[RELEASE] Python 3.13.0 beta 3 released.
by Thomas Wouters June 27, 2024

June 27, 2024

The *next to last* Python 3.13 beta version, beta 3, is now released: https://www.python.org/downloads/release/python-3130b3/ *This is a beta preview of Python 3.13* Python 3.13 is still in development. This release, 3.13.0b3, is the third of four beta release previews of 3.13. Beta release previews are intended to give the wider community the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release. We *strongly encourage* maintainers of third-party Python projects to *test with 3.13* during the beta phase and report issues found to the Python bug tracker <https://github.com/python/cpython/issues> as soon as possible. While the release is planned to be 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 (Tuesday 2024-07-30). Our goal is to have no ABI changes after beta 4 and as few code changes as possible after 3.13.0rc1, the first release candidate. To achieve that, it will be *extremely important* to get as much exposure for 3.13 as possible during the beta phase. Please keep in mind that this is a preview release and its use is *not* recommended for production environments. <https://discuss.python.org/t/python-3-13-0-beta-3-now-available/56847#major…>Major new features of the 3.13 series, compared to 3.12 Some of the new major new features and changes in Python 3.13 are: <https://discuss.python.org/t/python-3-13-0-beta-3-now-available/56847#new-f…>New features - A new and improved interactive interpreter <https://docs.python.org/3.13/whatsnew/3.13.html#a-better-interactive-interp…>, based on PyPy <https://pypy.org>’s, featuring multi-line editing and color support, as well as colorized exception tracebacks <https://docs.python.org/3.13/whatsnew/3.13.html#improved-error-messages> . - An *experimental* free-threaded build mode <https://docs.python.org/3.13/whatsnew/3.13.html#free-threaded-cpython>, which disables the Global Interpreter Lock, allowing threads to run more concurrently. The build mode is available as an experimental feature in the Windows and macOS installers as well. - A preliminary, *experimental* JIT <https://docs.python.org/3.13/whatsnew/3.13.html#experimental-jit-compiler>, providing the ground work for significant performance improvements. - The (cyclic) garbage collector is now incremental <https://docs.python.org/3.13/whatsnew/3.13.html#incremental-garbage-collect…>, which should mean shorter pauses for collection in programs with a lot of objects. - A modified version of mimalloc <https://github.com/microsoft/mimalloc> is now included, optional but enabled by default if supported by the platform, and required for the free-threaded build mode. - Docstrings now have their leading indentation stripped <https://docs.python.org/3.13/whatsnew/3.13.html#other-language-changes>, reducing memory use and the size of .pyc files. (Most tools handling docstrings already strip leading indentation.) - The dbm module <https://docs.python.org/3.13/library/dbm.html> has a new dbm.sqlite3 backend <https://docs.python.org/3.13/whatsnew/3.13.html#dbm> that is used by default when creating new files. - The minimum supported macOS version was changed from 10.9 to *10.13 (High Sierra)*. Older macOS versions will not be supported going forward. <https://discuss.python.org/t/python-3-13-0-beta-3-now-available/56847#typin…> Typing - Support for type defaults in type parameters <https://peps.python.org/pep-0696/>. - A new type narrowing annotation <https://peps.python.org/pep-0742/>, typing.TypeIs. - A new annotation for read-only items in TypeDicts <https://peps.python.org/pep-0705/>. <https://discuss.python.org/t/python-3-13-0-beta-3-now-available/56847#remov…>Removals and new deprecations - PEP 594 (Removing dead batteries from the standard library) <https://peps.python.org/pep-0594/> scheduled removals of many deprecated modules: aifc, audioop, chunk, cgi, cgitb, crypt, imghdr, mailcap, msilib, nis, nntplib, ossaudiodev, pipes, sndhdr, spwd, sunau, telnetlib, uu, xdrlib, lib2to3. - Many other removals <https://docs.python.org/3.13/whatsnew/3.13.html#removed> of deprecated classes, functions and methods in various standard library modules. - C API removals <https://docs.python.org/3.13/whatsnew/3.13.html#id10> and deprecations <https://docs.python.org/3.13/whatsnew/3.13.html#id9>. (Some removals present in alpha 1 were reverted in alpha 2, as the removals were deemed too disruptive at this time.) - New deprecations <https://docs.python.org/3.13/whatsnew/3.13.html#deprecated>, most of which are scheduled for removal from Python 3.15 or 3.16. (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 3.13, see What’s new in Python 3.13 <https://docs.python.org/3.13/whatsnew/3.13.html>.

