1.18.4

Released: February 10, 2026

bug

  • [bug] [operations] Reverted the behavior of Operations.add_column() that would automatically render the "PRIMARY KEY" keyword inline when a Column with primary_key=True is added. The automatic behavior, added in version 1.18.2, is now opt-in via the new Operations.add_column.inline_primary_key parameter. This change restores the ability to render a PostgreSQL SERIAL column, which is required to be primary_key=True, while not impacting the ability to render a separate primary key constraint. This also provides consistency with the Operations.add_column.inline_references parameter and gives users explicit control over SQL generation.

    To render PRIMARY KEY inline, use the Operations.add_column.inline_primary_key parameter set to True:

    op.add_column( "my_table", Column("id", Integer, primary_key=True), inline_primary_key=True )References: #1232

1.18.3

Released: January 29, 2026

bug

  • [bug] [autogenerate] Fixed regression in version 1.18.0 due to #1771 where autogenerate would raise NoReferencedTableError when a foreign key constraint referenced a table that was not part of the initial table load, including tables filtered out by the EnvironmentContext.configure.include_name callable or tables in remote schemas that were not included in the initial reflection run.

    The change in #1771 was a performance optimization that eliminated additional reflection queries for tables that were only referenced by foreign keys but not explicitly included in the main reflection run. However, this optimization inadvertently removed the creation of Table objects for these referenced tables, causing autogenerate to fail when processing foreign key constraints that pointed to them.

    The fix creates placeholder Table objects for foreign key targets

Updates httpx from 0.27.0 to 0.28.1

Release notes

Sourced from httpx's releases.

Version 0.28.1

0.28.1 (6th December, 2024)

  • Fix SSL case where verify=False together with client side certificates.

Version 0.28.0

0.28.0 (28th November, 2024)

The 0.28 release includes a limited set of deprecations.

Deprecations:

We are working towards a simplified SSL configuration API.

For users of the standard verify=True or verify=False cases, or verify=<ssl_context> case this should require no changes. The following cases have been deprecated...

  • The verify argument as a string argument is now deprecated and will raise warnings.
  • The cert argument is now deprecated and will raise warnings.

Our revised SSL documentation covers how to implement the same behaviour with a more constrained API.

The following changes are also included:

  • The deprecated proxies argument has now been removed.
  • The deprecated app argument has now been removed.
  • JSON request bodies use a compact representation. (#3363)
  • Review URL percent escape sets, based on WHATWG spec. (#3371, #3373)
  • Ensure certifi and httpcore are only imported if required. (#3377)
  • Treat socks5h as a valid proxy scheme. (#3178)
  • Cleanup Request() method signature in line with client.request() and httpx.request(). (#3378)
  • Bugfix: When passing params={}, always strictly update rather than merge with an existing querystring. (#3364)

Version 0.27.2

0.27.2 (27th August, 2024)

Fixed

  • Reintroduced supposedly-private URLTypes shortcut. (#2673)

Version 0.27.1

0.27.1 (27th August, 2024)

Added

  • Support for zstd content decoding using the python zstandard package is added. Installable using httpx[zstd]. (#3139)

Fixed

  • Improved error messaging for InvalidURL exceptions. (#3250)
  • Fix app type signature in ASGITransport. (#3109)

0.28.1 (6th December, 2024)

  • Fix SSL case where verify=False together with client side certificates.

0.28.0 (28th November, 2024)

Be aware that the default JSON request bodies now use a more compact representation. This is generally considered a prefered style, tho may require updates to test suites.

Updates python-dotenv from 1.0.1 to 1.2.2

Release notes

Sourced from python-dotenv's releases.

v1.2.2

Added

  • Support for Python 3.14, including the free-threaded (3.14t) build. (#)

Changed

  • The dotenv run command now forwards flags directly to the specified command by @​bbc2 in theskumar/python-dotenv#607
  • Improved documentation clarity regarding override behavior and the reference page.
  • Updated PyPy support to version 3.11.
  • Documentation for FIFO file support.
  • Support for Python 3.9.

Fixed

Breaking Changes

  • dotenv.set_key and dotenv.unset_key used to follow symlinks in some situations. This is no longer the case. For that behavior to be restored in all cases, follow_symlinks=True should be used.

  • In the CLI, set and unset used to follow symlinks in some situations. This is no longer the case.

  • dotenv.set_key, dotenv.unset_key and the CLI commands set and unset used to reset the file mode of the modified .env file to 0o600 in some situations. This is no longer the case: The original mode of the file is now preserved. Is the file needed to be created or wasn't a regular file, mode 0o600 is used.

