v2026.6.4

What's New in v2026.6.4

A stability fix release on top of v2026.6.3.

• Multithreaded GC stability fix — fixed an intermittent crash (0xC0000005) in the generational minor garbage collector during thread startup. A thread being spawned held its self and argument as untracked raw pointers, so a moving collection during the spawn handoff could relocate the still-live object and leave the new thread a stale reference. These are now tracked and relocated across collection. Surfaced only under heavy multithreaded churn.
