[RFC] Proposal for GtkSourceView 3.24, 3.50 and 3.90

[Sébastien Wilmet <swilmet gnome org>]

Hi,

GTK+ 3.90 is planned for March 2017:
https://blog.gtk.org/2016/09/01/versioning-and-long-term-stability-promise-in-gtk/

If everything goes fine, GtkSourceView 3.90 is also planned for March
2017, to follow the unstable version of GTK+.

Since it will be possible to break the GtkSourceView API (since it'll be
a new major version, fully parallel-installable), there is one big API
break planned: renaming the namespace from GtkSource to Gsv, see:
https://bugzilla.gnome.org/show_bug.cgi?id=755752

Here is a proposal to be able to port an application (more) smoothly to
GTK+ 4 and GtkSourceView 4:
https://wiki.gnome.org/Projects/GtkSourceView/TransitionToGtkSourceView4

The plan is to release in a few weeks the 3.24 version. Then 3.50 when
it's done, and then port the GtkSourceView code to GTK+ 3.90.

What do you think? Does it sound a good plan?

If there are no major disagreements, I can ask the GNOME release team
what they think, and then send an e-mail to the distributor-list if we
have the green light.
