[1.2.18] - 2026-03-30

Frontend

Added

• Themed HTML 404 page - Added a branded browser-facing 404 page with noindex metadata, localized navigation shortcuts, and direct rendering for unknown public HTML routes instead of JSON fallback responses

Changed

• Canonical public-page normalization - Public HTML routes now use explicit canonical redirects for language roots and trailing-slash variants so crawler-facing URLs stay stable across home, configure, stats, changelog, privacy, and API docs pages
• Favicon asset serving - Replaced the inline SVG emoji favicon with the packaged ICO asset so browser and audit tooling both see the same icon resource referenced by the site manifest and HTML head
• 404 and credits localization polish - Localized the new 404 page copy across all supported languages, regrouped homepage credits into a stable responsive layout, and aligned site/README acknowledgements for weather data, weather icons, analytics, monitoring, flag assets, and inspiration sources
• Homepage and mobile-nav polish - Refined the homepage credits presentation, removed the desktop header credits dropdown, moved mobile credits into the drawer footer, and tightened mobile header spacing so the logo, menu button, and language switcher stay balanced across breakpoints
• Language selector labels - Shortened the visible PT-BR and ZH-CN language labels to compact PT and ZH display text while keeping the underlying locale routing unchanged
• Header and drawer navigation cleanup - Restored the smaller desktop logo/header balance, simplified the language switcher label treatment, and tuned the mobile drawer so navigation remains at the top while credits stay anchored in a compact footer block
• Credits naming and layout sync - Renamed credits entries to the current public wording (Inspiration, Jolpica-F1 API, Weather-icons, Devices) and aligned mobile drawer credits into consistent label/value rows with inline device and hosting pairs
• README cleanup - Removed decorative emoji section headings and refreshed credits/documentation copy so the public project page matches the current app behavior and deployment requirements

Backend

Changed

• Proxy-aware canonical redirects - Disabled FastAPI's implicit slash redirects, added explicit 301 route normalizers, and taught the app/runtime to respect forwarded proxy headers so HTTPS canonical redirects no longer downgrade to http behind Coolify/Traefik
• Canonical host enforcement - Added www to apex redirect handling in middleware, hardened host parsing for non-default SITE_URL ports, and now emit HSTS on both normal HTTPS responses and the www redirect itself
• Trusted proxy defaults - Switched the container startup command to a configurable FORWARDED_ALLOW_IPS allowlist with private-network defaults, keeping proxy header trust adjustable per deployment instead of unconditional *
• Startup config centralization - Moved FORWARDED_ALLOW_IPS and SKIP_PERSISTENCE_CHECK into app/config.py so runtime defaults and environment loading stay in one configuration path

Fixed

• Crawler and SEO endpoint coverage - Added regression tests for robots.txt, sitemap.xml, canonical redirects, HTML 404 rendering, HSTS behavior, favicon responses, and HTTPS-only redirect assertions so the Search Console remediation work stays locked to the configured canonical host

Documentation

Changed

• Deployment env guidance - Added missing required environment variables to the example env files and clarified that SITE_URL controls canonical URLs, Open Graph tags, robots.txt, sitemap.xml, and www canonicalization while ANALYTICS_HOSTNAME only affects analytics
• Coolify apex redirect recipe - Documented the production-ready Traefik and Caddy label setup for single-hop http://www -> https://apex canonical redirects on self-hosted Coolify deployments

[1.2.17] - 2026-03-29

Frontend

Added

• Top-10 locale expansion - Added localized site/UI coverage for de, es, fr, it, nl, pl, pt-BR, tr, ja, zh-CN, and sk, including locale metadata, alphabetized language selectors, and shared frontend locale handling

Changed

• Localized configure/docs source-of-truth - Moved configure-page UI copy into the shared translation files, injected canonical locale codes into shared frontend helpers, aligned language switching/redirect behavior with the current route and query string, and updated localized HTML API docs to expose the full supported language set
• README and public docs refresh - Updated README/examples/self-hosting guidance to match the current localized configure flow, teams endpoints, startup warmup behavior, generated localized preview assets, and API docs examples that now use the active request host instead of placeholder domains
• Track artwork refresh - Added new Miami, Albert Park, and Shanghai track source/variant assets for all supported display modes, including PSD source files for future edits

Backend

Changed

• Localized asset generation and startup warmup - Expanded scheduled/startup generation to cover all configured locales for calendar and teams assets, kept timezone-specific calendar generation for popular non-default TZs, moved version refresh to hourly :05, and warmed teams render assets on startup to cut cold-start render latency
• Pregenerated localized image serving - /calendar.bmp and /teams.bmp now reuse pregenerated localized assets across all supported locales instead of special-casing only en/cs

