Re: [tycho-user] tycho 0.13.0 released

[Max Rydahl Andersen <max.andersen@xxxxxxxxxx>]

btw. I hope you guys are on tycho-user/dev a lot of good things being discussed there ;)

including answer to my question about "download all of p2 repos" and the answer is that it doesn't download all, it just consider all in there as part of the target platform.

Alarmingly though there are users reporting that 0.13 increases their build times *alot* so we should look at that and report our findings at https://bugs.eclipse.org/bugs/show_bug.cgi?id=356888

This way you cant point you target-platform-configuration plugin to use it. I had no time to test this improvement yet: https://bugs.eclipse.org/bugs/show_bug.cgi?id=342808, but I will in a couple weeks.
