v1.8.0 2026-05-20 · current

Symbol Builder — 4-language UI, more shapes, dedicated free page

New
  • Dedicated Symbol Builder page — an indexable landing for the free online editor, with FAQ and a direct deep-link into the tool.
  • 5 new shapes + a flow arrow: star, parallelogram, trapezoid, cross and double-arrow, plus an ISA flow-direction arrow.
  • Category filter for catalog stamps inside the builder (motor, valve, pump…), and starter examples to skip the blank canvas.
  • Export background option (transparent / HMI gray / white), Copy SVG, and flip H/V.
Improved
  • The whole catalog + builder UI now follows your language (EN / ES / PT / FR): topbar, palette, properties, templates, toasts, toolbar, demo banner and detail modal.
  • The builder is usable with no account — free with a watermark, with a clear path to clean, watermark-free exports.
  • Promoted the builder across the site (nav, hero, footer) and added SEO metadata + WebApplication / FAQPage structured data.
Fixed
  • Symbol-count consistency — a few pages still said "300+/750+"; now uniformly "900+".
  • A builder modal overlay that could intercept clicks, and a templates/empty-state visual collision.
v1.7.0 2026-05-20

Symbol Builder — compose your own symbols from shapes + catalog parts

New
  • Symbol Builder (beta): a vanilla, offline composer inside the catalog. Open it from the toolbar ("Build your own") or land straight in it via /catalogo/?builder=1.
  • Building blocks: 11 ISA shape primitives (rectangle, rounded, circle, ellipse, triangle, diamond, hexagon, N-gon, line, arrow, text), instrument bubbles (field / DCS / PLC / shared), connection lines (process / electrical / signal), plus any catalog symbol dropped in as a "stamp".
  • Editing: move, resize (8 handles), rotate, flip, snap-to-grid, recolor with the ISA-101 palette, stroke / opacity / corner radius, layers, group, duplicate, align, z-order, undo/redo, and arrow-key nudge.
  • Save & reuse: named templates in your browser, shareable build links, and export to PNG / SVG — clean on paid plans, watermarked on Demo.
  • Starter examples to skip the blank canvas: instrument loop, tagged motor, labeled valve.
Improved
  • Hardened backend trigger functions per the Supabase security advisor — removed needless RPC executability of the signup helper and pinned a mutable search_path. No user-facing change.
v1.6.0 2026-04-28

Sweep release — bugs squashed, cross-linking, perf, a11y

Fixed
  • TOC component never appeared on any long-form page (TDZ ReferenceError: Cannot access 'TOC_CSS' before initialization). Restored across all 18 pages.
  • Featured showcase strip on the catalog rendered as a single 256 px-wide grid cell (1 column) instead of spanning the full main area. Now correctly mounted outside the catalog grid as a sibling.
  • Catalog hotkey conflict: typing into the search bar accidentally toggled "P&ID canonical only" or jumped category. Hotkeys now bail on editable focus; Esc still works inside the search input.
  • Catalog deep-link ?filter=canonical targeted the wrong checkbox ID and silently failed. Fixed.
  • FactoryTalk integration guide had a stray </p> closing tag and the sizing table referenced "WinCC pack" / "Weintek pack" instead of "FactoryTalk pack".
  • Weintek integration guide referenced a fictional cmt-graphics-svg path; replaced with the real .flb User Library mechanism.
  • 8 broken catalog deep-links from industry pages — kinds like centrifugal_blower, brew_kettle, fermenter, filter-cartridge didn't exist in the catalog. Re-mapped to closest canonical kinds.
  • Privacy page mentioned an EU region inconsistent with security.html and an outdated Privacy Shield reference. Both removed.
Improved
  • React production build served instead of react.development on the landing — major perceived-perf bump.
  • Hardcoded Spanish strings in the React app + dashboard removed. Site is now fully English on every public surface.
  • FAQ now has equal coverage in es / pt / fr (10 questions matching the EN version) — non-EN visitors no longer hit a half-empty FAQ.
  • Aria-labels and roles added to icon buttons, dropdown menus, and modals across the React app.
  • Glossary +3 terms: BPCS, HART, Alarm flood (with cross-references). DefinedTermSet JSON-LD expanded.
  • Article TOC component is more robust: IntersectionObserver feature-check, slug collision avoidance, MediaQueryList legacy listener fallback (Safari < 14), graceful empty-state when no anchors visible.
  • Long-form articles cross-link to /integrations/ and /industries/ in their "Keep reading" sections — better internal-link graph for SEO.
  • Catalog: empty state message in English with a "Clear all filters" button.
v1.5.0 2026-04-28

