We've released #PuTTY version 0.83.
This release is mostly full of bug fixes following up the new development in 0.82. Most significantly, 'psftp -b' was completely broken, and now works again. Also various assertion failures, crashes and hangs. On the Unix side, we've fixed an intermittent bug making the keys on the small keypad above the arrows (Home, End, Ins, Del etc) not work in the terminal.
We've also extended our #quantumsafe cryptography support, by supporting #MLKEM as a key exchange option, in addition to NTRU Prime which we already had.
