Here now is a new beta of Hunchentoot which incorporates the bugfixes sent by Travis Cross and which also contains code for AllegroCL, CMUCL, and OpenMCL. The OpenMCL code hasn't been tested at all, the AllegroCL and CMUCL code has been tested only very mildly.

See earlier emails in this thread for instructions. For CMUCL, make sure that you have the newest (0.6.3) version of FLEXI-STREAMS.