ANN: First beta of Python-Blosc2 3.0.0
by Francesc Alted June 21, 2024

June 21, 2024

Hi, The Blosc development team is pleased to announce the first beta release of Python-Blosc2 3.0.0. We have been working hard to provide a new evaluation engine (based on numexpr) for NDArray instances, and we would like to get feedback from the community before the final release. Now, you can evaluate expressions like `a + sin(b) + 1` where `a` and `b` are NDArray instances. This is a powerful feature that allows for efficient computations on compressed data, and supports advanced features like reductions, filters, user-defined functions and broadcasting (still in beta). See this `example <https://github.com/Blosc/python-blosc2/blob/main/examples/ndarray/eval_expr…>`_. Also, we have added support for memory mapping in `SChunk` and `NDArray` instances. This allows to map super-chunks stored in disk and access them as if they were in memory. When combined with the evaluation engine, this feature allows for very good performance when working with large datasets. See this `benchmark <https://github.com/Blosc/python-blosc2/blob/main/bench/ndarray/lazyarray-ex…>`_ (as it is a Jupyter notebook, you can easily run it in your own computer). Last, but not least, we are using NumPy 2.x as the default for testing procedures and builds. This means that our wheels are built against NumPy 2, so in case you want to use NumPy 1.x, you will need to use NumPy 1.23.0 or later. We are providing binary wheels that you can easily install from PyPI with:: pip install blosc2==3.0.0b1 For more info, you can have a look at the release notes in: https://github.com/Blosc/python-blosc2/releases More docs and examples are available in the documentation site: https://www.blosc.org/python-blosc2/python-blosc2.html What is it? ----------- `C-Blosc2 <https://github.com/Blosc/c-blosc2>`_ is the new major version of `C-Blosc <https://github.com/Blosc/c-blosc>`_, and is backward compatible with both the C-Blosc1 API and its in-memory format. Python-Blosc2 is a Python package that wraps C-Blosc2, the newest version of the Blosc compressor. Starting with version 3.0.0, Python-Blosc2 is including a powerful computing engine that can operate on compressed data that can be either in-memory, on-disk or on the network. This engine also supports advanced features like reductions, filters, user-defined functions and broadcasting. You can read some of our tutorials on how to perform advanced computations at: * https://github.com/Blosc/python-blosc2/blob/main/doc/getting_started/tutori… * https://github.com/Blosc/python-blosc2/blob/main/doc/getting_started/tutori… In addition, Python-Blosc2 aims to leverage the full C-Blosc2 functionality to support super-chunks (`SChunk <https://www.blosc.org/python-blosc2/reference/schunk_api.html>`_), multi-dimensional arrays (`NDArray <https://www.blosc.org/python-blosc2/reference/ndarray_api.html>`_), metadata, serialization and other bells and whistles introduced in C-Blosc2. **Note:** Blosc2 is meant to be backward compatible with Blosc(1) data. That means that it can read data generated with Blosc, but the opposite is not true (i.e. there is no *forward* compatibility). Sources repository ------------------ The sources and documentation are managed through github services at: https://github.com/Blosc/python-blosc2 Python-Blosc2 is distributed using the BSD license, see https://github.com/Blosc/python-blosc2/blob/main/LICENSE.txt for details.

