From 1.8:

Name change - is now named MineTogether!

Major new feature - friends list, where you can invite your friends - you just need to share your unique code with your friends, and them with you. After adding each other, you can invite each other to the server you are on, if it is in the public server list.

From 1.8.1:

Fixed bug where people with slow connections could have freezes from time to time. Thank you to Leosky at https://github.com/CreeperHost/CreeperHostGui/issues/7 for the report!

Made it slightly less spammy if repeated net failings for whatever reason (e.g. internet connection off).

From 1.8.2

Add "remove" to chpregen, and also allow you to permit people to join while pregenerating.

Made server.properties handling better - should now be more consistently in the file when starting for the first time.

Added option to instead use "minetogether.properties" in case you are with a server host which rewrites your server.properties on startup.
Fix server localisation.
Make sure it is clear that servers are random, and are not endorsed.
Fix mcmod.info
Now working with "secret" option of API, for extra security.
Remove some debug prints, and now retry if server list fails for whatever reason.
Renamed packages - should no longer crash if an older "CreeperHost" version mod before the name change is also in the instance. Still not a good idea, but I'm not your Mom and can't tell you what to do.
Probably some other things I forgot.
Minor text fixes.

From 1.8.5

Added sorting, made Config more resilient - will just disable mod instead of crashing.
Fixed bug where invite only servers weren't working as I didn't send the hash correctly. I am a dumb.

This version:

Added flag rendering so you know what country each server is in.

Added location sorting - will sort your country to the top, then alphabetically afterwards

Changed how sorting works - no longer needs to refresh every single time sorting is changed

Now has dropdown list for sorting.
