API Changes — v1.1.1

API changes from v1.1.0 to v1.1.1 that affect client code, one row per endpoint, grouped by API category. For a narrative summary of this release, see v1.1.1.

• API paths remain under /api/v1.
• Client Impact:
  • Breaking — existing integration code must change
  • Additive — new or backward-compatible
• Change types:
  • Added (new endpoint)
  • Removed (endpoint deleted, no direct replacement path — functionality moved to a different resource)
  • Path changed (same operation, new path)
• This page lists only endpoints impacted by v1.1.1 API changes. Container Management, Tunnels, Device Management (core CRUD), and Reports/Usage Jobs have no changes in v1.1.1. AI Model Management keeps every path and payload it had in v1.1.0, but the set of accepted deploy actions is narrower — see Improvements.
