+ include fixes for various compiler bugs, the implementation of
+ CL:DEFINE-SYMBOL-MACRO, and a generalization of the type system's
+ handling of the CONS type to allow ANSI-style (CONS FOO BAR) types.
+
+Alexey Dejneka:
+ He fixed many, many bugs on various themes, and has done a
+ tremendous amount of work on the compiler in particular, fixing
+ bugs and refactoring.
+
+Paul Dietz:
+ He is in the process of writing a comprehensive test suite
+ for the requirements of the ANSI Common Lisp standard. Already, at
+ the halfway stage, it has caught hundreds of bugs in SBCL, and
+ provided simple test cases for them. His random crash tester has
+ caught an old deep problem in the implementation of the stack
+ analysis phase in the compiler.
+
+Brian Downing:
+ He fixed the linker problems for building SBCL on Mac OS X.
+
+Miles Egan:
+ He creates binary packages of SBCL releases for Red Hat and other
+ (which?) platforms
+
+Nathan Froyd:
+ He has fixed various bugs, and also done a lot of internal
+ cleanup, not visible at the user level but important for
+ maintenance. (E.g. converting the PCL code to use LOOP instead
+ of the old weird pre-ANSI ITERATE macro so that the code can be
+ read without being an expert in ancient languages and so that we
+ can delete a thousand lines of implement-ITERATE macrology from
+ the codebase.)
+
+Matthias Hoelzl:
+ He reported and fixed COMPILE's misbehavior on macros.
+
+Espen S Johnsen:
+ He provided an ANSI-compliant version of CHANGE-CLASS for PCL.
+
+Frederik Kuivinen:
+ He showed how to implement the DEBUG-RETURN functionality.
+
+Arthur Lemmens:
+ He found and fixed a number of SBCL bugs while partially porting
+ SBCL to bootstrap under Lispworks for Windows
