release log

Version 1.6.80

Released: 05/02/2026

✨ New Features

  • Guest submission scores and Tower Defense scores are now automatically transferred to your new account and credited to the leaderboard when you sign up — no progress lost!
  • Guest XP earned during demo problem completion is now recorded and carried over when converting to a registered account.
  • New leaderboard staging system ensures guest scores are fairly integrated the moment you create an account, with deduplication to prevent score inflation.

🎮 Gameplay

  • Tower Defense success modal and Problem Workspace success modal have been updated for a smoother post-solve flow.
  • Guest signup wall now clearly surfaces the score transfer feature so you know your hard-earned progress will carry over.
  • Cluster map and cluster detail pages have received UI and data flow improvements.

📚 Learning

  • Solved problem difficulties are now matched more accurately across all identifier formats, fixing long-standing discrepancies in profile stats and solve counts.
  • Profile stats endpoint now uses robust canonical problem slug resolution so your easy/medium/hard breakdowns are always correct, regardless of how a problem was originally solved.

release log

Version 1.6.40

Released: 05/01/2026

✨ New Features

  • Added an in-app "Report Bug" button and modal on most pages so players and learners can submit feedback without leaving the site.
  • Bug reports are protected by reCAPTCHA verification and sanitized before delivery, keeping the feedback loop clean and safe.
  • Added a Support Contact panel so users always have a clear path to reach the team.
  • Introduced an SPA loading shell (spa.html) to provide faster initial page loads and smoother fallback handling on non-prerendered routes.

🛠️ Improvements

  • User-friendly toast notifications have been added across all major flows — Learning, Tower Defense V2, Problem Workspace, AI Problems, billing, profile, and auth — so failures and warnings are always explained in plain language instead of silently disappearing.
  • Login buttons (local and OAuth) now show a loading indicator while sign-in is in progress, preventing double-clicks and giving clear visual feedback.
  • Learning paths have been restructured to follow a consistent learn → tower → final format, making the progression feel more intentional and less confusing.
  • Account deletion instructions were revised for clarity and accuracy to reduce confusion during the deletion process.
  • Font loading strategy was optimized across the site for faster perceived performance on first paint.
  • Streamlined component structure across multiple pages by removing unused animations and dead code paths, reducing bundle weight.

🎮 Gameplay & Learning

  • Learning paths now serve language-specific content rather than generic fallbacks, so what you see in the problem editor actually matches the language you are practicing.
  • Tower problems now correctly localize their code display text to match the active language, preventing mismatched snippets from appearing during tower placements.
  • The Problem Workspace no longer refetches problem and score data unnecessarily when prop references change identity without the underlying values changing — sessions are now smoother and faster.
  • Learning XP handling now normalizes the modal summary more reliably, so level-up and completion modals display correctly even in edge-case session states.

🐛 Bug Fixes

  • Fixed a bug in learning problem localization where a failed code-block replacement would incorrectly substitute the entire description string instead of preserving the original match.
  • Fixed malformed NUL/control-character delimiters in the localization template by replacing them with explicit \u0000 escape sequences, preventing encoding issues across editors and CI.
  • Fixed the bug-report API path in the fetch layer so submitting a report no longer creates or persists a guest session token for already-authenticated users.
  • Java wrapper visibility timeout handling was improved to prevent stale execution states from blocking subsequent submissions.
  • CI/CD automation was hardened: release workflow now requires an explicit PR body checkbox before generating the update page entry, preventing accidental entries on routine merges.

release log

Version 1.6.00 - MAJOR UPDATE

Released: 04/26/2026

✨ Account & Progress Upgrades

  • Guest-to-account signup migration was rebuilt to carry progress forward more reliably instead of dropping important state during registration retries or duplicate requests.
  • Solved guest problems now transfer into permanent account progress more safely, including XP credit, learning-path completion, and cleaner migration bookkeeping after signup.
  • Guest cleanup and retry handling were hardened so partially migrated sessions are much less likely to leave account state inconsistent.

🧠 Execution Engine Overhaul

  • Judge0 execution handling was significantly upgraded across JavaScript, Java, C++, and Python so more problem shapes now run correctly, including linked lists, trees, graphs, design problems, and edge-case outputs.
  • Wrapper parity work fixed a large set of contract mismatches between problem metadata and actual runtime execution, reducing false negatives and broken submissions in the CODEGRIND catalog.
  • Execution plans, testcase normalization, comparator rules, and parity-validation tooling were expanded to catch production mismatches before they reach learners.
  • Judge0 warmup support was added so the platform can prewake code execution earlier and reduce cold-start friction when opening a workspace.

📚 Learning & Practice Improvements

  • Learning-path progress transfer is more dependable, especially for guests moving into registered accounts after solving onboarding and path-specific problems.
  • Practice flow reliability improved around reduced CODEGRIND problem sets, stricter execution contracts, and safer sync between problem content and runtime expectations.
  • The learning and problem workspace now benefits from better execution readiness and smoother continuity between guest usage and full account progression.

🌐 Site Discovery & SEO

  • The frontend gained a real SEO pass with prerender support for public pages, stronger metadata, expanded structured data, and a larger sitemap for better crawlability.
  • New practice-guide landing pages were added for coding interview prep, language-specific practice, gamified practice, and beginner-friendly entry points.
  • Routing and browser-only component behavior were tightened so prerendered pages, ads, storage reads, and session helpers behave more safely during static generation.

🐛 Important Fixes & Release Hardening

  • Fixed guest registration edge cases where already-migrated sessions, repeated calls, or crafted client payloads could produce inconsistent transfer behavior.
  • Resolved a broad set of wrapper bugs and testcase interpretation issues uncovered during the 1.6 production parity audit.
  • Release verification and environment guardrails were tightened so deployment checks, contract sync, and production validation are easier to trust before shipping.
