New Features

In contrast to the last release most changes in this release are minor or internal. We've added support for newer versions of some dependency crates (libsqlite-sys, uuid, ipnetwork).

Diesel CLI got a command line flag to check if a generated schema matches the already existing one. This is useful for CI setups to check there if the committed generated schema file matches the committed migrations.

We've added support for the diesel_mange_updated_at('table_name') SQL function on SQLite. This function handles the setup of an trigger that automatically updates the updated_at column on update operations.

Additionally several helpers were added to support the deserialisation of tuples and composite types on PostgreSQL.

As always, a full list of changes can be found it in the changelog

Thanks

[1.4.2] - 2019-03-19

Fixed

• Parenthesis are now inserted around all mathematical operations. This means that (2.into_sql() + 3) * 4 will correctly evaluate to 20 as expected. Previously we would generate SQL that evaluated to 14. This could even result in runtime errors if multiple types were involved (for example, interval * (integer + 1))

[1.4.1] - 2019-01-24

Fixed
