 > [!NOTE]
-> **Community Fork Notice:** This is a temporary fork of [`asg017/sqlite-vec`](https://github.com/asg017/sqlite-vec)
-> - Created to merge pending upstream PRs and provide community support while the original author is unavailable.
-> - Once development resumes on the original repository, users are encouraged to switch back.
-> - All credit for the original implementation goes to [Alex Garcia](https://github.com/asg017).
-> - Credit for creating the fork and merging PRs goes to [Vlad Lasky](https://github.com/vlasky).
-> 
-> This branch includes:
-> - Hardening (replaced atoi() with strtol(), vendor.sh SHA validation, pinned GHA versions, OIDC releases)
-> - Update to the latest SQLite release (should be no-op, and backward compatible)
-> - Node.js release added Alpine/MUSL x64/arm64 and Windows arm64 prebuilds
-> - Node.js package now includes all prebuilds (no post-install scripts!)
-
-> Feel free to cherry-pick any changes back upstream -- commits are kept small and isolated for this purpose.
