+
+Inspired by Elm's
+[Compiler Errors for Humans](https://elm-lang.org/news/compiler-errors-for-humans) and
+[Compilers as Assistants](https://elm-lang.org/news/compilers-as-assistants),
+we recently took a step back and reworked *every* error message in the Flix compiler.
+
+Here is what you can look forward to in the next version of Flix:
+
+All error messages now have **semantic** syntax highlighting. For single-line errors:
+![unexpected argument](unexpected-argument.png)
+
+And for multi-line errors:
+![mismatched types](mismatched-types.png)
+
+Simple errors are kept brief:
+![duplicate annotation](duplicate-annotation.png)
+
+Whereas complex errors come with explanations and examples:
+![missing implementation](missing-implementation.png)
+
+And, when possible, with suggestions for a fix:
+![constructor not found](constructor-not-found.png)
+
+For very complex errors, we now give an in-depth technical explanation:
+![complex instance](complex-instance.png)
+
+---
+
+That's all for now.
+
+Hope you enjoy our new colors!
