* Code style for pull requests should respect the existing code style:
+    ```c++
+    if(foo)  // no space before parens
+    {   // curly brackets on next line
+        // no tabs; indent with 4 spaces
+        bar();
+    }

+# Roadmap
+
+Roughly in order of priority:
+
+  * Cleanup:
+    * Review & cleanup API surface.
+    * Turn calls to `C4_ASSERT()` into calls to `RYML_ASSERT()`
+  * Add emit formatting controls:
+    * add single-line flow formatter
+    * add multi-line flow formatters
+      * indenting
+      * non indenting
+    * keep current block formatter
+    * add customizable linebreak limits (number of columns) to every formatter
+    * add per node format flags
+    * (lesser priority) add auto formatter using reasonable heuristics to
+      switch between other existing formatters
+  * Investigate possibility of comment-preserving roundtrips

+This is the first ryml release. Future releases will have a more organized changelog; for now, only recent major changes are listed.
+
+Please be aware that there are still some anticipated breaking changes in the API before releasing the 1.0 major version. These are highlighted in [the repo ROADMAP](https://github.com/biojppm/rapidyaml/blob/v0.1.0/ROADMAP.md).
+
+* 2020/October
+  * [MR#89](https://github.com/biojppm/rapidyaml/pull/89):
+     * fix python API generation in windows
+     * use github actions for testing and releasing
+  * [MR#88](https://github.com/biojppm/rapidyaml/pull/88): [fix MacOS compilation and installs](https://github.com/biojppm/rapidyaml/issues/75). This is a fix from [c4core](https://github.com/biojppm/cmake/issues/1).
+  * [MR#88](https://github.com/biojppm/rapidyaml/pull/88): [fix boolean handling](https://github.com/biojppm/rapidyaml/issues/74). This is a fix from [c4core](https://github.com/biojppm/c4core/pull/18/).  `true` and  `false` are now parsed correctly into `bool` variables:
+    ```c++
+    auto tree = parse("{foo: true, bar: false}");
+    ```
+    Emitting `bool` variables still defaults to `0`/`1`, like the default behaviour in the STL. To explicitly request `true`/`false` use `c4::fmt::boolalpha()`:
+    ```c++
+    node << var;                     // "1"    or "0"
+    node << c4::fmt::boolalpha(var); // "true" or "false"
+    ```
+* 2020/September
+  * [***Breaking change***] [MR#85](https://github.com/biojppm/rapidyaml/pull/85) null values in YAML are now parsed to null strings instead of YAML null token "~":
+    ```c++
+    auto tree = parse("{foo: , bar: ''}");
+    // previous:
+    assert(tree["foo"].val() == "~");
+    assert(tree["bar"].val() == "");
+    // now:
+    assert(tree["foo"].val() == nullptr); // notice that this is now null
+    assert(tree["bar"].val() == "");
+    ```
+  * [MR#85](https://github.com/biojppm/rapidyaml/pull/85) Commas after tags are now allowed:
+    ```yaml
+    {foo: !!str, bar: ''}  # now the comma does not cause an error
+    ```
+  * [MR#81](https://github.com/biojppm/rapidyaml/pull/81): Always compile with extra pedantic warnings.
+* 2020/May
+  *  [***Breaking change***] the error callback now receives a source location object:
+    ```c++
+    // previous
+    using pfn_error = void (*)(const char* msg, size_t msg_len, void *user_data);
+    // now:
+    using pfn_error = void (*)(const char* msg, size_t msg_len, Location location, void *user_data);
+    ```
+  * Parser fixes to improve test suite success: [MR#73](https://github.com/biojppm/rapidyaml/pull/73), [MR#71](https://github.com/biojppm/rapidyaml/pull/71), [MR#68](https://github.com/biojppm/rapidyaml/pull/68), [MR#67](https://github.com/biojppm/rapidyaml/pull/67), [MR#66](https://github.com/biojppm/rapidyaml/pull/66)
+  * Fix compilation as DLL on windows [MR#69](https://github.com/biojppm/rapidyaml/pull/69)

+This release is focused on bug fixes and compliance with the [YAML test suite](https://github.com/yaml/yaml-test-suite).
+
+### Breaking changes
+
+- Fix parsing behavior of root-level scalars: now these are parsed into a DOCVAL, not SEQ->VAL ([5ba0d56](https://github.com/biojppm/rapidyaml/pull/144/commits/5ba0d56904daef1509f0073695145c4835ab1b30), from [PR #144](https://github.com/biojppm/rapidyaml/pull/144)). Eg,
+  ```yaml
+  ---
+  this is a scalar
+  --- # previously this was parsed as
+  - this is a scalar
+  ```
+- Cleanup type predicate API ([PR #155](https://github.com/biojppm/rapidyaml/pull/155))):
+  - ensure all type predicates from `Tree` and `NodeRef` forward to the corresponding predicate in `NodeType`
+  - remove all type predicates and methods from `NodeData`; use the equivalent call from `Tree` or `NodeRef`. For example, for `is_map()`:
+    ```c++
+    Tree t = parse("{foo: bar}");
+    size_t map_id = t.root_id();
+    NodeRef map = t.rootref();
+    t.get(map_id)->is_map(); // compile error: no longer exists
+    assert(t.is_map(map_id)); // OK
+    assert(map.is_map()); // OK
+    ```
+  - Further cleanup to the type predicate API will be done in the future, especially around the `.has_*()` vs corresponding `.is_*()` naming scheme.
+
+
+### New features & improvements
+
+- `Tree::lookup_path_or_modify()`: add overload to graft existing branches ([PR #141](https://github.com/biojppm/rapidyaml/pull/141))
+- Callbacks: improve test coverage ([PR #141](https://github.com/biojppm/rapidyaml/pull/141))
+- [YAML test suite](https://github.com/yaml/yaml-test-suite) ([PR #144](https://github.com/biojppm/rapidyaml/pull/144), [PR #145](https://github.com/biojppm/rapidyaml/pull/145)): big progress towards compliance with the suite. There are still a number of existing problems, which are the subject of ongoing work. See the [list of current known failures](../test/test_suite/test_suite_parts.cpp) in the test suite file.
