Python 3.13.0 beta 3 released
I’m pleased to announce the release of Python 3.13 beta 3.
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
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.
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:
New features
- A new and improved interactive interpreter , based on PyPy’s, featuring multi-line editing and color support, as well as colorized exception tracebacks .
- An experimental free-threaded build mode , 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 , providing the ground work for significant performance improvements.
- The (cyclic) garbage collector is now incremental , which should mean shorter pauses for collection in programs with a lot of objects.
- A modified version of 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, reducing memory use and the size of .pyc files. (Most tools handling docstrings already strip leading indentation.)
- The dbm module has a new dbm.sqlite3 backend 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.
Typing
- Support for type defaults in type parameters.
- A new type narrowing annotation ,
typing.TypeIs
. - A new annotation for read-only items in TypeDicts .
Removals and new deprecations
- PEP 594 (Removing dead batteries from the standard library) 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 of deprecated classes, functions and methods in various standard library modules.
- C API removals and deprecations. (Some removals present in alpha 1 were reverted in alpha 2, as the removals were deemed too disruptive at this time.)
- New deprecations, 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.)
For more details on the changes to Python 3.13, see What’s new in Python 3.13 . The next pre-release of Python 3.13 will be 3.13.0b4, currently scheduled for 2024-07-16.

Transform Firefox into the ultimate minimalist browser
Ever feel like the internet is always… yelling? From pop-up windows and ads that autoplay to the sheer size of the internet, a lot of things scream for our attention. This makes it difficult to get things done. Firefox has privacy at its core, making it a great choice for those who want to minimize […]

GNU Health: Migrar, migrant, migràrem
The title of this article, “Migrar, migrant, migrà rem“, comes from a beautiful poem written by Laia Porcar[1], that inspired the strikingly profound painting by Sara Belles [2] “Jo per tu, fill meu“. The artists reflect the migrants ordeal to provide a better life to their children and families, even at the cost of losing their own lives.
GNU Health[3] is a Social project with some technology behind and the mission at Sea-Eye is one of the best examples. After all, GNU Solidario[4] is a NGO that focuses in the advancement of Social Medicine.
We live a world of injustice. Concentration of power, social gradient and poverty rates keep on the rise. Artificial intelligence is on the hands of mega private corporations, targeting our privacy and feeding the macabre business of war. The fight for scarce natural resources such as lithium or coltan creates coups in impoverished countries. Nature and non-human animals are used and abused as mere commodities. Our world turns a blind eye to the systematic crushing and eradication of civilian population by powerful armies. As a result, we live in a world where migration is not a choice, but the only way out for millions of human beings, even at the risk of becoming anonymous victims in the Atlantic ocean or Mediterranean sea mass graveyards.

But there is hope. The Sea-Eye mission is the end result of a network of solidarity, cooperation and empathy. The Free Software movement started by Richard Stallman[5]; Julian Sassencheidt message in Mastodon and his presentation at GNU Health Con 2023[6] ; The work of our representative in Germany, Gerald Wiese; the Chaos Computer Club[7]; the team from L’Aurora[8] providing logistic support to the Search and Rescue vessels; the phenomenal Sea-Eye family who made me feel at home: The cook, crew on deck, the logistics and medical team who stood stoically intensive hours of GNU Health training. Of course, Selene, the heart of GNU Solidario and the one that looks after the human and non-human family members while I’m away.
You will hardly see these people in the news, because most corporate-backed media neglect them and their organizations. Unlike some billionaire “philanthropists” that take the media spotlight, these anonymous heroes stand on the right side of history, making a difference on the present and future of those who need it most, with very limited resources.

We’re very happy and proud to see that GNU Health can be of help to Sea-Eye in tasks such as guests registration, health evaluations, reporting, statistics and stock management. This is just the beginning and we will be optimizing and adding functionality on successive missions. That said, GNU Health will always play a secondary role compared to picking up somebody from the water and giving them a welcoming hug. Again, we’re a social project with a bit of technology behind.

I’d like to finish with a reflection on the picture I took to some of the drawings done by children during their stay at the Sea-Eye. The drawings exist because the Sea-eye crew rescued those kids. Otherwise, their corpses would be at the bottom of the Mediterranean sea, along with thousands who tragically perished trying to find dignity in this world. Thank you, Sea-eye. You are priceless.
A final note: shame on those countries and governments that detain and punish Search and Rescue vessels. Saving lives is not a crime.
Love, freedom and happy hacking
