Ubuntu 15.10 support date

Sometime around late July.
End of Life's tend to be more flexible than release time is.
So I don't think there is a definite set date, as of yet.

There will be a notice about the date here:
http://ubuntuforums.org/forumdisplay.php?f=13
when the time comes.

edit: Also since this is not about getting help, but rather a general inquiry about Ubuntu support time:
Thread moved to Ubuntu, Linux and OS Chat.
