This document should enlighten somewhat: http://www.mozilla.org/roadmap.html
Here is the gist for OS/2. 99% of OS/2 fixes are bug fixes so they are valid for both 1.0 (the branch) and 1.1 (the trunk) We attempt to put them in both places. If 1.0.1 is released and not all OS/2 fixes have made it into the 1.0.1 tree, I will put those fixes onto my private build before I create the official 1.0.1. So any fixes we make will be in both a released 1.0.1 (the branch) and in 1.1 (the trunk) If you want to have all the lastest OS/2 specific fixes now, you have to use a trunk build which can sometimes be unstable, although not every fix has been checked in yet. ftp://ftp.mozilla.org/pub/mozilla/nightly/latest/ If you want to use a stable build with most OS/2 fixes, use a branch build ftp://ftp.mozilla.org/pub/mozilla/nightly/latest-1.0/ (note there are no OS/2 build in there right now, we are working to get it resolved.) The last Os/2 branch build is in: ftp://ftp.mozilla.org/pub/mozilla/nightly/latest-1.0.0/ As to why we are working on both branch and trunk, the answer is very simple. The trunk is the future of Mozilla, the branch is where current product releases are going to come from. Mike Kaply IBM Mozilla Advocate
