New features include a refine area brush, noise-aware adaptive sampling (works best with simple path tracing, not bidir, stick to simple MLT for that), a port of Mitsuba’s cloth shader, a MUCH faster bloom filter, an overhauled render queue, more efficient dispersion support, and of course, bug fixes. (including a memory leak with hybrid rendering, and a weird bug in v1.1 that could cause chunks of objects to disappear). Full release notes and download links for builds at the link above.
If you find any issues, let us know! 1.2 final should be out in the near future (depending on people’s holiday schedules and what issues come up).
Finally, no the fancy crazy-fast pure-GPU renderer is not included, that is still a work in progress and will be in v1.3 (or whatever we decide to call it).
