libgtksourceviewmm 0.3.0 is available

What is it ?

libgtksourceviewmm is a C++ wrapper for the gtksourceview widget
library. It offers all the power of gtksourceview with an interface
familiar to c++ developers, including users of the gtkmm library.

Content of the release
=============

This is a bug fix and feature release that breaks the API a little
bit, but that is for the good.
Users of 0.1.0 and 0.2.0 must recompile their applications, sorry.
GtkSourceViewMM is reaching a state where API/ABI stability will
become possible, though.
