I ran comparison tests between 2.249.1 and 2.249.2-rc in my environment over the weekend. The comparisons included varying versions of the trilead-api-plugin for agent connections (JENKINS-63790).
I detected no issues that were specific to 2.249.2-rc or that would block the release of 2.249.2.
Selection of specific plugin versions (like the trilead-api-plugin) is outside the scope of LTS testing and is left to Jenkins administrators. I'm running the 1.0.12 pre-release of that plugin successfully in cases where the 1.0.11 release was not consistently connecting cloud agents to my Jenkins controller.
