This night, we got an Update of Allura, the platform behind CODESYS Forge, to version 1.12.0. This version fixed a security issue in the global search. Before it was possible to see some of the private posts, sites or commit messages through the search. This is fixed now.
Beside that the main improvement was in the field of "user mentions". I would say, that this feature became mature after this release.
Not as part of the Allura update, but because of the CODESYS Forge upgrade, I enabled spell checking in the markdown editor.
