Juju 2.6.5 Release Notes

The Juju team is proud to release Juju 2.6.5!

This release addresses several bugs and includes many general improvements.

Warning: pre-upgrade step highly recommended!

Due to the “log collections are now capped” change, the Juju team highly recommends checking the log collection size and pruning the collection.


Log collections are now capped

A new controller config value has been added model-logs-size. The default size is 20M. The old logs controller config values of max-logs-size and max-logs-age are deprecated and will be removed in 2.7. The conversion to capped collections happens automatically as part of the upgrade.

This addresses the issue where logs may be written into the database faster than we were pruning them, causing disk space issues on the controller machines.

This release includes more important fixes

  • LP #1824465 - New units fail provisioning; Juju 2.5.x switches to the Standard SKU (Azure provider)
  • LP #1632735 - Trying to bootstrap a region which doesn’t exist gives misleading error
  • LP #1833449 - juju register fails with usernames that contain uppercase letters
  • LP #1832779 - controller commands fail if there is no active controller
  • LP #1834017 - juju bundle upgrade failing with error “branch %q in model %q not found (not found)”
  • LP #1831527 - [gce] odd error messages are printed with kill-controller
  • LP #1831770 - Storage class error while deploying bundle
  • LP #1832783 - k8s init container spec parsing issue
  • LP #1832608 - Can’t use DNS for pods in StatefulSet
  • LP #1813886 - Unable to remove an offer, claiming removed relation still exists

Additional bugs fixed can be found in the milestone page.
