Changelog for OpenStack Train

Upgrade of version Queens to Train

Changelog overview

The purpose of this upgrade is to take the OpenStack platform from the current “Queens” release to the “Train” release. This will include an intermediate upgrade to the “Rocky” release. The “Stein” release is skipped because it isn’t required.

  • No public APIs are deprecated by these upgrades
  • Support for TLS version 1.1 will be dropped during the upgrade to the “Train” release

Deprecations and dropped support

APIs

None of the public OpenStack APIs will be deprecated by the planned upgrades.

TLS

Support for TLS version 1.1 will be dropped during the upgrade to the “Train” release. This will cause issues for API clients only supporting TLS version 1.1 or below as connections will be rejected. Upgrade and check client configuration before the upgrades!

Horizon (Web UI)

You will no longer be able to download “OpenStack RC File v2” by clicking your username in the top right corner. Only “OpenStack RC File v3” will be available.

Visible changes (Horizon/web UI)

  • The “Overview” page will be divided into categories by resource type. It will also contain information about more resources.
  • “Server Groups” are now visible under the “Compute” heading.
  • “Consistency Groups” and “Consistency Groups Snapshots” have been replaced by “Groups” and “Group Snapshots” under the “Volume” heading.
  • It is now possible to manage “Application Credentials” under the “Identity” heading.

New features

The upgrades come with a lot of new features, such as:
