A few people have pinged about 1.19.1 source. I'm currently unable to publish to svn.secondlife.com - I'll get updates out when that's resolved. In the meantime, 1.19.1 release is identical to 1.19.1 RC 4, except for some version strings. RC4 source will generate a functionally identical binary. 1.20 pre-RC, including Dazzle, will appear shortly as well.
