July 7, 2026 Documentation update Review recommended

​
Affects

Teams that use Matcher for reconciliation — operators uploading and mapping statements, teams building match rules, and anyone integrating external data sources or bank aggregators. The Console experience changes visually for all users, and several new capabilities become available through the API and the Console. This release includes both new product behavior and documentation updates. It applies across deployment models; no SaaS-only or BYOC-only behavior is introduced.

​
What changed

​
AI-assisted ingestion and mapping

Matcher adds AI-assisted document extraction, field mapping-proposal assist, and match-rule suggestions. Each flows through a human-in-the-loop review step, so proposed extractions, mappings, and rules are surfaced for an operator to approve, edit, or reject before they take effect. Nothing is applied automatically without review.

​
New discovery-connector platform

A connector platform is now available for onboarding sources: bank and data aggregators (Pluggy, Belvo), file formats (CNAB240, CNAB400, OFX, camt.053 preview), and SFTP transport. A discovery endpoint lists the supported connector types, and operators can configure connections and per-source webhooks self-serve.

​
Standardized API error responses

API error responses are now returned as a consistent problem shape, making failures easier to parse and handle programmatically. Before 
{
  "error": "invalid connector type"
}
After 
{
  "type": "https://errors.lerian.studio/matcher/connector-type-invalid",
  "title": "Connector type is not supported",
  "status": 422,
  "detail": "The connector type 'xyz' is not in the supported catalog.",
  "field": "connectorType"
}

​
Console rebrand

The Matcher Console adopts the new enterprise ink-blue theme. Layout and navigation are refreshed (breadcrumbs, context-scoped sidebar, command palette), while existing workflows remain in place.

​
Reliability fixes

This release resolves seven customer-facing issues, including corrected dashboard statistics (“dashboard truth”), manual-match behavior, file upload handling, resolution attribution on matched items, and match list ordering.

​
Impact

This is a behavior-changing release. It introduces new endpoints and capabilities (AI extraction, mapping and rule suggestions, discovery connectors), changes the API error response shape, and updates the Console appearance and navigation. Classification: Review recommended. No migration is required and existing integrations continue to work, but you should review the new capabilities and confirm that any client code parsing Matcher error responses handles the standardized problem shape.

​
What you need to do

1
Review the AI extraction, mapping-proposal, and match-rule suggestion flows, and decide who owns the human-in-the-loop approval step.
2
If you onboard sources via aggregators or files, explore the new discovery connectors (Pluggy, Belvo, CNAB, OFX, SFTP, camt.053) and configure connections as needed.
3
Confirm that any code that parses Matcher API error responses handles the standardized problem shape (type, title, status, detail).
4
Let operators know the Console has a new ink-blue look and refreshed navigation; workflows are unchanged.

​
Deadline

None. No action is required to keep your integration working. Review is recommended before relying on the new capabilities.

​
Why

To let teams onboard and map sources faster with AI assistance while keeping a human approval step, to broaden the range of supported connectors and file formats, to make API error handling consistent and predictable, and to align the Matcher Console with the current Lerian design system.
