Bug Fixes

v3.0.5 released 2017-11-20

New Features
- Improve MongoDB Profiler for PMM and PT
- The mongodb-query-digest supports MongoDB versions lower than 3.2;
  incorrect output was fixed.
- The pt-summary, pt-mysql-summary, pt-mongodb-summary commands
  provide output in the the JSON format.
- pt-mysql-summary shows the output of the Show Slave Hosts command.
- pt-table-sync supports replication channels (requires MySQL version
  5.7.6 or higher)

Bug fixes
- pt-mext fails if the Rsa_public_key variable is empty.
- pt-mongodb-query-digest --version produced incorrect values.
- pt-online-schema-change incorrectly processed virtual columns.
- pt-online-schema-change command reported an error when the name of
  an index contained ‘unique’ as as the prefix or suffix.
- pt-table-checksum did not detect differences on a system with the
  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.
- pt-online-schema-change --alter could fail if field names contained
  upper case characters. For more information, see #1705998.
- In some cases pt-mongodb-query-digest could not connect to a db
  using authentication.
- In some cases, pt-kill could ignore the value of the --busy-time
  parameter. For more information, see #1016272.

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.
- Added --output-format option for pt-mongodb-summary to choose
  between JSON format and the default plain text.
- Added the --output-format=csv parameter for pt-archiver to archive
  rows in CSV format.

  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
  mind that if you have foreign keys referencing tables in other
  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
--alter is trying to add a unique index. This is supposed to avoid
  adding duplicate keys that might lead to silently losing data.
- Added the --truncate-replicate-table option for pt-table-checksum to
  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
  #1674266.
- Fixed primary key handling by pt-archiver. For more information, see
  #1691630.

  decimal.

  pt-online-schema-change.

  safely check for undefined values.
