What's new in CheetahTemplate3 ============================== Nothing changed in the library code, no need to upgrade. Tests: - Run tests with Python 3.11. - Fix DeprecationWarning: ``unittest.findTestCases()`` is deprecated. Use ``unittest.TestLoader.loadTestsFromModule()`` instead. CI: - Publish wheels at Github Releases. What is CheetahTemplate3 ======================== Cheetah3 is a free and open source (MIT) Python template engine. It's a fork of the original CheetahTemplate library. Python 2.7 or 3.4+ is required.

structlog 22.2.0
by Hynek Schlawack 19 Nov '22

19 Nov '22

I’m happy to announce a new release of structlog! With more than 4 million downloads per month, structlog is the best solution for production-ready structured logging in Python. It doesn’t just allow you to log key-value pairs in a structured manner, it also makes it EASIER and FASTER. Check out <https://www.structlog.org/en/stable/why.html> if you’re intrigued but not convinced! --- This is another (too) big release, but before I go into new features, allow me to beg you to check out structlog's documentation: <https://www.structlog.org/>. I've spent easily half of the time on bringing is up to date, restructuring, and adding usage recipes. Not new in this release, but did you know that the standard library chapter has flowcharts that give you as visual explanations of how the various methods work? This is usually the biggest sticking point when starting to use structlog. Feature-wise the big thing is that structlog's internal (and extremely fast) loggers (the one created using structlog.make_filtering_bound_logger() got two new features that people have asked for forever: 1. String interpolation: log.info("hello %s!", "world") works now! 2. Async! Each logging method has an async version: await log.ainfo("hello %s!", "world") is the same thing as above, but async. Special Thanks This release would not be possible without my generous sponsors! Thank you to all of you making sustainable maintenance possible! If you would like to join them, go to https://github.com/sponsors/hynek and check out the sweet perks! Above and Beyond Variomedia AG (@variomedia), Tidelift (@tidelift), Sentry (@getsentry), HiredScore (@HiredScore), FilePreviews (@filepreviews), and Daniel Fortunov (@asqui). Maintenance Sustainers @rzijp, Adam Hill (@adamghill), Dan Groshev (@si14), Tamir Bahar (@tmr232), Adi Roiban (@adiroiban), Magnus Watn (@magnuswatn), David Cramer (@dcramer), Moving Content AG (@moving-content), Stein Magnus Jodal (@jodal), Iwan Aucamp (@aucampia), ProteinQure (@ProteinQure), Jesse Snyder (@jessesnyder), Rivo Laks (@rivol), Thomas Ballinger (@thomasballinger), @medecau, Ionel Cristian Mărieș (@ionelmc), The Westervelt Company (@westerveltco), Philippe Galvan (@PhilippeGalvan), Birk Jernström (@birkjernstrom), Jannis Leidel (@jezdez), Tim Schilling (@tim-schilling), Chris Withers (@cjw296), and Christopher Dignam (@chdsbd). Not to forget 2 more amazing humans who chose to be generous but anonymous! Full Changelog Deprecated - Accessing package metadata as attributes on the structlog module is deprecated (e.g. structlog.__version__). Please use importlib.metadata instead (for Python 3.7: the importlib-metadata PyPI package). - The structlog.types module is now deprecated in favor of the structlog.typing module. It seems like the Python typing community is settling on this name. Added - FilteringBoundLogger (used by default) now allows for string interpolation using positional arguments: >>> log.info("Hello %s! The answer is %d.", "World", 42, x=1) 2022-10-07 10:04.31 [info ] Hello World! The answer is 42. x=1 #454 - FilteringBoundLogger now also has support for asyncio-based logging. Instead of a wrapper class like structlog.stdlib.AsyncBoundLogger, async equivalents have been added for all logging methods. So instead of log.info("hello") you can also write await log.ainfo("hello") in async functions and methods. This seems like the better approach and if it's liked by the community, structlog.stdlib.BoundLogger will get those methods too. #457 Changed - The documentation has been heavily overhauled. Have a look if you haven't lately! Especially the graphs in the standard library chapter have proven valuable to many. - The build backend has been switched to Hatch. Fixed - The timestamps in the default configuration now use the correct separator (:) for seconds.

Python 3.12.0 alpha 2 released
by Thomas Wouters 15 Nov '22

15 Nov '22

I'm pleased to announce the release of Python 3.12 alpha 2. https://www.python.org/downloads/release/python-3120a2/ *This is an early developer preview of Python 3.12*. Major new features of the 3.12 series, compared to 3.11 Python 3.12 is still in development. This release, 3.12.0a2 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 (2023-05-08) and, if necessary, may be modified or deleted up until the release candidate phase (2023-07-31). Please keep in mind that this is a preview release and its use is **not** recommended for production environments. Many new features for Python 3.12 are still being planned and written. Among the new major new features and changes so far: - Even more improved error messages. More exceptions potentially caused by typos now make suggestions to the user. - Support for the Linux perf profiler to report Python function names in traces. - The deprecated wstr and wstr_length members of the C implementation of unicode objects were removed, per PEP 623 <https://peps.python.org/pep-0623>. - In the unittest module, a number of long deprecated methods and classes were removed. (They had been deprecated since Python 3.1 or 3.2). - The deprecated smtpd and distutils modules have been removed (see PEP 594 <https://peps.python.org/pep-0594/> and PEP 632 <https://peps.python.org/pep-0632/>). The setuptools package (installed by default in virtualenvs and many other places) continues to provide the distutils module. - A number of other old, broken and deprecated functions, classes and methods have been removed. - (Hey, **fellow core developer,** if a feature you find important is missing from this list, let Thomas know <thomas(a)python.org>.) For more details on the changes to Python 3.12, see What's new in Python 3.12 <https://docs.python.org/dev/whatsnew/3.12.html>. The next pre-release of Python 3.12 will be 3.12.0a3, currently scheduled for 2022-12-05. More resources Online Documentation <https://docs.python.org/3.12/>.

Charlotte wrote about the publishing under pseudonyms by her and her sisters, Emily and Anne, in a preface to Emily's *Wuthering Heights*: Averse to personal publicity, we veiled our own names under those of > Currer, Ellis and Acton Bell; the ambiguous choice being dictated by a sort > of conscientious scruple at assuming Christian names positively masculine, > while we did not like to declare ourselves women, because – without at > that time suspecting that our mode of writing and thinking was not what is > called "feminine" – we had a vague impression that authoresses are liable > to be looked on with prejudice; we had noticed how critics sometimes use > for their chastisement the weapon of personality, and for their reward, a > flattery, which is not true praise.