+- Python wheels and source package are now [uploaded to PyPI](https://pypi.org/project/rapidyaml/) as part of the release process.
+
+
+### Fixes
+
+#### Anchors and references
+- Fix resolving of nodes with keyref+valref ([PR #144](https://github.com/biojppm/rapidyaml/pull/144)): `{&a a: &b b, *b: *a}`
+- Fix parsing of implicit scalars when tags are present ([PR #145](https://github.com/biojppm/rapidyaml/pull/145)):
+  ```yaml
+  - &a  # test case PW8X
+  - a
+  - &a : a
+    b: &b
+  - &c : &a
+  - ? &d
+  - ? &e
+    : &a
+  ```
+- Fix [#151](https://github.com/biojppm/rapidyaml/issues/151): scalars beginning with `*` or `&` or `<<` are now correctly quoted when emitting ([PR #156](https://github.com/biojppm/rapidyaml/pull/156)).
+- Also from [PR #156](https://github.com/biojppm/rapidyaml/pull/156), map inheritance nodes like `<<: *anchor` or `<<: [*anchor1, *anchor2]` now have a `KEYREF` flag in their type (until a call to `Tree::resolve()`):
+  ```c++
+  Tree tree = parse("{map: &anchor {foo: bar}, copy: {<<: *anchor}}");
+  assert(tree["copy"]["<<"].is_key_ref()); // previously this did not hold
+  assert(tree["copy"]["<<"].is_val_ref()); // ... but this did
+  ```
+
+#### Tags
+- Fix parsing of tag dense maps and seqs ([PR #144](https://github.com/biojppm/rapidyaml/pull/144)):
+  ```yaml
+  --- !!map {
+    k: !!seq [ a, !!str b],
+    j: !!seq
+       [ a, !!str b]
+  --- !!seq [
+    !!map { !!str k: v},
+    !!map { !!str ? k: v}
+  ]
+  --- !!map
+  !!str foo: !!map  # there was a parse error with the multiple tags
+    !!int 1: !!float 20.0
+    !!int 3: !!float 40.0
+  --- !!seq
+  - !!map
+    !!str k1: v1
+    !!str k2: v2
+    !!str k3: v3
+  ```
+
+#### Whitespace
+- Fix parsing of double-quoted scalars with tabs ([PR #145](https://github.com/biojppm/rapidyaml/pull/145)):
+  ```yaml
+  "This has a\ttab"
+  # is now correctly parsed as "This has a<TAB>tab"
+  ```
+- Fix filtering of leading and trailing whitespace within double-quoted scalars ([PR #145](https://github.com/biojppm/rapidyaml/pull/145)):
+  ```yaml
+  # test case 4ZYM, 7A4E, TL85
+  "
+  <SPC><SPC>foo<SPC>
+  <SPC> 
+  <SPC><TAB><SPC>bar
+  <SPC><SPC>baz
+  "
+  # is now correctly parsed as " foo\nbar\nbaz "
+  ```
+- Fix parsing of tabs within YAML tokens ([PR #145](https://github.com/biojppm/rapidyaml/pull/145)):
+  ```yaml
+  ---<TAB>scalar   # test case K54U
+  ---<TAB>{}       # test case Q5MG
+  ---              # test case DC7X
+  a: b<TAB>
+  seq:<TAB>
+   - a<TAB>
+  c: d<TAB>#X
+  ```
+- Fix parsing of flow-style maps with ommitted values without any space ([PR #145](https://github.com/biojppm/rapidyaml/pull/145)):
+  ```yaml
+  # test case 4ABK
+  - {foo: , bar: , baz: }  # this was parsed correctly as {foo: ~, bar: ~, baz: ~}
+  - {foo:, bar:, baz:}     # ... but this was parsed as {'foo:': , 'bar:': ~, 'baz:': ~}
+  ```
+
+#### Scalars
+- Unescape forward slashes in double quoted string ([PR #145](https://github.com/biojppm/rapidyaml/pull/145)):
+  ```yaml
+  --- escaped slash: "a\/b"   # test case 3UYS
+  # is now parsed as:
+  --- escaped slash: "a/b"
+  ```
+- Fix filtering of indented regions in folded scalars ([PR #145](https://github.com/biojppm/rapidyaml/pull/145)):
+  ```yaml
+  # test case 7T8X
+  - >
+    
+    folded
+    line
+    
+    next
+    line
+      * bullet
+    
+      * list
+      * lines
+    
+    last
+    line
+  ```
+  is now correctly parsed as `\nfolded line\nnext line\n  * bullet\n\n  * list\n  * lines\n\nlast line\n`.
+- Fix parsing of special characters within plain scalars ([PR #145](https://github.com/biojppm/rapidyaml/pull/145)):
+  ```yaml
+  # test case 3MYT
+  k:#foo
+    &a !t s
+    !t s
+  # now correctly parsed as "k:#foo &a !t s !t s"
+  ```
+- Fix parsing of comments after complex keys ([PR #145](https://github.com/biojppm/rapidyaml/pull/145)):
+  ```yaml
+  # test case X8DW
+  ? key
+  # comment 
+  : value
+  # now correctly parsed as {key: value}
+  ```
+- Fix parsing of consecutive complex keys within maps ([PR #145](https://github.com/biojppm/rapidyaml/pull/145))
+  ```yaml
+  # test case 7W2P, ZWK4
+  ? a
+  ? b
+  c:
+  ? d
+  e:
+  # now correctly parsed as {a: ~, b: ~, c: ~, d: ~, e: ~}
+  ```
+- Fix [#152](https://github.com/biojppm/rapidyaml/issues/152):  parse error with folded scalars that are the last in a container ([PR #157](https://github.com/biojppm/rapidyaml/pull/157)):
+  ```yaml
+  exec:
+    command:
+      # before the fix, this folded scalar failed to parse
+      - |
+        exec pg_isready -U "dog" -d "dbname=dog" -h 127.0.0.1 -p 5432
+    parses: no
+  ```
+- Fix: documents consisting of a quoted scalar now retain the VALQUO flag ([PR #156](https://github.com/biojppm/rapidyaml/pull/156))
+  ```c++
+  Tree tree = parse("'this is a quoted scalar'");
+  assert(tree.rootref().is_doc());
+  assert(tree.rootref().is_val());
+  assert(tree.rootref().is_val_quoted());
+  ```
+
+
+#### Document structure
+- Empty docs are now parsed as a docval with a null node:
+  ```yaml
+  ---   # test cases 6XDY, 6ZKB, 9BXL, PUW8
+  ---
+  ---
+  ```
+  is now parsed as
+  ```yaml
+  --- ~
+  --- ~
+  --- ~
+  ```
+- Prevent creation of DOC nodes from stream-level comments or tags ([PR #145](https://github.com/biojppm/rapidyaml/pull/145)):
+  ```yaml
+  !foo "bar"
+  ...
