There was a server roll to the main channel. This package has a fix for BUG-11163 llHTTPRequest – returns 400 from some sims and not others and minor internal improvements.
There is no new package for the RC channels. They are running the same package as the main channel.
No word on whether we will have a new package rolling to the RC channels next week.
In the article on news from the Third Party Viewer Dev’s meeting I mentioned the current viewer versions. Nothing has changed since yesterday. See: Second Life Third Party Viewer Meeting 4/8.
