## Action required

***

<Update label="October 6, 2026" tags={["Tracer", "Midaz"]}>
  ### [Tracer reservations use gRPC only in Midaz 4.2.0](/en/products/tracer/integration-guide)

  In Midaz 4.2.0, the Ledger reaches Tracer for reservations over gRPC only, on port 4021 by default. The REST reservation operations left the Tracer API reference. Deploy Tracer before the Ledger, and do not roll Tracer back below 4.2.0 while a 4.2.0 Ledger runs.
</Update>

<Update label="October 6, 2026" tags={["Pix"]}>
  ### [Pix JD v1.0.0 configuration and upgrade](/en/interfaces/pix-jd/pix-jd-environment-variables)

  The Pix JD pages moved to plugin release v1.0.0. In v1.0.0, the Midaz organization, ledger, asset and clearing account come from the systemplane binding and two `tenant_policy/midaz.*` keys, and payments and devoluções require `X-Idempotency`. Follow the new upgrade steps: write the `tenant_policy/midaz.*` keys first, then remove the retired `MIDAZ_*` identity variables.
</Update>

<Update label="October 6, 2026" tags={["Payments"]}>
  ### [Payments BTG bill payment flow and consult](/en/interfaces/payments-btg/boleto-and-bill-payment)

  The Payments BTG pages added the steps of a bill payment: the ledger reserves the funds before BTG receives the payment. An unknown outcome answers `202` with status `UNCONFIRMED`, the reference added a bill consult operation, and the error list added seven codes and removed `PBP-0209`. Do not resend an `UNCONFIRMED` payment under a new `Idempotency-Key`, and set `CONSULT_AUDIT_HMAC_KEY`: a pod that serves the payment API does not start without it.
</Update>

<Update label="October 6, 2026" tags={["TED"]}>
  ### [TED JD v3.0.1 error format](/en/reference/interfaces/ted-jd/ted-error-list)

  In TED JD v3.0.1, every error is an RFC 9457 problem document on `application/problem+json`, and a JD SPB code is on `upstream.code`. Update the error parsing of your integration.
</Update>

<Update label="October 6, 2026" tags={["SISBAJUD"]}>
  ### [SISBAJUD v1.2.0 license variables](/en/rails/sisbajud/sisbajud-environment-variables)

  Lerian SISBAJUD v1.2.0 needs `LICENSE_KEY` and `ORGANIZATION_IDS` in every environment. Set both variables.
</Update>

<Update label="October 6, 2026" tags={["Access Manager"]}>
  ### [Access Manager chart environment name](/en/platform/deploy/access-manager/access-manager-helm)

  The Access Manager Helm page added the environment name. The chart default is `development`. For any environment other than development, staging or local, expose Caradhras over https with a certificate from a public certificate authority. Then point Auth and Identity at that https address.
</Update>

<Update label="October 6, 2026" tags={["Streaming Hub"]}>
  ### [Streaming Hub v2.3.0 refusals](/en/reference/platform/streaming-hub/streaming-hub-error-list)

  In Streaming Hub v2.3.0, a `401` or `403` refusal is a problem document with code `unauthorized` or `forbidden`. The hub answers `503` when Access Manager returns no verdict. Update the error parsing of your integration.
</Update>

<Update label="October 6, 2026" tags={["Lerian Console"]}>
  ### [Lerian Console v2.6.0 pages](/en/platform/console/managing-applications)

  The Console pages changed to match Lerian Console v2.6.0. The update added pages for Reporter Institutions, TED IN operations, TED JD Accounting Routes and Pix BTG refunds, and covered report parameters and the `Partial failure` status. The update removed the BC Correios Console pages. The Console shows an application's client secret once, when you create the application. Store it then.
</Update>

<Update label="October 6, 2026" tags={["Pix", "TED"]}>
  ### [JD Courier](/en/interfaces/jd-courier/what-is-jd-courier)

  The Interfaces tab and the API Reference added JD Courier. JD Courier lets two or more core banking engines share one JD channel and one ISPB on SPB (TED) and Pix. It runs in BYOC and on Lerian Cloud.
</Update>

<Update label="October 6, 2026" tags={["Midaz"]}>
  ### [Fee debt in Midaz 4.2.0](/en/products/midaz/fees/fee-debt)

  In Midaz 4.2.0, the unpaid part of a deferrable fee on a `/v2` direct transaction can become a fee debt that later `/v2` credits settle, oldest first. Fee debt is off by default, and Valkey must persist its keys.
</Update>

<Update label="October 6, 2026" tags={["Access Manager"]}>
  ### [Access Manager Identity API reference](/en/reference/platform/access-manager/am-identity-apis)

  The Identity API reference dropped the partner, scope catalog and user tenant operations. The Access Manager error list added `IDE-0038`.
</Update>

<Update label="October 6, 2026" tags={["Consignado"]}>
  ### [Consignado v3.7.0](/en/rails/consignado/how-consignado-works)

  The Consignado API reference added an operation that reads the cadastro stored with an averbação, and the events reference changed to match what v3.7.0 emits. In Lerian Consignado v3.7.0, the saldo devedor sent to Dataprev is the present value of the unpaid installments.
</Update>

## No action

<Update label="October 6, 2026" tags={["SPI"]}>
  ### [SPI environment variables](/en/rails/spi/spi-environment-variables)
