Changelog: v2.5

v2.5.8 (2026-09-04)

• rayrai: mesh GPU buffers shared across GL contexts (no VRAM growth per render thread); windows created on a thread with a current context join its share group.
• RayraiGlobalAsset shared GPU-asset cache controls and sharedGpuAssetStats.
• Async RGB/depth readback uses the full PBO ring; fixed worker cameras sharing a depth texture.

v2.5.7 (2026-09-03)

• rayrai: no "ghost" objects when a removed object's address is reused (stable Object::Id); camera drops a removed target.
• Linux installer confirms before deleting old installs and retries with sudo.

v2.5.6 (2026-09-02)

• TCP viewer: per-camera frustum and frame toggles.
• "hidden"/"invisible" appearance removes an object from rendering.
• Fixed removed heightmaps in depth renders; protocol reader rejects oversized lengths.
• Faster contact-solver iterations and warm-start lookups.

v2.5.5 (2026-08-30)

• TCP viewer renders the server's MANUAL RGB/depth sensors and shows previews and frustums.
• Live Signals graphs, replay seek, network diagnostics; server-side record/screenshot/window-size commands.
• PROTOCOL_FEATURE_CONTACT_OBJECT_TAGS.
• Sensors keep updating while their system sleeps or is fixed.
• Depth rendering can include custom/instanced visuals.
• TCP viewer ships as example source; RAISIM_VISUALIZER_INSTALL removed.

v2.5.4 (2026-08-29)

• Heightmap contacts: wheels no longer sink or tunnel on steps, contacts match the triangulated surface, buried bodies recover smoothly.
• TCP viewer saves the user UI scale.
• No C++20 <bit> dependency; Mesh/World ABI guard.

v2.5.3 (2026-08-24)

• Faster heightmap–primitive (bit-identical) and heightmap–mesh contacts.
• Reproducible contacts across builds (-ffp-contract=on); CONFIGURE_DEPENDS globs; MSVC fix.

v2.5.2 (2026-08-22)

• Heightmap fixes: no false contacts above the surface or across seams, thin/tiny shapes near the boundary, buried primitives, large translations, stale contacts after updates.
• Clients can connect during a busy simulation; faster TCP viewer mesh batching.

v2.5.1 (2026-08-20)

• Fixed missed heightmap contacts with box edges and cylinder sides/caps.
• Faster large heightmaps in the TCP viewer; heightmap no longer sent twice.
• Visuals::notifyMeshMaterialsChanged.

v2.5.0 (2026-08-18)

• World::rayTest uses a lazily rebuilt BVH.
• World::rayTestLidar ~12.5× faster per ray (28 ns vs 355 ns).
• Breaking: rayTestLidar takes yaw/pitch start, increment and count.
