Applescript support is improved, not removed, but incompatibly. https://iterm2.com/applescript.html
Applescript is supported, just in a more consistent way now.
This is the new syntax: https://iterm2.com/applescript.html
Edit: I'm not the developer! I'm just a fan.
Awesome and thanks for the great work!!
What you are looking for sounds a lot like TMUX + Bash (scripted tmux setup).
Then you can run that inside of iTerm.
Tmux supports tabs and dynamic splits nicely via ncurses.
Also check out tmux ressurect [1] for saving tmux session persistence.

FWIW, I've been running the dev builds for ages now (currently on 2.9.2015111), and it wasn't a big deal to update my (few) scripts. The new AppleScript dictionary is definitely a bit better, and simplified my scripts.

Hey - I wrote one for iTerm called iTermocil:
https://github.com/TomAnthony/itermocil
Yiu can use teamocil style files to configures panes/tabs and starting commands for each pane.
Let me know how you find it! :)
Can anyone recommend another macro tool that can set up a bunch of processes running in tabs?
