- [Release notes](https://github.com/jenkinsci/bom/releases)
- [Commits](https://github.com/jenkinsci/bom/compare/bom-2.138.1...bom-2.138.2)

Switches from internally maintaining a compilable version number for
each component to specifically use the version provided by Jenkins plugin
BOM 2.138.2.

Strategy change is inspired by a desire to move users onto the most
heavily tested plugin versions.  Users that don't want to update
dependencies are welcome to choose to remain with older versions of
this plugin.
