## Ecosystem

The setup-regal GitHub Action has been promoted to v1. This fixes the

v0.16.0
-------
This release adds 2 new linter rules and a language server protocol
(LSP) implementation to Regal.

- New rule: `duplicate-rule`
- New rule: `use-rego-v1`

## New feature: Regal language server

The Language Server Protocol (LSP) provides a way for editors to
integrate support for various programming languages using a common
protocol. Using an LSP server implementation rather than one built
specifically for a single editor allows the same code to be used across
all editors with LSP support. v0.16.0 brings a language server mode to
Regal, allowing diagnostics (i.e. linting) of Rego to be performed
continuously in a workspace rather than as a one-off CLI operation.
This is the first step towards bringing Regal into editors like VS
Code, and having linting of Rego natively supported as you work with
your policies. Expect to see more in this space soon!
