Version 8.0.0

Major changes

The major change in this release is that now most simdutf functions are immediate functions (constexpr), i.e., they can be executed at compile time. Thus, for example, you can validate that a string is proper UTF-8 at compile time:

static_assert(simdutf::validate_utf8(s));

The constexpr interface requires C++23. (You can still use simdutf with C++11.)

Another major change is the introduction of a C API. You can now easily call simdutf from C (although you still need to link against a C++ library, either statically or at runtime). This C API should make it easier to write wrappers to simdutf from other programming languages. We now include a C header as part of our releases.

What's Changed

• make most of simdutf constexpr
• add C API
• fix bug in utf8_length_from_utf16() on big endian
• interop with std::text_encoding
• polish the functions in encoding_types.h
• ensure the override keyword is used everywhere
• Fix heap-buffer-overflow in convert_utf16_to_utf8_safe
• fixing issue 914 (convert_latin1_to_utf8_safe is missing from the C api)
• Fix typos
• Update/optimize Loongson kernels

Because we fixed a couple of bugs, including a potential buffer overflow in convert_utf16_to_utf8_safe, we recommend that all users of the library update to 8.0.0. There are no breaking changes.

Infrastructure changes

• oss-fuzz: Add unit testing build in oss-fuzz build script
• fixes the check_feature_macros script.
• add ci job for checking typos
• add fuzzer for convert_*_safe() functions
• strengthen the safe_conversion fuzzer
