Updates sqlalchemy from 2.0.52 to 2.0.54

Release notes

Sourced from sqlalchemy's releases.

2.0.54

Released: September 15, 2026

platform

• [platform] [change] Binary wheels are no longer built for Python 3.7. PyPI now rejects wheel files whose filename does not begin with the normalized project name, and the packaging tools that can be installed on Python 3.7 do not produce such a filename. As a result, SQLAlchemy 2.0.44 was the last release to publish Python 3.7 wheels to PyPI, and releases 2.0.45 and later have been available on Python 3.7 only as a source distribution; the wheel builds for Python 3.7 are now removed. Python 3.7 remains supported by the 2.0 series.

• [platform] [bug] Fixed issue where the Cython extensions were compiled without the freethreading_compatible directive, so that they did not declare themselves as safe to run without the GIL. On a free-threaded Python interpreter such as Python 3.13t or 3.14t, importing SQLAlchemy would cause the interpreter to re-enable the GIL, emitting a RuntimeWarning. The directive is now set when building for Python 3.13 and above, and a test has been added which confirms that importing SQLAlchemy on a free-threaded build does not enable the GIL.

  References: #13592

2.0.53

Released: September 14, 2026

orm

• [orm] [bug] Fixed issue where an expression passed to _orm.with_expression() that embedded a _sql.select(), such as a correlated _sql.exists(), would fail to populate the attribute correctly on the second and subsequent executions of an otherwise identical statement, when the _orm.query_expression() attribute was loaded by a relationship loader that emits a second query, i.e. _orm.selectinload(), _orm.lazyload() or _orm.immediateload().

  References: #13560

• [orm] [bug] Fixed memory issue where mapped classes, along with their Table and _orm.Mapper objects, would not be garbage collected after the _orm.registry in which they were mapped had been disposed and dereferenced. The issue would occur for mappings that made use of _orm.relationship() together with constructs such as an

Updates uvicorn from 0.52.4 to 0.53.0

Release notes

Sourced from uvicorn's releases.

Version 0.53.0

🌐 Opt-in HTTP/2 support

uvicorn 0.53.0 adds experimental HTTP/2 through zttp, alongside a new zuvloop integration and connection-handling improvements.

uv add uvicorn==0.53.0

• Serve HTTP/1.1 and HTTP/2 with zttp (#2982, #3101). Install zttp, then enable HTTP/2 with --http zttp --http2. Uvicorn negotiates HTTP/2 over TLS with ALPN and supports cleartext prior knowledge.
• HTTP/2 remains experimental. Upgrade-based h2c and WebSockets over HTTP/2 are not supported.

⚙️ More event loop choice

• Run Uvicorn with zuvloop (#3104). Install zuvloop separately and select it explicitly with --loop zuvloop on CPython 3.14 or newer.

🛡️ More reliable connections and proxies

• Honor Connection: close token lists (#3103). Uvicorn now parses comma-separated tokens case-insensitively across HTTP implementations.
• Trust IPv6 loopback proxies by default (#3119). The default FORWARDED_ALLOW_IPS value now includes ::1.
• Keep upgraded WebSockets alive (#3107). Uvicorn cancels the HTTP keep-alive timer when the connection becomes a WebSocket.

Updates numpy from 2.5.2 to 2.5.3

Release notes

Sourced from numpy's releases.

v2.5.3 (Sep 6, 2026)

NumPy 2.5.3 Release Notes

The NumPy 2.5.3 is a patch release that fixes bugs discovered after the 2.5.2 release. Apart from the usual bug and maintenance work, there are a number of StringDType related fixes for problems discovered during the ongoing string work in the main branch.

This release supports Python versions 3.12-3.15

Changes

• Casting a fixed-width byte string array (np.bytes_) to StringDType now raises TypeError when the bytes are not valid UTF-8. Previously the invalid bytes were stored as-is and later caused undefined behavior in string operations.

  (gh-32296)

• MaskedArray._fill_value would become stale when ufuncs that change dtype left the result holding a fill_value typed for the old dtype. The mismatch was silent until something later called _check_fill_value, such as .view(), and then a TypeError would be raised. Now, when the copied fill_value is no longer valid for the new dtype, fall back to the default fill_value for that dtype instead of propagating the stale value. This may raise a ComplexWarning if the fill_value is complex and the new dtype is real.

  (gh-32423)

• Public API exports for aberrant.model.svm, aberrant.model.stat, aberrant.stream, aberrant.transform, and deep lazy exports.
• Regression tests for feature-order stability in OnlineIsolationForest.
• Regression tests for keys= initialization in multivariate statistical models.
• Optional dependency extras for benchmark tooling.
• Repository standards and CI/security/release workflows.
• OnlineAutoencoderEnsemble deep detector with phased warm-up, tests, docs, and an example script.
• MStream sketch-based streaming detector with aberrant.model.sketch public API, unit/integration tests, docs, and example script.
• StreamingLODA sketch-based detector with aberrant.model.sketch public API, unit/integration tests, docs, and an example script.
• SDOStream bounded-memory observer-based detector in aberrant.model.distance with unit/integration tests, docs, and example script.

• AnoEdgeL graph-stream detector in aberrant.model.graph with public export, unit/integration tests, docs, and example script.
• XLagDAMP pure-online time-series discord detector based on the original authors' X-Lag Amnesic DAMP implementation, with bounded history, reference formula tests, synthetic integration coverage, docs, and example script.
• Production hardening CI jobs for base-install smoke and optional-extras smoke.
• Trusted SHA256 checksums for built-in dataset artifacts.
• py.typed marker for downstream type-checker support.
• Stateful FeatureSchema, MonotonicClock, NumericEventBoundary, and EdgeEventBoundary components with explicit preview/commit semantics.
• Typed dataset cache, metadata, download, validation, and stream components.

Changed

• Mondrian and random-histogram trees now represent leaves and branches separately, with complete bounds and children instead of optional node fields.

• Paper-derived custom variants now have accurate canonical public names: CellNeighborhoodDetector, StationaryRegionNeighborDetector, SignedGraphSketchDetector, OnlineAutoencoderEnsemble, MondrianIsolationForest, StreamingRSHash, and StreamingLODA.

• StreamRandomHistogramForest now uses max_depth exclusively; the historical max_bins parameter and attribute were removed. Per-node random values are generated lazily so memory scales with visited nodes instead of complete-tree capacity. Exact seeded score sequences may change under the new derivation.

• OnlineIsolationForest now enforces deterministic feature ordering and key-set checks.

• Dataset module version now uses aberrant.__version__ as single source of truth.
