+* **kmcomapi:** Added the `MCompileForBaseKeyboard(long KLID)` COM method to the
+  new `IKeymanKeyboardInstalled2` interface, which extends
+  `IKeymanKeyboardInstalled`. The method accepts the user's base keyboard ID and
+  allows `mcompile` to compile all installed keyboard layouts against that
+  keyboard ID. See #16162 for details.
+* **kmcomapi:** Added the `Install3` COM method, which accepts a base keyboard
+  ID. The base keyboard ID is passed to `mcompile` during installation so that
+  the keyboard layout can be compiled against the specified base keyboard.
+  `Install3` has been added to the following interfaces: `IKeymanKeyboardFile3`,
+  `IKeymanPackageFile3`, `IKeymanKeyboardsInstalled3`, and
+  `IKeymanPackagesInstalled3`. See #16528 for details.
