Changelog #26

Commit: fbb8b88
Release: 2020-05-25

In the effort to improve support for all editors, and to speedup acceptance of rust-analyzer extensions to the Language Server Protocol, all extensions are now documented:

If you maintain rust-analyzer plugin for some editor, consider implementing these extensions and giving feedback for the corresponding upstream issue at Microsoft/language-server-protocol. Additionally, consider subscribing to #4604, which will announce all future extensions and changes. Note that we don’t have any compatibility guarantees yet — all our extensions are subject to change on a short notice.

Sponsors

Starting this week, we’ll be mentioning our significant Open Collective backers of "Sponsor" level or higher in the changelogs.

This week, we welcome a new sponsor: Prisma, a modern database toolkit for Node.js and TypeScript built with Rust under the hood.
