0.7.0

0.7.0 is a fairly small release in terms of new features, with lots of internal improvements, such as integration tests with a whole range of DBs, a blog post on Pi day, RFCs for a type system, and more robust language bindings. Our April 2023 update is attached below.

There's a very small breaking change to the rust API, hence the minor version bump.

The release has 131 commits from 10 contributors. Particular credit goes to to @eitsupi & @Jelenkee, who have made significant contributions, and @vanillajonathan, whose prolific contribution include our growing language bindings.

A small selection of the changes:

Features:

• prqlc compile adds --color & --include-signature-comment options. (@max-sixty, #2267)

Web:

• Added the PRQL snippets from the book to the Playground (@Jelenkee, #2197)

Internal changes:

• Breaking: The compile function's Options now includes a color member, which determines whether error messages use ANSI color codes. This is technically a breaking change to the API. (@max-sixty, #2251)
• The Error struct now exposes the MessageKind enum. (@vanillajonathan, #2307)
• Integration tests run in CI with DuckDB, SQLite, PostgreSQL, MySQL and SQL Server (@Jelenkee, #2286)

New Contributors:

• @k-nut, with #2294

April 2023 update

PRQL is being actively developed by a growing community. It's ready to use by the intrepid, either as part of one of our supported extensions, or within your own tools, using one of our supported language bindings.

PRQL still has some minor bugs and some missing features, and probably is only ready to be rolled out to non-technical teams for fairly simple queries.

Here's our current Roadmap and our Milestones.

Our immediate focus for the code is on:

• Building out the next few big features, including types and
  modules.
• Ensuring our supported features feel extremely robust; resolving any priority bugs.

We're also spending time thinking about:

• Making it really easy to start using PRQL. We're doing that by building integrations with tools that folks already use; for example our VS Code extension & Jupyter integration. If there are tools you're familiar with that you think would be open to integrating with PRQL, please let us know in an issue.
• Making it easier to contribute to the compiler. We have a wide group of contributors to the project, but contributions to the compiler itself are quite concentrated. We're keen to expand this; #1840 for feedback.