Stitch batch 7-final — 21 new canonical symbols

New
  • Equipment with full 9-state matrix: DC motor canonical (M with horizontal bar), servo motor with rear-mounted encoder, definitive centrifugal pump (motor + coupling + volute + impeller cue + suction/discharge flanges), rectangular slide gate.
  • 6 alarm badges with explicit geometric shapes: P1 triangle, P2 diamond, P3 hexagon, P4 circle, acknowledged (green checkmark), suppressed (bell with diagonal slash).
  • 5 ISA-5.1 instrument bubbles (empty shells for tag overlay): field-mounted, DCS-shared, PLC, shared display, logic diamond.
  • 6 ISA-5.1 connection line styles: process pipe with flanges, electrical zigzag, pneumatic forward slashes, hydraulic back slashes, capillary X marks, data link long-short dash pattern.
Improved
  • Featured showcase: pump_centrif_final replaces older end-suction representative; servo motor and slide gate added as canonical examples.
  • All 21 symbols visually audited before integration — every <g id="body|accessories|connections"> follows the standard structure for CFG-aware re-coloring.
v1.4.0 2026-04-27

Glossary, Learn hub, dedicated About / Security pages

New
  • 30-term HMI / SCADA / P&ID glossary with cross-references and JSON-LD DefinedTermSet structured data.
  • Newsletter signup component in the footer (writes to leads with source newsletter_footer).
  • /changelog.html — this page (was previously linking to GitHub releases).
  • Learn hub landing page collecting standards refs and practitioner guides.
  • About page — who we are, what we believe, where we ship from.
  • Security & compliance page — GDPR, subprocessors, data residency, vulnerability disclosure.
  • Footer newsletter signup (one short email a month, no spam).
Improved
  • Pricing toggle: bigger hit target, "Save 2 months" annotation arrow, dark active state for clearer affordance.
  • Catalog: real <nav> breadcrumb (Home / Catalog) plus BreadcrumbList JSON-LD.
  • Open Graph and Twitter Card meta tags on every long-form page (standards, learn, about, security, changelog).
  • Mobile responsive sweep at 480px and 360px: catalog single column, modals fit in viewport, comparison table scrolls.
v1.3.0 2026-04-22

Commercial polish — vendor logos, "How it works", FAQ overhaul

New
  • Vendor compatibility strip on the home page (Weintek, Siemens, Rockwell, Inductive, Schneider, AVEVA).
  • "How it works" 3-step section with realistic timing (browse → configure → export to PLC).
  • 10-question FAQ (commercial focus) with FAQPage JSON-LD for rich results.
  • Comparison table: ISA-101 calm palette · live editor · 9-state matrix rows added.
Improved
  • Signup form simplified: 4 → 3 fields. Company info collected later from the dashboard.
  • Dashboard onboarding card for first-time users.
  • Footer reorganized into Product / Resources / Company columns with rich anchor text.
v1.2.0 2026-04-15

Catalog UX — lazy load, detail modal, hotkeys, featured showcase

New
  • Detail modal (click any card): preview at scale, copy SVG / PNG to clipboard, see all 9 states.
  • Keyboard shortcuts: 1-9 jump to category, 0 show all, F toggle "P&ID canonical only", / focus search, Esc close modal.
  • "Only P&ID canonical" filter — surfaces the standards-conforming symbols above stylized variants.
  • Featured showcase row: hand-picked canonical symbols at the top of the grid.
Improved
  • Lazy-load with IntersectionObserver: 949 cards render smoothly on low-end devices.
  • Sidebar v3: Style preset dropdown (7 vendor palettes), tag-prefix override, layout density, save/load JSON config.
  • Canonical P&ID symbols (motor, pump, valve, fan, compressor) appear first in each category.
Fixed
  • CFG-aware coloring helper applied uniformly across all generated SVG templates.
  • Stylized motor-servo and motor-DC variants removed — they did not match canonical P&ID and confused the catalog.
