for the second time (i had the same issue when upgrading from 3.5.4 to 3.5.5) working on my (quite big) project after upgrading from 3.5.5 to 3.5.6 i get strange behaviors that ends with Unity crashing (out of memory most of the time)
i see the shaders flickering the textures… long times to change scenes…
so i was wondering: should i re-import every assets?
how can i be sure that everything is compiled perfectly for 3.5.6?
i see that there is a new PVR Texture Tool… should i recompress all my textures?
what is the mandatory todo list when upgrading to a minor release (hopefully to fix previous bugs) 
?
thank you
