+# Upgrading from 6.x to 7.x

+Upgrading from v6 should be straightforward.

+
+## Scala 3 support
+
+This release brings Scala 3 support.
+
+### Syntactic changes
+
+If you use Scala 3, you might need to change slightly some of your glue code:
+- parenthesis are now necessary even around a single-argument step or hook definition
+```scala
+// Won't compile anymore
+Given("Something {}") { str: String =>
+    // ...
+}
+
+// Instead use:
+Given("Something {}") { (str: String) =>
+  // ...
+}
+```
+- hooks must explicitly return `Unit` (most of the time you already had compile errors with such statements in Scala 2.x as well)
+```scala
+Before {
+  // ... // Some code not retuning Unit
+  () // Explicit Unit
+}
+```
+
+### Other changes
+
+The line numbers provided in reports might slightly change
+from start of a step definition to end of a step definition in some cases.
+In case of errors, these line numbers should be more accurate than before.
