102  ------------------
103  * Fixed generated wrapper for path names with spaces (Windows)
104  * Fixed ticket #58: Inspection of Java objects in Lisp code
105  * Restored functionality of the built-in profiler
106  * Profiler extended with hot-spot counting (as opposed to call counting)
107  * Stack sampling in the profiler moved to scheduler thread to
108    reduce impact on the program execution thread
109  * THE type-checking for the interpreter
110    (for simple-enough type specifications)
111  * Added structure argument type checking in structure slot
112    accessor functions
113  * Make GENSYM thread-safe

142    debugging (Tobias Rittweiler)
143
144    Backtrace functionality been moved from EXT:BACKTRACE-AS-LIST to
145    SYS:BACKTRACE to mark this changes.  The methods SYS:FRAME-TO-STRING
146    and SYS:FRAME-TO-LIST can be used to inspect the new

148  * Various stream input performance optimizations
149  * Fixed breakage when combining Gray streams and the pretty printer
150  * Performance improvements for resolution of non-recursive #=n and #n#

214  * Changes on the lisp based build system for parity with Ant

216  * libabcl.so no longer created; it was solely about installing
217     a SIGINT handler. Libraries should not do that.
218  * boxing of LispObject descendants in JCALL/JCALL-RAW fixed
219  * OpenBSD and NetBSD platform detection
220  * fixed special bindings restores in compiled code for
221     MULTIPLE-VALUE-BIND/LET/LET*/PROGV and function bodies

227     (fixes RESTART-CASE ANSI failures)
228  * fix macroexpansion in the precompiler
229  * Fixnum and Bignum now use a static factory method;
230      constructors are now private -> increases chances of numbers
231      being EQ
232  * Code cleanup in EXPT to fix (EXPT <any-number> <Bignum>)
