+### Added
+- Support for escrow (possible because of two other new things: cryptoconditions with inverters, and a timeout condition): [Pull Request #329](https://github.com/bigchaindb/bigchaindb/pull/329)
+- Caching of calls to `load_consensus_plugin()`, using [`@lru_cache`](https://docs.python.org/3/library/functools.html#functools.lru_cache). This speeds up the instantiation of `Bigchain` objects and greatly improves overall performance. [Pull Request #271](https://github.com/bigchaindb/bigchaindb/pull/271)
+- New `Dockerfile-dev` Docker file to make it easier for developers to _develop_ BigchainDB with Docker. One can run all unit tests with Docker again. [Pull Request #313](https://github.com/bigchaindb/bigchaindb/pull/313)
+- Transactions in invalid blocks are copied to the backlog: [Pull Request #221](https://github.com/bigchaindb/bigchaindb/pull/221).
+- Queries to the bigchain table now ignore invalid blocks: [Pull Request #324](https://github.com/bigchaindb/bigchaindb/issues/324)
+- Use secondary index on get_transaction: [Pull Request #324](https://github.com/bigchaindb/bigchaindb/issues/324)
+- New `bigchaindb` command to set the number of RethinkDB shards (in both tables): [Pull Request #258](https://github.com/bigchaindb/bigchaindb/pull/258)
+- Better handling of an outdated `setuptools`: [Pull Request #279](https://github.com/bigchaindb/bigchaindb/pull/279)
+
+### Changed
+- The block processes now use GroupProcess: [Pull Request #267](https://github.com/bigchaindb/bigchaindb/pull/267)
+- Replaced the `json` Python package with `rapidjson` (a Python wrapper for a fast JSON parser/generator written in C++), to speed up JSON serialization and deserialization: [Pull Request #318](https://github.com/bigchaindb/bigchaindb/pull/318)
+- Overhauled `ROADMAP.md` and moved it to [the bigchaindb/org repository](https://github.com/bigchaindb/org): Pull Requests 
+[#282](https://github.com/bigchaindb/bigchaindb/pull/282),
+[#306](https://github.com/bigchaindb/bigchaindb/pull/306),
+[#308](https://github.com/bigchaindb/bigchaindb/pull/308),
+[#325](https://github.com/bigchaindb/bigchaindb/pull/325)
+- AWS deployment has better support for [New Relic Server Monitoring](https://newrelic.com/server-monitoring): [Pull Request #316](https://github.com/bigchaindb/bigchaindb/pull/316)
+- AWS deployment script now reads from a configuration file: [Pull Request #291](https://github.com/bigchaindb/bigchaindb/pull/291)
+- AWS deployment script doesn't auto-start the BigchainDB servers anymore: [Pull Request #257](https://github.com/bigchaindb/bigchaindb/pull/257)
+
+### Fixed
+- Bug related to transaction malleability: [Pull Request #281](https://github.com/bigchaindb/bigchaindb/pull/281)
+
+### Notes
+You can now see a big-picture view of all BigchainDB repositories on [a waffle.io board](https://waffle.io/bigchaindb/org).
