MDHero v0.2.4
What's new in v0.2.4
🍎 Notarized macOS builds — no more Gatekeeper friction
MDHero is now signed with an Apple Developer ID and notarized by Apple. On first launch, macOS shows only the standard "This app was downloaded from the Internet" prompt — no more "cannot be verified" warning, no more xattr -cr workaround, no trip through System Settings → Privacy & Security.
If you've been running an older version, the upgrade just works — drag the new app to Applications and double-click.

A big thank you to @vpndev18 for their first contribution to MDHero — the cleaner inline code rendering below (#9). Welcome!
Press ESC to close — like every other reader
A new Close on Escape setting (on by default) closes the current tab when you press ESC. If it was the last tab, the app fully quits — so MDHero is now usable as the default .md viewer in file managers: right-click → Open With → MDHero → read → ESC.
The toggle lives in a new Settings dialog (gear icon in the toolbar, or Cmd+,). If you'd rather have your old ESC behavior back, flip it off there.
Cleaner inline code rendering
Inline code spans like Cmd+O or pnpm install no longer render with literal backtick characters around them. This brings MDHero in line with GitHub, GitLab, Bitbucket, and every other Markdown viewer.
