+3.5.91 - Sept 3rd, 2012
+=======================
+
+Changes since 3.5.90:
+
+- Download OS logos on demand instead of shipping them in gnome-boxes or
+  in a non-free package.
+- Allow to customize box memory and maximum disk size before creating it.
+- More responsive box removals.
+- Make stopped/saved boxes easier to distinguish. Saved boxes show a
+  grayed out thumbnail of their display and stopped boxes show a black
+  screen.
+- Add the ability to use an additional ISO with extra Windows drivers for
+  use during unattended installs. For now, Boxes can use it to install
+  the Windows system to a virtio disk. It also needs to be made available
+  manually (this will be improved at a later point), 'make win-tools.iso'
+  can be used to download it,
+  http://git.gnome.org/browse/gnome-boxes/commit/?id=af09bc77c5 explains
+  what to do with it.
+- Tweak auto-hiding of fullscreen toolbar.
+- Improve box display scaling (when using a very recent spice-gtk).
+- Various UI fixes and improvements.
+
+- Added/updated translations:
+  - Assamese
+  - Galician
+  - Greek
+  - Hebrew
+  - Lithuanian
+  - Norwegian bokmÃl
+  - Polish
+  - Russian
+  - Simplified Chinese (zh_CN)
+  - Spanish
+  - Traditional Chinese (Hong Kong and Taiwan)
+  - Vietnamese
