Change history

Azure Functions limit changes

Current and previous observations remain linked to their official sources. Detection date and effective date are kept separate when known.

Verified history

No verified historical change is recorded yet.
This means HyperObserve has not found sufficient first-party evidence for a dated before-and-after event. It does not mean Azure Functions has never changed. Undated values are kept in the current baseline below instead of being presented as history.

Current monitored baseline

HyperObserve currently monitors 3 scoped observations for Azure Functions. The baseline covers hosting-plan execution timeout, HTTP load-balancer response ceiling, language worker startup. Each value retains its plan, product, endpoint, region, account, or runtime qualifier so a future change can be compared against the correct scope.

Tracked constraints and impact

Hosting-plan execution, HTTP response, startup, memory, and scaling constraints. A change is recorded only when it alters a constraint developers can act on, such as capacity planning, request shaping, model selection, deployment configuration, storage design, retry behavior, or account budgeting.

How a change is verified

  1. Compare the current first-party statement with the previously stored observation, including the exact plan, model, runtime, endpoint, region, and account scope.
  2. Separate a true product change from documentation clarification, temporary capacity, configurable account state, or a limit that applies to a different execution path.
  3. Preserve the old and new values, official source, effective date when disclosed, detection date, and practical impact. If those elements cannot be supported, no historical event is published.

Official sources monitored

These first-party documents support the current Azure Functions baseline. HyperObserve links directly to them so you can confirm the live wording before making a production decision.
