As of 0.9.2:

* base64, sha1, ntdes, clearlist operators
* MSCHAPv2 / MPPE support
* Finish tools/radclient - currently it handles only the transaction, 
  nothing else: it doesn't even check the response digest
* PAP, CHAP, MSCHAPv2 generator for use with tools/radclient
* DBM module with read- *and* write support (for building session DBs)
* PAM module
* Enhance logging module a bit: write to different files based on an attribute 
  sent to it (to be able to write to a different file for each NAS, realm, 
  phone nr. or whatever).
* Proxying module
* DNS resolver module that returns strs for ips and vice versa.
* MySQL module
* Duplicate module that keeps a two minute cache of request signatures
  (as specified in a str parameter) to detect retransmits and flag them;
  useful to lessen the impact of retransmits on underlying DBs; also
  useful for on-line single-server accounting duplicate stripping.
* Clean up buildtree()
* Better documentation
* More useful sample configuration/behaviour combos
