v0.3.0 * Support multiple stores via [libkv](https://github.com/docker/libkv) ([#102](https://github.com/sorintlab/stolon/pull/102)). Currently etcd and consul are supported. * Can use pg_rewind to sync slaves instead of doing a full resync ([#122](https://github.com/sorintlab/stolon/pull/122)). * The `--initial-cluster-config` option has been added to the `stolon-sentinel` to provide an initial cluster configuration ([#107](https://github.com/sorintlab/stolon/pull/107)). * A cluster config option for initializing the cluster also if multiple keepers are registred has been added ([#106](https://github.com/sorintlab/stolon/pull/106)). By default a sentinel won't initialize a new if multiple keepers are registered since it cannot know which one should be the master. With this option a random keeper will be choosed as the master. This is useful when an user wants to create a new cluster with an empty database and starting all the keeper together instead of having to start only one keeper, wait it to being elected as master and then starting the other keepers. * The `--discovery-type` option has been added to the `stolon-sentinel` to choose if keeper discovery should be done using the store or kubernetes ([#129](https://github.com/sorintlab/stolon/pull/129)). * Various options has been added to the `stolon-keeper` for setting postgres superuser, replication and initial superuser usernames and passwords ([#136](https://github.com/sorintlab/stolon/pull/136)). * Numerous enhancements and bugfixes. Thanks to all the contributors!

v0.4.0 Some cleanups and changes in preparation for release v0.5.0 that will receive a big refactor (with different breaking changes) needed to bring a lot of new features.

v0.5.0 This version is a big step forward previous releases and provides many new features and a better cluster management. * Now the configuration is fully declarative (see [cluster specification](doc/cluster_spec.md) documentation) ([#178](https://github.com/sorintlab/stolon/pull/178)). * Ability to create a new cluster starting from a previous backup (point in time recovery) ([#183](https://github.com/sorintlab/stolon/pull/183)) * Wal-e backup/restore example ([#183](https://github.com/sorintlab/stolon/pull/183)) * Better synchronous replication, the user can define a min and a max number of required synchronous standbys and the master will always block waiting for acknowledge by the required sync standbys. Only synchronous standbys will be elected as new master. ([#219](https://github.com/sorintlab/stolon/pull/219)) * Production ready kubernetes examples (just change the persistent volume provider) ([#215](https://github.com/sorintlab/stolon/pull/215)) * To keep an unique managed central configuration, the postgresql parameters can now only be managed only using the cluster specification ([#181](https://github.com/sorintlab/stolon/pull/181)) * When (re)initializing a new cluster (with an empty db, from an existing instance or from a backup) the postgresql parameters are automatically merged in the cluster spec ([#181](https://github.com/sorintlab/stolon/pull/181)) * Use only store based communication and discovery (removed all the kubernetes specific options) ([#195](https://github.com/sorintlab/stolon/pull/195)) * Ability to use TLS communication with the store (for both etcd and consul) ([#208](https://github.com/sorintlab/stolon/pull/208)) * Better standby monitoring and replacement ([#218](https://github.com/sorintlab/stolon/pull/218)) * Improved logging ([#187](https://github.com/sorintlab/stolon/pull/187)) Many other [improvements and bug fixes](https://github.com/sorintlab/stolon/milestone/4)

### v0.8.0 #### New features * Added support for etcd v3 api (using --store-backend etcdv3) ([#393](https://github.com/sorintlab/stolon/pull/393)) * Now the stolon-proxy has tcp keepalive enabled by default and provides options for tuning its behavior ([#357](https://github.com/sorintlab/stolon/pull/357)) * Added `removekeeper` command to stolonctl ([#383](https://github.com/sorintlab/stolon/pull/383)) * Added the ability to choose the authentication method for su and replication user (currently one of md5 or trust) ([#380](https://github.com/sorintlab/stolon/pull/380)) #### BugFixes * Fixed and improved db startup logic to handle a different pg_ctl start behavior between postgres 9 and 10 ([#401](https://github.com/sorintlab/stolon/pull/401)) * Fixed keeper datadir locking ([#405](https://github.com/sorintlab/stolon/pull/405)) and [many other](https://github.com/sorintlab/stolon/milestone/7) bug fixes and documentation improvements. Thanks to everybody who contributed to this release: AmberBee, @emded, Pierre Fersing

### v0.9.0 #### New features * The logs will be colored only when on a tty or when `--log-color` is provided ([#416](https://github.com/sorintlab/stolon/pull/416)) * Now the store prefix is configurable `--store-prefix` ([#425](https://github.com/sorintlab/stolon/pull/425)) #### BugFixes * Fixed keeper missing waits for instance ready ([#418](https://github.com/sorintlab/stolon/pull/418)) * Fixed etcdv3 store wrong get leader timeout causing `stolonctl status` errors ([#426](https://github.com/sorintlab/stolon/pull/426)) Thanks to everybody who contributed to this release: Pierre Fersing, Dmitry Andreev

### v0.13.0 #### New features * Add a `stolonctl` command to force fail a keeper ([#546](https://github.com/sorintlab/stolon/pull/546)) * Overcome PostgreSQL synchronous replication limitation that could cause lost transactions under some events ([#514](https://github.com/sorintlab/stolon/pull/514)) * Users can now define `archiveRecoverySettings` in the cluster spec of a standby cluster. One of the possible use cases is to feed the standby cluster only with archived logs without streaming replication. (See Upgrade Notes) ([#543](https://github.com/sorintlab/stolon/pull/543)) * Keeper: remove trailing new lines from provided passwords ([#548](https://github.com/sorintlab/stolon/pull/548)) #### Bug Fixes * Sort keepers addresses in `pg_hba.conf` to avoid unneeded postgres instance reloads ([#558](https://github.com/sorintlab/stolon/pull/558)) * Set `recovery_target_action` to promote when using recovery target settings [#545](https://github.com/sorintlab/stolon/pull/545)) * Fixed wrong listen address used in `pg_hba.conf` when `SUReplAccessStrict` mode was enabled ([#520](https://github.com/sorintlab/stolon/pull/520)) and [many other](https://github.com/sorintlab/stolon/milestone/12) bug fixes and documentation improvements. Thanks to everybody who contributed to this release. #### Upgrades notes. * The clusterspec `standbySettings` option as been replaced by the `standbyConfig` option. Internally it can contain two fields `standbySettings` and `archiveRecoverySettings` (see the clusterspec doc with the descriptors of this new option). If you're updating a standby cluster, BEFORE starting it you should update, using `stolonctl`, the clusterspec with the new `standbyConfig` option.
