0.1.0 (2017-06-28)

IMPORTANT NOTE

Starting with this release, TimescaleDB will now support upgrading between extension versions using the typical ALTER EXTENSION command, unless otherwise noted in future release notes. This important step should make it easier to test TimescaleDB and be able to get the latest benefits from new versions of TimescaleDB. If you were previously using a version with the -beta tag, you will need to DROP any databases currently using TimescaleDB and re-create them in order to upgrade to this new version. To backup and migrate data, use pg_dump to save the table schemas and COPY to write hypertable data to CSV for re-importing after upgrading is complete. We describe a similar process on our docs.

0.0.12-beta (2017-06-21)

High-level changes

• A major cleanup and refactoring was done to remove legacy code and
  currently unused code paths. This change is backwards incompatible
  and will require a database to be re-initialized and data re-imported.
  This refactoring will allow us to provide upgrade paths starting with
  the next release.
• COPY and INSERT commands now return the correct number of rows
• Default indexes no longer duplicate existing indexes
• Cleanup of the Docker image and build processBatches
• Chunks are now time-aligned across partitions
