Bun runtime now supports large functions and extended max duration

Vercel's changelog announces that the Bun runtime now supports large functions and extended max duration. This means developers using Bun on Vercel can now deploy functions that are larger in size and can run for longer durations than previously allowed. The update is part of Vercel's ongoing enhancements to its serverless platform, specifically targeting the Bun runtime. The changelog does not specify exact size or duration limits, but the change is significant for developers who need to run more resource-intensive workloads or longer-running processes. This update is likely to be welcomed by the Bun community, as it removes previous constraints that may have limited the use of Bun for certain applications. Vercel's commitment to improving Bun support is evident in this update, which aligns with the growing popularity of Bun as a JavaScript runtime.
