+## Staticcheck 2022.1.2 release notes {#2022.1.2}
+
+This release addresses the following false positives, crashes, infinite loops, and performance issues:
+
+- For certain packages that contain tens of thousands of types and methods, such as those generated by
+  [ygot](https://github.com/openconfig/ygot), Staticcheck now finishes [much
+  faster](https://github.com/openconfig/featureprofiles/pull/181#issuecomment-1119250596).
+- Several infinite loops when handling recursive type parameters have been fixed
+- {{< check "S1009" >}} no longer mistakes user-defined functions named `len` for the builtin ({{< issue "1181" >}})
+- {{< check "ST1015" >}} no longer reorders `switch` statements if their order is significant due to the use of `fallthrough` ({{< issue "1188" >}})
+- {{< check "SA1013" >}} now detects constants more robustly, avoiding both false negatives and false positives.
+  Furthermore, it makes sure that offending methods implement io.Seeker and doesn't just rely on the name `Seek` ({{< issue "1213" >}}).
+- {{< check "SA5008" >}} now understands more third-party extensions to `json` struct tags
+- A crash involving functions named `_` has been fixed ({{< issue "1268" >}})
+- A crash involving slicing type parameters of type `string | []byte` has been fixed ({{< issue "1270" >}})
+- {{< check "SA1019" >}} now handles imports of deprecated standard library packages in the same way it handles other
+  deprecated API, taking the targeted Go version into consideration ({{< issue "1117" >}})
+
+Additionally it is strongly recommended to use Go 1.18.2 for building Staticcheck, as it fixes further generics-related
+bugs in the type checker.
