PyCA cryptography 44.0.0 released
by Paul Kehrer Nov. 27, 2024

Nov. 27, 2024

PyCA cryptography 44.0.0 has been released to PyPI. cryptography includes both high level recipes and low level interfaces to common cryptographic algorithms such as symmetric ciphers, asymmetric algorithms, message digests, X.509, key derivation functions, and much more. We support Python 3.7+, and PyPy3 7.3.10+. Changelog (https://cryptography.io/en/latest/changelog/#v44-0-0): * BACKWARDS INCOMPATIBLE: Dropped support for LibreSSL < 3.9. * Deprecated Python 3.7 support. Python 3.7 is no longer supported by the Python core team. Support for Python 3.7 will be removed in a future cryptography release. * Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.4.0. * macOS wheels are now built against the macOS 10.13 SDK. Users on older versions of macOS should upgrade, or they will need to build cryptography themselves. * Enforce the RFC 5280 requirement that extended key usage extensions must not be empty. * Added support for timestamp extraction to the MultiFernet class. * Relax the Authority Key Identifier requirements on root CA certificates during X.509 verification to allow fields permitted by RFC 5280 but forbidden by the CA/Browser BRs. * Added support for Argon2id when using OpenSSL 3.2.0+. * Added support for the Admissions certificate extension. * Added basic support for PKCS7 decryption (including S/MIME 3.2) via pkcs7_decrypt_der(), pkcs7_decrypt_pem(), and pkcs7_decrypt_smime(). -Paul Kehrer (reaperhulk)

[RELEASE] Python 3.14.0 alpha 2 is out
by Hugo van Kemenade Nov. 19, 2024

Nov. 19, 2024

Alpha 2? But Alpha 1 only just came out! https://www.python.org/downloads/release/python-3140a2/ This is an early developer preview of Python 3.14 Major new features of the 3.14 series, compared to 3.13: Python 3.14 is still in development. This release, 3.14.0a2 is the second of seven planned alpha releases. Alpha releases are intended to make it easier to test the current state of new features and bug fixes and to test the release process. During the alpha phase, features may be added up until the start of the beta phase (2025-05-06) and, if necessary, may be modified or deleted up until the release candidate phase (2025-07-22). Please keep in mind that this is a preview release and its use is not recommended for production environments. Many new features for Python 3.14 are still being planned and written. Among the new major new features and changes so far: * PEP 649: deferred evaluation of annotations * PEP 741: Python configuration C API * PEP 761: Python 3.14 and onwards no longer provides PGP signatures for release artifacts. Instead, Sigstore is recommended for verifiers. * Improved error messages * (Hey, fellow core developer, if a feature you find important is missing from this list, let Hugo know.) The next pre-release of Python 3.14 will be 3.14.0a3, currently scheduled for 2024-12-17. More resources * Online documentation: https://docs.python.org/3.14/ * PEP 745, 3.14 Release Schedule: https://peps.python.org/pep-0719/ * Report bugs at https://github.com/python/cpython/issues * Help fund Python and its community: https://www.python.org/psf/donations/ And now for something completely different Ludolph van Ceulen (1540-1610) was a fencing and mathematics teacher in Leiden, Netherlands, and spent around 25 years calculating π (or pi), using essentially the same methods Archimedes employed some seventeen hundred years earlier. Archimedes estimated π by calculating the circumferences of polygons that fit just inside and outside of a circle, reasoning the circumference of the circle lies between these two values. Archimedes went up to polygons with 96 sides, for a value between 3.1408 and 3.1428, which is accurate to two decimal places. Van Ceulen used a polygon with half a billion sides. He published a 20-decimal value in his 1596 book Vanden Circkel (“On the Circle”), and later expanded it to 35 decimals: 3.14159265358979323846264338327950288 Van Ceulen’s 20 digits is more than enough precision for any conceivable practical purpose. For example, even if a printed circle was perfect down to the atomic scale, the thermal vibrations of the molecules of ink would make most of those digits physically meaningless. NASA Jet Propulsion Laboratory’s highest accuracy calculations, for interplanetary navigation, uses 15 decimals: 3.141592653589793. At Van Ceulen’s request, his upper and lower bounds for π were engraved on his tombstone in Leiden. The tombstone was eventually lost but restored in 2000. In the Netherlands and Germany, π is sometimes referred to as the “Ludolphine number”, after Van Ceulen. Enjoy the new release Thanks to all of the many volunteers who help make Python Development and these releases possible! Please consider supporting our efforts by volunteering yourself or through organisation contributions to the Python Software Foundation.

logassert v8 released!
by Facundo Batista Nov. 8, 2024

Nov. 8, 2024

The version 8 of `logassert` brings support for the structlog library. Yes, now you can use the whole power of logassert when using structlog as a logger. There are also small administrative enhancements: better README (and documentation in [Read The Docs]()), the CI uses modern Pythons, better tested badge, etc. What is logassert? A simple log assertion mechanism for Python unittests. Provides a simple and expressive way to use it in the unit tests and when the assertion fails it presents a useful report that helps you to find out why it is failing. Includes a fixture to use it with `pytest` and can also be used in classic unit tests. Allows checking using regular expressions, exact strings, multiple strings, and even sequences of several lines, including support for verifying that nothing was logged, and of course filtering by the log level (if desired).