Updates sqlalchemy from 2.0.29 to 2.0.50

Release notes

Sourced from sqlalchemy's releases.

2.0.50

Released: May 24, 2026

orm

  • [orm] [bug] Fixed issue where using _orm.joinedload() with PropComparator.of_type() targeting a joined-table subclass combined with PropComparator.and_() referencing a column on that subclass would generate invalid SQL, where the subclass column was not adapted to the subquery alias. Pull request courtesy Joaquin Hui Gomez.

    References: #13203

  • [orm] [bug] Fixed issue where the presence of a SessionEvents.do_orm_execute() event hook would cause internal execution options such as yield_per and loader-specific state from the first orm_pre_session_exec pass to leak into the second pass, leading to errors when using relationship loaders such as selectinload() and immediateload(). The execution options passed to the second compilation pass are now based on the original options plus only the explicit updates made via ORMExecuteState.update_execution_options() within the event hook.

    References: #13301

  • [orm] [bug] Fixed issue where using _orm.with_polymorphic() on a leaf class (a subclass with no further descendants) or a non-inherited class would fail with an AttributeError when used in an ORM statement, due to _orm.configure_mappers() not being triggered implicitly. The fix ensures that AliasedInsp participates in the _post_inspect hook, triggering mapper configuration during ORM statement compilation.

    References: #13319

sql

  • [sql] [bug] Fixed issue where floor division (//) between a Float or Numeric numerator and an Integer denominator would omit the FLOOR() SQL wrapper on dialects where Dialect.div_is_floordiv is True (the default, including PostgreSQL and SQLite). FLOOR() is now applied if either the denominator or the numerator is a non-integer, so that expressions such as float_col // int_col render as FLOOR(float_col / int_col) instead of the incorrect float_col / int_col. Pull request courtesy r266-tech.

Updates tzdata from 2024.1 to 2024.2

Release notes

Sourced from tzdata's releases.

2024.2: Release of upstream tzdata 2024b

Version 2024.2

Upstream version 2024b released 2024-09-04T19:27:47+00:00

Briefly:

Improve historical data for Mexico, Mongolia, and Portugal. System V names are now obsolescent. The main data form now uses %z. The code now conforms to RFC 8536 for early timestamps. Support POSIX.1-2024, which removes asctime_r and ctime_r. Assume POSIX.2-1992 or later for shell scripts. SUPPORT_C89 now defaults to 1.

Changes to past timestamps

Asia/Choibalsan is now an alias for Asia/Ulaanbaatar rather than being a separate Zone with differing behavior before April 2008. This seems better given our wildly conflicting information about Mongolia's time zone history. (Thanks to Heitor David Pinto.)

Historical transitions for Mexico have been updated based on official Mexican decrees. The affected timestamps occur during the years 1921-1927, 1931, 1945, 1949-1970, and 1981-1997. The affected zones are America/Bahia_Banderas, America/Cancun, America/Chihuahua, America/Ciudad_Juarez, America/Hermosillo, America/Mazatlan, America/Merida, America/Mexico_City, America/Monterrey, America/Ojinaga, and America/Tijuana. (Thanks to Heitor David Pinto.)

Historical transitions for Portugal, represented by Europe/Lisbon, Atlantic/Azores, and Atlantic/Madeira, have been updated based on a close reading of old Portuguese legislation, replacing previous data mainly originating from Whitman and Shanks & Pottenger. These changes affect a few transitions in 1917-1921, 1924, and 1940 throughout these regions by a few hours or days, and various timestamps between 1977 and 1993 depending on the region. In particular, the Azores and Madeira did not observe DST from 1977 to 1981. Additionally, the adoption of standard zonal time in former Portuguese colonies have been adjusted: Africa/Maputo in 1909, and Asia/Dili by 22 minutes at the start of 1912. (Thanks to Tim Parenti.)

Changes to past tm_isdst flags

The period from 1966-04-03 through 1966-10-02 in Portugal is now modeled as DST, to more closely reflect how contemporaneous changes in law entered into force.

Changes to data

Names present only for compatibility with UNIX System V (last released in the 1990s) have been moved to 'backward'. These names, which for post-1970 timestamps mostly just duplicate data of geographical names, were confusing downstream uses. Names moved to 'backward' are now links to geographical names. This affects behavior for TZ='EET' for some pre-1981 timestamps, for TZ='CET' for some pre-1947 timestamps, and for TZ='WET' for some pre-1996 timestamps.
