+We've also fixed a number of small inconsistencies and crashes in the indexer, making it more robust and accurate. I especially want to call out the fix that @lukad made, that improved indexing performance by 3600x on his large codebase. 
+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.
