v0.5.10

Released: 2026-04-29

Critical bugfix release. Resolves #11.

Fixed

Section titled “Fixed”
  • Discover-mode JSON output silently dropped on exit — v0.5.7 added os._exit() to bypass a libjlinkarm destructor crash, but os._exit() does not flush stdio buffers. The discover helper was successfully detecting probes via pylink, then print(json.dumps(...)) wrote the JSON into Python’s stdout buffer, then os._exit(0) terminated the process before the buffer was flushed. The JSON never reached LogScope, which interpreted “empty stdout” as “no devices found.” Symptoms: every user with v0.5.7–v0.5.9 saw “No J-Link devices found” even when a probe was attached and JLink Commander could see it. Fix: explicit sys.stdout.flush() and sys.stderr.flush() before os._exit().

This regression was platform-agnostic (Intel and Apple Silicon, macOS and Windows). It was caught when reproducing #11 locally — pylink enumerated the probe correctly when called directly, but the same call inside the helper produced no output.
