Changelog

Sourced from diesel's changelog.

[1.4.4] - 2020-03-22

Fixed

[1.4.3] - 2019-10-11

Fixed

• Updated several dependencies
• Fixed an issue where the postgresql backend exploits implementation defined behaviour
• Fixed issue where rustdoc failed to build the documentation
• diesel_derives and diesel_migrations are updated to syn 1.0

[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))
