I'm not trying to start a war here and I guess this will be my only contribution to this thread so with the risk of being punished by the wicket community, I guess the speaker said like he said because wicket release numbering doesn't follow "normal" version numbering (with "normal" I mean what most other projects use). If you have x.y.z, then you should change x: if you have API breaks y: if you have new development, internal improvements or non critical bug fixes and there isnt an API break z: if you have to release a hot-fix for due to a serious bug.
Releases with this numbering will on the other hand require more maintenance. A z release should be made for all previous releases which contains the bug, provided that the 'old' release is still supported. It could be the last X number of y releases or perhaps all releases made the last number of X months. /J 2011/3/21 Martijn Dashorst <martijn.dasho...@gmail.com> > While we strive to keep binary compatibility between minor releases, > i.e. the z releases of an x.y.z release path, sometimes things slip > by.
