    1.0:
        release, will be tagged as sbcl_1_0
What's changed since then? I'll list my own favorites here (in reverse order of appearance).
- Hash-tables with synchronization support over multiple accesses.
 - Compare and swap support on several kinds of places.
 - Support for user-defined subclasses of SPECIALIZER.
 - Code coverage support.
 - XREF support.
 - Support for user-defined subclasses of SEQUENCE.
 
Not counting optimizations or bugfixes here at all. If I was, I'd make a big deal about how SBCL threads are finally starting to mature. Or list Big-Oh / order of magnitude optimizations. Or rant about the old chestnut, interrupt-safety...
Maybe it's time to start thinking about 1.1...
