Update whenever it suits you — you can update your app and the machine you stream from one at a time, the new and old versions work together, and everything you've already paired stays paired. The new pen features simply switch on once both ends are updated. Nothing you already use changes.

## New: draw and write with a pen or stylus

You can now use a real stylus while streaming, and it behaves like a real pen on the machine you're controlling — **pressure, tilt, and the pen's side buttons all come through**, not just a plain tap. Use your **iPad's Apple Pencil** (including Pencil Pro), an **Android phone or tablet's S Pen** or other active stylus, or a pen from a Moonlight app.

It's great for drawing apps, handwriting and note-taking, signing documents, and photo editing over the stream. Windows and Linux hosts receive it as genuine pen input. If the machine you're streaming from is still on an older version, your pen keeps working as an ordinary touch.

## Fixed: your Steam Deck controller shows up as the right controller

If a Steam controller was plugged into the computer you stream from, a streamed **Steam Deck** controller could be misread by games as a **PlayStation (DualSense)** controller — so button prompts and layouts came out wrong. It now stays a Steam Deck. Punktfunk only steps in to avoid a clash when two genuinely identical controllers are present.

## Improved: a sharper, correctly-sized mouse pointer

- **Right-sized pointer on high-resolution screens.** On Linux and Mac, a pointer coming from a high-resolution host could show up about twice as big as it should. It now matches the video exactly.
- **Cleaner pointer on Windows security screens.** The mouse pointer no longer duplicates or gets stuck on Windows sign-in and User Account Control (admin permission) prompts.
- **More reliable multi-monitor streaming on Windows.** Switching between monitor layouts on the host could occasionally drop the stream — that's fixed.

## Fixed: touch input

- **Multi-touch from Moonlight apps now works on Windows hosts.** It previously registered nothing; pinch, zoom, and multi-finger gestures now come through.
- **Touch is no longer silently dropped** from some devices that report finger pressure in an unusual way.

## Fixed: Android (and Android TV)

- **Your mouse's back/forward buttons stay in the stream** instead of bouncing you out to the Android home screen — a relief on Android TV in particular.
- **The on-screen keyboard stays out of the way** when you're typing on a physical keyboard.

## Under the hood (for developers)

- The streaming protocol is unchanged, so 0.18 and 0.19 hosts and apps mix freely; the pen is negotiated and older peers simply fall back to touch.
- The embeddable core library adds one new call for sending pen input (the C ABI moves to **13**) — rebuild any embedders against 0.19. The Windows virtual-display driver is unchanged: pen goes through Windows' normal pen system, not the display driver.
- iOS builds are now attached to each release as a downloadable file (for TestFlight/archival).
