A few hours ago Linden Lab (LL) updated viewer-release from viewer-beta. The last couple weeks we have provided test viewers based on viewer-beta.
Hopefully, the bugs introduced by the Pathfinding merge are resolved. Pathfinding functionally is unknown and needs tested. Certainly, the parts of the feature that require a Havok sub-license will not work. This beta release is up to date with LL viewer-release with bug fixes related to upload of textures and mesh models. Thanks to Timo Gufler for reporting these bugs and referencing the Firestorm fixes.
Understandably, some users are tiring of the pace of updates. Hopefully, baring urgent crash fixes the pace will be more reasonable.
