What's excited you about Zandronum 3, currently I know very little.

Would it be possible to compile a list of the new things that can be done with Zandronum 3. I know about map cards, but do not know of any other features/big changes available.

This shouldn't be in the tutorial collection.

And to answer your question, I don't know of any new features but what I would like to see implemented is when in roboenza mode, the player gets to keep their skin when infected instead of their skin turning into a default zombie.

It would take a long while to compile a full list of changes and features Zandronum 3.0 brings to the table. Things previously just out of reach such as pointers for various action functions, pointer manipulation flags, on-the-fly scale changing, A_Warp, SetCVarString, GetCVarString, GetUserCVar, just to name a few.

If you really want to dig and find every little detail you can look through the Zandronum forum (http://zandronum.com/forum/viewforum.php?f=55) and the ZDoom wiki's version history through 2.7.1 (https://zdoom.org/wiki/ZDoom_version_history#2.7.1). Note that 2.7.1 does not contain every single change made to the engine. Zandronum is actually based on GZDoom 1.8.6, which contains "over a year's worth of changes since ZDoom 2.7.1" according to this thread: http://zandronum.com/forum/viewtopic.php?f=55&t=6334

As can be noted, Zandronum 3.0 has been in development for a long while, well over two years. This time has allowed many of Zandronum 3.0's features to be added and tuned to fit the needs of the community as a whole.
