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 Now, when the copied fill_value is no longer valid for the new dtype, fall back to the default fill_value for that dtype instead of propagating the stale value.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

• #32235: MAINT: Prepare 2.5.x for further development

... (truncated)

Sourced from numpy's changelog.

This is a walkthrough of the NumPy 2.4.0 release on Linux, which will be the first feature release using the numpy/numpy-release <https://github.com/numpy/numpy-release>__ repository.

The commands can be copied into the command line, but be sure to replace 2.4.0 with the correct version. This should be read together with the :ref:general release guide <prepare_release>.

Facility preparation

Before beginning to make a release, use the requirements/*_requirements.txt files to ensure that you have the needed software. Most software can be installed with pip, but some will require apt-get, dnf, or whatever your system uses for software. You will also need a GitHub personal access token (PAT) to push the documentation. There are a few ways to streamline things:

• Git can be set up to use a keyring to store your GitHub personal access token. Search online for the details.

Prior to release

Add/drop Python versions

When adding or dropping Python versions, multiple config and CI files need to be edited in addition to changing the minimum version in pyproject.toml. Make these changes in an ordinary PR against main and backport if necessary. We currently release wheels for new Python versions after the first Python RC once manylinux and cibuildwheel support that new Python version.

Backport pull requests

Changes that have been marked for this release must be backported to the maintenance/2.4.x branch.

Update 2.4.0 milestones

Look at the issues/prs with 2.4.0 milestones and either push them off to a later version, or maybe remove the milestone. You may need to add a milestone.

4.5.1

Couple little things for EnumField.

• EnumField and IntEnumField validate member value types (str and int respectively) at field construction.
• EnumField and IntEnumField default choices to (value, name) pairs derived from the enum.
• Fix #3075, migration generation for EnumField. Generated migrations will emit the storage field type (e.g. IntegerField) rather than EnumField().

4.5.0

Backwards-incompatible:

• MySQL and MariaDB connections no longer set sql_mode. Peewee had been setting PIPES_AS_CONCAT, but the param replaced the server's mode rather than adding to it, which silently disabled STRICT_TRANS_TABLES (etc). Going forward Peewee will not modify sql_mode by default and use CONCAT() rather than || for MySQL/MariaDB.
• MySQL and MariaDB connection charset defaults to utf8mb4 instead of utf8, which is an alias for utf8mb3 and cannot store 4-byte characters.
• A field's sequence= is now qualified with the model's Meta.schema. If the name you pass already contains a dot it is treated as fully-qualified and used as-is, so sequence='other.seq' is unaffected by Meta.schema. Also, sequence_exists() accepts a schema-qualified name.
• SQLite BEGIN, COMMIT and ROLLBACK are issued directly on a cursor rather than through execute_sql(), so they are no longer debug-logged, do not fire query hooks and are not counted by count_queries(). This matches Postgres and MySQL.
• atomic() and transaction() on a closed database with autoconnect=False now raise InterfaceError on Postgres and MySQL, as they already did on SQLite (and as queries do). Previously begin() opened a connection regardless of autoconnect.

Improvements:

• Add SqliteDatabase(..., lock_type=...) to set the default locking strategy for transactions that do not specify one, e.g. lock_type='IMMEDIATE'.
• Postgres introspection (get_tables(), get_columns(), get_indexes(), get_primary_keys(), get_foreign_keys(), get_views()) with no schema now follows the search path via current_schema() instead of assuming public, matching MySQL's DATABASE() behavior.
• Add Runner(db, schema=...) and pwmigrate --schema for running migrations against a specific schema. The history table lives in that schema, so each schema tracks its own applied set and one set of migration files can be run against any number of schemas.
• Add SchemaMigrator(db, schema=...), which qualifies every table name w/the given schema (or database on MySQL). Not supported for SQLite, as the table-rebuild rewrites DDL straight from sqlite_master.

Version 1.45.0/0.66b0

Added

• opentelemetry-exporter-prometheus: add support to configure Resource attributes as metric labels (#5122)
• infra: add renovate (#5202)
• opentelemetry-api, opentelemetry-sdk: add support for extended attribute values everywhere. (#5266)
• opentelemetry-sdk: wire the top-level log_level field in declarative configuration — when set, maps the OTel SeverityNumber value to a Python logging level and applies it to the opentelemetry logger so SDK internal diagnostics respect the configured severity. (#5351)
• opentelemetry-sdk: add the new stable AlwaysRecordSampler (#5354)
• opentelemetry-configuration, opentelemetry-sdk: wire top-level attribute_limits into per-signal providers via declarative config; add log_record_limits support to LoggerProvider (#5365)
• opentelemetry-exporter-otlp-json-http: add OTLP JSON HTTP exporter package (#5374)
• opentelemetry-api, opentelemetry-sdk: add enabled() support to the Logger API, SDK, and LogRecordProcessor to let instrumentation skip expensive work when logging is disabled (#5380)
• opentelemetry-exporter-otlp-json-file: add OTLP JSON file Docker tests (#5412)
• opentelemetry-configuration: wire the experimental tracer_configurator/development, meter_configurator/development and logger_configurator/development fields into create_tracer_provider, create_meter_provider and create_logger_provider, so per-instrumentation-scope enabled overrides declared in the config file are applied to the provider (previously these fields were parsed but silently discarded). The logger minimum_severity/trace_based fields are not supported by the Python SDK and are ignored with a warning. (#5418)
• docs/examples: add example on how to manually setup the SDK to get SDK metrics (#5449)
• opentelemetry-docker-tests: add Prometheus exporter docker tests (#5457)
• opentelemetry-sdk: count records dropped after shutdown on otel.sdk.processor.{span,log}.processed with error.type=already_shutdown (batch span/log and simple log processors), which the semantic conventions define as a valid value for this metric. (#5509)
• opentelemetry-semantic-conventions: update semantic conventions to v1.44.0 (#5511)
• opentelemetry-sdk: add host.id to the host resource detector (#5653)
• opentelemetry-test-utils: add CapturingSampler to record what samplers receive in instrumentation tests (#5681)

