api7/aisix 1.5.0 release date PR 1273 stream request metrics
💡 Result:
- **AISIX 1.5.0 release date:** **September 29, 2026**, according to API7’s release announcement. ([api7.ai](https://api7.ai/blog?utm_source=openai))
- **PR #1273:** merged **October 9, 2026**—after the 1.5.0 release. It fixes streaming request metrics so they’re recorded when the stream ends, with the terminal status and full-stream duration. Abandoned streams are reported as `499`; upstream failures use their failure status, such as `502` or `504`. It also unifies error-class naming across access logs and usage events. (GitHub pull request 1273 in api7/aisix (link omitted to avoid creating a cross-reference))
So **PR #1273 was not included in the original 1.5.0 release**; the sources show the PR merged later, but don’t establish which subsequent release contains it. (GitHub pull request 1273 in api7/aisix (link omitted to avoid creating a cross-reference))

Remove this note until appVersion points to an AISIX release containing api7/aisix#1273.
The chart defaults to AISIX 1.5.0, which predates the metric change. The note describes completion-time counting that the default image does not provide. During long-stream bursts, operators can therefore misinterpret the KEDA rate signal.

api7/aisix#1273 moved streamed responses to be counted in the request-family metrics,
aisix_llm_requests_totalincluded, when the stream ends instead of when the response head is written. The KEDA example incharts/aisixscales onsum(rate(aisix_llm_requests_total[2m])), so this adds a short note next to it (thekeda.triggerscomment invalues.yamland the "Autoscale on request load with KEDA" section of the README template): during a burst of long streams the signal lags by roughly one stream length, while the steady-state rate is unchanged. The example query itself stays as is.README.md is regenerated with helm-docs. No chart version or appVersion bump; this is held to ship with the chart release that carries the aisix version containing #1273.
