new Python Package Index is now in beta at pypi.org
by Sumana Harihareswara March 31, 2018

March 31, 2018

The new Python Package Index at https://pypi.org is now in beta. This means the site is robust, but we anticipate needing more user testing and changes before it is "production-ready" and can fully replace https://pypi.python.org . We hope to complete the transition before the end of April 2018. We're still working to ensure the new codebase and infrastructure are reliable. So please don't rely on it (yet) unless you can handle the occasional minor outage. But we want you to try the new PyPI, test it, and tell us if you have any problems. More at https://pyfound.blogspot.com/2018/03/warehouse-all-new-pypi-is-now-in-beta.… . For future announcements about PyPI, please subscribe to the low-traffic pypi-announce mailing list https://mail.python.org/mm3/mailman3/lists/pypi-announce.python.org/ . Thank you. -Sumana Harihareswara on behalf of the PyPI Team

Beta release of pip version 10
by Paul Moore March 31, 2018

March 31, 2018

On behalf of the PyPA, I am pleased to announce that a beta release 10.0.0b1 of pip has just been released for testing by the community. We're planning on a final release in 2 weeks' time, over the weekend of 14/15 April. To install pip 10.0.0.b1, you can run python -m pip install --upgrade --pre pip (obviously, you should not do this in a production environment!) We would be grateful for all testing that users could do, to ensure that when pip 10 is released it's as solid as we can make it. Highlights of the new release: * Python 2.6 is no longer supported - if you need pip on Python 2.6, you should stay on pip 9, which is the last version to support Python 2.6. * Support for PEP 518, which allows projects to specify what packages they require in order to build from source. (PEP 518 support is currently limited, with full support coming in future versions - see the documentation for details). * Significant improvements in Unicode handling for non-ASCII locales on Windows. * A new "pip config" command. * The default upgrade strategy has become "only-if-needed" * Many bug fixes and minor improvements. In addition, the previously announced reorganisation of pip's internals has now taken place. Unless you are the author of code that imports the pip module (or a user of such code), this change will not affect you. If you are, please report the issue to the author of the affected code (refer them to https://mail.python.org/pipermail/distutils-sig/2017-October/031642.html for the details of the announcement). Please note that there is a minor issue with the NEWS file for this release - the new features in 10.0.0b1 are reported as being for "9.0.3 (2018-03-31)". If you discover any bugs while testing the new release, please report them at https://github.com/pypa/pip/issues. Thanks to everyone who put so much effort into the new release. Many of the contributions came from community members, whether in the form of code, participation in design discussions, or bug reports. The pip development team is extremely grateful to everyone in the community for their contributions. Thanks, Paul

[RELEASE] Python 3.7.0b3 is now available for testing
by Ned Deily March 30, 2018

March 30, 2018

On behalf of the Python development community and the Python 3.7 release team, I'm happy to announce the availability of Python 3.7.0b3. b3 is the third of four planned beta releases of Python 3.7, the next major release of Python, and marks the end of the feature development phase for 3.7. You can find Python 3.7.0b3 here: https://www.python.org/downloads/release/python-370b3/ Among the new major new features in Python 3.7 are: * PEP 538, Coercing the legacy C locale to a UTF-8 based locale * PEP 539, A New C-API for Thread-Local Storage in CPython * PEP 540, UTF-8 mode * PEP 552, Deterministic pyc * PEP 553, Built-in breakpoint() * PEP 557, Data Classes * PEP 560, Core support for typing module and generic types * PEP 562, Module __getattr__ and __dir__ * PEP 563, Postponed Evaluation of Annotations * PEP 564, Time functions with nanosecond resolution * PEP 565, Show DeprecationWarning in __main__ * PEP 567, Context Variables Please see "What’s New In Python 3.7" for more information. Additional documentation for these features and for other changes will be provided during the beta phase. https://docs.python.org/3.7/whatsnew/3.7.html Beta releases are intended to give you the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release. We strongly encourage you to test your projects with 3.7 during the beta phase and report issues found to https://bugs.python.org as soon as possible. While the release is feature complete entering the beta phase, it is possible that features may be modified or, in rare cases, deleted up until the start of the release candidate phase (2018-05-21). Our goal is have no ABI changes after beta 3 and no code changes after rc1. To achieve that, it will be extremely important to get as much exposure for 3.7 as possible during the beta phase. Attention macOS users: there is a new installer variant for macOS 10.9+ that includes a built-in version of Tcl/Tk 8.6. This variant is expected to become the default version when 3.7.0 releases. Check it out! We welcome your feedback. As of 3.7.0b3, the legacy 10.6+ installer also includes a built-in Tcl/Tk 8.6. Please keep in mind that this is a preview release and its use is not recommended for production environments. The next planned release of Python 3.7 will be 3.7.0b4, currently scheduled for 2018-04-30. More information about the release schedule can be found here: https://www.python.org/dev/peps/pep-0537/ -- Ned Deily nad(a)python.org -- []

ANN: A new version (0.4.2) of python-gnupg has been released.
by Vinay Sajip March 28, 2018

