MITK Release Cycle

MITK Release Cycle

The MITK toolkit is released in snapshots every 3-4 months. The focus of the snapshots is the toolkit. They contain the source code and binary packages of an application for image viewing, measurement and segmentation.

Apart from the snapshots several projects release specific application versions and configurations like Diffusion Imaging 2012.

Release schedule

Name	Status	Release date	Feature freeze	Comments
MITK 2012.09	Planned	21.09.2012	05.09.2012
MITK 2012.06	Released	15.06.2012	30.05.2012
MITK 2012.02	Released	07.02.2012	01.02.2012	Test release, no binary packages, only source

Version scheme

Toolkit versions of MITK consist of three components, defined in CMake/mitkSetupVariables.cmake and accessible through MITKConfig.cmake and mitkConfig.h

• MITK_VERSION_MAJOR: Year of the release
• MITK_VERSION_MINOR: Month of the release (two digits)
• MITK_VERSION_PATCH: Numbering of releases in this month:
  • .0 is the first one,
  • .2 the second one (based on .0, not HEAD)
  • odd numbers specifying development versions

2012.02.0 is the first snapshot release in February 2012. Bugfix releases for this will be called 2012.02.2, 2012.02.4 ... .

Why is there no MITK 1.0?

MITK as a toolkit is mature and usable for some time now. Somehow we "missed" releasing a specific version as 1.0 . Since 1.0 mostly has a political and cultural meaning (see Wikipedia on this) we decided to skip 1.0 and move to a date-based versioning scheme for the toolkit.

Still there will be 1.0 releases of applications based on MITK.

Old versions

The old versioning scheme created some confusion, so we will give a short overview on the existing versions so far:

0.10, 0.12, 0.12.2, 0.14	Official releases
0.99.x	Snapshot releases that were intended as previews of MITK 1.0 . These are completely outdated, see above
0.15.1	This is the current master/trunk/HEAD release, following our old versioning scheme. As soon as we have completely moved to the new scheme this number will not appear anywhere anymore.

Other versions

Tags named "releases/snapshot-YYYYMMDD" are usually created for projects using MITK which need to permanently mark a specific version of MITK. Please be aware that these releases are not always fully tested since most projects only use parts of MITK.

Version control

New versions will be put in branches named releases/2012-02 during development and tagged after the release. More detailed information will be put here and on the download page.
