What’s Changed

This release brings about several great new additions including:
- dbt 1.0.0 compatibility.
- CLI and Simple API parameters to provide custom paths to config files.
- Refinement to Simple API to return parse output in JSON format rather than as an internal SQLFluff object (**BREAKING CHANGE**).
- An [Official SQLFluff Docker Image](https://hub.docker.com/r/sqlfluff/sqlfluff).
- Grammar improvements across various dialects.
- A new rule (L057) to check for non-alphanumeric values in identifiers.

There have also been many bug fixes and improvements to the CI and development processes.

What’s Changed

One of the biggest new features in this release is the support for SQLAlchemy and other "placeholder" templating within SQL queries. Check out [the documentation on how to set it up](https://docs.sqlfluff.com/en/latest/configuration.html#placeholder-templating).

This release also adds **seven** new rules. Get some help with your leading whitespace, semi-colon placement, inconsistent column references in `GROUP BY/ORDER BY`, and getting rid of `RIGHT JOIN`'s among other useful lints with our new rules! See our [rules documentation](https://docs.sqlfluff.com/en/stable/rules.html) for more details.

On top of those, we have made loads of grammar improvements across many dialects, improvements to the dbt templater (including issues where `sqlfluff fix` would corrupt the code :scream:), more fix routines, and lots more improvements.
