Version 3.5.2

3.5.2 (2026-09-29)

Changed

• Raised the Cython upper bound to <3.4 for native builds. The bound remains <3.3 for
  abi3 builds to preserve compatibility with the Python 3.7 Limited API.

Fixed

• Valid UTF-8 Chinese JSON incorrectly detected as PTCP154 due to excessive noise penalties
  for uncommon CJK characters. (#796)
• Supported encodings without aliases failing name resolution or being ignored in charset
  declarations. (#800)
