Protobuf now has full LSP support

Buf is proud to announce the first fully-featured, spec-compliant LSP server for Protobuf. The Language Server Protocol is the standard API for integrating language support into your favorite IDE or text editor, such as VSCode, IntelliJ, or Neovim. An LSP server provides the smarts that power go to definition, code completion, finding references, and semantics-aware syntax highlighting.

Protovalidate is now v1.0

After two years of development, we're proud to announce that Protovalidate has reached v1.0. Protovalidate is the semantic validation library for Protobuf. Protobuf gives you the structure of your data, but Protovalidate ensures the quality of your data. Without semantic validation, you're stuck writing the same validation logic over and over again across every service that consumes your messages. With Protovalidate, you define your validation rules once, directly on your schemas, and they're enforced everywhere.

Protobuf Editions are here: don’t panic

Most Protobuf users should ignore Editions and continue using proto3. If you become an early adopter, we’ve been working closely with Google to ensure that Buf will support editions as soon as they’re generally available.
