Ships the dialog reorganisation and mnemonic adjustments from
commit 45b709d. No wire-format or audio-pipeline changes — v1.3 and
v1.4 peers interoperate.
About dialog gets a v1.4 release-notes block; csproj Version
property bumped 1.3.0 → 1.4.0; RELEASE_NOTES.md rewritten with the
v1.4 highlights and a one-paragraph upgrading-from-v1.3 note (clean
auto-update via Help → Check for updates is now expected to work on
Dropbox-installed copies since v1.3's helper hardening took effect).

Recording settings dialog
=========================
Promote what were row attributes inside the format-attributes table
into their own dedicated listboxes. Pre-rework each format's
attribute list contained a row per (quality knob × channel mode)
combination — doubling the row count for no real benefit. WAV had
6 rows, MP3 / OGG-Opus had 8, FLAC had 4. Channel mode is now its
own listbox; per-format attribute lists shrink to 3 (WAV), 4
(MP3 / OGG-Opus), 2 (FLAC).
FLAC compression level was previously a hidden RecordingSettings
field locked at the libFLAC default of 5. Now exposed as its own
conditional listbox with all 9 levels (0..8). Visible only when the
selected file format is FLAC; the column collapses to 0% width
otherwise so the dialog reads cleanly as 4 columns for non-FLAC
formats and 5 for FLAC.
Mnemonics:
* Source Alt+S (unchanged)
* File format Alt+F (unchanged)
* Attributes Alt+A (unchanged)
* Compression Alt+L (new, FLAC-only visible)
* Channels Alt+C (new)
* OK Alt+O (unchanged)
* Cancel Alt+N (was Alt+C — moved to free C for Channels)
Record menu mnemonics
=====================
Item mnemonics inside the Record menu reorganised so the keystroke
inside the menu matches the same letter used for Ctrl+R outside it,
and Settings reads naturally:
* Start recording / Stop recording Alt+R (was Alt+S)
* Recording settings Alt+S (was Alt+T)
* Open recordings folder Alt+O (unchanged)
* Change recordings folder Alt+C (unchanged)
UpdateStartStopRecordingMenuLabel keeps the underline on a literal
R in both states ("Sta&rt recording" → "Stop &recording") so the
keystroke does the same job regardless of which label is active.
No version bump — the running version stays at 1.3.0. These changes
will be bundled with the next public release alongside whatever else
is in flight.

Anyone on v1.0 / v1.1 / v1.2 in a Dropbox-synced folder will hit the
auto-updater bug v1.3 fixes — but the fix lives in the running
version's helper, so their installed binary can't use it. Adds a
prominent "Already on an older version and inside a Dropbox folder?
Read this first" section at the top of the release notes with the
manual-install steps, and renames the existing install steps to
"Install (clean machine)" for clarity.

v1.2's self-updater silently failed when the install folder lived
inside a Dropbox sync path. Dropbox held write locks on the existing
RemSound.exe / DLLs during the brief window between the parent exiting
and the helper script copying the new files in. The helper's robocopy
(/R:5 /W:1) gave up after 5 seconds, and the helper then
unconditionally relaunched the OLD binary — so the user saw the same
version they started with after pressing "Yes" on the install prompt,
with no visible error.
Helper script (BuildInstallScript) changes:
* Robocopy retries bumped to /R:60 /W:1 — up to 60 seconds per file.
Dropbox lock release happens reliably within that window in
practice.
* Robocopy exit code is captured and checked. Codes >= 8 are real
failures. On a failure the helper writes update-failed.txt to the
install folder with the cause + recovery steps, leaves the staging
folder intact, and does NOT relaunch the old binary. Earlier
versions silently relaunched the unmodified old binary, hiding the
failure.
* Helper appends a step-by-step trace to _update-helper.log (in the
install folder), with robocopy's own output included via /LOG+:.
* update-failed.txt, _update-helper.log, and _apply-update.cmd are
added to the /XF exclusion list so the helper's own state files
don't get copied to themselves on a repeat update run.
DownloadAndStageInstallAsync also clears any stale update-failed.txt
at the start of every new attempt, so a successful run leaves the
install folder clean.
readme.html "If install fails" section expanded with the new
update-failed.txt marker file behaviour and the _update-helper.log
location.
Wire format, audio pipeline, and recording feature unchanged from
v1.2 — this is updater-machinery-only.

