[25.4.4] - 2025-11-12 Fixes - Fixed a bug where the raft snapshot would sometimes contain incorrect term which would result in an unrecoverable failure of the receiving instance. - Resolve hang when using TLS (hang in `ssl_iostream_destroy` when fiber is cancelled). - Resolve hang when using TLS (fix infinite loop in coio_writev_timeout on SSL_ERROR_ZERO_RETURN). - DML to global tables no longer will fail with errors such as "Compacted" (See also https://git.picodata.io/core/picodata/-/issues/2273). - Fix trigger execution and privilege initialization for scram-sha256 auth in pgproto. SQL - Add IF NOT EXISTS support for ALTER TABLE ADD COLUMN. Observability - Added metrics `pico_sql_global_dml_query` and `pico_sql_global_dml_query_retries` which report respectively the total number of SQL DML operations on global tables and number of times these operations had to be retried due to CAS conflicts.
