description: >-
  SoFi Tech Solutions publishes a dated, monthly changelog on the Pro developer hub, with one
  entry per calendar month plus an annual year-in-review. Entries name the exact endpoints and
  fields that changed and link to the operation reference, which is materially more useful than
  a version bump. The index is machine-readable via the hub's llms.txt.

  cadence: monthly
  form: 'one page per month, slug <month>-<year>; annual "<year> Year in Review"'

current_version:
  program_api: '4.0'
  note: >-
    The changelog is not versioned - the Program API major version has been 4.0 throughout the
    published window. Change communication is by dated entry plus the Breaking Change Policy,
    not by semantic version.

    highlights:
      - >-
        Create ACH Transaction (post_createachtransaction) B2C debit classification sharpened -
        SEC code WEB for online/mobile authorization, other B2C defaulting to PPD.

    breaking: true
    breaking_note: >-
      companyEntryDesc became a REQUIRED field on Create ACH Transaction - by the provider's own
      Breaking Change Policy, "making a previously optional input field a required field" is a
      breaking change.
    additions:
      - New endpoint Get AutoPay Plan (post_getautopayplan) added to the Program API.
    highlights:
      - >-
        Set Overdraft Limit response field corrected to old_overdraft_limit (was documented as
        previous_overdraft_limit).
      - Get Overdraft Balance response field descriptions clarified, including ActualWithPrimary.
      - >-
        Service and Product RDF databases migrated - standardized columns for all clients,
        currency amounts now rendered as 15.0 rather than 15.00, and RDFs no longer split per
        prog_id / prod_id.
      - Outgoing ACH RDF confirmed to post empty files on weekends and bank holidays.
      - Reopened-case and TTI information added.
