Updates sqlalchemy from 2.0.49 to 2.0.52

Release notes

Sourced from sqlalchemy's releases.

2.0.52

Released: August 11, 2026

platform

• [platform] [bug] Python 3.15 support has been added and tested, including minimal changes for full compatibility.

  References: #13477

orm

• [orm] [bug] Fixed a result-column misalignment bug in ORM-enabled UPDATE statements where synchronize_session="fetch" is in use, either explicitly or because the statement uses constructs such as CTEs that implicitly select for it. Columns in rows returned by .returning() could be returned under incorrect keys (e.g. row[SomeClass.a] returning the value of a different column), a problem most likely to manifest under concurrent workloads. ORM DELETE statements were not affected.

  References: #13439

• [orm] [bug] Fixed bug where a failed _orm.Session.bulk_insert_mappings(), _orm.Session.bulk_update_mappings() or _orm.Session.bulk_save_objects() call could leave the _orm.Session permanently in a "flushing" state, such as when the transaction could not be begun because a previous flush had left it needing a rollback. Unlike _orm.Session.flush(), the bulk methods set the internal flushing flag and began the transaction outside of the try/finally block that resets it, so that neither _orm.Session.rollback() nor _orm.Session.close() would clear it, and every subsequent flush would raise InvalidRequestError: Session is already flushing. Pull request courtesy Hamody We.

  References: #13485

• [orm] [bug] Fixed issue where unpickling an ORM object that were loaded using loader options making use of wildcard tokens, such as _orm.load_only() or _orm.raiseload() with "*", would fail with KeyError or IndexError if the process doing the unpickling had not yet constructed a loader path making use of that same token. This would typically be observed when the object were unpickled in a separate process, such as with the spawn or forkserver multiprocessing start methods, the latter of which became the default on POSIX platforms as of Python 3.14. The internal collection of these tokens is now established up front, so that it is identical in every process.

Updates alembic from 1.18.4 to 1.19.1

Release notes

Sourced from alembic's releases.

1.19.1

Released: August 8, 2026

bug

• [bug] [autogenerate] Fixed bug in the check constraint detection implemented in #508 that failed to take into account column bound check constraints, leading to wrong autogenerate detections.

  References: #1842

1.19.0

Released: August 4, 2026

changed

• [changed] [installation] Environmental updates:

  -   Trove classifiers now include Python 3.15 which is now part of CI
      integration
  
  
  Python 3.14 is also added to trove classifiers which had been previously
  omitted
  
  
  Implemented PEP 604 style unions in type annotations
  

feature

• [feature] [autogenerate] Autogenerate now detects the addition and removal of named CHECK constraints, as part of the default autogenerate behavior. Detection is name-based only; a constraint whose name is unchanged is presumed equivalent regardless of its expression text, as reliably normalizing SQL expressions across backends for comparison purposes is not generally feasible. This behavior is implemented as a plugin named alembic.autogenerate.checkconstraint_byname, and may be disabled if not desired by excluding it from the EnvironmentContext.configure.autogenerate_plugins list. Pull request courtesy Francois van Kempen.

Updates pydantic-settings from 2.14.2 to 2.15.0

Release notes

Sourced from pydantic-settings's releases.

v2.15.0

Highlights

Behavior changes

• case_sensitive now applies to init kwargs and config-file sources (#900). InitSettingsSource and the JSON/TOML/YAML config sources previously ignored case_sensitive. Since it defaults to False, case-insensitive matching is now the default for these sources — e.g. Settings(TeSt=...) now populates a test field where it previously did not. Nested keys are still matched case-sensitively.
• Fields with unresolved forward references now emit a warning (#901). Settings sources can silently fail to resolve such fields; they now raise IncompleteFieldDefinitionWarning telling you to call model_rebuild(). If you have filterwarnings = error configured, this may surface as a new failure.
• Non-JSON env values for strict fields now raise ValidationError (#926) instead of a less specific error.

New features

• Show environment variable names in CLI help via cli_show_env_vars=True (#860), so generated --help output doubles as configuration documentation.
• PYDANTIC_SETTINGS_DEBUG for debugging settings resolution (#906, #913). Set it to a truthy value with DEBUG logging enabled to see each source's contribution in priority order, which source won for each value, and which env_file/secret files were probed, loaded, or skipped — the long-standing "why isn't my .env being picked up?" question.
• toml_table_header for regular TOML files (#882, #886, #887), letting you root settings at a nested table in any TOML file, not just pyproject.toml.
• Traversable support for JSON/TOML/YAML file sources (#902), so you can load config packaged inside a distribution — including files inside a zip or wheel — via importlib.resources.files(...) without casting to Path.
• GCP: project_id can come from an earlier settings source (#878), rather than only from the constructor or GOOGLE_CLOUD_PROJECT.

