Sourced from asyncpg's releases.

v0.32.0

Improvements

• Support Python 3.15 (#1367, #1378) (by @​elprans in 1b118464 and 58c0c595)

• Support PostgreSQL 19 (#1379) (by @​elprans in 8d2a5aed)

• Make pool min_size a maintained connection floor and add init_size to control the number of connections opened at startup (#1323). Idle connections at or below min_size are retained, and closed connections are replaced in the background. init_size defaults to min_size. To preserve the previous behavior, where the pool could drain to zero, replace min_size=N with init_size=N, min_size=0. (by @​shatilov-diman in 67a1cbc5)

• Use hashlib.pbkdf2_hmac() for faster SCRAM password derivation (#1359) (by @​twelfthlabor in 00319a9b)

• Use the statement cache for copy_records_to_table() introspection (#1360) (by @​matemax in dd058652)

Fixes

• Clean up connections rejected by target_session_attrs immediately so an unresponsive rejected host cannot delay the selected connection, and cleanup tasks cannot outlive the event loop. Rejected connections are aborted without waiting for a graceful disconnect; servers may log "unexpected EOF on client connection" if the Terminate message is not delivered before the transport closes.

• Fix a connection pool deadlock when releasing a connection after a protocol abort (#1324) (by @​pchaseh in 4a83cc2f)

• Honor Connection.close(timeout=...) while waiting for a pending cancellation (#1361) (by @​gyanu2507 in c06bcb4d)

• Prevent stuck cancellation from blocking connection teardown or pool release by bounding cancellation with the command or release timeout (#1370) (by @​elprans in 4cf02203)

• Preserve the server error when the connection closes mid-operation (#1369) (by @​RitiGrover in 6c8f1a7a)

• Fix COPY cleanup when a records generator raises, preserving the original exception and avoiding protocol desynchronization and stalled rollback (#1358) (by @​CodingCossack in fdc6bc8f)

Release v1.183.0

1.183.0 - 2026-10-29

### Added

• The --help output of semgrep subcommands now includes a "THIRD-PARTY LICENSES" section linking to the licenses and notices for Semgrep's open source dependencies at https://semgrep.dev/cli-credits. (cli-credits)
• Pro: Supply Chain now records which Go module requires which when dependency paths are enabled and local builds are allowed, so transitive Go findings can show the dependency path. (SC-4268)

### Changed

• Semgrep no longer ships binaries for Intel Macs; 1.182 is the last release that supports them. On Intel Macs, use the semgrep/semgrep Docker image; on Apple Silicon, use a native arm64 Python. (drop-intel-macos)

• Speed up scans with many rules that share file prefilter conditions by checking each condition once per file. (prefilter-predicate-memo)

• semgrep ci --no-suppress-errors now exits with code 2 (instead of 0) when dependency resolution fails for a subproject while local builds are allowed (--allow-local-builds): a build or package manager command fails, a lockfile cannot be parsed at all, or a build succeeds but reports an incomplete dependency list (for example, a registry refused a request). The affected dependency sources are listed in the scan output and the scan no longer reports that it completed successfully. Findings from the other subprojects are still reported. The default behavior, where errors are suppressed, is unchanged, and so is any scan without --allow-local-builds. Semgrep Managed Scanning scans are not affected. (SC-3613)

• bash grammar update (v0.25.1):

  • Bash arithmetic ($(( )), $[ ], (( )), C-style for headers) is now translated into operator trees with bash precedence, so patterns such as $(( $X * 2 )) match structurally. $((...)) is no longer confused with $(...).
  • Bash patterns accept a lone ... before done, fi or }, e.g. while ...; do ... done, and until loops now parse as loops.
  • Bash words containing # (x=foo#bar) are no longer truncated, and arguments after a redirect or heredoc delimiter stay with their command.
  • Many Bash constructs that failed to parse now parse, e.g. $[ ], time ( ... ), extglob in case and [[ ]], and if function bodies.

  (bash-v0.25.1)

• clojure grammar update (v0.0.13):

  • Clojure source parsing now accepts reader-evaluated metadata, such as ^#=(keyword "a") [1 2], including the legacy #^ prefix. Semgrep does not execute reader evaluation, and metadata remains ignored during matching.
  • Clojure source parsing now supports reader conditionals inside symbolic values, such as ## #?(:clj Inf :cljs NaN), retaining the conditional branches without evaluating them.

  (clojure-v0.0.13)

• swift grammar update (0.5.0):

  • Swift parsing now supports type and value parameter packs, including each/repeat expansions and pack constraints.
  • Swift parsing now supports if and switch expressions used as variable initializers.
  • Swift parsing now supports macro declarations with typed signatures and #externalMacro definitions. This does not implement macro expansion.
  • Swift property observers now retain their willSet/didSet bodies and parameters separately from property initializers.
  • Swift parsing now supports borrowing, consuming, package, and distributed modifiers while preserving their distinct spellings.
  • Swift parsing now supports #unavailable conditions and distinguishes them from #available conditions. Both are mapped as #… expression nodes (not boolean Not) so patterns like if !$X do not match availability checks.
  • Swift parsing now supports member access on parenthesized existential types, such as (any P).self, and preserves the underlying parenthesized existential or opaque type.
  • Swift parsing now supports references to the bitwise AND operator using (&).

