== What happen to the existing Slicer GitHub repository ? ==

Between 2011 and March 2020, Slicer sources were maintained in a SVN repository automatically mirrored on GitHub. To speedup time required to checkout Slicer source code, large data files have been removed from the Slicer commit history.

To ensure existing references to both Git SHA and Pull Requests are reachable, the mirrored GitHub repository has been renamed to https://github.com/Slicer/SlicerGitSVNArchive

== What is SlicerGitSVNArchive repository ? ==

This corresponds to the original GitHub repository that was a mirror of the Slicer SVN authoritative repository. The former <b>Slicer/Slicer</b> repository was renamed into <b>[https://github.com/Slicer/SlicerGitSVNArchive Slicer/SlicerGitSVNArchive]</b>

== What happen to SVN repository ? ==

Until September 2020, SVN server http://svn.slicer.org hosting the Dart, NAMICSandBox, Slicer3, Slicer3-lib-mirrors and Slicer4 repositories will remain available.

The web server http://viewvc.slicer.org/ will be converted into a static html website.

== What happen to Slicer Mantis issue tracker ? ==

Mantis issue tracker has been retired and new issues should be created here: https://github.com/Slicer/Slicer/issues

For every mantis issues, a GitHub issue has been created with a link to the retired mantis tracker.

To support this, the following redirections have been established:
* https://issues.slicer.org redirects to https://github.com/Slicer/Slicer/issues
* https://mantisarchive.slicer.org redirects to the retired mantis issue tracker
* <tt><nowiki>https://issues.slicer.org/XXX</nowiki></tt> redirects to <tt><nowiki>https://github.com/Slicer/Slicer/issues/XXX</nowiki></tt>
* <tt><nowiki>https://issues.slicer.org/view.php?id=XXX</nowiki></tt> redirects to <tt><nowiki>https://github.com/Slicer/Slicer/issues/XXX</nowiki></tt>

Slicer4 project has been disabled in Mantis. This means that no issues will be visible on the main page and that user will not be able to create issues in mantis.

== How to update existing Slicer checkout ? ==

TBD

== How to update existing Slicer custom application ? ==

To ensure Slicer sources can be checked out using the provided Git SHA, in <tt>CMakeLists.txt</tt> file, replace lines like:

  GIT_REPOSITORY git://github.com/Slicer/Slicer

with

  GIT_REPOSITORY git://github.com/Slicer/SlicerGitSVNArchive
