summary: >-
  Accela keeps a real, dated, continuously-maintained changelog for the Construct V4 API on the developer
  portal — 63 dated release entries running from the original May 2014 V4 release to August 2026, each naming
  a version number and listing new functionality and resolved issues, with affected endpoints named by URI.
  For a 2014-era enterprise API this is unusually good operational hygiene. What it does not have is any
  machine-readable form: no feed, no JSON, no per-entry anchor URLs — it is one long HTML page.

    date: '2026-08'
    breaking: false
    highlights:
      - >-
        Developer Portal registration became an approval workflow: the Registration button is now "Send
        Request", the new developer account is created disabled, and a human must enable it in the admin
        portal before it works. Materially changes time-to-first-call for a new integrator.
  - version: 4.6.5.3
    date: '2026-06'
    breaking: false
    highlights:
      - >-
        Per-app rate limits configured in the Agency Admin Portal are now actually enforced. Requests over the
        limit return HTTP 429 with X-RateLimit-Limit, X-RateLimit-Remaining and X-RateLimit-Reset. Before this
        release the configured limits were not enforced at all.
      - >-
        The Developer Portal Terms of Use page no longer requires a login to view.
      - >-
        Added an Agency Admin Portal setting controlling which agencies may access the Civic Data (Open Data)
        section.
  - version: 4.6.5

        method: GET

    highlights:
      - GET /v4/documents/{documentId}/thumbnail now honours the advised height and width parameters.
  - version: 4.6.4
    date: '2025-08'
    breaking: false
    highlights:
      - Resolved an internally discovered security vulnerability.
      - GET /v4/settings/drillDowns/ no longer fails when the parent value contains an ampersand.
      - Disabling a tenant now correctly rejects that tenant at oauth2/token.
  - version: 4.6.3.1
    date: '2025-07'
    breaking: false

      - path: /v4/gis/getParcels

      - path: /v4/gis/getAssets
        method: POST
    highlights:
      - Fixed intermittent HTTP 500 "Cannot access a disposed object" errors.
      - >-
        Authorization Code Flow without an agency in the URL now returns "The Agency is required" instead of
        the misleading "The environment is required".

        Carries a separate "Announcement of upcoming token changes" section — the closest thing in this
        changelog to a breaking-change notice.
