v1.6.1CurrentAugust 2026

Native HTML→PDF (no Chromium for static docs)

  • ✓GST invoices and static html-to-pdf render in-process (Fulgur) — no Chromium spawn, no worker slot
  • ✓url-to-pdf, screenshots, and JS-driven HTML still use Chromium — warm process pool (new page per job, not a new Chrome)
  • ✓X-Sigli-Pdf-Engine: native | chromium on convert responses; PDF_ENGINE=auto|native|chromium
  • ✓Portal Convert pages spell out native vs Chromium and that volume belongs on the API / Batch, not the playground
  • ✓Pricing stays global — JSON invoice/certificate/receipt templates sit under html-pdf, not a region SKU
  • ✓Invoice PDF labels UPI vs e-invoice QR; sample VPA will not verify on GST apps. Certificate titles disable ligatures so “Certificate” extracts correctly
v1.6.2CurrentOctober 2026

Compliance extras

  • ✓Custom web fonts (WOFF2, WOFF, TTF, OTF) by URL or inline, embedded in the PDF
  • ✓Header/footer text slots with {page}, {pages}, {page:roman}, {date} and {title}, plus skip-first-page
  • ✓PDF/A-1b, 2b and 3b — on renders and for existing PDFs via POST /v1/pdf/pdfa, checked against veraPDF before it is returned
  • ✓Non-embedded Helvetica/Arial, Times and Courier swapped for metric-compatible fonts so third-party PDFs can be archived
  • ✓The encryption option now really encrypts (AES-256, print/copy permissions)
  • ✓UTF-8 is honoured for HTML without a charset tag — ₹, — and Indic text no longer turn into mojibake
v1.7.0CurrentOctober 2026

Metered Billing & Cost Controls

  • ✓Overage settles to Stripe as an invoice item when a billing period closes (workspaces billed through Stripe)
  • ✓Spend caps (including no-overage) and usage alerts at your thresholds, by email and the usage.threshold_reached webhook
  • ✓Seat limits for team plans, with extra seats purchasable
  • ✓Monthly usage & billing statements as CSV or PDF
