 - **Breaking:** On Web, `set_cursor_position` and `set_cursor_grab` will now always return an error.
 - **Breaking:** `PixelDelta` scroll events now return a `PhysicalPosition`.
 - On NetBSD, fixed crash due to incorrect detection of the main thread.
-- **Breaking:** The virtual key code `Subtract` has been renamed to `NumpadSubtract`.
 - **Breaking:** On X11, `-` key is mapped to the `Minus` virtual key code, instead of `Subtract`.
 - On macOS, fix inverted horizontal scroll.
 - **Breaking:** `current_monitor` now returns `Option<MonitorHandle>`.

 - On macOS, updated core-* dependencies and cocoa.
 - Bump `parking_lot` to 0.11
 - On Android, bump `ndk`, `ndk-sys` and `ndk-glue` to 0.2. Checkout the new ndk-glue main proc attribute.
+- **Breaking:** Prefixed virtual key codes `Add`, `Multiply`, `Divide`, `Decimal`, and `Subtract` with `Numpad`.
+- Added `Asterisk` and `Plus` virtual key codes.