New user-facing features:
* Recording. Dedicated Record menu (Alt+O — moved from Alt+R to
avoid clashing with the Receive audio checkbox), Start/Stop on
Ctrl+R, settings dialog, per-profile source / format / bit-depth /
channel-mode / folder. Three source modes (received only, sent
only, both). Files are crash-resilient — a process crash
mid-recording leaves a playable file containing everything up to
the last header refresh (~5 seconds).
* Four output formats, all functional:
- WAV: 16/24-bit PCM or 32-bit float, custom writer with
periodic RIFF re-patching.
- MP3: LAME 128–320 kbps CBR (via NAudio.Lame).
- OGG-Opus: 96–256 kbps VBR (via Concentus.Oggfile, reusing the
Concentus encoder from the wire path).
- FLAC: 16/24-bit lossless (via CUETools.Codecs.FLAKE — pure
managed, no native DLL).
* Recording start/stop sound cues. record start.wav and
record stop.wav play around the recording transition. Played via
System.Media.SoundPlayer to the default Windows output, separate
from the recording pipeline so a normal recording does not contain
the cue.
* Per-cue Preferences. The old single "Mute connect/disconnect
sounds" checkbox is replaced by a CheckedListBox: Connect /
Disconnect / Recording start / Recording stop. Old profiles with
the legacy MuteConnectionCues=true are honoured on first load via
a migration path in the new Load* helpers.
* Receiver-side drift compensation switched from discrete
single-frame splices to a continuous WdlResampler at a smoothed
rate ratio. SessionPlayout.cs rewrite.
Diagnostics (only active with Enable logs ticked):
* Per-stage discontinuity probes — sender raw capture (per backend,
PushModeWasapi + Asio both wired), sender pre-encode (now per
lane in BothIndependent, fixing a cross-stream artefact), receiver
post-decode, post-ring, post-resampler.
* Wire-level packet sequence tracking on each PCM stream — in-order
/ missed / reordered / duplicated counts in the diag log.
* Clipped-sample delta in the diag log.
* New AudioStepProbe in RemSound.Core with per-channel scan helper.
UI changes:
* Record menu uses Alt+O (Rec&ord). Inside the menu, item mnemonics
unchanged (S / T / O / C).
* Auto-tune interval combo label is mode-aware: "Auto-tune latency
interval" in classic modes, "Auto-tune interval — WASAPI and ASIO"
in BothIndependent. The combo's Enabled state now follows EITHER
lane's auto-tune checkbox (was only the WASAPI one — bug).
Wire format and audio pipeline unchanged from v1.1 — v1.1 and v1.2
peers interoperate.

Adds a v1.1 block above the existing v1.0 block in the About dialog,
covering the priority-mode feature, always-on network packet priority,
larger UDP kernel buffers, MMCSS Critical bump, and the logging-toggle
bug fix. Version property in the .csproj bumped from 1.0.0 to 1.1.0 so
the About dialog heading and the self-updater's CurrentVersion both
report 1.1.

Priority mode (per-profile toggle, Audio profile tab, Alt+U):
- Bundled PROCESS_POWER_THROTTLING_STATE with EXECUTION_SPEED and
IGNORE_TIMER_RESOLUTION flags (keeps CPU at full clock + 1 ms quantum
pinned regardless of OS idle decisions)
- PowerSetRequest(EXECUTION_REQUIRED) + SetThreadExecutionState so the
system can't decide we're idle and downclock
- timeBeginPeriod(1) for 1 ms scheduler quantum
- ProcessPriorityClass.High, ProcessMemoryPriority normal, working-set
minimum locked via SetProcessWorkingSetSizeEx(HARDWS_MIN_ENABLE)
- Fully reversed on toggle-off and on form close
- Off by default (battery cost on laptops); explicit opt-in per profile
MMCSS thread priority on hot threads bumped from High to Critical
(network listener, mix loop, render thread) — always on.
Network packet priority (always on, no toggle):
- qWAVE flow on the outbound UDP socket at QOS_TRAFFIC_TYPE_VOICE with
QOS_NON_ADAPTIVE_FLOW (Voice priority, DSCP 46/EF, WMM Voice on Wi-Fi)
- Silent fallback if qwave.dll missing or QoS service disabled
- Sender + receiver kernel UDP buffers bumped to 1 MB each (was
256 KB send / 512 KB receive) for resilience against ~30 ms stalls
Bug fix: PreferencesDialog logging toggle no longer flags the profile
as dirty. Logging is a machine-local AppConfig setting; the spurious
ChangedAnyProfileSetting flag was triggering the unsaved-changes prompt
on exit after toggling logs alone.
Manual updated: new "Use CPU and Windows performance settings in high
priority mode (Alt+U)" subsection on the Audio profile tab, new
"Network packet priority (qWAVE / Voice / WMM)" subsection in the
network chapter, Alt+U row added to keyboard-shortcuts table.
