Mantis 1.0.8 has been released, but there is no ebuild for it. Looks like it's very minor fixes -- no big hurry. "Mantis 1.0.8 is a maintenance release for the 1.0.x stable releases branch. This release was mainly focused on fixing an application error that caused users to sometimes get a blank screen and some minor fixes that were requested by packagers for Linux distributions. It is a recommended updated for all 1.0.x users." -- http://www.mantisbt.org/
Thank you for notice. There was not official announcement and I missed new version. It's not bumped still as I encounter regression, that is reported upstream. Hope they'll help to resolve it.
At last I've bumped it. See http://www.mantisbt.org/bugs/view.php?id=8256 for some reasons, why it takes too long. A side note: I've added bundled-adodb USE flag in mantisbt. Now if you have this flag enabled it'll use adodb bundled with mantis itself, if disabled it'll have adodb dependency and will use system-wide adodb. Enjoy. :)
