Updates uvicorn to 0.52.1

Release notes

Sourced from uvicorn's releases.

Version 0.52.1

Fixed

• Complete the closing handshake on server-initiated WebSocket closes in the websockets-sansio and wsproto implementations, waiting for the client's close reply with a 10 second timeout instead of resetting the connection (#3053)
• Add missing write flow control to the websockets-sansio implementation, preventing data truncation on server-initiated closes with large in-flight payloads (#3048)
• Handle connection loss while a WebSocket write is waiting on backpressure (#3050)
• Remove duplicate Content-Type and Content-Length headers from WebSocket denial responses on the websockets-sansio implementation, and deliver non-UTF-8 denial bodies intact (#3041)

0.52.1 (August 1, 2026)

Fixed

• Complete the closing handshake on server-initiated WebSocket closes in the websockets-sansio and wsproto implementations, waiting for the client's close reply with a 10 second timeout instead of resetting the connection (#3053)
• Add missing write flow control to the websockets-sansio implementation, preventing data truncation on server-initiated closes with large in-flight payloads (#3048)

0.52.0 (July 29, 2026)

This release adds an experimental HTTP/1.1 implementation backed by zttp, a sans-IO HTTP parser I've been developing on the side: a core written in Zig, with bindings to Python. It has been running under a fuzzer for some weeks now, and has been through multiple rounds of security auditing.

It is still experimental, so don't put it in front of production traffic yet. Try it with --http zttp, and please send any feedback to the issue tracker.

Added

• Add an experimental zttp HTTP/1.1 implementation, selectable with --http zttp (#2979)

Fixed

• Keep non-ASCII WebSocket request headers intact with websockets 17.0, which encodes them with ISO-8859-1 (#3036)

0.51.0 (July 8, 2026)

Added

• Restart workers one at a time on SIGHUP, bringing each replacement up before retiring the old worker, so reloads no longer drop requests (#3025)

Removed

• Remove colorama from the standard extra (#3027)

0.50.2 (July 6, 2026)

Fixed

• Require websockets>=13.0, which the default websockets-sansio implementation needs (#3021)

0.50.1 (July 6, 2026)

Fixed

• Split comma-separated Sec-WebSocket-Protocol values in the websockets-sansio implementation (#3019)

0.50.0 (July 4, 2026)

If you use WebSockets, note that --ws auto now picks the websockets-sansio implementation. You shouldn't need it, but you can pin --ws websockets to get the deprecated legacy one back.

Updates asyncmy to 0.2.13

Release notes

Sourced from asyncmy's releases.

v0.2.13

Highlights

Binary protocol release — server-side prepared statements land, and the receive path goes zero-copy. On the cross-language benchmark asyncmy's binary scan (22.9ms/50k rows) is now the fastest, ahead of go-sql-driver (32ms) and mysql_async (48ms).

Server-side prepared statements (binary protocol)

stmt = await conn.prepare("SELECT id, name FROM users WHERE id = ?")
result = await stmt.execute((42,))

• Parameters serialize in binary form — no client-side escaping
• Rows parse from the binary protocol in C: integers as little-endian bytes, temporal types via the CPython datetime C-API
• ~35% faster than the text protocol on numeric/datetime-heavy scans

Transparent statement cache

pool = await asyncmy.create_pool(stmt_cache_size=128, ...)

Plain cursor.execute("... %s ...", args) automatically runs as cached server-side prepared statements — ORMs benefit with zero code changes (36.9ms → 25.3ms on 50k-row cursor scans). Unpreparable queries fall back to the text protocol silently. Opt-in because FLOAT columns return the exact stored value under the binary protocol.

Protocol & I/O

• Custom asyncio.BufferedProtocol replaces StreamReader: incoming bytes land directly in the parse buffer (zero-copy receive, no per-read Future round-trips)
• CLIENT_DEPRECATE_EOF negotiated: one packet less per result set and per prepare
• Prepared-statement column metadata cached; repeated executes skip the column definition packets via C-level packet skipping
• MariaDB COM_STMT_BULK_EXECUTE: executemany binds all rows in one round-trip when the statement cache is enabled (also stmt.execute_bulk(rows))
• SSCursor bulk-parses buffered rows; DictCursor builds row dicts at C level

Fixes & build

• Fix LOAD DATA LOCAL INFILE sending (await on a non-coroutine) and add write backpressure
• Fix conftest.py ignoring a non-default MYSQL_PORT
• Linux aarch64 wheels are now published

Full Changelog: long2ice/asyncmy@v0.2.12...v0.2.13

Changelog

Sourced from asyncmy's changelog.

