Original release notes

What's New in This Update

Smarter, faster AI
• Upgraded to GPT-5 (and GPT-5 mini on the free tier) for sharper answers and fewer formatting glitches.
• Responses now stream in chunk-by-chunk and type out smoothly on screen.
• A new pulsing indicator shows when the AI is thinking.

Cleaner responses
• Reworked how answers are generated and rendered: code stays in code blocks, prose stays as prose.
• Redesigned Code Explanation page with a syntax-highlighted code preview and a clean markdown body for the explanation.

Better Code Editor
• Simulated languages (everything outside JavaScript, TypeScript, and Python) now produce noticeably more accurate, consistent results.
• Output and errors are shown in separate, clearly-labeled panes.

Challenges, refreshed
• New card design with color-coded difficulty pills (Easy, Medium, Hard, Advanced), a "Completed" badge for finished challenges, and a clearer locked state.
• The whole card is now tappable with a proper ripple effect.

Plus security hardening and a bunch of smaller fixes.
