v1.18.0-RC1

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.
