Build fixes, typo fixes, fixed some internal int -> size_t. (Which will change the size of objects, but not the API.)
Fix CVE-2024-50615 which was a problem parsing character encodings.
NOTE: this actually has a minor breaking API change in the return size of strings. (Of course, if that causes a bug / stack corruption in your use case, perhaps not so minor.) 11.0.0 is the same as this release, but correctly versioned.