+  # Global
+  %TAG ! tag:example.com,2000:app/
+  ---
+  !foo "bar"
+  ```
+  was parsed as
+  ```yaml
+  ---
+  !foo "bar"
+  ---
+  # notice the empty doc in here
+  ---
+  !foo "bar"
+  ```
+  and it is now correctly parsed as
+  ```yaml
+  ---
+  !foo "bar"
+  ---
+  !foo "bar"
+  ```
+  (other than the known limitation that ryml does not do tag lookup).
+
+
+#### General
+
+- Fix [#147](https://github.com/biojppm/rapidyaml/issues/147): serialize/deserialize special float values `.nan`, `.inf`, `-.inf` ([PR #149](https://github.com/biojppm/rapidyaml/pull/149))
+- Fix [#142](https://github.com/biojppm/rapidyaml/issues/142): `preprocess_json()`: ensure quoted ranges are skipped when slurping containers
+- Ensure error macros expand to a single statement ([PR #141](https://github.com/biojppm/rapidyaml/pull/141))
+- Update c4core to [0.1.4](https://github.com/biojppm/c4core/releases/tag/v0.1.4)

+### Breaking changes
+
+Despite ryml being still in a non-stable 0.x.y version, considerable effort goes into trying to avoid breaking changes. However, this release has to collect on the [semantic versioning](https://semver.org/) prerogative for breaking changes. This is a needed improvement, so sorry for any nuisance!
+
+**The allocation and error callback logic was revamped** on the [amalgamation PR](https://github.com/biojppm/rapidyaml/pull/172). Now trees and parsers receive (and store) a full `ryml::Callbacks` object instead of the (now removed) `ryml::Allocator` which had a pointer to a (now removed) `ryml::MemoryResourceCallbacks`, which was a (now removed) `ryml::MemoryResource`. To be clear, the `Callbacks` class is unchanged, other than removing some unneeded helper methods.
+
+These changes were motivated by unfortunate name clashes between `c4::Allocator/ryml::Allocator` and `c4::MemoryResource/ryml::MemoryResource`, occurring if `<c4/allocator.hpp>` or `<c4/memory_resource.hpp>` were included before `<c4/yml/common.hpp>`. They also significantly simplify this part of the API, making it really easier to understand.
+
+As a consequence of the above changes, the global memory resource getters and setters for ryml were also removed: `ryml::get_memory_resource()/ryml::set_memory_resource()`.
+
+Here's an example of the required changes in client code. First the old client code (from the quickstart):
+
+```c++
+struct PerTreeMemoryExample : public ryml::MemoryResource
+{
+    void *allocate(size_t len, void * hint) override;
+    void free(void *mem, size_t len) override;
+};
+
+PerTreeMemoryExample mrp;
+PerTreeMemoryExample mr1;
+PerTreeMemoryExample mr2;
+
+ryml::Parser parser = {ryml::Allocator(&mrp)};
+ryml::Tree   tree1  = {ryml::Allocator(&mr1)};
+ryml::Tree   tree2  = {ryml::Allocator(&mr2)};
+```
+
+Should now be rewritten to:
+
+```c++
+struct PerTreeMemoryExample
+{
+    ryml::Callbacks callbacks() const; // helper to create the callbacks
+};
+
+PerTreeMemoryExample mrp;
+PerTreeMemoryExample mr1;
+PerTreeMemoryExample mr2;
+
+ryml::Parser parser = {mrp.callbacks()};
+ryml::Tree   tree1  = {mr1.callbacks()};
+ryml::Tree   tree2  = {mr2.callbacks()};

+
+### New features
+- Add amalgamation into a single header file ([PR #172](https://github.com/biojppm/rapidyaml/pull/172)):
+  - The amalgamated header will be available together with the deliverables from each release.
+  - To generate the amalgamated header:
+    ```console
+    $ python tools/amalgamate.py ryml_all.hpp
+    ```
+  - To use the amalgamated header:
+    - Include at will in any header of your project.
+    - In one - and only one - of your project source files, `#define RYML_SINGLE_HDR_DEFINE_NOW` and then `#include <ryml_all.hpp>`. This will enable the function and class definitions in the header file. For example, here's a sample program:
+      ```c++
+      #include <iostream>
+      #define RYML_SINGLE_HDR_DEFINE_NOW // do this before the include
+      #include <ryml_all.hpp>
+      int main()
+      {
+          auto tree = ryml::parse("{foo: bar}");
+          std::cout << tree["foo"].val() << "\n";
+      }
+      ```
+- Add `Tree::change_type()` and `NodeRef::change_type()` ([PR #171](https://github.com/biojppm/rapidyaml/pull/171)):
+  ```c++
+  // clears a node and sets its type to a different type (one of `VAL`, `SEQ`, `MAP`):
+  Tree t = parse("{keyval0: val0, keyval1: val1, keyval2: val2}");
+  t[0].change_type(VAL);
+  t[1].change_type(MAP);
+  t[2].change_type(SEQ);
+  Tree expected = parse("{keyval0: val0, keyval1: {}, keyval2: []}");
+  assert(emitrs<std::string>(t) == emitrs<std::string>(expected));
+  ```
+- Add support for compilation with emscripten (WebAssembly+javascript) ([PR #176](https://github.com/biojppm/rapidyaml/pull/176)).
