I host a Unix-based Minecraft server whose population is those people who like to be on the most up2date version of Minecraft as soon as it's released. I have a WebUI that updates the server jar based on the old URI scheme:
http://s3.amazonaws.com/MinecraftDownload/launcher/minecraft_server.jar

This allowed for easy, 1 click updates without me having to futz around on the filesystem. It was also easily automated using a cron script.

With the new URI structure, this is no longer feasible, as now the directory changes and so I have to go in and manually change my script. It's also no longer feasible to automate updates.

Please consider re-creating a symlink on AWS to the latest MC jar file. It would make my life (and other server admins lives) a little easier
