Changelog

What's shipped on Fun UI Playground, newest first — new challenges and site features.

A hand-curated, user-facing history of what shipped, newest first.

2026-07-27

Fixed the configured mobile header so the optional account button, brand, theme toggle and menu never overlap from 320–390px.
Made search compose with active filters, added guided learning paths, clearer completion guidance and actionable live-backend setup help.
Added a privacy and data-use page, clarified optional analytics/account wording, expanded the blog to five practical articles and strengthened full account/mobile regression coverage.

Fixed a sync bug that could lose progress: signing in now refreshes the page you are already looking at instead of leaving stale numbers on screen until a reload — and an open challenge page can no longer write its pre-sync copy back over what your account just restored.
Fixed the live backend's rate limiter counting every visitor as one client in production, so /api/limited's budget is now genuinely per-client — and Digest Auth no longer re-prompts for the password at random mid-exchange.
"Reset local data" now signs you out of your account on this device too, instead of leaving a signed-in session behind that quietly restored everything you had just cleared.

Added email/password sign-in alongside Google, a password-reset flow at /reset-password, and an account page at /profile with your stats, provider, sign-out and account deletion.

Added optional cloud progress sync — sign in to carry your completed challenges, bug-hunt findings and badges across devices. Everything still works without an account.
Added a badge/achievement system with unlock toasts and a full catalog at /badges, plus an exam context bar that keeps a run visible while you work through it.
Added a per-category progress dashboard on the home page, a "continue where you left off" link, and shareable progress / exam-result cards you can download as an image.
Added "Completed" / "Not completed" and "Live backend only" filters alongside the existing category and difficulty chips.
Added a hint (collapsed by default) to each of the six hardest challenges: Drag and Drop, Obscured Elements, Nested Frames, Shadow DOM, Challenging DOM and Digest Auth.
Added this changelog.

Added Random challenge, Exam mode (timed self-graded runs), the command palette (Ctrl/Cmd+K), per-framework starter-kit downloads, an RSS feed for the blog, and an opt-in Flaky mode for practicing wait strategies.
Unified the mobile header/menu across every page and gated analytics behind visitor consent.

Added the Digest Auth, Dynamic Content and Challenging DOM challenges.
Added five more challenges, CI speed knobs (?delay=…) and a real rate-limited API endpoint.
