 # Blender Cloud changelog
 
+## Version 1.12 (2019-03-25)
+
+- Flamenco: Change how progressive render tasks are created. Instead of the artist setting a fixed
+  number of sample chunks, they can now set a maximum number of samples for each render task.
+  Initial render tasks are created with a low number of samples, and subsequent tasks have an
+  increasing number of samples, up to the set maximum. The total number of samples of the final
+  render is still equal to the number of samples configured in the blend file.
+  Requires Flamenco Server 2.2 or newer.
+- Flamenco: Added a hidden "Submit & Quit" button. This button can be enabled in the add-on
+  preferences and and then be available on the Flamenco Render panel. Pressing the button will
+  silently close Blender after the job has been submitted to Flamenco (for example to click,
+  walk away, and free up memory for when the same machine is part of the render farm).
+- Flamenco: Name render jobs just 'thefile' instead of 'Render thefile.flamenco.blend'.
+  This makes the job overview on Flamenco Server cleaner.
+- Flamenco: support Shaman servers. See https://www.flamenco.io/docs/user_manual/shaman/
+  for more info.
+- Flamenco: The 'blender-video-chunks' job type now also allows MP4 and MOV video containers.
+
+
+## Version 1.11.1 (2019-01-04)
+
+- Bundled missing Texture Browser icons.
