Changelog

Sourced from versions-maven-plugin's changelog.

2.6

• [Pull Request #252][pull-252]

  Thanks to Edward Maxwell-Lyte 2248005+edwardmlyte@users.noreply.github.com

  Minor spelling corrections

• [Fixed Issue 157][issue-157]

  Document the end of versioning limitations in Maven 3.x
  There may remain good reasons for defining custom versioning rules to
  let versions-maven-plugin apply, but at least not the old Maven 2.x
  limitation

• [Fixed Issue 256][issue-256]

  if initial and new version are equals, just display initial
  this means this is a plugin version that requires a Maven version that
  is not compatible with project minimum version, not really a proposed
  upgrade

• [Fixed Issue 237][issue-237]

  Thanks to Julian Di Leonardo DiJu519@users.noreply.github.com

  Adding parent processing to UseLatestVersion/UseLatestSnapshot/UseLatestRelease

• [Fixed Issue 190][issue-190]

  Thanks to Julian Di Leonardo DiJu519@users.noreply.github.com

  Fixing issue in update-child-modules, where root module's version was
  being used in all downstream children even when a child's parent was
  different.

• [Fixed Issue 219][issue-219]

  Added threadSafe=true to goals to prevent
  warning in Maven builds if you start Maven
  via: mvn -T ..

• [Fixed Issue 215][issue-215]
