asyncpg v0.32.0
## Improvements
* Support Python 3.15 (#1367, #1378)
(by @elprans in 1b11846 and 58c0c59)
* Support PostgreSQL 19 (#1379)
(by @elprans in 8d2a5ae)
* 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`.

* Use `hashlib.pbkdf2_hmac()` for faster SCRAM password derivation (#1359)
(by @twelfthlabor in 00319a9)
* Use the statement cache for `copy_records_to_table()` introspection (#1360)
(by @matemax in dd05865)
## 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 4a83cc2)
* Honor `Connection.close(timeout=...)` while waiting for a pending
cancellation (#1361)
(by @gyanu2507 in c06bcb4)
* Prevent stuck cancellation from blocking connection teardown or pool release
by bounding cancellation with the command or release timeout (#1370)
(by @elprans in 4cf0220)
* Preserve the server error when the connection closes mid-operation (#1369)
(by @RitiGrover in 6c8f1a7)
* Fix COPY cleanup when a records generator raises, preserving the original
exception and avoiding protocol desynchronization and stalled rollback (#1358)
(by @CodingCossack in fdc6bc8)
* Reparse unnamed statements before cursor binding when the statement cache
is disabled (#1364)
(by @elprans in 302ba49)
* Allow cursors in transactions started outside `Connection.transaction()`,
such as with an explicit `BEGIN` (#1350)
(by @aryansk in 25aaaf5)
* Remove the query logger when the `query_logger()` block raises (#1373)
(by @kratos0718 in 6a7fbd3)
* Fix a segfault in `Record.get()` with an invalid number of positional
arguments (#1333)
(by @apoorvdarshan in 40a3832)
* Align SSL startup retries with libpq and improve SSL rejection diagnostics
(#1366). Retry alternative transports only before authentication succeeds.
Direct TLS now requires `sslmode=require`, `verify-ca`, or `verify-full`,
or an explicit `SSLContext`.
(by @elprans in 78752c9)
* Preserve password errors during SSL fallback when the fallback fails with
a less specific authorization error (#1331)
(by @Mauricio0129 in 2d97947)
* Handle cleartext password authentication when no password is supplied
without raising an `AttributeError` (#1351)
(by @aryansk in 6be5915)
* Set the `postgresql` ALPN protocol on SSL contexts created by asyncpg so
direct TLS connections work with PostgreSQL 17 and later (#1372).
User-provided contexts must set this protocol for direct TLS connections.
(by @DurandA in b21325d)
* Link explicitly against `libm` on non-Windows platforms to fix undefined
math symbol errors when loading the extensions (#1305)
(by @veeceey in db8ecc2)
* Fix builds on FreeBSD 15 by linking against `libstdthreads` (#1368)
(by @elprans in 87bcaf9)
## Other
* Replace `pkg_resources` with `packaging` in `setup.py` (#1362)
(by @elprans in 6695db7)
* Build Linux and macOS ARM64 wheels on native runners and add Windows ARM64
wheel builds (#1308)
(by @ddelange in 1e8cc1c)
* Add manual and PR-label-triggered dry runs to the release workflow (#1374)
(by @elprans in 1bd643e)
* Clarify how `execute()` uses prepared statements and how to confirm an
`INSERT` in the documentation (#1336)
(by @pctablet505 in cdf816c)
* Fix typos in comments and docstrings (#1332)
