CW Notebook 1.0.49 - digital modes and callsign flags

CW Notebook 1.0.49 brings BPSK31/63, JS8 and Olivia reception to the public release, alongside CW and parallel RTTY.

• Monitor the full captured spectrum with shared analysis and bounded decoder slots. Radio's tuned passband and pinned signals receive priority; frequency tabs keep received streams separate.
• Receive BPSK31/63, all five JS8 speeds and seven common Olivia formats. JS8 header callsigns, grids and remote reports appear when transmitted.
• Read signal-qualified local RX SNR for every mode. Keep the last signal reading through noise-only gaps, with reception age/time and mode-colored tabs.
• Use paged Settings, optional offline callsign flags, clickable QRZ tags and HAM QSO highlighting. Annotations leave received text and CW logs intact.
• Avoid misleading RTTY country annotations when a one-off token adds a leading letter to an otherwise repeated, recognized call. Received letters are never removed or corrected.
• Close CW with its tab X to stop its private receiver and learning; enable CW to reopen it while retaining confirmed text and logs.
• Copy reception metadata or use Explain with AI from digital tabs, matching CW's browser/clipboard workflow.

Includes the development work from 1.0.43 through 1.0.48. Digital text remains memory-only: copy wanted reports before closing tabs or quitting. Weak, overlapping or unsupported signals may be missed. Callsign country is an offline prefix estimate, not verified identity or location.

Packages: Apple Silicon, macOS 15 or newer. Use brown only with SDR++Brown 1.2.1 (August 4, 2026 build), or sdrpp with SDR++ 1.2.0 (May 28, 2024 build). Host plugin ABIs differ; do not interchange binaries. Binaries are community builds, not Developer ID signed or notarized.

Quit the selected host before installing. Verify the ZIP against SHA256SUMS.txt, then run the included installer with the matching host option. The installer backs up configuration and the previous plugin outside the host app bundle. See the packaged README for commands and rollback instructions.

Validation: fifteen core targets, five installer checks, full ASan/UBSan checks, both matching host builds and both native-ImGui suites. Brown 1.0.49 was installed and observed receiving live RF, with all 34 saved CW log prefixes preserved. Six-mode native replay was tested during this development cycle. These checks do not establish universal RF sensitivity or long-soak stability.
