= Summary =
 
 
 
The [http://www.slicer.org/pages/Acknowledgments community] of Slicer developers is proud to announce the release of '''Slicer {{documentation/version}}'''.
 
 
 
* Slicer {{documentation/version}} introduces
 
** An improved App Store, known as the Extension Manager, for adding plug-ins to Slicer. More than 80 plug-ins and packages of plug-ins are currently available.
 
** Close to 150 feature improvements and bug fixes have resulted in improved performance and stability.
 
** Improvements to many modules.
 
 
 
* Click here to [http://download.slicer.org/ download] Slicer {{documentation/version}} for different platforms and find pointers to the source code, mailing lists and the bug tracker.
 
* Please note that Slicer continues to be a research package and is not intended for clinical use. Testing of functionality is an ongoing activity with high priority, however, some features of Slicer are not fully tested.
 
* The [[Documentation/{{documentation/version}}/Training|Slicer Training]] page provides a series of tutorials and data sets for training in the use of Slicer.
 
 
 
[http://www.slicer.org slicer.org] is the portal to the application, training materials, and the development community.
