-# HEADS UP: BIG RESTRUCTURING UNDERWAY

-The Svelte repo is currently in the process of heavy restructuring for Svelte 4. After that, work on Svelte 5 will likely change a lot in the compiler as well. For that reason, please don't open PRs that are large in scope, touch more than a couple of files, etc. In other words, bug fixes are fine, but feature PRs will likely not be merged.