  (swift-0.5.0)

### Fixed

• The Cursor hooks installed by semgrep mcp now track edited files separately for each Cursor conversation, so one window's stop scan no longer scans or discards another conversation's edits. (mcp-hook-cache-per-conversation)
• The semgrep mcp server's semgrep_scan tool now only scans files inside the client's workspace root, or the server's working directory when the client reports none. Set SEMGREP_MCP_ALLOW_SCAN_OUTSIDE_WORKSPACE=true to scan files outside it. (mcp-scan-workspace-roots)
• Interfile scans no longer fail with Failure: Failed to unmarshal cached value: Exception during parallelization: Exception.Timeout(...) when a taint configuration timeout fires at an unlucky moment. The timeout now only skips the affected rule and file, as intended. (CODE-9810)

2026.10.20 🐍

Parallel mode no longer prints an "experimental" banner, and sessions can check session.parallel to see if they run in a parallel worker. A new rattler backend uses py-rattler (install with the nox[rattler] extra), so you can request fast conda-style environments in a /// script block. Python versions read from classifiers now include free-threaded builds when the free-threading classifier is present, and are deduplicated. A single-argument @nox.parametrize now accepts ranges and other iterators, and the rattler backend loads config from the default locations. The GitHub Action now defaults to Python 3.11-3.15. This release also fixes several bugs in script mode, option handling, and tox-to-nox.

9.2.0

pytest 9.2.0 (2026-10-27)

Removals and backward incompatible breaking changes

• #14716: -c now raises a usage error for a path that does not exist, is a directory, or is in a format pytest has no loader for. Such paths were previously either ignored or reported as an unhandled FileNotFoundError.

• #8593: The indirect, ids and scope arguments of Metafunc.parametrize() <pytest.Metafunc.parametrize> -- and therefore of @pytest.mark.parametrize <pytest.mark.parametrize ref> -- are now keyword-only.

  Passing them positionally was a common source of confusing errors, e.g. parametrize("arg1", "arg2", [(1, 2)]) made the argvalues land in indirect and failed with indirect fixture '(1, 2)' doesn't exist; such mistakes now fail with an understandable TypeError. The type annotations have always declared these arguments as keyword-only.

• #993: Plugin import failures at startup are now reported and classified instead of escaping as a raw traceback with the accidental exit code 1:

  • a plugin that cannot be found -- via -p, pytest_plugins or PYTEST_PLUGINS -- exits with pytest.ExitCode USAGE_ERROR (4), like a conftest.py that fails to import;
  • a plugin that is found but raises while importing -- including a broken pytest11 entry point or a missing plugin dependency -- exits with pytest.ExitCode INTERNAL_ERROR (3), with the traceback preserved.

  pytest.main now returns these codes instead of raising ImportError. Also fixed an IndexError from pytest's own internals when the plugin raised an exception with no arguments.

Deprecations (removal in next major release)

• #14742: The private _pytest.python.CallSpec2 name has been renamed to CallSpec. The old CallSpec2 alias remains available for now and will be removed in pytest 10 or 11.

• #14755: Schedule yield_fixture decorator for removal in pytest 10 or 11.

• #14774: Similarly to the deprecation of class-scoped fixtures defined as instance methods in pytest 9.1, all higher-scoped fixtures (module, package, and session) defined as instance methods are now deprecated.

  They suffer from the same issue the original deprecation only fixed for class-scoped fixtures, see 10819 and 14011.

• #14808: Passing a non-string value to a string-typed ini option now emits a pytest.PytestRemovedIn10Warning. This affects [tool.pytest.ini_options] in pyproject.toml. In pytest 10 this will raise a TypeError, matching the behavior of the corresponding TOML config path.

• #7323: Passing bytes to TerminalReporter.write_line() is now deprecated, pass a str instead.

• #14743: Full diff: now contains a legend explaining the + & - symbols in diff output.
• #2781: When strict_markers is enabled, marker names used in -m expressions are now validated against registered markers.
• #6881: Added the parametrize_long_str_id_strategy configuration option to control how long str/bytes parameter values are handled in auto-generated test IDs. Explicit IDs set via ids=[...] or pytest.param(..., id=...) are not affected. Available strategies: short (default, values over 100 chars fall back to argname+index), sha256 (SHA-256 hex digest), legacy (keep full value), and disallow (error requesting explicit IDs).

Improvements in existing functionality

• #10745: A RecursionError whose recursion origin cannot be located now shows only the first and last 10 stack frames, matching what pytest already did when locating the origin failed outright. Previously the full traceback -- often around a thousand near-identical frames -- was rendered, which was both slow and unreadable. Pass --full-trace to see every frame.
