Bumped version to 1.11.1

I like the 'DOTSDOWN' icon better, so I keep using it in Blender ≤ 2.79.

 # Blender Cloud changelog
 
+
+## Version 1.11.1 (2019-01-04)
+
+- Bundled missing Texture Browser icons.
+
+
+## Version 1.11.0 (2019-01-04)
+
+- Texture Browser now works on Blender 2.8.
+- Blender Sync: Fixed compatibility issue with Blender 2.8.
+
+
+## Version 1.10.0 (2019-01-02)
+
+- Bundles Blender-Asset-Tracer 0.8.
+- Fix crashing Blender when running in background mode (e.g. without GUI).
+- Flamenco: Include extra job parameters to allow for encoding a video at the end of a render
+  job that produced an image sequence.
+- Flamenco: Compress all blend files, and not just the one we save from Blender.
+- Flamenco: Store more info in the `jobinfo.json` file. This is mostly useful for debugging issues
+  on the render farm, as now things like the exclusion filter and Manager settings are logged too.
+- Flamenco: Allow BAT-packing of only those assets that are referred to by relative path (e.g.
+  a path starting with `//`). Assets with an absolute path are ignored, and assumed to be reachable
+  at the same path by the Workers.
+- Flamenco: Added 'blender-video-chunks' job type, meant for rendering the edit of a film from the
+  VSE. This job type requires that the file is configured for rendering to Matroska video
+  files.
+
+  Audio is only extracted when there is an audio codec configured. This is a bit arbitrary, but it's
+  at least a way to tell whether the artist is considering that there is audio of any relevance in
+  the current blend file.
+
+
+## Version 1.9.4 (2018-11-01)
+
+- Fixed Python 3.6 and Blender 2.79b incompatibilities accidentally introduced in 1.9.3.
+
+
+## Version 1.9.3 (2018-10-30)
+
+- Fix drawing of Attract strips in the VSE on Blender 2.8.
+
+
+## Version 1.9.2 (2018-09-17)
+
+- No changes, just a different filename to force a refresh on our
+  hosting platform.
+
+
 ## Version 1.9.1 (2018-09-17)
 
 - Fix issue with Python 3.7, which is used by current daily builds of Blender.
