[GRASS5] GRASS development roadmap proposal

[Bernhard Reiter]

Thanks for the proposal, it is a good idea to work on a roadmap.

We need to think in development lines 
or as I often write series. 
Your proposal below is not written to show the development lines.

Certainly we should have 5.0.3 as bug-fix releases.
We might also have further 5.0.x releases which IMO 
should also be bug fix releases.

I did not follow the datum discussions in detail.
What do you mean with: The results will be different?

Another idea would be to make in an experiemental add-on package
to 5.0.x if the datum transformation support is ready for this.


It is clear that the 5.0.x serious has to transform into the
5.1.x serious which then transforms into 5.2.x at some point
where 5.0.x support hopefully can be discontinued.

The renaming part (5.0 HEAD -> 5.3.0 and 5.1.0 -> 5.7.0) suggested
will cause confusion. I advise against it.