+
+### Fixes
+
+- Take block literal indentation as relative to current indentation level, rather than as an absolute indentation level ([PR #178](https://github.com/biojppm/rapidyaml/pull/178)):
+  ```yaml
+  foo:
+    - |
+     child0
+    - |2
+      child2  # indentation is 4, not 2
+  ```
+- Fix parsing when seq member maps start without a key ([PR #178](https://github.com/biojppm/rapidyaml/pull/178)):
+  ```yaml
+  # previously this resulted in a parse error
+  - - : empty key
+  - - : another empty key
+  ```
+- Prefer passing `substr` and `csubstr` by value instead of const reference ([PR #171](https://github.com/biojppm/rapidyaml/pull/171))
+- Fix [#173](https://github.com/biojppm/rapidyaml/issues/173): add alias target `ryml::ryml` ([PR #174](https://github.com/biojppm/rapidyaml/pull/174))
+- Speedup compilation of tests by removing linking with yaml-cpp and libyaml. ([PR #177](https://github.com/biojppm/rapidyaml/pull/177))
+- Fix [c4core#53](https://github.com/biojppm/c4core/issues/53): cmake install targets were missing call to `export()` ([PR #179](https://github.com/biojppm/c4core/pull/179)).
+- Add missing export to `Tree` ([PR #181](https://github.com/biojppm/c4core/pull/181)).

+This release improves compliance with the [YAML test suite](https://github.com/yaml/yaml-test-suite/) (thanks @ingydotnet and @perlpunk for extensive and helpful cooperation), and adds node location tracking using the parser.
+
+
+### Breaking changes
+
+As part of the [new feature to track source locations](https://github.com/biojppm/rapidyaml/pull/168), opportunity was taken to address a number of pre-existing API issues. These changes consisted of:
+
+- Deprecate `c4::yml::parse()` and `c4::yml::Parser::parse()` overloads; all these functions will be removed in short order. Until removal, any call from client code will trigger a compiler warning.
+- Add `parse()` alternatives, either `parse_in_place()` or `parse_in_arena()`:
+  - `parse_in_place()` receives only `substr` buffers, ie mutable YAML source buffers. Trying to pass a `csubstr` buffer to `parse_in_place()` will cause a compile error:
+    ```c++
+    substr readwrite = /*...*/;
+    Tree tree = parse_in_place(readwrite); // OK
+    
+    csubstr readonly = /*...*/;
+    Tree tree = parse_in_place(readonly); // compile error
+    ```
+  - `parse_in_arena()` receives only `csubstr` buffers, ie immutable YAML source buffers. Prior to parsing, the buffer is copied to the tree's arena, then the copy is parsed in place. Because `parse_in_arena()` is meant for immutable buffers, overloads receiving a `substr` YAML buffer are now declared but marked deprecated, and intentionally left undefined, such that calling `parse_in_arena()` with a `substr` will cause a linker error as well as a compiler warning.
+    ```c++
+    substr readwrite = /*...*/;
+    Tree tree = parse_in_arena(readwrite); // compile warning+linker error
+    ```
+    This is to prevent an accidental extra copy of the mutable source buffer to the tree's arena: `substr` is implicitly convertible to `csubstr`. If you really intend to parse an originally mutable buffer in the tree's arena, convert it first explicitly to immutable by assigning the `substr` to a `csubstr` prior to calling `parse_in_arena()`:
+    ```c++
+    substr readwrite = /*...*/;
+    csubstr readonly = readwrite; // ok
+    Tree tree = parse_in_arena(readonly); // ok
+    ```
+    This problem does not occur with `parse_in_place()` because `csubstr` is not implicitly convertible to `substr`. 
+- In the python API, `ryml.parse()` was removed and not just deprecated; the `parse_in_arena()` and `parse_in_place()` now replace this.
+- `Callbacks`: changed behavior in `Parser` and `Tree`:
+  - When a tree is copy-constructed or move-constructed to another, the receiving tree will start with the callbacks of the original.
+  - When a tree is copy-assigned or move-assigned to another, the receiving tree will now change its callbacks to the original.
+  - When a parser creates a new tree, the tree will now use a copy of the parser's callbacks object.
+  - When an existing tree is given directly to the parser, both the tree and the parser now retain their own callback objects; any allocation or error during parsing will go through the respective callback object.
+
+
+### New features
+
+- Add tracking of source code locations. This is useful for reporting semantic errors after the parsing phase (ie where the YAML is syntatically valid and parsing is successful, but the tree contents are semantically invalid). The locations can be obtained lazily from the parser when the first location is queried:
+  ```c++
+  // To obtain locations, use of the parser is needed:
+  ryml::Parser parser;
+  ryml::Tree tree = parser.parse_in_arena("source.yml", R"({
+  aa: contents,
+  foo: [one, [two, three]]
+  })");
+  // After parsing, on the first call to obtain a location,
+  // the parser will cache a lookup structure to accelerate
+  // tracking the location of a node, with complexity
+  // O(numchars(srcbuffer)). Then it will do the lookup, with
+  // complexity O(log(numlines(srcbuffer))).
+  ryml::Location loc = parser.location(tree.rootref());
+  assert(parser.location_contents(loc).begins_with("{"));
+  // note the location members are zero-based:
+  assert(loc.offset == 0u);
+  assert(loc.line == 0u);
+  assert(loc.col == 0u);
+  // On the next call to location(), the accelerator is reused
+  // and only the lookup is done.
