    Slipstream Beta 1.3.0.9 -- v1.3.0-beta.9 (7f0491d552).

    Linux x86_64 (glibc >= 2.38, x86-64-v2 CPU): *_x86_64.tar.xz
    Ubuntu 24.04+ / Debian 13+ / Mint 22+: *_amd64.deb (sudo apt install ./)
    Windows x64 (unsigned; SmartScreen: More info > Run anyway): *_Setup.exe installer, or *_win64.zip to unpack anywhere

    Changes since v1.3.0-beta.8.

    New features

    • Cluster LOD stream: bound the new unregister paths, re-offer refused writes (a623bd544c)

    Fixes

    • Cluster stream: drop the duplicated poolPages() accessor (merge fix) (1838cad879)
    • Cluster LOD 2c (#749): tolerance controller, per-view error, pre-pass, core fixes (53861e0d9c)
    • Cluster LOD 1b (#745): review fixes -- restore streams, Hi-Z resize gate, bitset first (0a5cb2fdbc)
    • #736: crash-loop guard for risky render settings (7ca5e7604d)
    • #736: name worker threads for the OS; the Windows crash line names the faulting thread (0e194285c0)

    Other changes

    • Preferences: Cluster LOD (experimental) checkbox in Advanced Graphics (7f0491d552)
    • GPU cursor pick: requests span the pick ray (camera focus reaches the draw distance again) (33ad9b2b02)

    • Cluster LOD weld: hard ceiling 2M entries (one named constant) (3487ccd0bd)
    • Cluster LOD weld: capacity follows demand; overflow skips whole avatars (seam lines) (ffb3556fd2)
