I don't care, as long as you release it rather soon. :)
Especially the -show:left should be included in 1.7.3.3, though.
May I add wishes?
* inclusion of john.pot (the cleartext half) in wordlist mode (round 2
in autocracking mode) as if it was part of the specified wordlist.
(try already cracked passwords from previous runs, useful on other
hash types.) or is that done already?
* a defined interface for salted raw-MD5 hashes, where the salt-pass-
hash combination can be adjusted in john.conf (as an external mode).
Examples: MD5($pass.$salt), MD5(MD5($pass).$salt)
I had someting else in mind, but forgot.
