[Mono-dev] Heads up: Elimination of the 2.0 and 4.0 profiles

[Martin Thwaites]

Hi Miguel,

I think my preference would be to have the 3.x.x series continue (as
security fix only) with all the profiles, and essentially have it be a
legacy branch.  Then have the 4.x.x series by a .NET 4.5+ only code base.
I think it should continue if people are willing to support it, but the
contributors who don't want to have to support it (or don't have the time
to implement hacks for it) don't have to.

>From a communication perspective it would be easier to get across saying
that "From mono 4.0 onwards, we only support the 4.5 profile" rather than
3.11.x onwards as it's not as easy to remember which 3.x number it was when
it stopped.  A decision and a change like that does really feel "major" and
therefore warrant the change.

The other question I have is around the linux distros that ship mono as
standard (I think Ubuntu does).  Do you perceive this having an affect on
them, i.e. they will never ship 4.0 as it doesn't cater for .NET 2.0
applications and there are some core pieces that rely on it?

Thanks,
Martin
