https://github.com/anthropics/claude-code/issues/2337 says this was solved, but does not link to any docs.

Update: I found this in the changelogs:

v1.0.33
Improved logging functionality with session ID support
Added undo functionality (Ctrl+Z and vim 'u' command)
Improvements to plan mode

But pressing ctrl-z still puts the current process into background on my terminal (kitty, macOS). Is this a terminal config issue?