ANN: psutil 6.0.0 released
by Giampaolo Rodola' June 18, 2024

June 18, 2024

Hello all, I'm glad to announce the release of psutil 6.0.0: https://github.com/giampaolo/psutil About ===== psutil (process and system utilities) is a cross-platform library for retrieving information on running processes and system utilization (CPU, memory, disks, network) in Python. It is useful mainly for system monitoring, profiling and limiting process resources and management of running processes. It implements many functionalities offered by command line tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free, nice, ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap. It currently supports Linux, Windows, macOS, Sun Solaris, FreeBSD, OpenBSD, NetBSD and AIX. Supported Python versions are 2.7 and 3.6+. PyPy is also known to work. What's new ========== **Enhancements** - #2109: ``maxfile`` and ``maxpath`` fields were removed from the namedtuple returned by `disk_partitions()`_. Reason: on network filesystems (NFS) this can potentially take a very long time to complete. - #2366, [Windows]: log debug message when using slower process APIs. - #2375, [macOS]: provide arm64 wheels. (patch by Matthieu Darbois) - #2396: `process_iter()`_ no longer pre-emptively checks whether PIDs have been reused. This makes `process_iter()`_ around 20x times faster. - #2396: a new ``psutil.process_iter.cache_clear()`` API can be used the clear `process_iter()`_ internal cache. - #2401, Support building with free-threaded CPython 3.13. - #2407: `Process.connections()`_ was renamed to `Process.net_connections()`_. The old name is still available, but it's deprecated (triggers a ``DeprecationWarning``) and will be removed in the future. - #2425: [Linux]: provide aarch64 wheels. (patch by Matthieu Darbois / Ben Raz) **Bug fixes** - #2250, [NetBSD]: `Process.cmdline()`_ sometimes fail with EBUSY. It usually happens for long cmdlines with lots of arguments. In this case retry getting the cmdline for up to 50 times, and return an empty list as last resort. - #2254, [Linux]: offline cpus raise NotImplementedError in cpu_freq() (patch by Shade Gladden) - #2272: Add pickle support to psutil Exceptions. - #2359, [Windows], [CRITICAL]: `pid_exists()`_ disagrees with `Process`_ on whether a pid exists when ERROR_ACCESS_DENIED. - #2360, [macOS]: can't compile on macOS < 10.13. (patch by Ryan Schmidt) - #2362, [macOS]: can't compile on macOS 10.11. (patch by Ryan Schmidt) - #2365, [macOS]: can't compile on macOS < 10.9. (patch by Ryan Schmidt) - #2395, [OpenBSD]: `pid_exists()`_ erroneously return True if the argument is a thread ID (TID) instead of a PID (process ID). - #2412, [macOS]: can't compile on macOS 10.4 PowerPC due to missing `MNT_` constants. **Porting notes** Version 6.0.0 introduces some changes which affect backward compatibility: - #2109: the namedtuple returned by `disk_partitions()`_' no longer has ``maxfile`` and ``maxpath`` fields. - #2396: `process_iter()`_ no longer pre-emptively checks whether PIDs have been reused. If you want to check for PID reusage you are supposed to use `Process.is_running()`_ against the yielded `Process`_ instances. That will also automatically remove reused PIDs from `process_iter()`_ internal cache. - #2407: `Process.connections()`_ was renamed to `Process.net_connections()`_. The old name is still available, but it's deprecated (triggers a ``DeprecationWarning``) and will be removed in the future.

