1 - Changelog for OpenStack 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!
