v2.0.0 — anyplot.ai Relaunch

The project rebrands from pyplots.ai to anyplot.ai, ships a redesigned homepage, a new Okabe-Ito color palette, and first-class dark mode for both the site and every plot preview. This is a major release because URLs, the database schema, and the public domain all change.

⚠️ Breaking changes — Update bookmarks to https://anyplot.ai. The old pyplots.ai domain now redirects, but the spec URL structure changed: see "URL restructure" below.

Highlights

🎨 New homepage & visual identity

• Full landing-page redesign: hero, libraries section, palette section, specifications/featured-examples grid, palette swatches, masthead rule, science note (#1ecf700b, #f12d08ce, #d439ebe6, #f095287c, #d7ea3d00, #db013c7d).
• Clickable Plot of the Day with GitHub source link and tagline (#fed6fec4).
• All pages unified under the landing-page style with mobile overhaul (#49119d96, #b3df441f).
• New typography doctrine: MonoLisa-only across the site (#1ecf700b, #7cfd7fc6).
• New Okabe-Ito colorblind-safe palette with theme-adaptive chrome (#1d46297b).

🌗 Dark mode (site + plots)

• Theme toggle with prefers-color-scheme detection and persistence.
• Backend renders dual-theme previews — every plot ships plot-light.png and plot-dark.png (plot-light.html / plot-dark.html for interactive libraries) (#0f1a9946).
• Theme-aware preview selection across the API and frontend (#e5bb5a81), with mandatory theme-readability review in the AI quality pipeline.
• Theme tokens (--ink, --rule, --bg-*) drive all chrome; CSS code-block colors fixed for both modes (#edc93f52, #c3463e43).

🌍 Rebrand: pyplots.ai → anyplot.ai

• Domain migration with nginx fixes for redirect loops (#bd4cee15, #1a20d1c5, #13a52c32, #ee32a0dc, #fec16a78, #32a933d1).
• Repository, MCP server, READMEs, and all in-app references updated.

🔗 URL restructure (breaking)

• New canonical spec URL: /{specId}/{language}/{library} (#e24a7cd7, PR #5289).
• Hub view consolidated: /{specId} with optional ?language= filter (#129e10cf, PR #5297).
• Catalog → Plots rename (#4be4cc0f, #2ad0d725).
• Old paths return a NotFoundPage instead of looping redirects (#fec16a78, #32a933d1).

🗄️ Schema changes (breaking)

• Multi-language path restructure with new languages table (#306d5ba1).
• Implementations now expose preview_url_light / preview_url_dark; the legacy preview_url is a synonym for the light variant (#0f1a9946, #e5bb5a81, #3b51f66d).
• Related-specs endpoint also returns themed URLs (#3b51f66d).

Frontend

• New components: NavBar, HeroSection, LibrariesSection, LibraryCard, PaletteStrip, NumbersStrip, MastheadRule, ScienceNote, SectionHeader, PlotOfTheDayTerminal, ThemeToggle, RootLayout, BareLayout, RouteErrorBoundary, TypewriterText (#74d98414, #d7e46ead, #fed6fec4, #4be4cc0f).
• New pages: LandingPage, LibrariesPage, PalettePage, AboutPage, NotFoundPage, SpecsListPage (#d439ebe6, #f095287c).
• Route-level error boundary with chunk-reload recovery for stale deploys (#f52e97c8, PR #5298).
• ImageCard and grid now respect dark mode (last two patches in this branch — 8e9a8cf3, 3b51f66d).
• Pseudo-function style applied consistently across the frontend (#28e94693, PR #5293).
• MUI bumped from v7 to v9, with FilterBar breaking-change fixes (#66a3fe94, #3dd2acaf).

Backend / API

• Theme-aware preview selection in spec, implementation, related-specs, and POTD endpoints (#e5bb5a81, #3b51f66d).
• API in-memory cache invalidation after sync-postgres (#ef0512be).
• Sync triggers now include alembic versions/ (#6101bd4a).
• Cloudflare bypass on cache-invalidate; created timestamps preserved across regenerations (#c8921b95, #7a33c0db).
• Preview URL migration to the anyplot-images GCS bucket (#f37ebbdc).

CI / infrastructure

• 6 workflows migrated from service-account keys to Workload Identity Federation (#1cdb8b94).
• Bulk-generate moved to paced sequential dispatch with a global mutex (#407d34ab, #5e40a57f).
• Daily cron regenerates the oldest not-recently-updated spec (#a3af50c4); shifted to a 4h cadence with a Berlin-evening blackout (#94ad42b2).
• Mandatory dual-theme rendering and readability checks in the impl-generate / impl-review pipeline (#0f1a9946).
• allowed_bots='*' set on the Claude action (#62c8c80a).
• nginx: stop caching /public static files as 1y immutable (#ea0b1015).

Plots

• New specs added: scatter-lag, upset-basic, bar-spine, bar-3d-categorical, network-bipartite, map-tilegrid, dendrogram-radial, heatmap-polar, spiral-timeseries, diagnostic-regression-panel, dot-matrix-proportional, heatmap-adjacency, area-cumulative-flow, ice-basic, shap-waterfall, scatter-embedding.
• Implementations across all 9 libraries for scatter-lag and scatter-basic regenerated under the new dual-theme pipeline (#5268–#5276, #5300, #5308–#5315, #5318).

Quality / tooling

• Comprehensive frontend & backend test suite expansion (#3b18c56e, PR #5277).
• WCAG-AA contrast pass for dark-mode adaptive chrome (#c3463e43).
• Style-guide synced with the landing-page rollout and mobile patterns (#9fc72a27, #966bc650, #3e73e450).
• Dependency bumps: MUI 7→9, React group, Vite 7→8, FastMCP v3, FastAPI 0.136, anthropic 0.97, SQLAlchemy 2.0.49, uvicorn 0.44, plus minor security bumps for cryptography/mako/authlib/python-multipart (#66a3fe94, #46cbe725, #44f47013, #6e2e82db, #eaf03fbe, #132a0ebe, #5bda5bb2, #76837a9f, #a3c5e059, #d438ff53, #77d1b824).

Migration notes

• Bookmarks: https://pyplots.ai/... is gone; use https://anyplot.ai/....
• Spec URLs: deep links to old /specs/{id}/{library} paths should be updated to /{specId}/{language}/{library} (e.g. /scatter-basic/python/matplotlib).
• MCP clients: point your config at the new anyplot.ai endpoint.
• API consumers: prefer the new preview_url_light / preview_url_dark fields; the legacy preview_url keeps working as the light variant.