+  loc = parser.location(tree["aa"]);
+  assert(parser.location_contents(loc).begins_with("aa"));
+  assert(loc.offset == 2u);
+  assert(loc.line == 1u);
+  assert(loc.col == 0u);
+  // KEYSEQ in flow style: points at the key
+  loc = parser.location(tree["foo"]);
+  assert(parser.location_contents(loc).begins_with("foo"));
+  assert(loc.offset == 16u);
+  assert(loc.line == 2u);
+  assert(loc.col == 0u);
+  loc = parser.location(tree["foo"][0]);
+  assert(parser.location_contents(loc).begins_with("one"));
+  assert(loc.line == 2u);
+  assert(loc.col == 6u);
+  // SEQ in flow style: location points at the opening '[' (there's no key)
+  loc = parser.location(tree["foo"][1]);
+  assert(parser.location_contents(loc).begins_with("["));
+  assert(loc.line == 2u);
+  assert(loc.col == 11u);
+  loc = parser.location(tree["foo"][1][0]);
+  assert(parser.location_contents(loc).begins_with("two"));
+  assert(loc.line == 2u);
+  assert(loc.col == 12u);
+  loc = parser.location(tree["foo"][1][1]);
+  assert(parser.location_contents(loc).begins_with("three"));
+  assert(loc.line == 2u);
+  assert(loc.col == 17u);
+  // NOTE: reusing the parser with a new YAML source buffer
+  // will invalidate the accelerator.
+  ```
+  See more details in the [quickstart sample](https://github.com/biojppm/rapidyaml/blob/bfb073265abf8c58bbeeeed7fb43270e9205c71c/samples/quickstart.cpp#L3759). Thanks to @cschreib for submitting a working example proving how simple it could be to achieve this.
+- `Parser`:
+  - add `source()` and `filename()` to get the latest buffer and filename to be parsed
+  - add `callbacks()` to get the parser's callbacks
+- Add `from_tag_long()` and `normalize_tag_long()`:
+  ```c++
+  assert(from_tag_long(TAG_MAP) == "<tag:yaml.org,2002:map>");
+  assert(normalize_tag_long("!!map") == "<tag:yaml.org,2002:map>");
+  ```
+- Add an experimental API to resolve tags based on the tree's tag directives. This API is still imature and will likely be subject to changes, so we won't document it yet.
+- Regarding emit styles (see issue [#37](https://github.com/biojppm/rapidyaml/issues/37)): add an experimental API to force flow/block style on container nodes, as well as block-literal/block-folded/double-quoted/single-quoted/plain styles on scalar nodes. This API is also immature and will likely be subject to changes, so we won't document it yet. But if you are desperate for this functionality, the new facilities will let you go further.
+- Add preliminary support for bare-metal ARM architectures, with CI tests pending implementation of QEMU action. ([#193](https://github.com/biojppm/rapidyaml/issues/193), [c4core#63](https://github.com/biojppm/c4core/issues/63)).
+- Add preliminary support for RISC-V architectures, with CI tests pending availability of RISC-V based github actions. ([c4core#69](https://github.com/biojppm/c4core/pulls/69)).
+
+
+### Fixes
+
+- Fix edge cases of parsing of explicit keys (ie keys after `?`) ([PR#212](https://github.com/biojppm/rapidyaml/pulls/212)):
+  ```yaml
+  # all these were fixed:
+  ? : # empty
+  ? explicit key   # this comment was not parsed correctly
+  ?    # trailing empty key was not added to the map
+  ```
+- Fixed parsing of tabs used as whitespace tokens after `:` or `-`. This feature [is costly (see some benchmark results here)](https://github.com/biojppm/rapidyaml/pull/211#issuecomment-1030688035) and thus it is disabled by default, and requires defining a macro or cmake option `RYML_WITH_TAB_TOKENS` to enable ([PR#211](https://github.com/biojppm/rapidyaml/pulls/211)).
+- Allow tab indentation in flow seqs ([PR#215](https://github.com/biojppm/rapidyaml/pulls/215)) (6CA3).
+- ryml now parses successfully compact JSON code `{"like":"this"}` without any need for preprocessing. This code was not valid YAML 1.1, but was made valid in YAML 1.2. So the `preprocess_json()` functions, used to insert spaces after `:` are no longer necessary and have been removed. If you were using these functions, remove the calls and just pass the original source directly to ryml's parser ([PR#210](https://github.com/biojppm/rapidyaml/pulls/210)).
+- Fix handling of indentation when parsing block scalars ([PR#210](https://github.com/biojppm/rapidyaml/pulls/210)):
+  ```yaml
+  ---
+  |
+  hello
+  there
+  ---
+  |
+  ciao
+  qua
+  ---
+  - |
+   hello
+   there
+  - |
+   ciao
+   qua
+  ---
+  foo: |
+   hello
+   there
+  bar: |
+   ciao
+   qua
+  ```
+- Fix parsing of maps when opening a scope with whitespace before the colon ([PR#210](https://github.com/biojppm/rapidyaml/pulls/210)):
+  ```yaml
+  foo0 : bar
+  ---
+  foo1 : bar  # the " :" was causing an assert
+  ---
+  foo2 : bar
+  ---
+  foo3	: bar
+  ---
+  foo4   	  : bar
+  ```
+- Ensure container keys preserve quote flags when the key is quoted ([PR#210](https://github.com/biojppm/rapidyaml/pulls/210)).
+- Ensure scalars beginning with `%` are emitted with quotes (([PR#216](https://github.com/biojppm/rapidyaml/pulls/216)).
+- Fix [#203](https://github.com/biojppm/rapidyaml/issues/203): when parsing, do not convert `null` or `~` to null scalar strings. Now the scalar strings contain the verbatim contents of the original scalar; to query whether a scalar value is null, use `Tree::key_is_null()/val_is_null()` and `NodeRef::key_is_null()/val_is_null()` which return true if it is empty or any of the unquoted strings `~`, `null`, `Null`, or `NULL`. ([PR#207](https://github.com/biojppm/rapidyaml/pulls/207)):
+- Fix [#205](https://github.com/biojppm/rapidyaml/issues/205): fix parsing of escaped characters in double-quoted strings: `"\\\"\n\r\t\<TAB>\/\<SPC>\0\b\f\a\v\e\_\N\L\P"` ([PR#207](https://github.com/biojppm/rapidyaml/pulls/207)).
