+## Added Go 1.24 support
+
+This release adds support for Go 1.24.
+
+## Checks
+
+### Changed checks
+
+The following checks have been improved:
+
+- {{< check "U1000" >}} treats all fields in a struct as used if the struct has
+  a field of type `structs.HostLayout`.
+- {{< check "S1009" >}} now emits a clearer message.
+- {{< check "S1008" >}} no longer recommends simplifying branches that contain
+  comments ({{< issue "704" >}}, {{< issue "1488" >}}).
+- {{< check "S1009" >}} now flags another redundant nil check ({{< issue "1605" >}}).
+- {{< check "QF1002" >}} now emits a valid automatic fix for switches that use
+  initialization statements ({{< issue "1613" >}}).
