This is about to get mdlrelease tool supporting multiple dev branches and allow it to release both weeklies and minors normally.
Note that these are the 2 types of releases that we are going to need over the next weeks. And this issue is, exclusively, about them.
Later, another issue (
MDLSITE-6223) will be in charge of covering all the remaining releases involving dev branches, basically, on-demand, beta, rc, major, on-sync, back-to dev.
