As your login screen may have already told you, an optional viewer upgrade is available today. Announcing the Second Life 1.21 Viewer!
As many scripters are aware, this 1.21 viewer brings you the ability to compile scripts using Mono. (Learn more about Mono in a video tutorial by Torley Linden.) It also includes new LSL functions for “DetectedTouch” — features that will allow a prim to report where on its surface or texture that it has been clicked. This viewer is also a maintenance release: There are over 150 fixes that solve bugs from previous versions of Second Life. Many of these are small improvements that make existing features work more smoothly (like menus, Inventory offers, IM and Chat, Snapshots, Estate tools, and many more).
There is so much to list, please check out the Full release notes. There is a lot worth reading.
Please visit the Downloads page to download Viewer 1.21.6 — or simply click where your older viewer suggests you to upgrade to the new version.
Note: This viewer upgrade is OPTIONAL. You may still log in to Second Life with your current viewer 1.20.17.
You can discuss the release of this new Viewer here in the SL Forums.
Please of course continue to report new issues in the Issue Tracker and set the “Affects Version/s” to “1.21.” We can only investigate and solve issues that are reported in the Issue Tracker.
