 changes in sbcl-0.7.5 relative to sbcl-0.7.4:

     cross-compilation host; also, more progress has been made toward
     bootstrapping under CLISP.
-  * bug 140 fixed: redefinition of classes with different supertypes
-    is now reflected in the type hierarchy. (thanks to Pierre Mai)
-  * bug 158 fixed: the compiler can now deal with integer loop
+  * SBCL now runs on the Tru64 (aka OSF/1) operating system on the

+  * bug 158 fixed: The compiler can now deal with integer loop
     increments different from 1; fixing this turned out also to fix
     bug 164.
   * bug 169 fixed: no more bogus warnings about using lexical bindings

+  * bug 175 fixed: CHANGE-CLASS is now more ANSI-conforming,

   * bug 179 fixed: DIRECTORY can now deal with filenames with pattern
     characters in them.
+  * bug 180 fixed: Method combination specifications no longer ignore

   * minor incompatible change: The --noprogrammer option is deprecated
-    in favor of the new name --disable-debugger option, which takes
-    effect at a slightly different time at startup (so that e.g.
-    handling of errors in --sysinit and --userinit files will be affected

+changes in sbcl-0.7.6 relative to sbcl-0.7.5:
+  * bug fix: Floating point exceptions are treated much more
+    consistently on the x86/Linux and PPC/Linux platforms.
+  * Array initialization with :INITIAL-ELEMENT is now much faster for
+    cases when the compiler cannot open code the array creation, but
+    does know what the UPGRADED-ARRAY-ELEMENT-TYPE will be. General
+    array accesses have also seen a speed increase.
+  * bug fix: LOAD :IF-DOES-NOT-EXIST NIL now works when file type is
+    specified. (This was at the root of some bad interactions between
+    SBCL and ILISP: thanks to Gregory Wright for diagnosing this and
+    reporting the bug.)
+  * bug fix: Internal error arguments for undefined functions are now
+    computed correctly on the PPC/Linux platform.
+  * bug fix: Bad &REST syntax is now checked correctly. (thanks to 
+    Raymond Toy's patch for CMU CL)
+  * Support for the Solaris 9 operating environment has been included
+    (thanks to Daniel Merritt)
+  * A very ugly but hopefully complete draft of the missing FFI chapter
+    of the manual has been created by reformatting the corresponding
+    CMU CL manual chapter into (currently very ugly and incoherent)
+    DocBook and bringing it up to date for SBCL behavior. Thus, the
+    manual is now essentially complete, at least by my extreme
+    once-and-only-once standards, whereby it's acceptable to refer to
+    the doc strings of SB-EXT functions as the primary documentation.
+  * The fasl file version number has changed again, due to cleanup of
+    (user-invisible) bitrotted stuff. (E.g. *!INITIAL-FDEFN-OBJECTS*
+    is no longer a static symbol.)
+
+changes in sbcl-0.7.7 relative to sbcl-0.7.6:
+  * fixed bug 189: The compiler now respects NOTINLINE declarations for
+    functions declared in FLET and LABELS. (I.e. "LET conversion" is
+    suppressed.) Also now that the compiler is looking at declarations
+    in the environment, it checks optimization declarations as well,
+    and suppresses inlining when (> DEBUG SPEED).
+  * More fixes have been made to treatment of floating point exception
+    treatment and other Unix signals.  In particular, floating point
+    exceptions no longer cause Bus errors on the SPARC/Linux platform.
+  * The detection and handling of control stack exhaustion (infinite
+    or very deeply nested recursion) has changed.  Stack exhaustion
+    detection is now done by write-protecting pages at the OS level
+    and applies at all optimization settings; when found, a
+    SB-KERNEL:CONTROL-STACK_EXHAUSTED condition (subclass of
+    STORAGE-CONDITION) is signalled, so stack exhaustion can no longer
+    be caught using IGNORE-ERRORS
 
 planned incompatible changes in 0.7.x:
