The features for Articles is now more or less frozen, the only changes will now only be bug fixes and minor features, etc. This is to allow work to Articles v2 to begin, which will have more features and will be written specifically for XOOPS 2.2.x.
Articles v1.0 has been tried on XOOPS v2.2.3, and appears to be fully functional, even though it wasn't written with 2.2.x in mind.