Changed

• Enable PIE (flake8-pie) ruff rule and fix all violations (#5150)
• The public opentelemetry.util.types.AttributeValue type in package opentelemetry-api is being expanded to include None, heterogeneous sequences of primitive types (and nested sequences) as opposed to only homogeneous primitive sequences, and Mappings of strings to any primitive types or sequences/mappings (which themselves must only contain primitive types or sequences/mappings validated the same way). If a bytes type is set as an attribute value in the SDK, it will no longer be utf-8 decoded to a string, instead it will be passed along as is in accordance with the OTEL spec, since bytes is a valid type in the OTLP proto. (#5266)
• opentelemetry-exporter-otlp-proto-http: add a max_request_size argument to the OTLP HTTP exporters (traces, logs, metrics); serialized requests larger than the limit are dropped before sending, measured before compression. Defaults to 64 MiB (enabled); set to 0 to disable. Mirrors opentelemetry-go#8157. (#5369)
• [BREAKING] opentelemetry-api: subclasses of Logger need to implement the enabled method (#5380)
• opentelemetry-exporter-otlp-proto-http: refactor to use shared opentelemetry-exporter-otlp-common and opentelemetry-exporter-http-transport packages and switch default HTTP backend to urllib3 (#5389)
• opentelemetry-sdk: unify logging force_flush timeout defaults to 30000ms (#5438)
• opentelemetry-python: enable Ruff default ruleset and fix auto-fixable lint issues (#5491)
• opentelemetry-sdk: SimpleSpanProcessor now drops spans ended after shutdown() instead of passing them to the exporter, and counts them on otel.sdk.processor.span.processed with error.type=already_shutdown. (#5512)
• Bump pytest to 9.0.3 (#5518)
• opentelemetry-exporter-otlp-proto-http: clarify that the endpoint= kwarg requires the full signal path (#5633)
• opentelemetry-sdk: fix typos in SpanLimits docstring (#5658)

Fixed

• opentelemetry-configuration: perform environment variable substitution on scalar values after parsing the configuration file, so ${VAR} references inside comments and mapping keys are no longer substituted and undefined references in comments no longer abort loading (#5407)
• opentelemetry-configuration: declarative config environment variable substitution now replaces an unset variable that has no default with an empty value instead of raising an error, per the configuration spec. Resource attributes whose value resolves to null (an unset ${VAR} with no default) are skipped with a warning instead of being inserted as a null value. (#5408)
• 'scripts/build.sh: add opentelemetry-configurationandopentelemetry-proto-json` to the package to release (#5425)
• opentelemetry-sdk: fix View instrument-name matching so a view configured with an instrument's real (mixed-case) name is applied; matching is now case-insensitive and platform-independent instead of relying on fnmatch's OS-dependent case handling (#5430)
• opentelemetry-sdk: fix missing f-prefix in exponential histogram error messages (#5434)
• opentelemetry-configuration: resolve false-positive warning logs for newer schema minor version (#5436)
• opentelemetry-sdk: make methods on FixedSizeExemplarReservoirABC thread safe (#5437)
• opentelemetry-propagator-jaeger: fix typing issues and enable pyright typechecking for the package opentelemetry-propagator-jaeger: skip uberctx- baggage headers with an empty value on extraction instead of raising TypeError (#5440)
• opentelemetry-sdk: fix TypeError when instantiating a _BaseConfigurator subclass whose __init__ takes arguments (#5441)
• opentelemetry-sdk: fix TypeError in os.fork() when a BatchProcessor or PeriodicExportingMetricReader is garbage collected (#5453)
• opentelemetry-configuration: a declarative config key present with an empty (null) value on an object-typed node (e.g. always_on:, a - service: detector, or a metric console: exporter) is now treated the same as an explicit empty config (always_on: {}) instead of failing type dispatch or silently skipping the node. Both dict-typed nodes and dataclasses constructible with no arguments are covered. (#5454)
• opentelemetry-api: fix copy-pasted log message in SpanContext.__delattr__ (#5455)
• opentelemetry-sdk: reject views with ExponentialBucketHistogramAggregation for asynchronous instruments instead of silently producing no data (#5461)
• Description has been truncated
