See the PR Checklist of the main Keycloak server repository for the info.

The Keycloak client currently does not have a bot, so after merging a PR, it is also good to double-check that the related GH issue has a correct label set to the upcoming version of Keycloak client. For example if next version of the Keycloak client release would be 26.0.5, make sure that the issue has label like release/26.0.5 added to it. It should be added manually for now.
