[image: fallback.png] PyCon Estonia 2023 is coming again! I am writing to invite you to submit a proposal for PyCon Estonia 2023, the annual conference to promote and educate people about the Python programming language. We aim to have our biggest, most international and diverse conference to date, and we believe your expertise and experience would be valuable to our program. The PyCon 2023 conference will take place on the *7th and 8th of September* at Tallinn University, and all speakers are expected to present their topics in person. We are currently accepting proposals for talks, workshops and lightning talks until the deadline on *21st April 2023*. All talks will be in English, and we welcome speakers of all experience levels and backgrounds to contribute. As a speaker, your talk and your slides must follow our Code of Conduct, ensuring that all content is appropriate for a professional audience. We have different types of talks available to choose from, including keynote talks, regular talks, lightning talks and workshops. You can find more information about each type of talk in the guidelines section of our call for papers <https://pyconestonia.typeform.com/to/hBOEtTQ3?typeform-source=pycon.ee>. We want the focus of the conference to be around the Python ecosystem, however, we are still welcoming talks on other relevant topics, such as Python challenges, outstanding packages, security, automation, AI/ML, web development, IoT, mental health for developers, and conducive work environment for coding. Speakers do not have to purchase a ticket and get free access to the whole conference. If you have bought a ticket in advance before being accepted, we will refund it.

PyCA cryptography 40.0.1 released
by Paul Kehrer 25 Mar '23

25 Mar '23

PyCA cryptography 40.0.1 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, X509, key derivation functions, and much more. We support Python 3.6+, and PyPy3 7.3.10+. Changelog (https://cryptography.io/en/latest/changelog/#v40-0-1): * Fixed a bug where certain operations would fail if an object happened to be in the top-half of the memory-space. This only impacted 32-bit systems. -Paul Kehrer (reaperhulk)

PyCA cryptography 40.0.0 released
by Paul Kehrer 23 Mar '23

23 Mar '23

PyCA cryptography 40.0.0 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, X509, key derivation functions, and much more. We support Python 3.6+, and PyPy3 7.3.10+. Changelog (https://cryptography.io/en/latest/changelog/#v40-0-0): * BACKWARDS INCOMPATIBLE: As announced in the 39.0.0 changelog, the way cryptography links OpenSSL has changed. This only impacts users who build cryptography from source (i.e., not from a wheel), and specify their own version of OpenSSL. For those users, the CFLAGS, LDFLAGS, INCLUDE, LIB, and CRYPTOGRAPHY_SUPPRESS_LINK_FLAGS environment variables are no longer valid. Instead, users need to configure their builds as documented here. * Support for Python 3.6 is deprecated and will be removed in the next release. * Deprecated the current minimum supported Rust version (MSRV) of 1.48.0. In the next release we will raise MSRV to 1.56.0. Users with the latest pip will typically get a wheel and not need Rust installed, but check Installation for documentation on installing a newer rustc if required. * Deprecated support for OpenSSL less than 1.1.1d. The next release of cryptography will drop support for older versions. * Deprecated support for DSA keys in load_ssh_public_key() and load_ssh_private_key(). * Deprecated support for OpenSSH serialization in DSAPublicKey and DSAPrivateKey. * The minimum supported version of PyPy3 is now 7.3.10. * Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.1.0. * Added support for parsing SSH certificates in addition to public keys with load_ssh_public_identity(). load_ssh_public_key() continues to support only public keys. * Added support for generating SSH certificates with SSHCertificateBuilder. * Added verify_directly_issued_by() to Certificate. * Added a check to NameConstraints to ensure that DNSName constraints do not contain any * wildcards. * Removed many unused CFFI OpenSSL bindings. This will not impact you unless you are using cryptography to directly invoke OpenSSL’s C API. Note that these have never been considered a stable, supported, public API by cryptography, this note is included as a courtesy. * The X.509 builder classes now raise UnsupportedAlgorithm instead of ValueError if an unsupported hash algorithm is passed. * Added public union type aliases for type hinting: Asymmetric types: PublicKeyTypes, PrivateKeyTypes, CertificatePublicKeyTypes, CertificateIssuerPublicKeyTypes, CertificateIssuerPrivateKeyTypes SSH keys: SSHPublicKeyTypes, SSHPrivateKeyTypes, SSHCertPublicKeyTypes, SSHCertPrivateKeyTypes PKCS12: PKCS12PrivateKeyTypes PKCS7: PKCS7HashTypes, PKCS7PrivateKeyTypes Two-factor: HOTPHashTypes * Deprecated previously undocumented but not private type aliases in the cryptography.hazmat.primitives.asymmetric.types module in favor of new ones above. -Paul Kehrer (reaperhulk)

unittest_expander 0.4.4 released
by Jan Kaliszewski 21 Mar '23

21 Mar '23

Dear Pythonistas, I am pleased to announce the release of unittest_expander 0.4.4. The changelog is available at: https://unittest-expander.readthedocs.io/en/stable/changes.html *** *unittest_expander* is a MIT-licensed Python library that provides flexible and easy-to-use tools to parameterize your unit tests, especially those based on `unittest.TestCase`. The library is compatible with Python 3.11, 3.10, 3.9, 3.8, 3.7, 3.6 and 2.7, and does not depend on any external packages (uses only the Python standard library). Simple usage example: ``` import unittest from unittest_expander import expand, foreach, param @expand class TestSomething(unittest.TestCase): @foreach( 'Foo', ('Foo', 43), param('Foo', spam=44), param(foo='Bar', spam=45).label('with bar'), empty=param(foo='', spam=46), ) def test_it(self, foo, spam=42, label=None): assert foo in ('Foo', 'Bar', '') assert 42 <= spam <= 46 if label == 'with bar': assert foo == 'Bar' and spam == 45 if label == 'empty': assert foo == '' and spam == 46 ``` This is only a fraction of the possibilities the unittest_expander library provides.

SCons 4.5.2 Released
by Bill Deegan 21 Mar '23

21 Mar '23

A new SCons release, 4.5.2, is now available on the SCons download page: https://scons.org/pages/download.html Here is a summary of the changes since 4.5.1: FIXES ----- - Fix a problem (#4321) in 4.5.0/4.5.1 where ParseConfig could cause an exception in MergeFlags when the result would be to add preprocessor defines to existing CPPDEFINES. The following code illustrates the circumstances that could trigger this: env=Environment(CPPDEFINES=['a']) env.Append(CPPDEFINES=['b']) env.MergeFlags({'CPPDEFINES': 'c'}) PACKAGING --------- - Remove the redundant `wheel` dependency from `pyproject.toml`, as it is added automatically by the setuptools PEP517 backend. Thanks to the following contributors listed below for their contributions to this release. ========================================================================================== .. code-block:: text git shortlog --no-merges -ns 4.5.1..HEAD 3 Mats Wichmann 2 William Deegan 1 Michał Górny
