Version v0.2.0 of our pure Julia client for the [ClickHouse](https://clickhouse.tech/) native TCP protocol is out now!

This is the first release of the library where I’d say that it can now be called a functioning and practically useful client for the database.

## Significant changes

### Organizational

- The project was migrated from my private GitHub account over to the JuliaDatabases organization
- @waralex joined in as a second maintainer and contributed most of the changes that prompted the release of this second version of the client

### Technical

- As of writing, all ClickHouse column types are now supported, including fancier types such as `Array(T)` and `LowCardinality(T)`
- Enums and `LowCardinality(T)` types are now decoded using `CategoricalArray`s
- Greatly improved error handling and recovery
- ClickHouse `Date` types are now decoded as `Date` Julia types (previously, they were decoded to `DateTime`)
- Many smaller tweaks all over the codebase
