+## [2.0 Beta 6] - 2018-09-17
+
+Tag name: v2.0.0b6
+
+### Added
+
+* [New documentation about privacy and handling private data](https://docs.bigchaindb.com/en/latest/private-data.html). [Pull request #2437](https://github.com/bigchaindb/bigchaindb/pull/2437)
+* New documentation about log rotation. Also rotate Tendermint logs if started using Monit. [Pull request #2528](https://github.com/bigchaindb/bigchaindb/pull/2528)
+* Began implementing one of the migration strategies outlined in [BEP-42](https://github.com/bigchaindb/BEPs/tree/master/42). That involved creating a more general-purpose election process and commands. Pull requests [#2488](https://github.com/bigchaindb/bigchaindb/pull/2488), [#2495](https://github.com/bigchaindb/bigchaindb/pull/2495), [#2498](https://github.com/bigchaindb/bigchaindb/pull/2498), [#2515](https://github.com/bigchaindb/bigchaindb/pull/2515), [#2535](https://github.com/bigchaindb/bigchaindb/pull/2535)
+* Used memoization to avoid doing some validation checks multiple times. [Pull request #2490](https://github.com/bigchaindb/bigchaindb/pull/2490)
+* Created an all-in-one Docker image containing BigchainDB Server, Tendermint and MongoDB. It was created for a particular user and is not recommended for production use unless you really know what you're doing. [Pull request #2424](https://github.com/bigchaindb/bigchaindb/pull/2424)
+
+### Changed
+
+* The supported versions of Tendermint are now hard-wired into BigchainDB Server: it checks to see what version the connected Tendermint has, and if it's not compatible, BigchainDB Server exits with an error message. [Pull request #2541](https://github.com/bigchaindb/bigchaindb/pull/2541)
+* The docs no longer say to install the highest version of Tendermint: they say to install a specific version. [Pull request #2524](https://github.com/bigchaindb/bigchaindb/pull/2524)
+* The setup docs include more recommended settings for `config.toml`. [Pull request #2516](https://github.com/bigchaindb/bigchaindb/pull/2516)
+* The process to add, remove or update the voting power of a validator at run time (using the `bigchaindb upsert-validator` subcommands) was completely changed and is now fully working. See [issue #2372](https://github.com/bigchaindb/bigchaindb/issues/2372) and all the pull requests it references. Pull requests [#2439](https://github.com/bigchaindb/bigchaindb/pull/2439) and [#2440](https://github.com/bigchaindb/bigchaindb/pull/2440)
+* The license on the documentation was changed from CC-BY-SA-4 to CC-BY-4. [Pull request #2427](https://github.com/bigchaindb/bigchaindb/pull/2427)
+* Re-activated and/or updated some unit tests that had been deacivated during the migration to Tendermint. Pull requests [#2390](https://github.com/bigchaindb/bigchaindb/pull/2390), [#2415](https://github.com/bigchaindb/bigchaindb/pull/2415), [#2452](https://github.com/bigchaindb/bigchaindb/pull/24), [#2456](https://github.com/bigchaindb/bigchaindb/pull/2456)
+* Updated RapidJSON to a newer, faster version. [Pull request #2470](https://github.com/bigchaindb/bigchaindb/pull/2470)
+* The Java driver is now officially supported. [Pull request #2478](https://github.com/bigchaindb/bigchaindb/pull/2478)
+* The MongoDB indexes on transaction id and block height were changed to be [unique indexes](https://docs.mongodb.com/manual/core/index-unique/). [Pull request #2492](https://github.com/bigchaindb/bigchaindb/pull/2492)
+* Updated the required `cryptoconditions` package to a newer one. [Pull request #2494](https://github.com/bigchaindb/bigchaindb/pull/2494)

+
+### Notes
+
+The docs section titled "Production Deployment Template" was renamed to "Kubernetes Deployment Template" and we no longer consider it the go-to deployment template. The "Simple Deployment Template" is simpler, easier to understand, and less expensive (unless you are with an organization that already has a big Kubernetes cluster).
