Changelog

[1.3.0]

2026-04-25

New Features

Design system v2

• Refreshed visual language across the app: new typography scale, colour tokens, header, and homepage layout.
• Draft session now uses a 3-column collapsible panel layout — pool, pack, and AI coaching panel are all visible simultaneously.
• Commander discover page redesigned with a sidebar navigation and card list view.
• Right sidebar accordion replaces the original onboarding tour — cleaner first-run experience without hand-holding.
• Metagame archetype cards are now clickable through to full deck detail views.

Infrastructure

• Turso/SQLite runtime removed — the app now runs exclusively on PostgreSQL for better reliability and scaling.
• MagicCon scaling hardening: health endpoint, kill switches, and signup rate limits added to handle traffic spikes.

Fixes & Improvements

• Commander anonymous flows, empty states, and error affordances overhauled.
• Rogue article generation: real deck validation, colour-identity warnings, fixed section-case crash, correct land-count scoring for aggressive builds.
• Standard brew page unblocked when metagame snapshot is partial.
• Coaching: win-turn estimates updated; banned Mana Crypt replaced in bracket calibration examples.
• Commander: minimum card count enforced on save; “Choose a Background” keyword recognised for background pairings.
• Draft: set readiness surfaced in UI; pack-size default corrected from 14 to 15 cards.
• Accessibility: loading spinners use role="status"; filter chips have visible focus rings; rogue article headers are keyboard-navigable.

[1.2.x]

2026-04-20 – 2026-04-22

New Features

Arena & MTGO deck export

• Commander and Standard decks can now be exported in Arena-format text for easy import into your client of choice.

Partner commander support

• “Partner with X” commanders are now correctly recognised in the Commander builder UI.
• A partner selector has been added to the AI Brew page so you can pair compatible partners before generating.

Footer version display

• The footer now shows the checked-in release version from the git tag, so you always know exactly which build you're on.

Security Hardening

• CSRF tokens added to logout and billing checkout routes.
• Session ownership checks centralised — eliminates an IDOR risk where users could act on other users' sessions.
• Rate limiter moved to a database-backed implementation so it persists correctly across Vercel serverless instances.
• Encryption key versioning added to support safe key rotation without invalidating existing sessions.
• Zod schema validation added to all JSON.parse call sites.

Fixes & Improvements

• Default LLM updated to Gemini 2.5 Flash for rogue and metagame RAG queries.
• Rogue viability scores are now computed from actual deck data instead of hardcoded values.
• Standard brew and rogue navigation differentiated — separate entry points, clearer purpose for each tool.
• Standard brew page gated on snapshot availability to prevent empty or misleading output.
• Coaching: 2-card packs now routed to the LLM instead of the template-response path.
• Coaching: creature-count warning threshold corrected from <12 to <14.
• Coaching: bomb-rating examples updated to accurate 5.0 references (Serra Angel replaced).
• www.adria-mtg.com now redirects to adria-mtg.com.
• Audit log writes awaited to prevent data loss on serverless teardown.

[1.2.0]

2026-04-19

Stability & Reliability

Critical stability fixes

• Environment variable validation tightened — misconfigured deployments now fail loudly at startup instead of silently mid-request.
• Rate limiter now fails closed (denies requests) when the backing store is unavailable, preventing abuse during outages.
• Draft pick writes wrapped in a database transaction with automatic rollback on timeout.
• JSON.parse call sites guarded against malformed LLM responses.

Error monitoring and observability

• Sentry error reporting wired up for both client and server paths.
• DB timeout tightened to 27 seconds; Scryfall requests now use abort signals to prevent zombie fetches.
• Errors previously swallowed in silent catch blocks are now logged.

UX improvements

• Auth expiry handling improved — expired sessions surface a clear re-login prompt instead of a generic error.
• Pick resync UX added — if a pick goes out of sync, the UI recovers gracefully with a visible retry state.
• Session state warnings shown when the draft session is in a degraded or partial state.
• DB health probe added to the retry backoff path — prevents retrying when the database is provably down.

[1.1.14 – 1.1.16]

2026-04-14 – 2026-04-18

UX Improvements

Draft hub as the root route

• The marketing splash page has been removed — the app now opens directly on the draft hub.
• Duplicate root routes and redirect loops cleaned up.

Pre-release set support

• Fully-spoiled pre-release sets now appear in the draft hub before their official release date.

Performance

• Draft hub client waterfall eliminated — data is now fetched in a single server-side pass.
• Booster count fetches parallelised with staggered starts to avoid thundering herd on set load.
• Commander deck loads moved from HTTP fetch to server action, removing a client round-trip.
• Billing snapshot prefetched on profile load; commander lookups cached.
• DB hasTable round-trips removed from the draft hot path; timeout increased.
• Turso Worker recycled on cold-start timeout to prevent stale connections accumulating.

Fixes

• Error boundary upgraded for Next.js 16 API (unstable_retry prop).
• Race condition fixed: concurrent LLM calls for set mechanics are now deduplicated.
• Turso worker timeout recovery and stale event guard added.
• Help and import guides added to the product documentation.

[1.1.13]

2026-04-12

UX Improvements

Core flow alignment

• Refocused the homepage around three primary product flows: Draft, Commander, and Standard.
• Demoted import and pricing into supporting navigation so utility screens no longer compete with the main product paths.
• Added clearer framing for which screens are primary destinations versus supporting tools.

Planning notes

• Added a documented COD-97 UI audit with prioritized follow-up cleanup items for the remaining page-by-page overhaul.
