 ### Experimental
 
-* None.
+* SwiftLint can now be built and run on Windows. It is expected to work in the same way as
+  on other platforms. The only restrictions are missing support for `?[]` glob patterns in
+  include/exclude patterns and the requirement for `\n` as line ending in all linted files.
