## [1.0.0rc1] - 2017-06-??
Tag name: v1.0.0rc1
### Added
* Support for SSL/TLS auth and communications between MongoDB and BigchainDB, MongoDB Backup Agent, MongoDB Monitoring Agent, and MongoDB Cloud Manager. Pull Requests
[#1456](https://github.com/bigchaindb/bigchaindb/pull/1456),
[#1497](https://github.com/bigchaindb/bigchaindb/pull/1497),
[#1510](https://github.com/bigchaindb/bigchaindb/pull/1510),
[#1536](https://github.com/bigchaindb/bigchaindb/pull/1536), and
[#1551](https://github.com/bigchaindb/bigchaindb/pull/1551).
* Text search support (only if using MongoDB). Pull Requests [#1469](https://github.com/bigchaindb/bigchaindb/pull/1469) and [#1471](https://github.com/bigchaindb/bigchaindb/pull/1471)
* The `database.connection_timeout` configuration setting now works with RethinkDB too. [#1512](https://github.com/bigchaindb/bigchaindb/pull/1512)
* New code and tools for benchmarking CREATE transactions. [Pull Request #1511](https://github.com/bigchaindb/bigchaindb/pull/1511)
### Changed
* There's an upgrade guide in `docs/upgrade-guides/v0.10-->v1.0.md`. It only covers changes to the transaction model and HTTP API. If that file hasn't been merged yet, see [Pull Request #1547](https://github.com/bigchaindb/bigchaindb/pull/1547)
* Cryptographic signatures now sign the whole (serialized) transaction body, including the transaction ID, but with all `"fulfillment"` values changed to `None`. [Pull Request #1225](https://github.com/bigchaindb/bigchaindb/pull/1225)
* In transactions, the value of `"amount"` must be a string. (Before, it was supposed to be a number.) [Pull Request #1286](https://github.com/bigchaindb/bigchaindb/pull/1286)
* In `setup.py`, the "Development Status" (as reported on PyPI) was changed from Alpha to Beta. [Pull Request #1437](https://github.com/bigchaindb/bigchaindb/pull/1437)
* If you explicitly specify a config file, e.g. `bigchaindb -c path/to/config start` and that file can't be found, then BigchainDB Server will fail with a helpful error message. [Pull Request #1486](https://github.com/bigchaindb/bigchaindb/pull/1486)
* Reduced the response time on the HTTP API endpoint to get all the unspent outputs associated with a given public key (a.k.a. "fast unspents"). [Pull Request #1411](https://github.com/bigchaindb/bigchaindb/pull/1411)
* Internally, the value of an asset's `"data"` is now stored in a separate assets table. This enabled the new text search. Each asset data is stored along with the associated CREATE transaction ID (asset ID). That data gets written when the containing block gets written to the bigchain table. [Pull Request #1460](https://github.com/bigchaindb/bigchaindb/pull/1460)
* Schema validation was sped up by switching to `rapidjson-schema`. [Pull Request #1494](https://github.com/bigchaindb/bigchaindb/pull/1494)
* If a node comes back from being down for a while, it will resume voting on blocks in the order determined by the MongoDB oplog, in the case of MongoDB. (In the case of RethinkDB, blocks missed in the changefeed will not be voted on.) [Pull Request #1389](https://github.com/bigchaindb/bigchaindb/pull/1389)
* Parallelized transaction schema validation in the vote pipeline. [Pull Request #1492](https://github.com/bigchaindb/bigchaindb/pull/1492)
* `asset.data` or `asset.id` are now *required* in a CREATE or TRANSFER transaction, respectively. [Pull Request #1518](https://github.com/bigchaindb/bigchaindb/pull/1518)
* The HTTP response body, in the response to the `GET /` and the `GET /api/v1` endpoints, was changed substantially. [Pull Request #1529](https://github.com/bigchaindb/bigchaindb/pull/1529)
* Changed the HTTP `GET /api/v1/transactions/{transaction_id}` endpoint. It now only returns the transaction if it's in a valid block. It also returns a new header with a relative link to a status monitor. [Pull Request #1543](https://github.com/bigchaindb/bigchaindb/pull/1543)
* All instances of `txid` and `tx_id` were replaced with `transaction_id`, in the transaction model and the HTTP API. [Pull Request #1532](https://github.com/bigchaindb/bigchaindb/pull/1532)
* The hostname and port were removed from all URLs in all HTTP API responses. [Pull Request #1538](https://github.com/bigchaindb/bigchaindb/pull/1538)
* Relative links were replaced with JSON objects in HTTP API responses. [Pull Request #1541](https://github.com/bigchaindb/bigchaindb/pull/1541)
* In the outputs endpoint of the HTTP API, the query parameter `unspent` was changed to `spent` (so no more double negatives). If that query parameter isn't included, then all outputs matching the specificed public key will be returned. If `spent=true`, then only the spent outputs will be returned. If `spent=false`, then only the unspent outputs will be returned. [Pull Request #1545](https://github.com/bigchaindb/bigchaindb/pull/1545)
### Removed
* The `server.threads` configuration setting (for the Gunicorn HTTP server) was removed from the default set of BigchainDB configuration settings. [Pull Request #1488](https://github.com/bigchaindb/bigchaindb/pull/1488)
### Fixed
* TODO: Pull Request #1450 fixed a bug but then it came back later? See [pull request #1470](https://github.com/bigchaindb/bigchaindb/pull/1470) ("#1450 unrevert")

### Notes
* There were many improvements to our Kubernetes-based production deployment template (and the associated documentaiton).
* There is now a [BigchainDB Ruby driver](https://github.com/LicenseRocks/bigchaindb_ruby), created by @addywaddy at [license.rocks](https://github.com/bigchaindb/bigchaindb/pull/1437).
* The [BigchainDB JavaScript driver](https://github.com/bigchaindb/js-bigchaindb-driver) was moved to a different GitHub repo and is now officially maintained by the BigchainDB team.
* We continue to recommend using MongoDB.