[RELEASE] Python 3.13.0 beta 2 released.
by Thomas Wouters June 7, 2024

June 7, 2024

After a little bit of a delay (I blame the flat tire on my rental car), 3.13.0b2 is released: https://www.python.org/downloads/release/python-3130b2/ <https://www.python.org/downloads/release/python-3130b2/> <https://discuss.python.org/t/3-13-0b2-now-available/55056#this-is-a-beta-pr…>This is a beta preview of Python 3.13 Python 3.13 is still in development. This release, 3.13.0b2, is the second of four beta release previews of 3.13. Beta release previews are intended to give the wider community the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release. We *strongly encourage* maintainers of third-party Python projects to *test with 3.13* during the beta phase and report issues found to the Python bug tracker <https://github.com/python/cpython/issues> as soon as possible. While the release is planned to be 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 (Tuesday 2024-07-30). Our goal is to have no ABI changes after beta 4 and as few code changes as possible after 3.13.0rc1, the first release candidate. To achieve that, it will be *extremely important* to get as much exposure for 3.13 as possible during the beta phase. *Two particularly noteworthy changes in beta 2 involve the macOS installer we provide:* - The minimum supported macOS version was changed from 10.9 to *10.13 (High Sierra)*. Older macOS versions will not be supported going forward. - The macOS installer package now includes an optional additional build of Python 3.13 with the experimental free-threading feature enabled. The free-threaded version, python3.13t, is separate from and co-exists with the traditional GIL-only installation. The free-threaded build is not installed by default; use the Customize option of the installer as explained in the installer readme. Since this is an experimental feature, there may be late-breaking issues found; see the free-threaded macOS build issue <https://github.com/python/cpython/issues/120098> on GitHub for the most recent status. Please keep in mind that this is a preview release and its use is *not* recommended for production environments. <https://discuss.python.org/t/3-13-0b2-now-available/55056#major-new-feature…>Major new features of the 3.13 series, compared to 3.12 Some of the new major new features and changes in Python 3.13 are: <https://discuss.python.org/t/3-13-0b2-now-available/55056#new-features-2>New features - A new and improved interactive interpreter <https://docs.python.org/3.13/whatsnew/3.13.html#a-better-interactive-interp…>, based on PyPy <https://pypy.org>’s, featuring multi-line editing and color support, as well as colorized exception tracebacks <https://docs.python.org/3.13/whatsnew/3.13.html#improved-error-messages> . - An *experimental* free-threaded build mode <https://docs.python.org/3.13/whatsnew/3.13.html#free-threaded-cpython>, which disables the Global Interpreter Lock, allowing threads to run more concurrently. - A preliminary, *experimental* JIT <https://docs.python.org/3.13/whatsnew/3.13.html#experimental-jit-compiler>, providing the ground work for significant performance improvements. - The (cyclic) garbage collector is now incremental <https://docs.python.org/3.13/whatsnew/3.13.html#incremental-garbage-collect…>, which should mean shorter pauses for collection in programs with a lot of objects. - A modified version of mimalloc <https://github.com/microsoft/mimalloc> is now included, optional but enabled by default if supported by the platform, and required for the free-threaded build mode. - Docstrings now have their leading indentation stripped <https://docs.python.org/3.13/whatsnew/3.13.html#other-language-changes>, reducing memory use and the size of .pyc files. (Most tools handling docstrings already strip leading indentation.) - The dbm module <https://docs.python.org/3.13/library/dbm.html> has a new dbm.sqlite3 backend <https://docs.python.org/3.13/whatsnew/3.13.html#dbm> that is used by default when creating new files. <https://discuss.python.org/t/3-13-0b2-now-available/55056#typing-3>Typing - Support for type defaults in type parameters <https://peps.python.org/pep-0696/>. - A new type narrowing annotation <https://peps.python.org/pep-0742/>, typing.TypeIs. - A new annotation for read-only items in TypeDicts <https://peps.python.org/pep-0705/>. <https://discuss.python.org/t/3-13-0b2-now-available/55056#removals-and-new-…>Removals and new deprecations - PEP 594 (Removing dead batteries from the standard library) <https://peps.python.org/pep-0594/> scheduled removals of many deprecated modules: aifc, audioop, chunk, cgi, cgitb, crypt, imghdr, mailcap, msilib, nis, nntplib, ossaudiodev, pipes, sndhdr, spwd, sunau, telnetlib, uu, xdrlib, lib2to3. - Many other removals <https://docs.python.org/3.13/whatsnew/3.13.html#removed> of deprecated classes, functions and methods in various standard library modules. - C API removals <https://docs.python.org/3.13/whatsnew/3.13.html#id10> and deprecations <https://docs.python.org/3.13/whatsnew/3.13.html#id9>. (Some removals present in alpha 1 were reverted in alpha 2, as the removals were deemed too disruptive at this time.) - New deprecations <https://docs.python.org/3.13/whatsnew/3.13.html#deprecated>, most of which are scheduled for removal from Python 3.15 or 3.16. (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 3.13, see What’s new in Python 3.13 <https://docs.python.org/3.13/whatsnew/3.13.html>.
