As one more bit before the release here is a RC2 build.
It has only several noteworthy changes and some issues fixed.
A little but wanted feature still slipped in at this time: ability to make Schedule trigger skip triggering a build if the pending changes match specific pattern.
Please note that this build comes without bundled EAP license key (but you can still get one form previous EAP build if you wish :).
Want to get a preview of the almost ready TeamCity 6.0? Jump on the train.
BTW, if you happen to still have TeamCity 4.x installed, you might want to consider buying an upgrade before 6.0 comes out (you can count days now). This way you can still get upgrade discount and get 6.0 and (as with a usual license) get all following releases within a year included into the price.
