I'm still a little iffy on how much of my own effort I can contribute to keep supporting this, but like most OSS projects: PRs welcome. ;)
Quick hits:
- GH actions are setup to do automated Linux and Windows builds of the extension: https://github.com/voided/CollisionHook/releases
- A few of the community fixes (such as the memory leak issue and a few others) have been included in this repo.
- Both x86 and x64 builds are available for TF2.
