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 Now, when the copied fill_value is no longer valid for the new dtype, fall back to the default fill_value for that dtype instead of propagating the stale value.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)

Updates aberrant from 0.5.0 to 1.0.0

Changelog

Sourced from aberrant's changelog.

[1.0.0] - 2026-09-07

Added

• Documented compatibility policy for the stable public API.
• Release tag/version validation before distribution builds and publication.
• API reference entries for ModelPipeline and TransformerPipeline, with documentation rebuilds triggered by package source changes.
• 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.
• MIDAS graph-stream detector in aberrant.model.graph with public export, 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.
