Build the Windows client against the MSVC ABI while retaining clang
language support. Use vcpkg for ANGLE and libsamplerate, and build
MsQuic with its bundled static OpenSSL.
Report the exact MsQuic status and initialization stage when network
transport construction or connection fails.
Diagnose certificate, stream, protocol, and peer shutdown failures
instead of returning only the generic transport error.
Decode each subblock from its proper bitplane offset.
Keep reconstructed wavelet levels in separate textures.
This lets inverse transforms safely write the next level.
Replace the single-owner PCM queues with one shared LGMP SPMC stream.
Give each admitted client reliable state and an independent playback
cursor, while clients without clock authority resample locally.
Extend the audio protocol with per-client epochs and barriers.
Keep capture exclusive and bound authority backpressure so slow
secondary readers cannot affect the disciplined low-latency path.
Give microphone data priority over replaceable clock feedback and
reduce feedback traffic on the shared client-to-host FIFO.
Retry short FIFO stalls outside the realtime thread and coalesce
consecutive packets in the existing fixed Windows buffers.
Avoid one broker write per tiny PipeWire quantum without adding
allocations or intentional capture latency.
Advertise signed and floating-point 32-bit formats across mono,
stereo, quad, surround, 5.1, and 7.1 at every supported rate.
Carry sample encoding through the broker and LGMP protocol so integer
and floating-point streams remain distinct.
Expand packet, shared-memory, and ring capacity for eight-channel
32-bit audio.
Treat the binding phase as the authoritative shutdown state after
graceful stream release.
Cover disconnect while the host drains and unbinds both streams.
Scope the legacy latency offset to classic SPICE and use the LGMP
poll bound as its fixed arrival reserve. Keep learned jitter additive.
Select provider clock feedback only when the current remote endpoint
advertises it, avoiding a failed startup attempt on broker v1.
Release LGMP stream slots before dispatching clipboard data so an X11
INCR consumer cannot prevent control queue acknowledgements.
Retain one bounded record in client memory while the sink is blocked.
Cancel abandoned X11 transfers after requestor destruction or a finite
progress timeout.
Add LGProtocol as a pinned submodule and consume its KVMFR protocol
definitions throughout the client, host, IDD, OBS, and profiler.
Keep Looking Glass framebuffer helpers local while removing duplicated
protocol headers and migrating users to KVMFR-scoped types.
Cache native keyboard lock state across input-provider transitions and
reconcile it with HID LED feedback over LGMP.
Project raw and corrective lock-key transitions through the reliable
input FIFO, defer correction until outstanding transitions settle, and
recover from delayed or missing feedback without double toggling.
Report guest HID keyboard LED state from LGInput to LGIdd and
publish it with the LGMP input endpoint status.
Forward SPICE modifier updates through the same provider state so evdev
can synchronize physical keyboard LEDs across transport changes and
reconnects.
Bump the versioned pipe and KVMFR input status contracts for the new
feedback state.
Accept earlier LGMP input status versions without LED feedback so the
client retains input while the guest driver is being upgraded.
Add a configured escape key plus Shift+R command that requests display
recovery from the LGMP transport and switches video to SPICE.
Track the request on the main thread, report its asynchronous result,
and return its producer instance with the request serial for exact
correlation.
Preserve normal escape+R rotation behavior, including custom Shift
escape keys.
Heartbeat expiry does not change the LGMP session ID. Queue operations
can therefore accept ownership releases into stale shared memory after
a guest reboot, where no host remains to advance the acknowledgement
serial.
Skip graceful clipboard and input ownership release when the session is
already invalid. Keep the existing timeout and warning for a live host
that fails to process the release.
