PHP SDK 2.1.1
PHP workers now recognize an optional Server wake signal that prompts an immediate sweep of workflow, activity, and query tasks. This reduces mixed-kind idle polling latency when connected to Server 2.4.7 or later. Older Servers remain compatible and retain their existing polling behavior.
The full PHP, Laravel, Symfony, regression, and static-analysis checks passed. Published-artifact service-mode qualification with Server 2.4.7 remains to be recorded after that image is available.