+- Fix [#204](https://github.com/biojppm/rapidyaml/issues/204): add decoding of unicode codepoints `\x` `\u` `\U` in double-quoted scalars:
+  ```c++
+  Tree tree = parse_in_arena(R"(["\u263A \xE2\x98\xBA \u2705 \U0001D11E"])");
+  assert(tree[0].val() == "☺ ☺ ✅ 𝄞");
+  ```
+  This is mandated by the YAML standard and was missing from ryml ([PR#207](https://github.com/biojppm/rapidyaml/pulls/207)).
+- Fix emission of nested nodes which are sequences: when these are given as the emit root, the `- ` from the parent node was added ([PR#210](https://github.com/biojppm/rapidyaml/pulls/210)):
+  ```c++
+  const ryml::Tree tree = ryml::parse_in_arena(R"(
+  - - Rochefort 10
+    - Busch
+    - Leffe Rituel
+    - - and so
+      - many other
+      - wonderful beers
+  )");
+  // before (error), YAML valid but not expected
+  //assert(ryml::emitrs<std::string>(tree[0][3]) == R"(- - and so
+  //  - many other
+  //  - wonderful beers
+  //)");
+  // now: YAML valid and expected
+  assert(ryml::emitrs<std::string>(tree[0][3]) == R"(- and so
+  - many other
+  - wonderful beers
+  )");
+  ```
+- Fix parsing of isolated `!`: should be an empty val tagged with `!` (UKK06-02) ([PR#215](https://github.com/biojppm/rapidyaml/pulls/215)).
+- Fix [#193](https://github.com/biojppm/rapidyaml/issues/193): amalgamated header missing `#include <stdarg.h>` which prevented compilation in bare-metal `arm-none-eabi` ([PR #195](https://github.com/biojppm/rapidyaml/pull/195), requiring also [c4core #64](https://github.com/biojppm/c4core/pull/64)).
+- Accept `infinity`,`inf` and `nan` as special float values (but not mixed case: eg `InFiNiTy` or `Inf` or `NaN` are not accepted) ([PR #186](https://github.com/biojppm/rapidyaml/pull/186)).
+- Accept special float values with upper or mixed case: `.Inf`, `.INF`, `.NaN`, `.NAN`. Previously, only low-case `.inf` and `.nan` were accepted ([PR #186](https://github.com/biojppm/rapidyaml/pull/186)).
+- Accept `null` with upper or mixed case: `Null` or `NULL`. Previously, only low-case `null` was accepted ([PR #186](https://github.com/biojppm/rapidyaml/pull/186)).
+- Fix [#182](https://github.com/biojppm/rapidyaml/issues/182): add missing export of DLL symbols, and document requirements for compiling shared library from the amalgamated header. [PR #183](https://github.com/biojppm/rapidyaml/pull/183), also [PR c4core#56](https://github.com/biojppm/c4core/pull/56) and [PR c4core#57](https://github.com/biojppm/c4core/pull/57).
+- Fix [#185](https://github.com/biojppm/rapidyaml/issues/185): compilation failures in earlier Xcode versions ([PR #187](https://github.com/biojppm/rapidyaml/pull/187) and [PR c4core#61](https://github.com/biojppm/c4core/pull/61)):
+  - `c4/substr_fwd.hpp`: (failure in Xcode 12 and earlier) forward declaration for `std::allocator` is inside the `inline namespace __1`, unlike later versions.
+  - `c4/error.hpp`: (failure in debug mode in Xcode 11 and earlier) `__clang_major__` does not mean the same as in the common clang, and as a result the warning `-Wgnu-inline-cpp-without-extern` does not exist there.
+- Ensure error messages do not wrap around the buffer when the YAML source line is too long ([PR#210](https://github.com/biojppm/rapidyaml/pulls/210)).
+- Ensure error is emitted on unclosed flow sequence characters eg `[[[` ([PR#210](https://github.com/biojppm/rapidyaml/pulls/210)). Same thing for `[]]`.
+- Refactor error message building and parser debug logging to use the new dump facilities in c4core ([PR#212](https://github.com/biojppm/rapidyaml/pulls/212)).
+- Parse: fix read-after-free when duplicating a parser state node, when pushing to the stack requires a stack buffer resize ([PR#210](https://github.com/biojppm/rapidyaml/pulls/210)).
+- Add support for legacy gcc 4.8 ([PR#217](https://github.com/biojppm/rapidyaml/pulls/217)).
+
+
+### Improvements
+
+- Rewrite filtering of scalars to improve parsing performance ([PR #188](https://github.com/biojppm/rapidyaml/pull/188)). Previously the scalar strings were filtered in place, which resulted in quadratic complexity in terms of scalar length. This did not matter for small scalars fitting the cache (which is the more frequent case), but grew in cost as the scalars grew larger. To achieve linearity, the code was changed so that the strings are now filtered to a temporary scratch space in the parser, and copied back to the output buffer after filtering, if any change occurred. The improvements were large for the folded scalars; the table below shows the benchmark results of throughput (MB/s) for several files containing large scalars of a single type:
+  | scalar type	| before |	after |	improvement |
+  |:------------|-------:|-------:|---------:|
+  | block folded   | 276	| 561	| 103% |
+  | block literal  | 331	| 611	| 85% |
+  | single quoted  | 247	| 267	| 8% |
+  | double quoted  | 212	| 230	| 8% |
+  | plain (unquoted) | 173	| 186	| 8% |
+  
+  The cost for small scalars is negligible, with benchmark improvement in the interval of -2% to 5%, so well within the margin of benchmark variability in a regular OS. In the future, this will be optimized again by copying each character in place, thus completely avoiding the staging arena.
+- `Callbacks`: add `operator==()` and `operator!=()` ([PR #168](https://github.com/biojppm/rapidyaml/pull/168)).
+- `Tree`: on error or assert prefer the error callback stored into the tree's current `Callbacks`, rather than the global `Callbacks` ([PR #168](https://github.com/biojppm/rapidyaml/pull/168)).
