This release focuses mostly on optimizations, saving both memory and render times for general rendering, and more specifically for displacement and caustics.

Some of the highlights:

• 2.5D displacement: saves significant memory and reduces parsing times
• Caustics improvements: saves significant memory and renders faster, plus other improvements
• Overall memory, parsing time, and render time savings for all scenes (no changes required!)
• New hair and skin materials added to the Material Library
• Hair rendering (Max native, Ornatrix, or Hair Farm) needs less memory
• Various quality of life improvements, UI tweaks, and bug fixes!

Read full details about all the above, plus everything else there isn't space to mention, over in the blog post.
