S3 Not Shown in Protocol List

I am following the instructions on the following page to setup transfer to AWS S3 bucket.

https://winscp.net/eng/docs/guide_amazon_s3

When I start WinSCP and get the Login box, I select New Site node on the left. When I check the Protocol drop-down, I only have SFTP, SCP, FTP and WebDAV. I don't see Amazon S3 as an option.

I am currently running version 5.11.3 (Build 7995). When I do a Check for Updates, it says I have the latest version.

Thanks!

PS - Nevermind. Upon digging a little more, I see that S3 is only available in the beta. Downloading now.

Is beta another version of WinSCP that I need to install to tackle this issue?

@Disha: S3 support is included in the stable version of WinSCP for years now. Make sure you have recent (the latest preferably) version of WinSCP.
