MonoDevelop 0.15 Released

MonoDevelop is a GNOME IDE primarily designed for C# and other .NET languages. For details and screenshots see the Release Notes.

Some highlights:

• Configurable keybindings (with Emacs keybindings support).
• Localization support: integrates support for creating international applications (using gettext) and translating existing applications.
• Makefile generation: it can now generate plain Makefiles or Autoconf/Automake makefiles for projects.
• Header manager: for adding templates to your source code.

Plus various usability improvements all around (IDE, GUI Designer) and many of the reported bugs have been fixed.
