[/LIST]Fixed bugs:  
[LIST]

[\*][PT-241](https://jira.percona.com/browse/PT-241): (pt-stalk) Slave queries don’t run on MySQL 5.7 because the FQDN was missing (Thanks [Marcelo Altmann](https://www.percona.com/blog/author/marcelo-altmann/))  
[/LIST]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+](https://bugs.mysql.com/bug.php?id=89441), 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.
