I would probably make this into one entry, like so:
*** IELM now remembers input history between sessions.
The new user option 'ielm-history-file-name' is the name of the file
where IELM input history will be saved. Customize it to nil to revert
to the old behavior of not remembering input history between sessions.

The tag here should be "Disable input history" or something like that.

This should read
(defvar ielm--exit nil
or the below docstring will instead be its value.

There are some complications here:
You can get more than one IELM buffer using
M-x ielm RET
M-x rename-buffer RET foo RET
M-x ielm RET
What happens if there is more than one IELM buffer? It will save only
the history from the last one, or something like that?
Perhaps the kill-emacs-hook should look for all buffers that are using
`ielm-mode' and save the history from all of them?
