Summary

Adds a 90‑minute function timeout for asynchronous and event source mapping invocations on Lambda Managed Instances, a six‑fold increase over the previous 15‑minute limit.
Enables long‑running workloads such as media transcoding, AI inference, and financial simulations without architectural workarounds, and works with durable functions for up to 1‑year executions.
Configurable via the Lambda console, CLI, APIs, IaC tools, and the Agent Toolkit; synchronous invocations remain limited to 15 minutes.
