Version numbering of Harmattan explained
Editor: Andrew Flegg
Nokia's N9 developer blog explains the XX.YYYY.WW... version format used for Harmattan version numbers, which should be familiar to Maemo developers: A typical version number is formatted as XX.YYYY.WW-#_PR_VVV where XX is the GSM Software Version Number (SVN), YYYY build year, WW build week, # release candidate serial number on that week, and VVV variant configuration code.For Nokia N9 the SVN number 10 stands for Harmattan 1.0, 20 for Harmattan 1.1, 22 for Harmattan 1.1.1 (Arabic) and 30 for Harmattan 1.2. For Nokia N950 Developer Device the first SVN number 1 stands for Harmattan 1.0, number 2 stands for Harmattan 1.1 and 3 stands for Harmattan 1.2 beta. This should be only of interest to developers, functionality should be tested for if a specific capability is required, not the version number.
