v0.9.5.1 — Stability & polish hotfix sweep

on GitHub

Stability & polish hotfix sweep

A focused follow-up release that lands the TCI TX policy hotfix plus six
post-v0.9.5 fixes already in main: SmartLink WAN reconnect after radio
drops, sequenced WAN disconnect teardown, RX slice-tab reset between
radios with different slice counts, macOS panadapter pop-out live
updates and dock-splitter layout, NR2 wisdom-generation safety on the
audio thread, and a Qt log-handler serialization fix that resolves a
macOS tune-time crash.

Big thanks to @rfoust (four SmartLink / disconnect / macOS polish
fixes) and @jensenpat (NR2 audio-thread safety + Qt log
serialization) for landing the bulk of this release.

Bug fixes

TCI TX silent on Windows / Linux non-PipeWire (#2276)

• evaluateDaxTxPolicy() now always allows DaxTxRequestReason::TciTxAudio
  regardless of platform / hosted-DAX availability. TCI receives audio
  over WebSocket and feeds it into a dedicated dax_tx stream that's
  independent of SmartSDR DAX2 (which owns the Windows DAX audio
  devices, not the radio's dax_tx stream slot — multiple GUI clients
  can each register their own).
• Test assertions in tests/radio_status_ownership_test.cpp flipped to
  match the corrected policy and a new Linux-non-PipeWire test case
  added.

SmartLink reconnect after WAN drop (#2282, rfoust)

• MainWindow now owns a WAN reconnect timer that re-requests a
  SmartLink radio connection using the last selected WAN radio when
  RadioModel reports an unexpected WAN disconnect, instead of
  leaving the app stuck on the "Radio disconnected — waiting for
  reconnect" popup.
• SmartLinkClient::reconnect() refreshes Auth0 credentials via the
  saved refresh token before reconnecting, avoiding reuse of an
  expired id_token. Auth-refresh failure stops the retry loop and
  shows a sign-in-required status instead of retrying forever.
• RadioModel::forceDisconnect() now handles WAN connections so
  missed pings transition the app to disconnected/reconnecting
  promptly. Ping watchdog logs and forces disconnect once per outage
  rather than every second.
• PanadapterStack::prepareShutdown() releases QRhi GPU resources
  before main-window teardown to avoid the macOS Metal teardown crash
  that could fire after a stale-state Disconnect.

SmartLink disconnect teardown (#2278, rfoust)

• WAN disconnect previously closed the WAN socket after disconnecting
  RadioModel's signals and nulled m_wanConn directly, skipping
  RadioModel::onDisconnected() cleanup entirely. Panadapters,
  slices, meters, and streams stayed alive in the model after the user
  clicked Disconnect.
• Now runs the normal model teardown path on intentional WAN
  disconnect, so WAN sessions emit connectionStateChanged(false) and
  clear model state the same way LAN disconnects do.

Reset RX slice tabs on disconnect between radios with different slice counts (#2254, rfoust)

• RxApplet::clearSliceButtons() tears down generated slice tab buttons
  and restores the static slice badge on disconnect. Stale A–H buttons
  no longer linger after switching from a high-slice radio to a
  smaller one.
• MainWindow's infoChanged initializer is now per-connection rather
  than one-shot, so each radio rebuilds its slice row from its own
  maxSlices. Slice button click connections are guarded against
  duplicate signal handlers across reconnects.

Qt log handler serialization fixes macOS tune-time crash (#2284, jensenpat)

• The global qInstallMessageHandler callback wrote through a single
  QFile* without synchronization, and concurrent qCInfo/qDebug
  output from main + worker threads corrupted Qt's internal file
  write-buffer state. The tune-policy diagnostic line happened to be
  the log call that exposed the corruption — the failing object was
  the logging sink, not the Flex tune command path.
• Now serializes the handler with an intentionally leaked mutex
  (mirroring the existing shutdown-safe treatment of the redaction
  regexes) and replaces per-message QTextStream wrapping with a
  direct UTF-8 QFile::write()/flush() path. No change to radio
  command ordering or panadapter policy.

macOS panadapter pop-out refresh + multi-pan dock layout (#2280, rfoust)

• Detached panadapter windows on macOS no longer show a static/stale
  spectrum image. Cross-window reparenting now resets the native
  QRhi/Metal surface and re-requests pan dimensions from the radio
  after every float/dock cycle.
• Saved floating-window state is no longer restored after later
  user-added pans, so adding a second panadapter does not spawn an
  unwanted blank floating window.
• rebuildDockedSplitter() keeps the main-window splitter compact
  when multiple pans float/dock — no more empty placeholder slots.

NR2 wisdom generation no longer freezes the audio thread (#2275, jensenpat)

• AudioEngine::needsWisdomGeneration() previously only checked
  whether aethersdr_fftw_wisdom existed. If the file was stale or
  incompatible (e.g. fftw-3.3.10 header on a build that uses FFTW
  3.3.11), setNr2Enabled() ran full FFTW wisdom generation on the
  audio worker thread, blocking RX audio and the WAVE scope for
  several minutes.
• Adds SpectralNR::loadWisdom() for import-only validation, makes
  needsWisdomGeneration() return true when the file exists but
  cannot be imported, and routes generation through the existing
  background progress dialog instead of the audio thread. If wisdom
  import fails at enable time, NR2 falls back to runtime
  FFTW_MEASURE plans rather than hanging audio.
