The Firestorm team have released an optional update to the Firestorm 3 Mesh Beta release. The update is to deal with a couple of issues, as explained in the official blog post:
“A new bug was brought to our attention recently that effects region restarts while using our Metaharper skin in our Firestorm Mesh Beta. Basically, the region will fail to restart and be left in a state that only LL Support can fix. We traced the origin of the bug, fixed it and have updated our download files.
“If you are an Estate Manager who performs region restarts AND you use the Metaharper skin it is strongly advised that you download our updated version 126.96.36.19966 from our download links on this page. No other skin is effected by this bug. Alternatively, you can fix the issue yourself without installing this optional update by following the instructions listed on this page. http://wiki.phoenixviewer.com/doku.php?id=fs_region_restart_bug
“We have also patched a performance issue some people may be effected by which essentially drops performance when you have many IM windows open at once. If you have performance drops while having multiple IM windows open you may find an improvement with this optional update.
“If you do not fall into the above criteria there is no need for you to update or worry, aside from what’s listed above, nothing else has changed since our 188.8.131.5225 Mesh Beta.”
