    Changes since v1.2.0-beta.5.

    New features

    • Refs #568: measure attachment handoff and control restore in the crossing trace; slow-to-transfer attachment notice (bc3a624fa4)
    • #375: restore updateQueue unpause -- paused-at-creation threads (TextureFetch) never started; startup hang (e9a24fcda5)
    • Line Copy to Blinn up with Save and add a Save tooltip (47597e86b7)
    • Add mesh preview colors and a UV guide (1d3f7b51e7)
    • Add Cube, Hexagon and User Defined physics presets (0a032b1ca9)
    • Add configurable LOD suffixes to the mesh uploader (5181d3708c)

    Fixes

    • Fixes #571: sliders with a value readout are typeable by default; typed values clamp+snap; show value on FOV/distance/BG-FPS/max-animated-avatars sliders (c7de71bd09)
    • Fixes #573 regression: decimated rigged steps never stand in for a source they cannot replace (260fbe56d0)
    • Fixes #577: dock the Texture panel beside the Build window while picking faces in the Links tab (5f8cd976a1)
    • #568: CROSSING_SCOPE drops the function-local LLTrace block timer (late-registered handle overran accumulator buffers: memory corruption / crash at world init) (fddea8371d)
    • Fixes #312: region object cache file I/O on a serial I/O thread (68e8ea3a77)
    • #381: public setter for the audio queued hint (compile fix) (1721149cfc)
    • Fixes #323: LLSurface::idleUpdate dirties the parcel overlay only when heights change (88b44ee7c5)
    • Fixes #321, refs #378: VO cache map unordered, per-frame waiting list a reused vector (2cab619f32)
    • Fixes #322: createVisibleObjects checks its time budget every 8 creations (2c91894ff8)
    • Fixes #324: drop the GL render-stride LOD from LLSurfacePatch::updateVisibility (3ace2e69bc)
    • Fixes #376 (wire format): binary LLSD, versioned length-prefixed pipe frames (92abcc96e0)
    • Fixes #381: concurrent sound fetches (4 max, per-transfer timeout), 4 Hz idle transfer scan, skip queued/sync passes and second channel update when idle (cb8a65267f)
    • Fixes #387: advance gFrameTime/gFrameTimeSeconds/gFrameIntervalSeconds and world clock at the start of post-startup idle, not inside LLViewerObjectList::update (59860ad36e)
    • Fixes #386: bound glib pump slice to 4 ms/frame (was 66 ms); getenv already cached (eba3f0a3bc)
    • Fixes #383: watchdog entry stays registered, pause/resume toggles an atomic instead of set erase/insert under mutex (a1c51e5fe7)
    • Fixes #319: stack ExtraParams buffer, skip unchanged hover text and name-value list re-apply (region lookups now O(1) via #320) (ed364def94)
    • Fixes #382: cache floater instance lists for per-frame polls (block_timers, build, scene_load_stats, moveview); mainloop pump already cached (b18fbfe757)
    • Fixes #317: orphan children keyed by parent (O(1) findOrphans), purged on region removal (a5cc7f65ee)
    • Fixes #370: bounded LRU parsed-XUI cache (ordered deep copy on hit, invalidated via LLDir skin generation), memoize base-lang filename lookup; deepCopy now preserves child order (c5fbc73c24)
    • Fixes #379: spend frame headroom on a backlogged main-thread reply queue (more while loading) (c572bd01e1)
    • Fixes #311: zero-copy var data + single lookup per field in decodeData, flat index in LLIndexedVector (fc8fd27b74)
    • Fixes #380: drop dependency-free listener names from event-pump dep graph; amortized prune of dead connections (5ea0490a6a)
    • Fixes #365: avatar picker near-me repopulate throttled to 4 Hz while names resolve (focus theft already guarded in tree) (46ba72180e)
    • Fixes #361: throttle hover pickImmediate to mouse/modifier/camera change or 100ms; pick serial guards against intervening picks (f9d2daa245)
    • Fixes #368: debounce persistent notification saves, prune dead history (3dee8ffff2)
    • Fixes #314: skip texture-list lookup in setTETexture when the TE id is unchanged (6ef9f433e5)
    • Fixes #313, Fixes #310: fixed-array extra-param slots; full updates only fire handlers when data changed (4f4666b4b8)
    • Fixes #360: hover-set traversal carries screen origin down the tree (no per-view ancestor walk), profile zone (3922cfe657)
    • Fixes #375: post queued-thread update lambda only for overriding subclasses; drop dead per-frame pause calls (85faf2f058)

    • Fixes #374: LLEventTimer flat registry walked without allocation or weak_ptr locking (39e8f199ec)

    • Fixes #441: projector shadow-map acne (receiver-plane depth bias + geometric normal offset) (7a1264d04b)
    • Legacy emissive-mask alpha mode: diffuse alpha masks glow (Fixes #515) (abc06fe0f7)
    • Name tags: deep occlusion bias for avatar tags so the avatar's own animated geometry does not flicker its tag. Fixes #513 (537c853201)
    • Mouselook: own hidden attachments are not pickable (#554) (c7c9e2fcda)
    • Fix rotated transforms in Copy to Blinn-Phong (98bb9e1518)
    • Fix LOD suffix preset selection (605b4d2e20)
