MKCL 1.1.0, is now available for general use.
Changes from MKCL 1.1.0 RC4 were:
1) An ABORT restart has been added at the top of each lisp thread to be used as a default target by (abort). Typically invocation of that restart will result in an unwinding of the thread's stack up to its root followed by an orderly final wrap-up of the thread. The only exceptions to this behavior are MKCL standard daemon threads that will then return to their wait point instead of wrapping up.
2) A problem has been identified in the RC4 update of the SLIME bundled version with respect to the transmission of non-ascii characters between Emacs and the Swank server. The problem has been fixed in this version.
On to MKCL 1.2.0, which will include new features and new platforms.
Enjoy,
