On behalf of the ocaml-lsp team, it is my pleasure to announce version 1.4.0. This release introduces support for automatic signature help. Signature help is not yet present in all possible contexts. We intend to improve to support as many relevant language constructs as possible in the future. Many thanks to @mnxn for implementing this feature.

The full change log is replicated at the end of this post for your convenience.

Happy Holidays!