0.2.13

• Add server-side prepared statements (binary protocol): stmt = await conn.prepare(sql), await stmt.execute(args). Parameters are sent in binary form (no client-side escaping) and results are parsed from the binary protocol — no text parsing for numeric/temporal columns. Large scans are ~35% faster than the text protocol; on the cross-language benchmark asyncmy's binary scan is now the fastest, ahead of go-sql-driver and mysql_async.
• Add transparent statement cache: connect(stmt_cache_size=N) makes plain cursor.execute("... %s ...", args) run as cached server-side prepared statements (binary protocol) with silent text-protocol fallback for unpreparable queries. Opt-in because FLOAT columns return the exact stored value under the binary protocol.
• Replace StreamReader with a custom asyncio.BufferedProtocol: incoming bytes land directly in the parse buffer (zero-copy receive, no per-read Future round-trips).
• Cache prepared-statement column metadata: repeated executes skip re-parsing column definition packets entirely (C-level packet skipping).
• SSCursor now bulk-parses buffered rows (unbuffered scans ~10% faster on top of 0.2.12's 2.8x).
• DictCursor builds row dicts at C level.
• Fix LOAD DATA LOCAL INFILE sending (await on a non-coroutine) and add write backpressure.
• Build Linux aarch64 wheels.
• Negotiate CLIENT_DEPRECATE_EOF: one packet less per result set and per prepare (both MySQL 5.7.5+ and MariaDB support it; legacy EOF path kept for older servers).
• MariaDB: support COM_STMT_BULK_EXECUTE — executemany binds all rows in binary form in one round-trip when stmt_cache_size is enabled (automatic text fallback); also available explicitly via stmt.execute_bulk(rows).
• Fix conftest.py ignoring a non-default MYSQL_PORT.

0.2.12

• Major performance improvement: buffered packet reading, C-level bulk row parsing, pointer-based protocol reads, direct cell decoding via CPython C-API, zero-decode numeric/temporal columns, escape fast path. Large result sets are 5-15x faster; asyncmy now ranks #1 in all benchmarks, details see https://github.com/long2ice/asyncmy/blob/dev/benchmark/README.md.
• Fix OKPacketWrapper.message containing 2 stray bytes (read_struct position bug).
• Fix LoadLocalPacketWrapper missing attribute declarations (LOAD DATA LOCAL crash).
• Fix potential integer overflow of rowcount/insert_id on unbuffered cursors and Windows.
• Benchmark suite now uses warmup + best-of-3 methodology.
• Security: remove unsafe escape_dict — dict keys could reach SQL unescaped (CVE-2025-65896). (#134, #135, thanks @​Cycloctane)
• Fix AttributeError: 'Connection' object has no attribute 'ssl' in sha256_password auth branch. (#147, #148, thanks @​shychee)
• Support MySQL 8.0.19+ INSERT ... AS alias ON DUPLICATE KEY UPDATE syntax in executemany. (#116, #120, thanks @​MarkReedZ)
• Pool closes idle/recycled connections with QUIT instead of aborting the TCP stream. (#112, #113, thanks @​Cycloctane)
• Fix OverflowError when escaping ints outside the signed 64-bit range, e.g. unsigned BIGINT 2**64-1. (#35, #127)
• Close connection when a query is cancelled mid-read to prevent stale results leaking into pooled reuse. (#107, #108)
• Use setuptools instead of deprecated distutils in build. (#106, thanks @​tijuca)

0.2.11

• Fix 'Connection' object has no attribute '_auth_plugin_name' (#86)

0.2.10

Updates pydantic-settings 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 redis to 8.1.0

Release notes

Sourced from redis's releases.

8.1.0

Changes

✨ Highlights

Async maintenance notifications

redis-py now supports server-pushed maintenance notifications in the asyncio stack for both standalone and cluster clients, bringing the async client to parity with the sync implementation. When a Redis deployment signals maintenance events (such as node migration or failover windows), the async client reacts through the maintenance-notifications handler (redis/maint_notifications.py and its async integration under redis/asyncio/), allowing applications to adapt connection handling during maintenance without downtime. (#4177)

Expanded command coverage

This release adds a batch of new command surfaces across core data types and modules:

• Lists — LMOVEM / BLMOVEM for moving multiple elements between lists (#4174).
• Sets — SDIFFCARD and SUNIONCARD cardinality commands (#4171).
• Streams — MAXCOUNT / MAXSIZE options for XREAD and XREADGROUP (#4173).
• Time Series — TS.READ (#4170), TS.QUERYLABELS (#4197), TS.NRANGE / TS.NREVRANGE (#4163), and an exclude_empty (EXCLUDEEMPTY) option for TS.MRANGE / TS.MREVRANGE (#4188).
• Search — FT.ALIASLIST (#4198) and a COLLECT reducer for aggregations (#4179).
• Sentinel — replica sentinel aliases (#4127).

🚀 New Features

• Add replica sentinel aliases (#4127)
• Add TS.NRANGE and TS.NREVRANGE support to the timeseries command surface (#4163)
• feat: add TS.READ command support to the timeseries module (#4170)

⚠️ Experimental

• feat: add client-side HIMPORT fieldset support for standalone and cluster clients (#4205)

The feature considered unstable and public API might be changed in the future minor version
