How this number is computed

Composite = sum of sub_score × weight across six metrics. Sub-scores are percentile-rank(log1p(min(raw, p95))) within the beta cohort (77 releases). Sub-scores for lower-is-better metrics are flipped to 100 − percentile.

* = raw value was clipped at the cohort 95th percentile to prevent outliers from compressing everyone else's scores. Sub-scores marked "med" substitute the cohort median where the input was missing (e.g. first patch on a minor line has no prior patch for net-fix delta).

Fixed an issue where VideoClips referenced by Content Directory builds failed to load at runtime on macOS. (UUM-147430) First seen in 6000.6.0b3. Fixed in 6000.6.0f1.

Awaitable.NextFrameAsync now resumes in edit mode, including when the Editor runs in batch mode, instead of waiting indefinitely for an unrelated scene update. (UUM-148723) First seen in 6000.6.0b8. Fixed in 6000.6.0b10.
EditorKnown issueCautionUUM-148723
Fixed the Windows Editor failing to start when the Microsoft Visual C++ 2010 runtime is not installed; the CPU Progressive Lightmapper now reports that it is unavailable instead. (UUM-149122) Fixed in 6000.6.0b10.
GIKnown issueCautionWindowsUUM-149122
Fixed a predicted ghost divergence caused by running at very high framerates with very low SimulationTickRate, which meant that the client to not even fully predict one tick ahead of the latest snapshot arrival, causing the snapshot to be applied on a partial tick, which in turn resulted in the prediction-history backup failing to write, so it would constantly be stale. (UUM-147343) Fixed in 6000.6.0f1.
Netcode for EntitiesKnown issueCautionUUM-147343
Fixed UI failing to render on OpenGL ES and WebGL 2.0 devices when the UI shader exceeded the platform's vertex uniform limit. (UUM-149277) First seen in 6000.6.0b9. Fixed in 6000.6.0b10.
