Eevee Rendering
One big issue was the inability to render quickly with the new Tesla T4 GPUs. This was certainly important, as these low-cost GPUs are great for rendering. All GPU rendering has been updated to fix these issues, and make it much faster. To give you an example on performance, I rendered CG Cookie's Treasure Chest Animation with a g4dn.xlarge instance on Barista 1.7.6, and spent a whopping $0.006 (yes, less than $0.01).
Cycles Rendering
It seems tile progress reporting broke sometime in Blender 3.x, so the log parser was updates to support the tile/sample rendering output from 3.x.
Blender Updated
The instances image has been updated with the latest version of Blender, so the new built-in default is now Blender 3.3.1.
Barista 1.7.5 Depreciation
Since 1.7.6 includes a new instance image, 1.7.5 will depreciate on November 7th.
Happy rendering!
