v2.10

• Support syncing from a MySQL database to a specific named schema on PostgreSQL, vice versa, or between two PostgreSQL schemas.

v2.9

• Don't throw errors when syncing MySQL -> MySQL and tinyint(1) columns have non-boolean values (though note MySQL has deprecated integer display widths for anything except boolean columns). tinyint(1) columns will however continue to be interpreted as boolean when syncing MySQL -> PostgreSQL.

v2.8

• When syncing from MySQL/MariaDB to PostgreSQL, add a suffix number to indexes to make them unique across the schema if there are any conflicts.

v2.7

• Create keys before dropping keys when possible, in case they're in use for an FKC.
• Performance optimisation: allocate heap memory less for small objects in keys.

v2.6

• Add --version option. Thanks @proby.
• Revert 2.0 change 'Optimise inserts on MySQL/MariaDB by turning off unique_key_checks while syncing', suspected as the cause of a replication problem user field report.

v2.5

• Support MySQL/MariaDB's nonstandard FLOAT(M,D) and DOUBLE(M,D) syntax.

v2.4

• Draft support for multiple schemas on PostgreSQL, including syncing tables that have the same name in multiple schemas, and creating them in the appropriate schema.
• Fix resetting sequences on PostgreSQL tables that need quoting.

v2.3

• Support specifying the SSH port using --via servername:port syntax.
• Fix incompatibility with v1 'from' ends when using multiple workers.
• Work around compatibility problem when using the MySQL client library with MariaDB servers, causing problems determining schema defaults etc.

v2.2

• Fix regression in LONGBLOB/MEDIUMBLOB support for MySQL & MariaDB.

v2.1

• New default hash algorithm BLAKE3, giving a significant performance improvement, particularly on CPUs supporting AVX2 and above.
• Update ruby test suite to run on ruby 2.7.0. Thanks @proby.