+- `detail::stack<>`: improve behavior when assigning from objects `Callbacks`, test all rule-of-5 scenarios ([PR #168](https://github.com/biojppm/rapidyaml/pull/168)).
+- Improve formatting of error messages.

+
+
+c4core is a library of low-level C++ utilities, written with low-latency
+projects in mind.
+
+Some of the utilities provided by c4core have already equivalent
+functionality in the C++ standard, but they are provided as the existing C++
+equivalent may be insufficient (eg, std::string_view), inefficient (eg,
+std::string), heavy (eg streams), or plainly unusable on some
+platforms/projects, (eg exceptions); some other utilities have equivalent
+under consideration for C++ standardisation; and yet some other utilities
+have (to my knowledge) no equivalent under consideration. Be that as it may,
+I've been using these utilities in this or similar forms for some years now,
+and I've found them incredibly useful in my projects. I'm packing these as a
+separate library, as all of my projects use it.
+
+c4core is [extensively unit-tested in Linux, Windows and
+MacOS](https://github.com/biojppm/c4core/actions). The tests cover
+x64, x86, arm, wasm (emscripten), aarch64, ppc64le and s390x
+architectures, and include analysing c4core with:
+  * valgrind
+  * clang-tidy
+  * clang sanitizers:
+    * memory
+    * address
+    * undefined behavior
+    * thread
+  * [LGTM.com](https://lgtm.com/projects/g/biojppm/c4core)
+
+c4core also works [in
+bare-metal](https://github.com/biojppm/c4core/issues/63) as well as
+[in RISC-V](https://github.com/biojppm/c4core/pull/69) but at the
+moment it's not easy to add automated tests to the CI, so for now
+these are not in the list of official architectures.
+
+
+## Obtaining c4core
+
+c4core uses git submodules. It is best to clone c4core with the `--recursive`
+option:
+
+```bash
+# using --recursive makes sure git submodules are also cloned at the same time
+git clone --recursive https://github.com/biojppm/c4core
+```
+
+If you ommit the `--recursive` option, then after cloning you will have to
+make git checkout the current version of the submodules, using `git submodule
+init` followed by `git submodule update`.
+
+
+## Using c4core in your project
+
+c4core is built with cmake, and assumes you also use cmake. Although c4core
+is NOT header-only, and currently has no install target, you can very easily
+use c4core in your project by using
+`add_subdirectory(${path_to_c4core_root})` in your CMakeLists.txt; this will
+add c4core as a subproject of your project. Doing this is not intrusive to
+your cmake project because c4core is fast to build (typically under 10s), and
+it also prefixes every cmake variable with `C4CORE_`. But more importantly
+this will enable you to compile c4core with the exact same compile settings
+used by your project.
+
+Here's a very quick complete example of setting up your project to use
+c4core:
+
+```cmake
+project(foo)
+
+add_subdirectory(c4core)
+
+add_library(foo foo.cpp)
+target_link_libraries(foo PUBLIC c4core) # that's it!
+```
+
+Note above that the call to `target_link_libraries()` is using PUBLIC
+linking. This is required to make sure the include directories from `c4core`
+are transitively used.
+
+
+## Quick tour
+
+All of the utilities in this library are under the namespace `c4`; any
+exposed macros use the prefix `C4_`: eg `C4_ASSERT()`.

+
+## New features
+
+These changes will provide new features, and client code can be kept
+unchanged.
+
+
+## API changes
+
+These changes will require client code to be updated.
+
+* [breaking] drop use of C-style sprintf() formats in error messages and
+  assertions. Change the implementation to use c4::format()
+  ```c++
+  C4_ASSERT_MSG(sz > s.size(), "sz=%zu s.size()=%zu", sz, s.size());

+
+## Implementation changes
+
+* drop calls to sprintf() in charconv.hpp.

+### New features
+
+- Add amalgamation into a single header file ([PR #48](https://github.com/biojppm/c4core/pull/48)):
+  - The amalgamated header will be available together with the deliverables from each release.
+  - To generate the amalgamated header:
+    ```
+    $ python tools/amalgamate.py c4core_all.hpp
+    ```
+  - To use the amalgamated header:
+    - Include at will in any header of your project.
+    - In one - and only one - of your project source files, `#define C4CORE_SINGLE_HDR_DEFINE_NOW` and then `#include <c4core_all.hpp>`. This will enable the function and class definitions in the header file. For example, here's a sample program:
+      ```c++
+      #include <iostream>
+      #define C4CORE_SINGLE_HDR_DEFINE_NOW // do this before the include
+      #include <c4core_all.hpp>
+      int main()
+      {
+          for(c4::csubstr s : c4::csubstr("a/b/c/d").split('/'))
+              std::cout << s << "\n";
+      }
+      ```
+- Add `csubstr::is_unsigned_integer()` and `csubstr::is_real()` ([PR #49](https://github.com/biojppm/c4core/pull/49)).
+- CMake: add alias target c4core::c4core, guaranteeing that the same code can be used with `add_subdirectory()` and `find_package()`. (see [rapidyaml #173](https://github.com/biojppm/rapidyaml/issues/173))
+- Add support for compilation with emscripten (WebAssembly+javascript) ([PR #52](https://github.com/biojppm/c4core/pull/52)).
+
+
+### Fixes
+
+- Fix edge cases with empty strings in `span::first()`, `span::last()` and `span::range()`  ([PR #49](https://github.com/biojppm/c4core/pull/49)).
+- Accept octal numbers in `substr::first_real_span()` and `substr::is_real()` ([PR #49](https://github.com/biojppm/c4core/pull/49)).
+- `substr`: fix coverage misses in number query methods ([PR #49](https://github.com/biojppm/c4core/pull/49)).
+- Use single-header version of fast_float ([PR #49](https://github.com/biojppm/c4core/pull/47)).
+- Suppress warnings triggered from fast_float in clang (`-Wfortify-source`) ([PR #49](https://github.com/biojppm/c4core/pull/47)).
