-## Unreleased 
+## v0.6.0 `24 April, 2024`
+After multiple people asked, both document and workspace symbols have been implemented. 
+Both make heavy use of our indexing infrastructure, which provides extremely fast and 
+accurate results.
+
+We've also fixed a number of small inconsistencies and crashes in the indexer, making it more robust and accurate. When you update to this release, we strongly recommend re-indexing your project's source code by opening the project's `mix.exs` file and 
+running the `Rebuild <your project>'s code search index` code action.
+
+In addition, we've improved support for completions in phoenix controllers, stopped completions inside strings and have changed how we sort completions. The new sorting scheme is a big improvement for usability, and sorts things by how "close" they are to what you're working on. Give it a shot, we think you'll like it. 
+
+I'd like to thank all our new contributors, and especially our core team of 
+@scottming, @zachallaun, @moosieus and @blond. You've all gone above and beyond.
