That's probably fine with me, except 2 moments that seem to require "out of band" releases: 1. Something should be done with current release. As I said, it's not an option to postpone it to 5.10, however it also cannot be released as 5.9.1 because there are API additions which I don't want to revert (in particular because these APIs were already shipped by Linux distros that chose to provide TP4 and TP5). Also there is a change in QDataStream format of QWebHistory. 2. Security updates. WebKitGTK team provides several patch releases for each stable branch, which contain only fixes for bugs and security issues, and towards the end of release life cycle they became primarily security updates. I think we should be able to release such updates ASAP, by making up some tag name and scheduling custom build against newest patch release of Qt. > _______________________________________________ > Development mailing list > [email protected] > http://lists.qt-project.org/mailman/listinfo/development -- Regards, Konstantin _______________________________________________ Development mailing list [email protected] http://lists.qt-project.org/mailman/listinfo/development
