Ironfang changelog
What changed across Ironfang and its products, newest first: releases, new capabilities, moved addresses and renamed products, each with its date.
AddedIronfang Render
A certified connector for Power Automate and Power Apps
Ironfang Render is a Microsoft-certified Premium connector. Search for Ironfang Render when adding an action, connect it with an API key, and capture a screenshot, create a PDF, or start a render job and collect the file when it is ready.
AddedIronfang Render
The Render playground covers every option, and shows what a render found
The playground now sets lazy-content loading, success rules, custom PDF sizes, page ranges and document properties, and a page's language and clock without writing JSON, and its examples include a signed-in page, an invoice and a capture bundle. A playground result, a history record and a job each show what the page did: its status, how it settled, the language and clock it ran with, and any warnings explained.
AddedIronfang Render
Render in another language and time zone
locale (such as de-DE) and timezone (such as Europe/Berlin) set the browser's language and clock before the page's scripts run: date and number formatting, navigator.language, Accept-Language and local time, daylight saving included. They change what the page is told, not where the request comes from.
FixedIronfang Render
A durable job no longer runs twice at once
Since 12 October two job workers could pick up the same job at the same moment, so a job's page could be rendered twice. It was never charged twice. Each job is now taken by one worker at a time.
AddedIronfang Render
Capture bundles
One page load, the outputs you choose: a screenshot, the rendered HTML, the page's text, Markdown and its metadata, read together and returned with a manifest of what each output is, its size and SHA-256. A bundle counts one screenshot. Also as a job, in the portal and through the MCP server.
AddedIronfang Render
Custom PDF sizes, page ranges and document properties
PDFs take a custom page size with units (210mm, 8.5in), can let the page's own @page size decide, keep only the pages you name (1-3, 5, 8-), and carry a title, author, subject and keywords. A range that keeps no page is a 422 page_range_empty and is not charged.
AddedIronfang Render
Document templates
Store a PDF template once and render it with structured JSON data: loops, conditionals and a schema the data is checked against, with an editable draft and immutable numbered revisions you publish and roll back. Each document counts one PDF. In the API and the portal.
ChangedIronfang Render
Durable jobs take turns between accounts
Workers now pick the next job from the account running the fewest renders, oldest first within it, so one account's backlog no longer holds every worker while another account's job waits. Very large captures take turns too, so they cannot exhaust a browser between them.
AddedIronfang Render
Success rules: fail a render the page should not pass
success_rules say what should count as a failure rather than a picture: a status such as 404 or any 5xx, a missing element, text that must or must not be on the page, or a blank capture. A render a rule fails is a 422 success_rule_failed naming the rule, and is not charged.
AddedIronfang Render
Full-page captures can load lazy content first
full_page_readiness: scroll walks a full-page capture down the page before taking it, within a fixed budget, so images and sections that load as they come into view are in the picture. A capture that ran out of time or still had images loading says so in its warnings.
AddedIronfang Render
Every render says what it found
Renders report the page's own status and redirects, how it settled, the effective viewport and warnings such as height_capped or bot_challenge: as X-Ironfang-* headers on a synchronous render, and as diagnostics on jobs, their webhooks and request history. A 404 page captured successfully is now visibly a 404.
FixedIronfang Render
Transparent element captures and full-width capped pages
omit_background now applies to captures of a single element, not only to whole pages. A full-page capture cut at its height cap is as wide as the page's layout, so a phone capture is no longer 1280 pixels wide.
FixedIronfang Render
Template variables are text, and a wrong type says which
A number, boolean or object in a template's vars was refused with an unclear decoding error; it is now a 400 naming the variable and the type it got. Pass numbers as text. The TypeScript SDK 3.0.2 types vars as strings.
ChangedIronfang Analytics
The Ironfang Analytics snippet always loads the newest release
The install snippet now loads one address, https://analytics.ironfang.com/sdk/loader.js, which always serves the newest release, so you add it once and never change it to get a new one; a release reaches your pages within minutes. A snippet copied before today keeps working on the release it names: replace it with the one on your site's Installation tab to follow new releases.
AddedIronfang Analytics
How far behind a live replay is, in Ironfang Analytics
Watching a visitor live, the portal says how far behind them the picture is, such as "~2.4s behind": measured from their browser to yours, with the clocks compared through ours, and never shown more precisely than that allows. It says when the view is catching up, paused, reconnecting or stale, and you can pause it and go back to live; install snippet 0.8.0 reports the timing it needs.
AddedIronfang Analytics
Network and error diagnostics in Ironfang Analytics sessions
A session's Network view lists its requests with how each ended, including timeouts, aborts and answers the browser hides, and its Errors view its uncaught errors, unhandled rejections and console errors with their stacks and repeats, each linked to its moment in the replay. Each stream is a site setting, and what limits or sampling leave out is counted; install snippet 0.7.0 reports them.
ChangedIronfang Analytics
Ironfang Analytics: every recording belongs to a session
A site now follows sessions wherever it records, and can follow sessions without recording. Install snippet 0.6.1 records a visitor only inside their followed session, and pauseSession() keeps a page out of both.
AddedIronfang Analytics
Sessions in Ironfang Analytics
Every visit is now a session across all its tabs, with its journey, time on each page, uncaught errors, failed and slow requests and the moments you track, whether or not it was recorded. A session's recordings, replay and heatmap sit inside it, in the portal and the REST API; install snippet 0.6.0 reports them.
AddedIronfang Security
Continuous monitoring in Ironfang Security
Turn on monitoring for a verified domain and Ironfang runs the External Security Check on it every week, or every day if you choose. Each check is compared with the last: new, fixed and returning findings, severity changes, newly exposed services and certificates nearing expiry are shown in the portal, and the important ones are sent by email. Up to 3 monitored domains per organisation during the preview.