Bug fixes

• Fix env vars not loading on Windows with case_sensitive=True (#894). Windows upper-cases os.environ keys, so fields raised Field required instead of picking up their values.
• Read secret files as UTF-8 instead of the platform locale encoding (#917). On Windows code pages such as cp1252 this silently corrupted non-ASCII secrets.
• Fix AliasPath on nested model fields not JSON-decoding env values (#898).
• Fix case-insensitive matching for optional nested models (#905).
• Fix dotenv extras being wrongly claimed by a complex field sharing a name prefix (#912) — e.g. dbx_token being swallowed by a db: dict field.
• Fix nested_model_default_partial_update=True corrupting discriminated unions (#876).
• Fix Secret subclasses crashing when loaded from the environment (#920).
• Fix enum names not parsing through nested annotations such as Optional[Annotated[MyEnum, ...]] with env_parse_enums=True (#910).
• An empty yaml_config_section now falls back to defaults instead of raising AttributeError: 'NoneType' object has no attribute 'keys' (#914).
• NestedSecretsSettingsSource no longer follows symlinks pointing outside secrets_dir (#889).
• GCP: skip the list_secrets call when case_sensitive=True (#862), lowering the required IAM permissions to just roles/secretmanager.secretAccessor.
• AWS: types-boto3[secretsmanager] is no longer required at runtime (#880).

Documentation

• Document JSON parsing of complex env values, plus a comma-separated-values recipe (#919).
• Recommend an async settings loading pattern (#908).
• Clarify behavior when an unprefixed value is present in a dotenv file (#895).
• Clarify environment variable helper descriptions (#867) and fix assorted typos (#904).

Updates python-dotenv from 1.2.2 to 1.2.3

Release notes

Sourced from python-dotenv's releases.

v1.2.3

Fixed

• Strip a leading UTF-8 BOM from .env file contents so the first variable is no longer silently lost when the file is saved with BOM (e.g. by some JetBrains IDEs on Windows) by [@​h1whelan] in #640
• set_key now escapes backslashes, so values containing them (Windows paths, regular expressions) survive a write/read round-trip. Quoted values ending in an escaped backslash are no longer mis-parsed as an escaped quote, which used to swallow the following lines by [@​dchaudhari7177] in #680
• dotenv run now prints a friendly error instead of a traceback when no command is given by [@​bbc2] in #606
• Cache the parsed result for empty .env files so repeated dotenv_values/load_dotenv calls no longer re-read the file by [@​ReinerBRO] in #638

6.22.2 (2026-08-17)

Bugfix

* (Windows) Fix spurious security validation error when a ``onefile``
  executable is launched from a symlinked directory or a junction.
  (:issue:`9508`)
6.22.1 (2026-08-15)
Bugfix

• Fix invalid spec file generation when :option:--hide-console option is given (regression introduced in v6.22.0). (:issue:9503)
• (NetBSD) Fix binary dependency analysis. (:issue:9505)
• (NetBSD) Fix/improve NetBSD support: add the is_netbsd platform flag, treat NetBSD as a Unix platform, and search /usr/local/lib for shared libraries, as is already done for FreeBSD and OpenBSD. (:issue:9496)
• (OpenBSD) Fix binary dependency analysis. (:issue:9505)

Incompatible Changes

* (POSIX) Executables built in ``onedir`` mode with ``setuid`` bit set
  now validate the owner and permissions on their contents directory
  (typically the ``_internal`` directory); the owner ID must match the
  effective user ID under which the process is running, and the
  permissions on the directory need to be `0700`. This aims to prevent
  unprivileged users from modifying contents of an application that
  runs in privileged mode. (:issue:`9492`)
* (POSIX) When running as a ``onefile`` child process (on POSIX platforms
  other than OpenBSD and AIX), the bootloader now attempts to verify
  the parent process executable via ``procfs`` lookup. This check is
  mandatory for ``onefile`` executables with ``setuid`` bit set; if the
  relevant ``procfs`` entry is inaccessible (for example, due to ``procfs``
  not being mounted, as is the case on FreeBSD by default, or due to access
  being blocked by local security policy), the process will exit with
  security validation error message. For regular ``onefile`` executables
  (without ``setuid`` bit set), the parent-process check is enforced when the
  relevant ``procfs`` entry is accessible, and skipped when it happens to be
  inaccessible. (:issue:`9492`)
* (POSIX) When running as a ``onefile`` child process and the executable
  has ``setuid`` bit set, the bootloader now validates the owner and
  permissions on the (inherited) temporary directory. The owner ID of the
