Release diesel 1.4.6

* Fixed a use-after-free issue in the `QueryableByName` implementation
  of our `Sqlite` backend
* Updated several dependencies

Release diesel 1.4.4

    This release updates several public dependencies and fixes a minor
    issue with printing embeded migrations.

    The following dependencies where updated to newer versions:

    * `libsqlite3-sys` to allow versions up to 0.17.x
    * `uuid` to allow versions up to `0.8.x` (with the `uuidv7` feature)
    * `ipnetwork` to allow versions up to `0.16.x` (with the
    `network-address` or `extras` feature)

    Also release migration_macros 1.4.2 and migrations_internals 1.4.1

1.4.3

* 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

Release v1.4.2

This is a minor bug fix release. Diesel now inserts parenthesis around
all mathematical operations, to preserve the order of operations given
by Rust, particularly if the user had used parenthesis. This means that
`(2.into_sql() + 3) * 4` will now generate SQL which evaluates to 20
instead of 14.

1.4.1

This release fixes a minor memory safety issue in SQLite. This bug would only occur in an error handling branch that should never occur in practice.

Release diesel 1.4.0

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, for a full list of changes you can find it in [the changelog](https://github.com/diesel-rs/diesel/blob/v1.4.0/CHANGELOG.md)

Release v1.3.3

This is a small bugfix release, addressing an issue with MySQL 8.0. The
behavior of the C API in libmysqlclient changed in this version of
MySQL, causing problems when a connection pool was used with Diesel.

If you are not using MySQL, or are on a version older than 8.0, this
release does not affect you.

Release v1.3.2

This release includes several bug fixes. This release only affects users
of unsigned types on MySQL, or users whose code failed to compile with
1.3.1.
