Questions:
* Patch release date ?
** Jc: Considering I will be travelling next week (March 12 to 19), it will most likely happen at the end of the month.
* Is it okay to update version of ITK (r24932, r24933, r24947 and r24892) ? 
** Jc: Considering that (1) the ITK version update consists of around ~500 ITK commits andn (2) it also requires substantial updates in Slicer transform code and BRAINSTools. These are outside of the scope of this patch release.

= Updates =

* Nicole: SlicerOpenCV extension has been added to the extension index
* Andras: Addition of new layout including a table node viewer
* Jc: We now have dedicated Amazon resources for Slicer and ITK testing. Corresponding resources will be managed using Jenkins and will initially be used for Continuous testing.

* David Warren (from VTK list): Volume rendering of brain volumes with overlays : https://bitbucket.org/dewarrn1/vtk_render_demo

= Conclusion =
* Steve and Nicole reviewed patch plans.  Agreed that 4.5.2 should contain the 5 suggested patches.  We were a bit unclear on the question of updating ITK - @jcfr are you saying that BRAINSTools and Slicer Transforms would need fixing if we update ITK?  If so, we suggest not updating ITK for the patch.
