 Supported Platforms  {#SupportedPlatformsPage}
 ===================
 
 MITK is a cross-platform framework and is available for the following platforms:
 
 - Windows
 - Linux/X11
 - Mac OS X
 
 Supported Platforms Details
 ---------------------------
 
 The MITK team provides support for the most frequently used platforms and continuously runs testing procedures
 to ensure compatibility. Due to the large amount of possible combinations of operating systems and compiler versions,
 we divide platform support into two test categories (Tier 1 and Tier 2).
 
 Although MITK may be built on a range of platform-compiler combinations, only a subset of these are actively
 support by the MITK development team.
 
 Tier 1 Platforms
 ----------------
 
 All Tier 1 platforms are continuously tested by our unit test suite and other internal testing procedures.
 Errors or bugs discovered in these platforms are prioritized and corrected as soon as possible.
 
 | Platform                            | Compilers
 | ----------------------------------- | -----------------------------
-| Ubuntu Linux 11.04 (64-bit)         | As provided by Ubuntu
-| Microsoft Windows 7 (32 and 64-bit) | MSVC 2008 SP1
+| Ubuntu Linux 12.04 (64-bit)         | gcc as provided by Ubuntu
+| Microsoft Windows 7 (64-bit)        | MSVC 2008 SP1
 | Apple Mac OS X 10.7 "Lion"          | LLVM-GCC as provided by Apple
 
 
 Tier 2 Platforms
 ----------------
 
 Tier 2 platforms may or may not be tested on a regular basis. Some Tier 2 platforms are used by individual
 members of the MITK development team on a daily basis and some only receive occasional testing. While we
 strive to support these platforms, MITK users should note that errors may be present in released versions
 as well as in the current master branch.

 contributions to improve support for other platforms.
