+Highlights:
+
+v1.18 release will bring a comprehensive rework of Local Activity Worker implementation
+- Local Activities now respect all the timeouts set on `LocalActivityOptions`.
+- Lower ScheduleToStart latencies for Local Activities and a backpressure that prefers retries over new executions
+- `LocalActivityOptions` got `scheduleToStart` timeout
+
+Migration note:
+Previously Local Activity Workers didn't respect `startToClose` and, in some cases, `scheduleToClose` timeouts.
+Some users may have `LocalActivityOptions` configurations that don't accommodate their actual timings but previously were unenforced.
+The enforcement will kick in after an upgrade on v1.18+ and may lead to Local Activity failures that were not happening before.
+Users may need to test and adjust their `LocalActivityOptions` timeouts before rolling out v1.18+ to production.
