Release Notes

This page provides high-level overviews of the dependencies and features that are supported by each revision in every stable release.

To learn more about the different release tracks and channels, see the Juju documentation about channels.

To see all releases and commits, check the Charmed MySQL Releases page on GitHub.

Dependencies and supported features

For a given release, this table shows:

• The MySQL version packaged inside

  This charm still supports older versions of Juju down to 2.9. See the Juju section of the system requirements for more details.

For more details about a particular revision, refer to its dedicated Release Notes page. For more details about each feature/interface, refer to the documentation linked in the column headers.

Architecture and base

Several revisions are released simultaneously for different bases/series using the same charm code. In other words, one release contains multiple revisions.

If you do not specify a revision on deploy time, Juju will automatically choose the revision that matches your base and architecture.

If you deploy a specific revision, you must make sure it matches your base and architecture via the tables below or with juju info