Fixed

• Localized page consistency - Fixed localized configure/API docs routes, corrected og:locale metadata, aligned shared locale lists across backend/frontend, and localized configure race/session copy so non-en/cs pages no longer fall back to stale English strings
• Renderer and preview reliability - Added locale-aware CJK font coverage to image rendering, fit long translated schedule labels, shortened sprint qualifying schedule labels per locale, kept CJK teams driver names clear of the team-card header, restored teams previews/static loading paths, disabled invalid FastAPI preview response-model inference, and reused scheduler preview data across languages to avoid redundant fetches
• Teams rendering polish - Limited the CJK font override on teams screens to the translated header subtitle, kept the lower team cards on the brand font, and normalized Red Bull / Racing Bulls power-unit labels down to RB ... variants
• Teams configure resiliency - Fixed Season Leaders/teams configure loading regressions caused by page-specific JS assumptions and made teams previews prefer pregenerated localized PNGs with dynamic fallback
• Security and release validation follow-ups - Removed unsafe innerHTML usage from the ePaper setup flow, hardened client-side language redirects, fixed DeepSource validator findings, and kept changelog/release validation metadata in sync for release-readiness checks
• Image key consistency - Hardened pregenerated image-key helpers to reject unsupported display modes and aligned teams route cache keys with the shared scheduler/pregeneration key format

[1.2.16] - 2026-03-25

Backend

Fixed

• Cancelled season refresh persistence - Static season updates now preserve previously tracked cancelled races such as Bahrain and Jeddah when Jolpica omits them, and season JSON refreshes now end with a trailing newline for cleaner diffs and POSIX-friendly tooling

[1.2.15] - 2026-03-24

Frontend

Added

• Teams display parity - Added 1bit, B/W/R, B/W/R/Y, and Spectra 6 variants to the teams configure flow, previews, API docs, and a dedicated teams display breakdown in the stats dashboard
• Display-aware session accents - Multi-color calendar outputs now color Race, Qualifying, Sprint, and Practice labels according to the active display palette, with unsupported colors falling back to black
• SVERIO hardware docs - Added SVERIO B/W/R/Y PaperBoard hardware references to the site credits/README and documented a tested 7.5" GDEM075F52 screenshot placeholder for the four-color panel

Backend

Added

• Teams display renderers - Extended /teams.bmp to support the same display selection flow as /calendar.bmp, including color-aware teams rendering, per-display preview generation, analytics tagging, and scheduler/configure preview generation for all display modes

Fixed

• Teams logo/render polish - Refined logo sourcing and 1-bit/logo conversion behavior across teams renderers, added dedicated 1-bit overrides for problematic team marks, preserved half-points in standings output, and treated legacy teams analytics rows without display_type as 1bit
• Teams header layout - Reworked the team-card header stats area into a shared aligned panel, improved vertical/horizontal centering, right-aligned points across teams, highlighted the leading constructor position in color-capable displays, and improved B/W/R and B/W/R/Y meta-text readability
• Teams row alignment - Fixed driver-name column alignment by anchoring names to a shared slot, centering driver numbers inside that slot, and keeping spacing consistent across mixed-width number/photo assets
• Sauber logo fallback - Non-Spectra 6 teams renders now remap Sauber's green accent to a mono-friendly white-on-black mark so 1bit, B/W/R, and B/W/R/Y variants stay legible in 2024/2025 layouts
• Calendar session color mapping - Spectra 6 now uses red/yellow/green/blue accents for Race/Qualifying/Sprint/Practice, while B/W/R and B/W/R/Y gracefully fall back to supported palette colors
• Benchmark and quality follow-ups - Lazy-loaded teams assets for the 1-bit renderer to avoid unrelated benchmark regressions, restored CodSpeed to the GitHub-hosted runner, resolved DeepSource findings (including helper visibility/static-method cleanup), and split complex team-row renderer methods into smaller helpers
• Documentation sync - Updated README/examples/self-hosting/BMP pipeline docs so public documentation matches the current endpoints, display variants, generated preview naming, and teams rendering behavior

[1.2.14] - 2026-03-19

Frontend

Changed

• Configure cleanup - Split the shared configure screen into calendar/teams partials, removed dead teams timezone controls, renamed the teams side panel to Season Leaders, and tightened the mobile sidebar layout with compact display mode labels (B/W, B/W/R, B/W/R/Y, 6C)
• Stats dashboard polish - Unified breakdown color ranking across cards, widened the display breakdown, clarified range/fallback copy, shortened mobile race labels to GP, and kept percentage bars aligned while preserving a visible white lowest-rank bar

Backend

Changed

• Stats shaping cleanup - Removed unused display color metadata and dropped unused performance dashboard queries from the stats page route while keeping localized range labels in the rendered context

