(reported by Josh Elsasser) + +changes in sbcl-1.0.22 relative to 1.0.21: + * minor incompatible change: LOAD-SHARED-OBJECT no longer by default looks + for the shared object in the current directory, but passes the native + namestring of the designated pathname to the operation system's shared + object loading function as-it. + * minor incompatible change: --disable-debugger toplevel option now takes + effect before processing of initialization files and --eval or --load + options. + * new feature: new commandline argument: --script, which supports + shebang lines. See documentation for details. (based on work by + Kevin Reid) + * new feature: SAVE-LISP-AND-DIE can save current values of + --dynamic-space-size and --control-stack-size in the executable core, + causing it to skip normal runtime option processing. See documentation + for details. (thanks to Zach Beane) + * enhancement: inoccous calls to EVAL or generic functions dispatching + on subclasses of eg. STREAM no longer cause compiler notes to appear. + * enhancement: the system no longer resignals errors from --load and + --eval toplevel arguments as SIMPLE-ERRORS, which caused restarts + associated with the original error to be lost. (thanks to Ariel + Badichi) + * enhancement: :DONT-SAVE keyword argument has been added to + LOAD-SHARED-OBJECT for controlling interaction with + SAVE-LISP-AND-DIE, and UNLOAD-SHARED-OBJECT can be used to undo + the effects of an earlier LOAD-SHARED-OBJECT call. + * bug fix: ADJUST-ARRAY on multidimensional arrays used bogusly give + them a fill pointer unless :DISPLACED-TO or :INITIAL-CONTENTS were + provided. (reported by Cedric St-Jean) + * bug fix: circularity handling in the reader did not treat raw + structure slots correctly. (reported by Cedric St-Jean) + * bug fix: SERVE-EVENT occasionally signaled an error about bogus + file descriptors when there were none. + * bug fix: DEFINE-COMPILER-MACRO support of destructuring lambda-lists + was broken.
