-## EternalMonitor unreleased
+## EternalMonitor v0.3.1
 
-- Windows and iPad can share diagnostics automatically with support, queue events while offline and retry after reconnecting. Automatic sharing can be disabled in Settings.
+Install the Windows and iPad 0.3.1 updates together. This release includes Intel
+hardware-encoding fixes and automatic support diagnostics. The affected Windows
+10 / Intel Iris Xe device and physical iPad Pro M5 still need customer testing.
 
-- Windows and iPad now retain bounded support logs across launches, including device/build details, encoder/decoder errors and stream summaries. Export iPad reports from Settings → Diagnostics. Windows Copy logs includes native FFmpeg driver errors and removes pairing credentials.
+### What changed
 
-- Fix Intel Quick Sync startup by converting capture frames to its supported
-  NV12 input format for H.264 and HEVC.
-- Try the other Windows hardware encoders when the preferred encoder cannot
-  open, before falling back to CPU encoding. Record each failure in the host log.
+- Intel Quick Sync uses its supported NV12 input format for H.264 and HEVC.
+  Windows tries the remaining hardware encoders before falling back to CPU
+  encoding and records each startup failure.
+- AMD keyframe requests survive delayed encoder output, improving recovery when
+  the iPad requests a fresh frame.
+- The Windows host sends queued audio between video packets, reducing audio
+  loss during large video bursts.
+- Windows and iPad retain bounded logs across launches, including device and
+  build details, encoder or decoder errors, connection history and stream
+  statistics. Windows Copy logs includes native FFmpeg errors. On iPad, open
+  Settings > Support > Diagnostics to copy or export a report.
+- Both apps automatically send support diagnostics while running and retry
+  queued events after reconnecting. Reports include device details, PC names
+  and network addresses. Screen content, audio and pairing credentials are
+  excluded. Automatic sharing can be disabled in Settings.
+
+### What to test
+
+Update both apps, keep the PC and iPad online, then connect over USB with Apple
+Devices open on Windows. Stream for two minutes and check whether the hardware
+encoder warning returns. Test H.264 first, then HEVC if you use it. If a problem
+continues, send the time and time zone, a screenshot of the warning and the
+Diagnostics upload status so support can find the reports.

-# EternalMonitor 0.3.0: What to Test
+# EternalMonitor 0.3.1: What to Test
 
-v0.3.0 is the current stable release. Install the Windows app with iPad
-v0.3.0, TestFlight build 143. The Windows installer is unchanged from
-v0.3.0-rc.1. It passed the automated tests on the reference PC and a physical
-iPad; the hands-on checks below remain. New users can follow SETUP.md.
+Install the Windows and iPad 0.3.1 updates together. This release includes Intel
+hardware-encoding fixes and automatic support diagnostics. The affected Windows
+10 / Intel Iris Xe device and physical iPad Pro M5 still need customer testing.
 
 ### What changed
 
-- Lost video fragments can be requested again within a bounded repair window.
-  The window follows real WiFi timing: it waits for late and reordered packets
-  instead of discarding their frames. The quality popover reports repaired
-  fragments, dropped frames and jitter.
-- A USB connection uses Apple's device service on Windows and the same negotiated
-  session as WiFi. The app can take over when a cable connects and reconnect to
-  WiFi when it disconnects. USB needs Apple's Apple Devices app from the
-  Microsoft Store, open while you stream. When an iPad is plugged in and Apple
-  Devices is closed or missing, the host says so and offers to open it or links
-  to the Store. Accept Trust This Computer on the iPad.
-- PC audio uses 48 kHz stereo Opus. The iPad's audio setting mutes playback without
-  disconnecting video. Quiet packets are compact; Opus packet-loss concealment
-  covers missing audio. This version does not provide Opus in-band FEC.
-- Pair with the six-digit host code or its QR code. Remembered hosts use a token
-  stored in the iPad Keychain. Regenerating the host token requires pairing again.
-- Hardware and on-screen keyboards, sticky modifiers, indirect pointer buttons
-  and hover extend the existing touch and Pencil controls.
-- Apple Pencil draws as a Windows Ink pen with pressure and tilt. Drawing mode
-  ignores fingers on the canvas, mutes PC audio and asks for the highest USB
-  frame rate. In Clip Studio Paint, choose the Tablet PC setting.
-- The host offers 30/60/90/120 fps; the iPad requests 30/60/120 fps. The lower limit
-  wins. HEVC remains optional. YUV420 remains the default encoder input because
-  the AMD encoder does not accept BGRA; BGRA input is opt-in.
-- The host shows client, USB and audio status, rotates its session log, and can
-  check for updates. The Windows installer configures its firewall rules and VDD
-  task permissions. Continue checking these Windows behaviors on your hardware.

+  Windows tries the remaining hardware encoders before falling back to CPU
+  encoding and records each startup failure.
+- AMD keyframe requests survive delayed encoder output, improving recovery when

-### Please exercise on a physical iPad
+### What to test
 
-Pair on the local network, test H.264 and HEVC, then type and scroll through the
-keyboard and trackpad. Connect, unplug and reconnect USB. Play audio and check
-sync, mute and a Windows output-device change. Walk toward the WiFi edge and
-watch repairs rise without long freezes. On a ProMotion iPad, try 120 fps with
-the virtual display at 120 Hz. Draw in Clip Studio Paint with Drawing mode over
-USB, including pressure, tilt and a resting palm. Report the GPU, codec, host
-log and visible error.
-
-On the reference PC a physical iPad streamed the 2732×2048 extended desktop over
-USB-C for 30 minutes at 58 FPS with no dropped frames, and 3440×1440 over WiFi
-for 30 minutes with 19 of 105,600 frames dropped. First-install trust, timed
-takeover and WiFi fallback still need the hands-on pass. Pairing controls access but does
-not encrypt video, audio or input, so use a trusted local network.
-
-Known issue: on the reference PC (NVIDIA driver 591.86), Windows once stopped
-with an NVIDIA kernel error about two seconds after a USB connection switched a
-running mirror session to the extended display. A bounded retest of the same
-build and driver repeated that switch five times, and later runs repeated it
-again, without a crash. The driver fault is not understood. If it happens,
-report the GPU driver version and the time.
+Update both apps, keep the PC and iPad online, then connect over USB with Apple
+Devices open on Windows. Stream for two minutes and check whether the hardware
+encoder warning returns. Test H.264 first, then HEVC if you use it. If a problem
+continues, send the time and time zone, a screenshot of the warning and the
+Diagnostics upload status so support can find the reports.
