Percona XtraDB Cluster 9.7.2-2 has been released

Percona XtraDB Cluster 9.7.2-2 has been released on November 2, 2026.

Try it out using the Quickstart guide.

A note on MySQL 9.7.3

After a thorough review of the updates included in MySQL 9.7.3, Percona has decided not to release a corresponding Percona Server for MySQL 9.7.3. MySQL 9.7.3 is a Critical Security Patch Update (CSPU) — a targeted security release that Oracle can issue between quarterly Critical Patch Updates (CPUs) when needed. The fixes included in this CSPU do not affect Percona Server for MySQL.

This release is based on Percona Server for MySQL 9.7.2-2.

Percona Server for MySQL 9.7.2-2

Percona Server for MySQL 9.7.2-2 introduces the following new features and improvements:

  • Adds OpenID Connect (OIDC) authentication. Users can authenticate through compatible external identity providers. The server validates JSON Web Tokens (JWTs) and audience claims, maps identity-provider groups to MySQL roles, and supports proxy users. The OIDC plugin also includes telemetry and memory instrumentation to improve monitoring and operational visibility. Find more information in OpenID Connect authentication and in Get started with OpenID Connect authentication.
  • Adds the DISTANCE() function, and the VECTOR_DISTANCE() alias, for calculating the distance between vector values. Supported metrics are EUCLIDEAN, EUCLIDEAN_SQUARED, MANHATTAN, COSINE, and DOT. Applications can use these functions to measure vector similarity and support search, recommendation, and other vector-based workloads. See DISTANCE().

Improvements

  • PXC-5106: Sets sql_require_primary_key=1 when using pxc_strict_mode=ENFORCING or MASTER.
  • PXC-5208: Adds the repl.force_sst_after_inconsistency option. When enabled, a node voted out of the cluster because of a data inconsistency removes grastate.dat, so the next start uses a full State Snapshot Transfer (SST) instead of Incremental State Transfer (IST).

Bug fixes

  • PXC-5252: Fixed an issue where clone State Snapshot Transfer (SST) failed when the validate_password component was enabled with a strict policy, because the generated password for mysql.pxc.sst.user did not meet the configured requirements.
  • PXC-5291: Fixed an issue where a user with only the SET_ANY_DEFINER privilege could create a trigger when log_bin_trust_function_creators=0.