AddedIronfang Analytics
Heatmaps in Ironfang Analytics
See where visitors click, how far they scroll, what holds their attention and where the pointer rests on each page of your site, for desktop, tablet and mobile over the last 7, 30 or 90 days, drawn over the whole page as a real visitor saw it. They come from the recordings you already keep, with nothing more to install, in the portal and the REST API.
AddedIronfang Security
Ironfang Security: External Security Check, in preview
Scan verified domains for DNS, TLS, HTTP security header, cookie, email authentication and exposed service issues. Each finding includes evidence and steps to fix it, and can be rechecked on its own once fixed. Free during the preview. Automated and low impact: it attempts no exploitation or logins, and it is not a penetration test or a certification.
AddedIronfang Finance
242 validation rules explained
The rule reference explains 100 more rules, completing the Standard, Zero rated, Exempt, Reverse charge, Intra-community, Export and Not subject to VAT categories, the decimals rules and the Peppol exemption code pairings. Each comes with a recorded failing and corrected document.
RemovedIronfang Render, Ironfang Audit, Ironfang Finance
The Renderwolf, Auditwolf and Financewolf API names are retired
The /renderwolf, /auditwolf and /financewolf API prefixes now answer 410 Gone with the current address; use /render, /audit and /finance. Responses and webhooks carry only the X-Ironfang-* and Ironfang-* headers, MCP tools answer only to render.* and audit.*, and closing a Finance account takes DELETE FINANCE.
RemovedIronfang Render, Ironfang Finance
SDKs 2.0.0 drop the launch-era names
@ironfang/render and ironfang-render 2.0.0 no longer export Renderwolf or RenderwolfError or ship the ironfang_renderwolf module; @ironfang/finance and ironfang-finance 2.0.0 drop Financewolf, FinancewolfError, ironfang_financewolf, the financewolf command and FINANCEWOLF_API_KEY. Use the Ironfang names and IRONFANG_API_KEY.
DeprecatedIronfang Render, Ironfang Audit, Ironfang Finance
Response and webhook headers are named X-Ironfang-* and Ironfang-*
Responses carry X-Ironfang-Credits, X-Ironfang-Cache, X-Ironfang-Render-Ms and the rest, and webhooks are signed with Ironfang-Signature, Ironfang-Timestamp and Ironfang-Event-Id. The launch-era X-Renderwolf-*, X-Financewolf-* and Renderwolf-/Auditwolf-/Financewolf- headers are still sent alongside for now and will be removed; the SDKs (1.0.1), the CLI, render-action v1.2.0 and the n8n node 0.4.3 already read the new names.
ChangedPlatform
The MCP server is at mcp.ironfang.com
Point MCP clients at https://mcp.ironfang.com/mcp. The server is listed in the MCP Registry as com.ironfang/ironfang; the earlier uk.ironfang/ironfang entry is deprecated.
ChangedPlatform, Ironfang Render, Ironfang Finance
Clients call api.ironfang.com
New releases call the API at api.ironfang.com directly: the ironfang CLI 0.2.1, render-action v1.1.0, @ironfang/renderwolf 0.1.1, @ironfang/financewolf 0.2.1 and the n8n node 0.4.2. Upgrade older versions: HTTP clients drop the API key when they follow the redirect from api.ironfang.uk to another domain. The n8n node sends credentials saved with an ironfang.uk address to ironfang.com without any change to the workflow.
ChangedIronfang Render
The GitHub Action is ironfang-ltd/render-action
renderwolf-action is now render-action, v1.1.0, and @v1 points at it. Workflows that still say ironfang-ltd/renderwolf-action@v1 keep working: GitHub redirects the old name.
ChangedPlatform
Every service moved to ironfang.com
The API is at api.ironfang.com, sign-in at id.ironfang.com, the portal at portal.ironfang.com and the status page at status.ironfang.com. The ironfang.uk names redirect to their ironfang.com twins for a year; API calls should move now, because a redirect to another domain does not carry the API key.
ChangedPlatform
The website moved to ironfang.com
Every page of ironfang.uk now lives at the same path on ironfang.com, and the old addresses redirect permanently.
AddedPlatform
The site in German and French
Product pages, guides, the free tools, the legal pages and the Finance rule reference are published in German and French at /de and /fr, alongside English.
AddedIronfang Finance
Peppol BIS Billing 3 through the V2 API
The V2 validation API accepts Peppol BIS Billing 3 documents, on their own engine, beside XRechnung and ZUGFeRD / Factur-X.
AddedIronfang Finance
Finance SDKs 0.2.0: V2 validation
The TypeScript and Python clients, the CLI and the GitHub Action validate XRechnung and ZUGFeRD / Factur-X through V2, as XML or PDF.
AddedIronfang Finance
ZUGFeRD / Factur-X validation, XML or PDF
V2 validates ZUGFeRD / Factur-X 2.5.2 for the five base profiles, including hybrid PDFs: the invoice XML is extracted from the PDF and checked, and signed reports cover V2 results.
AddedIronfang Finance
142 validation rules explained
The rule reference explains 100 more rules, including warning rules, grouped into families you can scan.

Ironfang Test is now Ironfang Rig
The product was renamed, with its stateful mocks and fault injection: reordering, payload mutation, connection resets, bandwidth limits and partial responses.
ChangedPlatform, Ironfang Render, Ironfang Audit, Ironfang Finance
Renderwolf, Auditwolf and Financewolf are Ironfang Render, Audit and Finance
The products took the Ironfang name and their pages moved to /render, /audit and /finance. The old addresses redirect to the same page.
