This release includes the following changes:

New Features:
  • PT-1571: Improved hostname recognition in pt-secure-collect
  • PT-1569: Disabled --alter-foreign-keys-method=drop_swap in pt-online-schema-change
  • PT-242: (pt-stalk) Include SHOW SLAVE STATUS on MySQL 5.7 (Thanks Marcelo Altmann)
Fixed bugs:
  • PT-1570: pt-archiver fails to detect columns with the word *GENERATED* as part of the comment
  • PT-1563: pt-show-grantsfails for MySQL 5.6 producing an error which reports that an unknown column account_locked has been detected.
  • PT-1551: pt-table-checksum fails on MySQL 8.0.11
  • PT-241: (pt-stalk) Slave queries don’t run on MySQL 5.7 because the FQDN was missing (Thanks Marcelo Altmann)
Breaking changes:


Starting with this version, the queries checksum in pt-query-digest will use the full MD5 field as a CHAR(32) field instead of storing just the least significant bytes of the checksum as a BIGINT field. The reason for this change is that storing only the least significant bytes as a BIGINT was producing inconsistent results in MySQL 8 compared to MySQL 5.6+. pt-online-schema-change in MySQL 8:


Due to a bug in MySQL 8.0+, it is not possible to use the drop_swap method to rebuild constraints because renaming a table will result in losing the foreign keys. You must specify a different method explicitly.
