Unity Transport: Network interfaces are now automatically disposed of before domain reloads. Without this protection, socket handles could be leaked which would cause errors when trying to re-bind to the same port later on. Note that this isn't a replacement for properly disposing of NetworkDriver objects; it's only a protection in cases where that's not done.

Retrieved 2026-11-09Fixed 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.
Fixed a regression in the handling of partial sends. In rare cases, the same dynamic ghost chunk hits the partial boundary at roughly the same entity index every tick. This indefinitely causes a subset of its ghosts to no longer be added to the snapshot.
Fixed a spurious "JobTempAlloc has allocations that are more than the maximum lifespan of 4 frames old" warning that appeared when baking a ghost prefab set to Owner Predicted mode without a GhostOwner component.
Netcode for EntitiesFix

When loading, unloading and reloading the subscenes the ghost collection prefab would point to a previously unloaded/deleted entity prefab.
