CMUCL 19d was released recently. Here's the announcement. I don't use CMUCL any more, and sometimes I get the impression that it isn't under very active development, but the announcement lists a huge number of enhancements and fixes. A few things that I noticed:
- New float type DOUBLE-DOUBLE-FLOAT. I confess I was among the many who made a bad "toil and trouble" joke while Raymond Toy was working on this.
- TRACE supports FLET/LABELS functions
- Full-featured weak hash tables
I also learned that there's a CMUCL Trac bug tracker.
