Release 2.23

[Tristan Gingold]

Hi,

I was rather busy before the summer and hence I didn't take the time to create a 2.22.1 release.
I can however schedule a release for this summer.  So my plan is:

* I will create the 2.23 branch this week and creating a pre-release just after.

* I plan to do the 2.23 release at the end of August or at the beginning of September (unless there is a blocking issue).

So, if you have big or large changes, it would be nice to wait a little bit.  And as usual, do not hesitate to test your favourite platforms.

Tristan.
