+# v0.4.0
+
+## Added
+- Lookup expressions
+- With the language server, hovering over a diagnostic message now shows any
+  associated hints.
+
+## Changed
+- The compiler now uses .typelib files rather than XML .gir files, which reduces
+  dependencies and should reduce compile times by about half a second.
+
+## Fixed
+- Fix the decompiler/porting tool not importing the Adw namespace when needed
+- Fix a crash when trying to compile an empty file
+- Fix parsing of number tokens
+- Fix a bug where action widgets did not work in templates
+- Fix a crash in the language server that occurred when a `using` statement had
+no version
+- If a compiler bug is reported, the process now exits with a non-zero code
