=Long-term releases=

* We’ve managed to make 6-month releases
** No change in schedule time: we want to continue doing 6-months
** Modulo adjustments so we don’t release too close to vacation periods
* Release process is improving
** Ability to do package creation much more quickly
** Unification of packages with enterprise/commercial will also reduce workload
* How long should long-term releases be?
** More than every 2 releases
** Probably every 18-24 months (3 or 4 releases)
* First <span class="caps">LTS</span> release should be either 5.3 or 5.4
** Digia wants to do a business check first and will let us know
** 5.3 is a good candidate because we focused on stability
* Doing <span class="caps">LTS</span> buys us a few benefits:
** We can deprecate platforms and compilers after the <span class="caps">LTS</span> release
** Targets to be dropped as soon as feasible:
*** Windows XP
*** OS X 10.6
*** <span class="caps">MSVC</span> 2008
*** <span class="caps">GCC</span> < 4.6
* Procedure:
** Bugs to be fixed should be security bugs, P0, P1
*** P2 can be fixed, exceptionally, if no workaround is possible
** Fix is applied to the <span class="caps">LTS</span> branch and then merged to the next releases
** Releases should be based on amount of changes made, like what we’re doing for 4.8
