Hi, A user perspective on this discussion:
I would be very, very keen on: - this: https://trac.osgeo.org/grass/ticket/2579 (as well as the simple python import that is under development) and - this: https://grasswiki.osgeo.org/wiki/ISO/INSPIRE_Metadata_Support and - this: https://trac.osgeo.org/grass/ticket/2750 and - this: https://trac.osgeo.org/grass/browser/grass/trunk/temporal/t.rast.what and - ... Personally, I perceive GRASS as stable by design and I very much share Markus N.`s view on GRASS being "my reliable number cruncher". Backwards compatibility is less of an issue for me, as everybody can update for free. A significant gain in storage, performance and functionality weighs much more for me... Summarizing: yes reliability is a very important quality of GRASS GIS. Yet, if you feel ready for a release I will embrace the new version (independent from its number), and am definitely willing contribute with testing release candidates...

Assuming stable means no major changes in the code base will happen, a releasebranch should be stable and at the same time become more robust (bugs being eliminated with every z release with GRASS x.y.z). > >> Stable typically means backport only of critical bugxfixes. > > > I do completely agree with this, and I agree that we have not been > careful enough and have succombed to the temptation of backporting > some new features.

The GRASS release policy is described in the GRASS release roadmap [0]. A release branch is identified by its major and minor version number. According to the GRASS release policy, a release branch should become more robust (have less bugs) with every revision. That implies that no new features are backported. Following this policy would imply more frequent releases of more robust GRASS versions, and earlier availability of new features in a release branch because developers would (should) push for trunk being released as a new release branch because nice new features are not allowed to be backported. > >> Therefore, in order to stick with the odd/even numbering meaning, G7 >> should have been released immediately as G71 to indicate a dev >> version.

A GRASS GIS release x.y.z means "new features, hopefully less bugs than in x.y.(z-1), but there can be new bugs".
