[Kexi-devel] Handling of splitted Calligra repos and API changes

Mon Aug 31 13:38:49 UTC 2015

I am OK with Monday. We'd need to adjust to this day when we prepare
releases. E.g. tagging was on Saturday so far, now it would make sense just
after the Monday BIC, right?

Also, am I allowed to delete the kexi-framework* branches in the
calligra.git origin?
