Major Changes:

Note: The automatically created "Source Code" zip and tar.gz files are broken and can't be fixed (GitHub limitation regarding git submodules). If you need this, please download the attached zxing-cpp-<...>.zip/.tar.gz file.

New/Improved Symbologies

Added decoder support for Telepen symbology
Added decoder support for MicroPDF417 (sponsored by Allied Vision Konstanz GmbH)
Greatly improved Aztec detector for large, non-flat symbols by evaluating internal timing patterns
Greatly improved DataMatrix detector for large, non-flat symbols by evaluating internal alignment patterns
Major improvement in QRCode detection of many small symbols in a single image

New/Improved wrappers

Added a Go wrapper
Switched from pybind11 to nanobind in Python wrapper code (enhanced IDE support, faster build times, smaller binaries, free-threaded Python support)

General

Improved API documentation, now published under https://zxing-cpp.github.io/zxing-cpp/docs/latest
Considerable performance improvements, especially on ARM chips (10%-40% in specific scenarios)
ReedSolomon: generic implementation for prime and extended Galois Fields with improved performance
Added support for "Unused Error Correction" meta data (Barcode::extra("UEC"))