+- Add missing `inline` in [src/c4/ext/rng/rng.hpp](src/c4/ext/rng/rng.hpp) ([PR #49](https://github.com/biojppm/c4core/pull/47)).
+- Fix compilation of [src/c4/ext/rng/inplace_function.h](src/c4/ext/inplace_function.h) in C++11 ([PR #49](https://github.com/biojppm/c4core/pull/47)).
+- Change order of headers, notably in `windows_push.hpp` ([PR #47](https://github.com/biojppm/c4core/pull/47)).
+- In `c4/charconv.hpp`: do not use C4_ASSERT in `to_c_fmt()`, which is `constexpr`.
+- Fix [#53](https://github.com/biojppm/c4core/issues/53): cmake install targets were missing call to `export()` ([PR #55](https://github.com/biojppm/c4core/pull/55)).
+- Fix linking of subprojects with libc++: flags should be forwarded through `CMAKE_***_FLAGS` instead of being set explicitly per-target ([PR #54](https://github.com/biojppm/c4core/pull/54)).

+### Breaking changes
+
+- fix [#63](https://github.com/biojppm/c4core/issues/63): remove `c4/time.hpp` and `c4/time.cpp` which prevented compilation in bare-metal mode ([PR #64](https://github.com/biojppm/c4core/issues/64)).
+
+### New features
+
+- Added decoding of UTF codepoints: `c4::decode_code_point()` ([PR #65](https://github.com/biojppm/c4core/issues/65)).
+- Experimental feature: add formatted-dumping facilities: using semantics like `c4::cat()`, `c4::catsep()` and `c4::format()`, where the subject is not a string buffer but a dump callback accepting strings. This still requires a string buffer for serialization of non-string types, but the buffer's required size is now limited to the max serialized size of non-string arguments, in contrast to the requirement in `c4::cat()` et al which is the total serialized size of every argument. This enables very efficient and generic printf-like semantics with reuse of a single small buffer, and allows direct-printing to terminal or file ([PR #67](https://github.com/biojppm/c4core/issues/67)). This feature is still experimental and a minor amount of changes to the API is possible.
+- Added macro `C4_IF_CONSTEXPR` resolving to `if constexpr (...)` if the c++ standard is at least c++17.
+- `csubstr`: add `count(csubstr)` overload.
+- Add support for RISC-V architectures ([PR #69](https://github.com/biojppm/c4core/issues/69)).
+- Add support for bare-metal compilation ([PR #64](https://github.com/biojppm/c4core/issues/64)).
+- gcc >= 4.8 support using polyfills for missing templates and features ([PR #74](https://github.com/biojppm/c4core/pull/74) and [PR #68](https://github.com/biojppm/c4core/pull/68)).
+
+### Fixes
+
+- `csubstr::operator==(std::nullptr_t)` now returns true if either `.str==nullptr` or `.len==0`.
+- Fix: `bool operator==(const char (&s)[N], csubstr)`  and `operator==(const char (&s)[N], substr)`. The template declaration for these functions had an extra `const` which prevented these functions to participate in overload resolution, which in some cases resulted in calls resolving to `operator==(std::string const&, csubstr)` if that header was visible ([PR #64](https://github.com/biojppm/c4core/issues/64)).
+- Fix `csubstr::last_not_of()`: optional positional parameter was ignored [PR #62](https://github.com/biojppm/c4core/pull/62).
+- `atof()`, `atod()`, `atox()`, `substr::is_real()`, `substr::first_real_span()`: accept `infinity`, `inf` and `nan` as valid reals [PR #60](https://github.com/biojppm/c4core/pull/60).
+- Add missing export symbols [PR #56](https://github.com/biojppm/c4core/pull/56), [PR #57](https://github.com/biojppm/c4core/pull/57).
+- `c4/substr_fwd.hpp`: fix compilation failure in Xcode 12 and earlier, where the forward declaration for `std::allocator` is inside the `inline namespace __1`, unlike later versions [PR #61](https://github.com/biojppm/c4core/pull/61), reported in [rapidyaml#185](https://github.com/biojppm/rapidyaml/issues/185).
+- `c4/error.hpp`: fix compilation failure in debug mode in Xcode 12 and earlier: `__clang_major__` does not mean the same as in the common clang, and as a result the warning `-Wgnu-inline-cpp-without-extern` does not exist there.

+#       [NO_DEFAULTS]
+#       [VARS var1 var2 ...]
+#       [EXCLUDE xvar1 xvar2 ...]
+#       [QUIET]
+#   )
+#
+# Get the current cmake environment in a sequence of -DVAR=${VAR}
+# tokens so that the environment can be forwarded to an external
+# cmake project through CMAKE_ARGS.
+#
+# Example:
+#   ExternalProject_GetFwdArgs(FWD_ARGS)
+#   ExternalProject_Add(foo SOURCE_DIR ../foo
+#       CMAKE_ARGS ${FWD_ARGS}
+#       ... etc)
+#
+# Use this function to enable forwarding the current cmake environment
+# to an external project. It outputs all the needed variables in the
+# form of a sequence of -DVAR=value, suitable for use in the CMAKE_ARGS
+# clause of ExternalProject_Add().
+#
+# This function uses ExternalProject_GetFwdVarNames() to find out the
+# list of variables to export. If this behaviour does not fit your
+# needs you can:
+#
+#     * append more of your own variables (using the VARS
+#       argument). The vars specified in this option will each be
+#       added to the output in the form of -Dvar=${var}
+#
+#     * you can also avoid any defaults obtained through usage of
+#       ExternalProject_GetFwdNames() by specifying NO_DEFAULTS.
+#
+# Example with custom variable names (adding more):
+#   ExternalProject_GetFwdVarNames(FWD_ARGS VARS USER_VAR1 USER_VAR2)
+#   ExternalProjectAdd(foo SOURCE_DIR ../foo CMAKE_ARGS ${FWD_ARGS})
+#
+# Example with custom variable names (just your own):
