## Bugs Fixed

* [CONJ-1320](https://jira.mariadb.org/browse/CONJ-1320) - PAM (dialog) authentication now requires 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-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-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-1259](https://jira.mariadb.org/browse/CONJ-1259) - `DatabaseMetaData` read-only detection: handle MariaDB 12.0 `@@read_only` returning `ON`/`OFF` instead of `1`/`0`
