v0.2.1

When something goes wrong, sending it to me is one click, and it is always your
choice.

• If Hammerdeck quit unexpectedly, the next launch asks once whether to send a
  report. It shows what macOS recorded about the crash -- the version, the
  error, the top of the stack -- with your paths removed. Nothing leaves your
  Mac unless you press Send, and the same crash is never asked about twice.
• Report a Problem offers a GitHub issue beside email. Both start from the same
  diagnostics, which are also copied to the clipboard so nothing is lost when a
  long report has to be shortened to fit.
• Every background update check writes one line to the daily log: found, up to
  date, too new for this Mac, feed unreachable, or signature rejected. A failed
  check used to be silent.

Also: Hammerdeck installs with Homebrew
(brew install --cask kouxing2000/tap/hammerdeck). It still updates itself, so
brew upgrade leaves it alone.
