## Version history (last 5 releases)

### 2.4.1 — 2026-08-01

Fixes a first-launch problem where no system was active and the appearance setting did not apply until you restarted the app.

Times now follow your device's 12/24-hour format again, and the comparison view no longer shows a percentage for today while the day is still running. Monthly and year-to-date figures keep theirs, marked "so far".

### 2.4 — 2026-08-01

New: HelioPeak widgets for your Lock Screen, in round and rectangular shapes.

Also: the yearly chart now shows both production and consumption when you tap a bar, the iPad weather display recovers on its own after a network problem, and the "PVOutput is temporarily unavailable" message no longer appears when it shouldn't.

Privacy: crash reports no longer contain any system identifier, and eleven unused measurements have been removed from the app.

Plus translation fixes and improvements to stability and speed.

### 2.3.2 — 2026-05-25

HelioPeak 2.3.2 — Send your solar data to an AI assistant

NEW: Export for AI Analysis
Generate a self-contained file with your full production, consumption, and grid data, plus a structured prompt designed for AI assistants. Paste it into Claude, ChatGPT, Gemini, or any other AI of your choice and get a detailed 14-section analysis. No subscription, no server in the loop, your data stays with you.

- Choose between Large (24 months of data) or Small (3 months) depending on which AI you'll use
- Pick the response language: English, Dutch, French, German, Italian, or Spanish
- Multi-system export — select which systems to include
- One-tap share to Mail or Messages bundles the prompt and the file together, ready to forward to your AI assistant
- Available free for all users from Settings → Export & Reports

NEW: Grid cards on every tab
Grid Import and Grid Export cards now appear on all three Dashboard tabs (Production, Consumption, Combined) and on the matching Day charts. Cards automatically hide for systems without grid data.

Reliability
- Fixed a freeze that could briefly affect cold launches on older devices with multi-year histories
- Resolved an edge case in the cached data export where a small amount of legacy data could cause a partial export
- Help & FAQ deep-links from Settings now navigate correctly on the first tap

Privacy & Security
- API key entry now uses a masked field with a reveal toggle, matching iOS best practices for credentials
- Tightened error handling to ensure no PVOutput response details ever appear in user-visible error messages

Thank you for using HelioPeak. As always, feedback is welcome at info@heliopeak.app.

### 2.3.1 — 2026-05-19

In this version (v2.3.1), we focus on reliability & performance improvements:
- Faster cold launch: the Solar Moments engine no longer slows down the Dashboard on app open, especially for users with long PVOutput histories
- Snappier chart cursor and Y-axis rendering
- Health indicators now stay accurate when you don't open the app every day
- Pull-to-refresh on Charts now waits for data to actually load
- PDF export no longer freezes the app
- Widget timestamp ("Updated HH:MM") now follows your in-app language instead of falling back to English
- Stronger privacy in error logs

### 2.3 — 2026-05-17

Solar Moments, a new way to stay connected with your panels.

HelioPeak now automatically detects noteworthy events in your production: new records, milestones, anniversaries, perfectly symmetric sunny days. 16 detectors run directly on your device, private, fast, no server.

New in this version:
- Shareable moment cards in 4 styles and 3 formats (Instagram feed, Stories, LinkedIn)
- Smart notifications with strict limits (max 1 per day, quiet hours 22:00-08:00)
- 6 categories you can toggle independently
- Pause 1, 7, or 30 days
- Archive of your last 100 moments

Plus faster Dashboard loading on long production histories and smaller refinements throughout the app.
Bug fixes and performance improvements.

Solar Moments is free for everyone. Detection happens 100% locally, your data never leaves your device.
