v0.9.2.1 — TGXL TUNE for firmware 4.2 hotfix

[v0.9.2.1] — 2026-04-29

TGXL direct autotune for firmware 4.2 compatibility

Hotfix release. After upgrading to SmartSDR firmware 4.2, multiple
users on both AetherSDR and SmartSDR report the TUNE button no longer
works on the 4O3A Tuner Genius XL. The radio's tgxl autotune command
path was reworked in 4.2 firmware and broke for many configurations.

This release routes the TUNE button through the TGXL's native
port-9010 channel when a direct TGXL connection is configured,
bypassing the affected firmware path. Users without a direct TGXL
connection are unaffected by this change and should still configure
direct connection in Radio Setup → Tuner to recover TUNE.

Bug Fixes

TGXL TUNE works again on firmware 4.2 (#2163)

• When a direct TGXL connection (port 9010) is configured, the TUNE
  button now sends the native autotune command directly to the TGXL
  instead of routing tgxl autotune handle=<H> through the radio's
  command channel. Falls back to the radio path when no direct
  connection is available.
• The TGXL drives radio PTT via its hardware interlock cable when it
  receives the native autotune command, so client-side keying is
  not required. Existing tuning state and SWR readout in the Tuner
  applet are unchanged.

Log redaction no longer mangles 4-component version strings

• The PII redactor's IPv4 regex matched anything that looked like
  four dot-separated 1-3-digit numbers, so the application's own
  version string 0.9.2.1 was being redacted to *.*.*. 1 in
  logs and support bundles. Negative lookbehind/lookahead now skip
  quoted ("0.9.2.1") and v-prefixed (v0.9.2.1) version forms
  while still redacting bare IPs in log output.
