* Fine-grained inplace skipping by INNOBASE_ALTER_VERSIONED_REBUILD; * Fixed column WITHOUT SYSTEM VERSIONING + ADD COLUMN; * Fixed instant field change (MDEV-16330); * Revisited test versioning.online; * Merged the test versioning.trx_id_versioning_attribute_persistence to versioning.online; * Renamed some versioning functions: ** change_fields_versioning_cache() -> vers_change_fields_cache() ** change_field_versioning_try() -> vers_change_field_try() Skip condition moved out of func. Closes tempesta-tech/mariadb#414 Closes tempesta-tech/mariadb#540 Related to tempesta-tech/mariadb#281
