Yesterday’s rollback on the Magnum RC channel meant that some potentially decent fixes to large groups were not unveiled. These fixes are designed to deal with issues such as large groups not loading, so you can’t change your preferences etc.
However, Linden Lab seem determined to get these fixes out into the wild one way or another, so they’ve designed a workaround. The workaround includes the sometimes used Snack release channel. This code has been unleashed on some sandboxes, to test the large group fixes you will need to use a development viewer, be a member of the Second Life beta group and visit one of the listed sandboxes. Which listed sandboxes you may be asking, well the full details (including how to join the Second Life beta group and how to get a development viewer) can be found in the forum thread started by Oskar (where you can leave constructive feedback), the thread is here.
However be warned, the reason Magnum was rolled back yesterday was largely due to a bug with llSensor() in the code, that bug exists on these regions.
This means that you should not rez breedables on snack release channel land. The potential to do damage to your breedables on snack release channel land is so large, that under the known issues in the release notes it states:
“May cause uncontrollable weeping”
You have been warned! However do not panic, snack release channel code is not on your land, well unless your land is one of the sandboxes listed in Oskar’s thread!
