  CVE-2025-69277.

v1.6.1

Compare Source

• The MAKE environment variable can now be used to specify the make
  binary that should be used in the build process.

v1.6.0

Compare Source

• BACKWARDS INCOMPATIBLE: Removed support for Python 3.6 and 3.7.
• Added support for the low level AEAD AES bindings.
• Added support for crypto_core_ed25519_from_uniform.
• Update libsodium to 1.0.20-stable (2025-08-27 build).
• Added support for free-threaded Python 3.14.
• Added support for Windows on ARM wheels.

v1.5.0

Compare Source

• BACKWARDS INCOMPATIBLE: Removed support for Python 2.7 and Python 3.5.
• BACKWARDS INCOMPATIBLE: We no longer distribute manylinux1
  wheels.
• Added manylinux2014, manylinux_2_24, musllinux, and macOS
  universal2 wheels (the latter supports macOS arm64).
• Update libsodium to 1.0.18-stable (July 25, 2021 release).
• Add inline type hints.

v1.4.0

Compare Source

• Update libsodium to 1.0.18.
• BACKWARDS INCOMPATIBLE: We no longer distribute 32-bit manylinux1
  wheels. Continuing to produce them was a maintenance burden.
• Added support for Python 3.8, and removed support for Python 3.4.
• Add low level bindings for extracting the seed and the public key
  from crypto_sign_ed25519 secret key
• Add low level bindings for deterministic random generation.
• Add wheel and setuptools setup_requirements in setup.py (#​485)
• Fix checks on very slow builders (#​481, #​495)
• Add low-level bindings to ed25519 arithmetic functions
• Update low-level blake2b state implementation
• Fix wrong short-input behavior of SealedBox.decrypt() (#​517)
• Raise CryptPrefixError exception instead of InvalidkeyError when trying
  to check a password against a verifier stored in a unknown format (#​519)
• Add support for minimal builds of libsodium. Trying to call functions
  not available in a minimal build will raise an UnavailableError
  exception. To compile a minimal build of the bundled libsodium, set
  the SODIUM_INSTALL_MINIMAL environment variable to any non-empty
  string (e.g. SODIUM_INSTALL_MINIMAL=1) for setup.
