I am pleased to announce a new release of Merlin!

Merlin is an editor service that provides modern IDE features for OCaml.

This new release brings a number of improvements and bug fixes. In particular we identified and patched an important memory consumption issue that could greatly affect Merlin’s performance in heavily functorized projects.