March 28, 2018

A new version of the Python module which wraps GnuPG has been released. What Changed? ============= This is an enhancement and bug-fix release, and all users are encouraged to upgrade. See the project website [1] for more information. Brief summary: * Subkey information is now collected and returned in a subkey_info dictionary keyed by the subkey's ID. * GPG2 version is now correctly detected on OS X. * Added expect_passphrase keyword argument for use on GnuPG >= 2.1 when passing passphrase to gpg via pinentry. * Provided a trust_keys method to allow setting the trust level for keys. Thanks to William Foster for a suggested implementation. * Made the exception message when the gpg executable is not found contain the path of the executable that was tried. Thanks to Kostis Anagnostopoulos for the suggestion. * Made the error message less categorical in the case of a failure with an unspecified reason, adding some information from gpg error codes when available. This release [2] has been signed with my code signing key: Vinay Sajip (CODE SIGNING KEY) <vina... at yahoo.co.uk> Fingerprint: CA74 9061 914E AC13 8E66 EADB 9147 B477 339A 9B86 What Does It Do? ================ The gnupg module allows Python programs to make use of the functionality provided by the Gnu Privacy Guard (abbreviated GPG or GnuPG). Using this module, Python programs can encrypt and decrypt data, digitally sign documents and verify digital signatures, manage (generate, list and delete) encryption keys, using proven Public Key Infrastructure (PKI) encryption technology based on OpenPGP. This module is expected to be used with Python versions >= 2.4, as it makes use of the subprocess module which appeared in that version of Python. This module is a newer version derived from earlier work by Andrew Kuchling, Richard Jones and Steve Traugott. A test suite using unittest is included with the source distribution. Simple usage: >>> import gnupg >>> gpg = gnupg.GPG(gnupghome='/path/to/keyring/directory') >>> gpg.list_keys() [{ ... 'fingerprint': 'F819EE7705497D73E3CCEE65197D5DAC68F1AAB2', 'keyid': '197D5DAC68F1AAB2', 'length': '1024', 'type': 'pub', 'uids': ['', 'Gary Gross (A test user) <gary.gr... at gamma.com>']}, { ... 'fingerprint': '37F24DD4B918CC264D4F31D60C5FEFA7A921FC4A', 'keyid': '0C5FEFA7A921FC4A', 'length': '1024', ... 'uids': ['', 'Danny Davis (A test user) <danny.da... at delta.com>']}] >>> encrypted = gpg.encrypt("Hello, world!", ['0C5FEFA7A921FC4A']) >>> str(encrypted) '-----BEGIN PGP MESSAGE-----\nVersion: GnuPG v1.4.9 (GNU/Linux)\n \nhQIOA/6NHMDTXUwcEAf . -----END PGP MESSAGE-----\n' >>> decrypted = gpg.decrypt(str(encrypted), passphrase='secret') >>> str(decrypted) 'Hello, world!' >>> signed = gpg.sign("Goodbye, world!", passphrase='secret') >>> verified = gpg.verify(str(signed)) >>> print "Verified" if verified else "Not verified" 'Verified' As always, your feedback is most welcome (especially bug reports [3], patches and suggestions for improvement, or any other points via the mailing list/discussion group [4]). Please refer to the documentation [5] for more information. Enjoy! Cheers Vinay Sajip Red Dove Consultants Ltd.

Release of fades 7.0
by Facundo Batista March 26, 2018

March 26, 2018

Hello all, We're glad to announce the release of fades 7. fades is a system that automatically handles the virtualenvs in the cases normally found when writing scripts and simple programs, and even helps to administer big projects. It will automagically create a new virtualenv (or reuse a previous created one), installing the necessary dependencies, and execute your script inside that virtualenv. You only need to execute the script with fades (instead of Python) and also mark the required dependencies. More details here: http://fades.rtfd.org/ What's new in this release? - Pre-check if everything requested is really available in PyPI before starting to install them - Ignore duplicated dependencies - Several enhancements and fixes in the messages fades shows in verbose mode - Forbid fades misusing: installing it with legacy Python and running it from inside another virtualenv - Lot of project related improvements (not visible directly to final user, though) and some small bug fixes Nicolás and I want to say a big thank you to the following collaborators that helped to improve and enhance fades in different ways for this version (in alphabetical order): Evan - https://github.com/evandandrea Juan Carlos - https://github.com/juancarlospaco Rotem Yaari - https://github.com/vmalloc To install and enjoy fades... - If you are in Ubuntu or Debian, you can easily install like this (but probably won't get *latest* fades: sudo apt-get install fades - For not latest debian/ubuntu you have a .deb here (with checksum and signature): http://taniquetil.com.ar/fades/fades-latest.deb http://taniquetil.com.ar/fades/fades-latest.deb.sha1 http://taniquetil.com.ar/fades/fades-latest.deb.asc - Install it in Arch is very simple: yaourt -S fades - In any Linux if you have the Snap system: snap install fades - Using pip if you want: pip3 install fades - You can always get the multiplatform tarball and install it in the old fashion way: wget http://taniquetil.com.ar/fades/fades-latest.tar.gz tar -xf fades-latest.tar.gz cd fades-* sudo ./setup.py install Also have the checksum and signature, if interested: http://taniquetil.com.ar/fades/fades-latest.tar.gz.sha1 http://taniquetil.com.ar/fades/fades-latest.tar.gz.asc Help / questions: - You can ask any question or send any recommendation or request in the Telegram group: https://t.me/fadesmagic ...or to the mailing list... http://listas.python.org.ar/mailman/listinfo/fades ...or in the #fades IRC channel (in Freenode). - Also, you can open an issue here (please do if you find any problem!). https://github.com/PyAr/fades/issues/new - The project itself is in https://github.com/PyAr/fades It's very easy to run latest development version: git clone https://github.com/PyAr/fades.git cd fades bin/fades Thanks in advance for your time! -- .
