 # IACore (Independent Architecture Core)
 
+> [!WARNING]
+> A major rewrite is coming to IACore API and coding style on Jan 30th. While the functionality and classes you're familiar will remain the same, this rewrite will introduce breaking changes to the overall API and how IACore is used. This rewrite will align IACore API and coding style with a Rust-inspired modern, clean and a vastly improved maintainable alternative.
