MDHero v0.2.3
What's new in v0.2.3
🎉 First external contribution
A huge thank you to @pushkarchoudhari for PR #2, the first contribution to MDHero from someone outside the maintainer team. Welcome!
Wider content area for high-DPI displays
The Content Width slider in the reader controls now reaches up to 3840px (full 4K width), up from the previous 1200px cap. Combined with the slider's smoother stepping (80px per stop), MDHero now feels right on ultrawide and 4K monitors.
- Reported by @Gh61 in #1 — thanks for the report 🙏
- Implemented by @pushkarchoudhari in #2
The default content width (720px) is unchanged. Existing readers won't see any visual difference on upgrade — only users who actively pull the slider past 1200px will notice the new range.
Carried over from v0.2.2
- Properly sealed macOS code signature (friendlier Gatekeeper dialog on first launch — see v0.2.2 release notes for the install workaround)
