⚡ Performance & 0.0% Idle CPU

• Event-Driven Message Pump: Replaced busy polling loops with message queue draining and MsgWaitForMultipleObjectsEx, dropping background idle CPU usage to 0.0%.
• Zero-Allocation Packet Serialization: Replaced dynamic string streams with stack buffers and std::string_view across all UDP broadcasting hot paths.
• Hardware Dirty-Checking: Integrated dwPacketNumber and memcmp dirty checks across controller loops to skip packet generation and socket transmission when inputs are resting.
• 1.0 ms Multimedia Timer Precision: Locked multimedia timer resolution to 1.0 ms via timeBeginPeriod(1).

⌨️ Keyboard & Protocol Enhancements

• Numpad Enter Differentiation: Detects the KF_EXTENDED flag on VK_RETURN to remap Numpad Enter to synthetic VK code 14 (0x0E), aligning with Warudo's NUMPAD_RETURN key binding.
• Defensive Modifier Aliasing: Added automatic bidirectional mapping between generic modifiers (VK_SHIFT, VK_CONTROL, VK_MENU) and their left/right counterparts.
• POD DLL Shared Segments: Standardized KeyboardTracker.dll shared data segment to raw POD arrays for robust multi-process memory isolation.

🎮 Controller & Pointer Improvements

• XInput Initial State: Fixed controller connection lifecycle to immediately broadcast the resting state upon connection, preventing uninitialized states in receivers.
• Mouse Click Freshness: Updated MouseTracker.dll hook callback to refresh coordinates and extra info on all button-down and button-up events.
• GameInput Status: GameInput controller mode is now marked as (Experimental). For standard Xbox controllers, XInput is recommended.
• Robust Networking: Zero-initialized sockaddr_in structures and centralized Winsock startup/teardown.

Version 5 - XInput Support

🎮 XInput Support

Controllers that emit signals to XInput can now be captured and broadcasted by the program.

🔌 Device Reconnection Support

The program no longer exits when the tracked DirectInput Device is disconnected; It will wait for reconnection.
This also applies to XInput and GameInput.

⚠️ BREAKING CHANGES

• Broadcast string's version section is no longer an integer
  • It is alphanumerical, beginning with version number and ending with a letter code identifying message type
    • P: Pointer/mouse/pen
    • K: Keyboard
    • D: DirectInput
    • X: XInput
    • G: GameInput
• -x flag is no longer the debug flag. Use -z instead

Version 4.1.2

⛓️‍💥 Breaking Change: New Message Format for DirectInput emitter (Protocol Version 3)

For more information, see #9
The updated Warudo translates it back to old signal values, so there shouldn't be any perceived changes.

⛓️‍💥 Breaking Change: New Flag Behaviours

• No pointer tracking is performed by default (must be explicitly specified)
  • -P flag removed
  • -p flag repurposed to enable pointer tracking
  • --target long flag renamed --pointer-target, removed -t
  • --port long flag renamed --pointer-port
• Gamepad option moved from -g to -d (for DirectInput)
  • --gamepad-* long options renamed to --directinput-*
• Debug flag moved from -d to -x
• Frequency flag default changed from 50 to 30, to better match 30 fps capture (set it to around 16 for 60 fps)

🎮 GameInput Support

GameInput support has been added. This means that Xbox Series S | X controllers are now supported.

They may be enabled with -g and customized with --gameinput-*

NOTE: GameInput had two modes: High-level controller interface and Low-level controller interface. Some controllers work better on one more than the other. For example, Xbox Series S | X only works with high level interface, while Switch Pro works better on low level interface.

👤 Interactive Mode

For discoverability and the less tech-savvy, an interactive mode is presented when executing the program without any options.
