Sourced from diesel's changelog.

[2.1.1] 2023-08-xx

Fixed

• Fixed an issue in diesel-cli that lead to using unquoted table names in one of the internal queries
• Fixed a bug in diesel print-schema that lead to generating invalid table! macros if both the #[sql_name] and the #[max_lenght] attribute are present
• Fixed an issue in diesel-cli that lead to ignoring certain foreign key constraints for postgresql
• Fixed an crash while using diesel print-schema with really old sqlite versions
• Fixed an issue where #[diesel(check_for_backend)] ignored #[diesel(deserialize_as)] attributes
• Fixed several issues with the new #[derive(MultiConnection)] feature
• Fixed some edge cases in our sqlite timestamp parsing behaviour
• diesel migration generate --diff-schema now respects table filters as setup for print-schema via diesel.toml
• Fixed a potential breaking change around queries containing DISTINCT ON and ORDER BY clauses consisting of custom sql expressions (e.g. diesel::dsl::sql)

Added

• Support for bigdecimal 0.4

[2.1.0] 2023-05-26

Changed

• The minimal officially supported rustc version is now 1.65.0

Added

• Added the custom_type_derives config option to customize the derives for SQL type definitions automatically generated by Diesel CLI.
• Add a #[derive(MultiConnection)] proc-macro that lets you easily implement diesel::Connection for an enum of connections to different database backends.
• Added a --diff-schema flag to the diesel migration generate command that generates a migration based on the difference between your database and the provided schema.rs file
• Add a ON CONFLICT (...) DO UPDATE ... [WHERE ...] conditional clause support for PostgreSQL.
• Add support for MySQL's ON DUPLICATE KEY DO UPDATE syntax through the existing upsert functions.
• Add ability to define multiple columns in a single distinct_on for PostgreSQL, like: .distinct_on((column_a, column_b)).
• Added column size restrictions to the generated schema.rs file

[2.0.4] 2023-04-18

Fixed

• Workaround the missing name resolution in rust-analyzer. This should fix type inference for some diesel queries. (It remains broken for queries containing .filter()/.inner_join()/.left_join(). These require fixes in rust-analyzer itself)
• Fixed a bug that could lead to inserting null values instead of empty values for custom sqlite types
• Fixed a bug that could lead to an unexpected panic while providing an out of bounds bind for sql_query in the sqlite backend
• Fixed some mysql backend specific impl being behind the mysql instead of the mysql_backend feature flag

Added
