## Key Enhancements
* [CONJ-1223](https://jira.mariadb.org/browse/CONJ-1223) - Cache TLS trust/key managers across connections to reduce SSL connection cost
* [CONJ-1314](https://jira.mariadb.org/browse/CONJ-1314) - Add SPI for interactive dialog (PAM) authentication callback
* [CONJ-1311](https://jira.mariadb.org/browse/CONJ-1311) - Add dedicated option `useIpForKillQuery` for query cancellation
* [CONJ-1310](https://jira.mariadb.org/browse/CONJ-1310) - Add full native-image (GraalVM) support and CI coverage
## Bugs Fixed
* [CONJ-1320](https://jira.mariadb.org/browse/CONJ-1320) - PAM (dialog) authentication must require a secure connection (TLS or unix socket), like `mysql_clear_password`
* [CONJ-1319](https://jira.mariadb.org/browse/CONJ-1319) - Use constant-time comparison when validating the server certificate fingerprint
* [CONJ-1318](https://jira.mariadb.org/browse/CONJ-1318) - Enforce `allowLocalInfile=false` on the server's local-infile request, so a malicious server cannot read a client file despite the option being disabled
* [CONJ-1322](https://jira.mariadb.org/browse/CONJ-1322) - Match `LOAD LOCAL INFILE` filename case-sensitively
* [CONJ-1323](https://jira.mariadb.org/browse/CONJ-1323) - `LOAD LOCAL INFILE` validation rejects statements preceded by line comments
* [CONJ-1324](https://jira.mariadb.org/browse/CONJ-1324) - Fix SQL parser to correctly handle `--` in expressions and reset `lastChar` after block comments
* [CONJ-1315](https://jira.mariadb.org/browse/CONJ-1315) - Cap `BigDecimal`/`BigInteger` string parsing length to prevent CPU exhaustion in case of a man-in-the-middle
* [CONJ-1317](https://jira.mariadb.org/browse/CONJ-1317) - Ensure a non-UTF-8 character set cannot be used for protocol exchanges
* [CONJ-1316](https://jira.mariadb.org/browse/CONJ-1316) - Pin `Locale.ROOT` on locale-sensitive call sites and date/time/Duration text formatting (fixes locale-dependent parsing/formatting, e.g. under `tr_TR`)
* [CONJ-1304](https://jira.mariadb.org/browse/CONJ-1304) - Read `CallableStatement` parameter metadata from `mysql.proc`, with MySQL `information_schema` fallback
* [CONJ-1299](https://jira.mariadb.org/browse/CONJ-1299) - Keep `VALUES` literals after the last placeholder when rewriting batches
* [CONJ-1313](https://jira.mariadb.org/browse/CONJ-1313) - Race condition in `HaMode#getAvailableHostInOrder` can cause a `NullPointerException`
* [CONJ-1311](https://jira.mariadb.org/browse/CONJ-1311) - `Connection.cancelCurrentQuery` fails with `SslMode.VERIFY_FULL` when the client socket IP is set
* [CONJ-1264](https://jira.mariadb.org/browse/CONJ-1264) - Handle `LocalDateTime` as a zoneless wall-clock value