Fixed

• Race stats aggregation - Combined auto-selected and manually selected requests for the same race into a single breakdown row while retaining an auto_selected_count signal for display hints

[1.2.13] - 2026-03-17

Frontend

Added

• B/W/R/Y display mode - Added display=bwry to the calendar configure UI, preview routing, API docs, and stats labeling for the four-color calendar output

Backend

Added

• B/W/R/Y renderer pipeline - Added dedicated bwry calendar rendering, scheduler generation, track/flag preprocessing scripts, and calendar API support alongside existing 1bit, bwr, and spectra6 modes

Fixed

• SEO: lightweight HTML HEAD responses - Public HTML page routes now short-circuit HEAD requests before analytics or stats queries, preventing 405 responses in Search Console without adding crawler-only pageview noise or extra DB load

[1.2.12] - 2026-03-16

Frontend

Changed

• Track asset variants - Track rendering now prefers display-specific source assets like _bw, _bwr, and _spectra6, with the plain circuit PNG kept as the generic fallback and _bwry naming prepared for future display support
• Track render quality - 1bit, B/W/R, and Spectra 6 track maps now prefer source artwork over preprocessed BMP fallbacks so resized text and thin lines stay sharper in the final composed image
• Display palettes - B/W/R now uses a vivid pure red palette and Spectra 6 now uses more vivid red/yellow/green/blue output colors to better match the prepared source artwork
• BMP pipeline docs - Added a dedicated BMP_PROCESSING.md guide that documents the current source naming, preprocessing steps, fallback order, and final BMP encoding flow for all active and prepared display variants

Backend

Removed

• main -> dev sync automation - Removed the post-release sync workflow and retired the dedicated dev branch maintenance flow

Changed

• Track preprocessing scripts - Added explicit preprocessing flows for spectra6 and prepared bwry track assets, and aligned runtime/source resolution around per-display source variants with generic fallback assets

Fixed

• Post-merge quality issues - Added Open-Meteo config validation at startup, cleaned up DeepSource-reported service/test patterns, and documented the safe 0.0.0.0 bind used for container deployments
• Cancelled race persistence - Season API responses now merge cancelled races back in from static season JSON when Jolpica omits them entirely, so removed Bahrain/Jeddah weekends still appear at the end of the calendar as cancelled entries

[1.2.11] - 2026-03-16

Frontend

Changed

• Cancelled race selection - Configure UI now keeps cancelled weekends at the end of the season list, highlights them in red, and lets previews request them via stable race_key identifiers

Backend

Changed

• F1 data automation - Scheduled Update F1 Data runs now refresh both historical circuit results and static season calendar JSON files under app/assets/seasons/

Fixed

• Race status rendering - /calendar.bmp keeps cancelled races addressable without breaking existing year + round requests, skips weather fetches for cancelled weekends, renders a centered CANCELLED/ZRUŠENO label in the countdown slot, and now shows IN PROGRESS/PROBÍHÁ for the first three hours after lights out before switching to COMPLETED/DOKONČEN

[1.2.10] - 2026-03-13

Frontend

Added

• Stats display breakdown - Added a new statistics card that shows calendar request share by 1bit, B/W/R, and Spectra 6 display type

Backend

• Display type analytics - Persisted calendar display mode in API call statistics so the stats dashboard can aggregate usage by display type

• Spectra 6 track bitmap - Updated tracks_spectra6/albert_park.bmp to match the refreshed Albert Park circuit source
• Release sync automation - Updated release and sync workflows to publish releases with SYNC_PAT, trigger main-to-dev sync after published releases, and record the synced main SHA in the automation PR

[1.2.7] - 2026-03-09

Frontend

Fixed

• Teams & Drivers preview - Corrected 2026 team ordering, standings placement, right-aligned logos, and season selector behavior so the configure preview matches the live championship layout
• Driver number rendering - Switched teams.bmp to render cleaner font-based driver numbers instead of relying on stale number image assets

Backend

Fixed

• 2026 teams bitmap data - Added curated 2026 team data, corrected driver numbers, and normalized override handling so live and static team renders stay in sync
• Teams bitmap rendering - Team logos now support Audi and Cadillac, constructor standings render in the correct order for 11-team 2026 grids, and team header layout avoids collisions with standings and driver names
• Teams bitmap freshness - /teams.bmp now disables long-lived HTTP caching so lineup and standings changes appear immediately after deploys
• Teams data matching - Driver standings merging now tolerates ASCII/diacritic name differences and sponsor-prefixed constructor names such as Perez/Pérez, Hulkenberg/Hülkenberg, and Atlassian Williams/Williams

Added

• 2026 regression coverage - Added renderer and teams-service tests for 2026 team data, manual driver-number overrides, and full BMP rendering in English and Czech
