v2.1.1 Hotfix Release

on GitHub

🛠 Hotfix Release

Fixed: immediate crash on login / entering the world introduced in v2.1.0

After release, a few users reported a new crash:

• crash immediately after loading into the world
• crash around login / character entry
• more common on some custom clients and Vulkan/DXVK setups

We isolated the issue through multiple test builds.

Root cause

The culprit was the new GlobalAlloc fast path introduced in v2.1.0.

Crash isolation results:

• Test C (GlobalAlloc disabled) → stable
• Test G (all risky recent hooks disabled) → stable
• Other tests still crashed while GlobalAlloc remained enabled

Conclusion:
GlobalAlloc/GlobalFree semantics are too fragile for a public build, especially across different client wrappers and rendering environments.

What changed in v2.1.1

• Disabled GlobalAlloc fast path
• Kept all other v2.1.0 optimizations active:
  • CriticalSection spin-first path
  • SetFilePointer → SetFilePointerEx redirect
  • CompareStringA fast ASCII path
  • GetFileAttributesA cache
  • all previous allocator, GC, timer, I/O, and network optimizations

If you were affected

If v2.1.0 crashed:

• on login
• on entering the world
• shortly after loading in

please test v2.1.1.

Notes

This hotfix does not re-enable any previously removed unsafe public features:

• UI widget cache remains disabled
• GetSpellInfo cache remains disabled
