ROW based replication active.
- pt-onine-schema-change --max-load paused if a status variable was
passed 0 as the value.
- pt-table-checksum reported a misleading error if a column comment
contained an apostrophe. For more information, see #1708749.
- In some cases, pt-table-checksum did not report that the same table
contained different values on the master and slave.

v3.0.4 released 2017-08-02
New Features
- Added collection of information about prepared statements by
pt-stalk when Performance Schema is enabled. For more information,

support AFTER triggers.

between JSON format and the default plain text.
- Added the --output-format=csv parameter for pt-archiver to archive
rows in CSV format.
- Added the --only-same-schema-fks option for pt-online-schema-change
to check foreigns keys only on tables with the same schema as the
original table. This should speed up the tool’s execution, but keep in

schemas, they won’t be detected. For more information, see #1690122.
- Added the --check-unique-key-change option for
pt-online-schema-change to abort if the specified statement for

ensure stale data is removed.
Bug fixes
- Fixed pt-table-checksum to support tables that have columns with
different collations or charsets. For more information, see

pt-online-schema-change.
- Fixed the --skip-check-slave-lag feature for pt-table-checksum to
safely check for undefined values.
