IdP 3.1.2 release plan

[Tom Zeller]

I suggest we release IdP 3.1.2 one week from today, on Wed first of July.

Schedule :
Late Friday June 26 : code freeze starts
Early Monday June 29 : really frozen, quiet day
Tuesday June 30 : tag 3.1.2, build distribution and Windows installer,
final testing
Wednesday July 1 : announce

This release should be easier than the previous since we are not
releasing any dependencies, however, I like the general schedule.

Of course, comments welcome.

Thanks !
