Mari versions

v3.3 [Jun 21, 2017]
Shaders now require fewer recompilations (the spinning wheel) when performing certain repeated tasks, reducing the waiting time between performing an action and viewing the final rendered shader.
An option has been introduced to run all colorspace transformations on the GPU, which improves the process speed of baking paint to disk.
After performing a marquee selection, you can now lift the texture from the current paint target to the paint buffer for further manipulation.
Mari now combines multiple textures into one optimized unit, so that you can work on projects with a higher level of complexity, without reaching graphics capacity limits.
You can now bake the Bake Point nodes that have never been baked before or are out-of-date, directly in the Node Graph by right-clicking and selecting Edit > Bake Points > Smart Bake And Update.
Mari now includes new channel presets for multiple workflow and shader types.

v1.6 [Dec 20, 2012]
AMD graphics card support Radeon HD 7850, HD 7950 and FirePro W7000, W8000 and W9000 have been officially tested and added to the Tested Graphics Cards list.
Vector Paint and Vector Inspector tools give you the ability to create flow and normal maps to specify the direction of paint flow on a model, and to monitor changes easily with the inspector.
Vector paint blending modes help create flow and normal maps with the specialised Vector Paint tool.
