[QGIS-Developer] [Qgis-user] Thoughts on QGIS Development and LTR Releases

Sat Feb 29 20:13:42 PST 2020

Hi Groene,

I agree that the Road map is not easy to understand. Just to clarify things
(I hope):

The current LTR is 3.10 (currently at 3.10.3). It only became LTR in
February although its first release was done in october (3.10.0). The idea
is to let it mature (and have a broader usage and tests) for at least 4
months before it becomes LTR.

This means that for the next 12 months, more or less every month a new
patch release will come out. That will be 3.10.4, 3.10.5 and so on. Only
bug fixes are allowed on these releases, no new features.

If there is a version with some extra number (e.g. 3.4.13-3) it means that
something happened during packaging of the patch release, requiring a new
package/installer to be created. You should always try to use the latest
version of the LTR version, which should be the most stable one.

Hope it helps.
