Sourced from diesel's changelog.

[2.2.1] 2024-06-12

Fixed

• Fixed using #[dsl::auto_type] with functions that accept reference arguments
• Fixed using #[derive(Queryable)] with structs that use a type named Row as field type
• Fixed a regression that prevented using mysqlclient-sys 0.2.x with diesel 2.2
• Fixed connecting to postgres database using the scram-sha-256 authentication method on windows while using the bundled postgres builds
• Improved the error messages in diesel-cli for cases where a file/folder was not found
• Fixed several version detection bugs in mysqlclient-sys to use pre-generated bindings in more situations

[2.2.0] 2024-05-31

Added

• Support [print_schema] except_custom_type_definitions = ["Vector"]. If a custom type matches one element on the list it's skipped.
• Added automatic usage of all sqlite rowid aliases when no explicit primary key is defined for print-schema
• Added a #[dsl::auto_type] attribute macro, allowing to infer type of query fragment functions
• Added the same type inference on Selectable derives, which allows skipping specifying select_expression_type most of the time, in turn enabling most queries to be written using just a Selectable derive.
• Added an optional #[diesel(skip_insertion)] field attribute to the Insertable derive macro, allowing fields which map to generated columns to be skipped during insertion.
• Support for connection instrumentation. This allows to inspect any query run by your application
• Logging in diesel-cli
• Support for libsqlite3-sys 0.28
• Add sqlite-integer-primary-key-is-bigint configuration option, usable with SQLite 3.37 or above, allowing to use BigInt for INTEGER PRIMARY KEY columns in SQLite for tables without the WITHOUT ROWID attribute (SQLite doc).
• Support for multiple print_schema entry in diesel.toml (e.g. [print_schema.user1]), which allows generating multiple schema.rs files
• Add support for COPY TO and COPY FROM statements
• Add support for mapping chrono::Duration to postgresql's INTERVAL sql type
• Added serialize_database_to_buffer and deserialize_readonly_database_from_buffer methods in SqliteConnection to support serialization/deserialization of SQLite databases to and from byte buffers.
• Added SerializedDatabase wrapper type for a serialized database that is dynamically allocated by calling serialize_database_to_buffer. This RAII wrapper deallocates the memory when it goes out of scope with sqlite3_free.

Changed

• The minimal officially supported rustc version is now 1.78.0
• Deprecated sql_function! in favour of define_sql_function! which provides compatibility with #[dsl::auto_type]
• Deserialization error messages now contain information about the field that failed to deserialize

[2.1.6] 2024-04-19

• Fix using BoxableExpression with having clauses
• Fix using numeric expressions with aliased fields
• Minor documentation fixes

[2.1.5] 2024-03-15

• Fix impl SqlOrd postgres > postgres_backend feature flag.
• Allow Queryable to be used with multiple table names.
• Fix an inconsistent unit test
• Fix a clippy lint
• Fix ./bin/test feature flag calls.
• Update libsqlite3-sys to allow version 0.28 as well
