title: Instapage API Changelog
scheme: date
current_version: v1
format: dated entries grouped by Added / Changed / Improved, each naming the affected method + URL
note: >-
  The API changelog is a section of the single-page developer reference at devdocs.instapage.com,
  not a standalone feed. There is no RSS/Atom, no per-entry permalink and no version number attached
  to entries — the surface is versioned only as `v1` in the path, and every change below landed
  inside that version. No entry in the published window is marked breaking; the two removals are
  response-field removals for a page type Instapage retired from the product.
