Fixed an issue where rebuilding a primary key with duplicate entries could cause the server to stop unexpectedly. (Bug #37822992)
Fixed an issue related to dropping columns that were part of an index. (Bug #37726881)
Fixed an issue with indexing spatial datatype columns. (Bug #36682518)
Fixed an issue where creating a secondary index on a VARCHAR column could exceed configured memory limits, with the amount allocated being directly related to the value of innodb_ddl_buffer_size, leading to errors such as ERROR 1136 (21S01): Column count doesn’t match value count at row 1. (Bug #37233273)

New feature¶

PXC-4631: Percona XtraDB Cluster now prevents a node from automatically attempting a State Snapshot Transfer (SST) after a failed Incremental State Transfer (IST).

Bug fixes¶

PXC-4392: The issue was resolved by PXB-3470, which occurred when users had large databases containing compressed tables.
PXC-4644: Creating a foreign key (FK) without sufficient privileges causes a cluster inconsistency. The node where the command is executed fails with Error 1216 (Cannot add or drop foreign key constraint), while other nodes in the cluster that replicate the event fail with Error 1452 (Cannot add or update a child row: a foreign key constraint fails).

Build & packaging notes¶

The official packages were built with the WITH_LTO=ON flag to enable the Link-Time Optimization (LTO) feature.
