Code::Blocks is a free, open-source, cross-platform IDE that supports multiple compilers including GCC, Clang and Visual C++.

The versioning scheme was changed to that of Ubuntu, with the major and minor number representing the year and month of the release.

It also allows the user to debug their program by having access to the local function symbol and argument display, user-defined watches, call stack, disassembly, custom memory dump, thread switching, CPU registers and GNU Debugger Interface.

Some of Code::Blocks features are targeted at users migrating from other IDE's - these include Dev-C++, Microsoft Visual C++ project import (MSVC 7 & 10), and Dev-C++ Devpak support.

It can optionally use external makefiles, which simplifies interfacing with projects using the GNU or qmake build systems.
