[general] [bug] Set up full Python 3.13 support to the extent currently possible, repairing
issues within internal language helpers as well as the serializer extension
module.
[orm] [bug] Fixed issue where a MetaData collection would not be
serializable, if an Enum or Boolean datatype were
present which had been adapted. This specific scenario in turn could occur
when using the Enum or Boolean within ORM Annotated
Declarative form where type objects frequently get copied.
[orm] [bug] Fixed issue where the _orm.selectinload() and
_orm.subqueryload() loader options would fail to take effect when
made against an inherited subclass that itself included a subclass-specific
_orm.Mapper.with_polymorphic setting.
[orm] [bug] Fixed very old issue involving the _orm.joinedload.innerjoin
parameter where making use of this parameter mixed into a query that also
included joined eager loads along a self-referential or other cyclical
relationship, along with complicating factors like inner joins added for
secondary tables and such, would have the chance of splicing a particular
inner join to the wrong part of the query. Additional state has been added
to the internal method that does this splice to make a better decision as
to where splicing should proceed.
[orm] [bug] [regression] Fixed bug in ORM Declarative where the __table__ directive could not be
declared as a class function with _orm.declared_attr() on a
superclass, including an __abstract__ class as well as coming from the

I’d also like to thank my employer, Dropbox, for supporting mypy development.
Mypy 1.9
We’ve just uploaded mypy 1.9 to the Python Package Index (PyPI). Mypy is a static type checker for Python. This release includes new features, performance improvements and bug fixes. You can install it as follows:
python3 -m pip install -U mypy
You can read the full documentation for this release on Read the Docs.
Breaking Changes
Because the version of typeshed we use in mypy 1.9 doesn't support 3.7, neither does mypy 1.9. (Jared Hance, PR 16883)

#12355: Fix possible catastrophic performance slowdown on a certain parametrization pattern involving many higher-scoped parameters.
#12367: Fix a regression in pytest 8.2.0 where unittest class instances (a fresh one is created for each test) were not released promptly on test teardown but only on session teardown.
#12381: Fix possible "Directory not empty" crashes arising from concurent cache dir (.pytest_cache) creation. Regressed in pytest 8.2.0.
Improved Documentation
#12290: Updated Sphinx theme to use Furo instead of Flask, enabling Dark mode theme.
#12356: Added a subsection to the documentation for debugging flaky tests to mention
lack of thread safety in pytest as a possible source of flakyness.
#12363: The documentation webpages now links to a canonical version to reduce outdated documentation in search engine results.
If you attempt to combine statement coverage data with branch coverage data,
coverage.py used to fail with the message "Can't combine arc data with line
data" or its reverse, "Can't combine line data with arc data." These
messages used internal terminology, making it hard for people to understand
the problem. They are now changed to mention "branch coverage data" and
"statement coverage data."
Fixed a minor branch coverage problem with wildcard match/case cases using
names or guard clauses.
Started testing on 3.13 free-threading (nogil) builds of Python. I'm not
claiming full support yet. Closes issue 1799_.
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. (patch by Sam Gross)
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.
