  Revision history tables published inside the EDXM FIX Order Entry and FIX
  Market Data Specifications (https://edxmarkets.com/vr-edx-markets/).
description: >-
  EDX Markets versions each connectivity specification independently with a
  document version (semver-style, e.g. Order Entry Specification v1.0.x) and a
  dated revision-history table inside the PDF. There is no single web changelog
  feed; the specification revision histories are the source of truth. This
  captures the recent window from the FIX Order Entry and Market Data specs.

  scheme: per-specification document version (semver-style) with dated revision history
