The dominant story today is performance. Four separate pull requests trace back to a single July 16th performance analysis, and together they attack the same problem from different angles: garbage collection pressure and frame time.
Start with PR 368, pooling geometry buffers in the chunk mesher. This was identified as the top contributor to a measured 25 garbage collections per second during a desktop walk test — now those buffers are rented and reused instead of freshly allocated on every chunk build. PR 365 attacks the same symptom from the…
Second theme: two production-facing bugs, both fixed and shipped fast. PR 364 closes a real gap where hosted worlds were never forwarding crash reports — the crash-report key just wasn't in the container's environment list, so fleet crashes sat in local queues forever. And PR 347 fixed a login problem on…
