Template:Catznip R12.1 Release Cover
This update has rather a lot for a point release, the main being Animesh support from LL and a lot of quality of life, bug fixes, and performance improvements over R12.
A lot of work went into optimizing this Catznip release: we don't have recent hardware which makes it important additions don’t negatively impact the overall experience (FPS, etc). The same is true for features added by Linden Lab. Animesh in particular had a very negative impact on performance which we have largely negated with some extra work (including a fix from Beq for rendering rigged attachments with shadows enabled).
