He made a lot of progress toward getting SBCL to be bootstrappable
under CLISP.
+ Perry E. Metzger:
+ He ported SBCL to NetBSD with newer signals, building on the
+ work of Valtteri Vuorikoski. He also provided various cleanups to
+ the C runtime.
+
Gerd Moellman:
He has made many cleanups and improvements, small and large, in
CMU CL (mostly in PCL), which we have gratefully ported to SBCL. Of
He showed how to convince the GNU toolchain to build SBCL in a way
which supports callbacks from C code into SBCL.
+Rudi Schlatte:
+ He ported Paul Foley's simple-streams implementation from cmucl,
+ converted the sbcl manual to Texinfo and wrote a documentation
+ string extractor that keeps function documentation in the manual
+ current.
+
Nikodemus Siivola:
He provided build fixes, in particular to tame the SunOS toolchain,
and has fixed many (stream-related and other) bugs besides.

changes in sbcl-0.8.10 relative to sbcl-0.8.9:
++ * Support for the forthcoming 2.0 version of the NetBSD kernel
++ running on x86 hardware has been added. (thanks to Perry
++ E. Metzger most immediately, and others for their past work)
+ * [placeholder for DX summary]
+ ** user code with &REST lists declared dynamic-extent, under high
+ speed or space and low safety and debug optimization policy.
+ * The manual has been converted to Texinfo format and the debugger
- chapter from the cmucl manual has been added
++ chapter from the cmucl manual has been added.
+ * A facility has been added to extract documentation strings from
+ sbcl and store them as Texinfo-formatted snippets for inclusion in
+ the manual (via Texinfo's @include directive)
* bug fix: compiler emitted division in optimized DEREF. (thanks for
the test case to Dave Roberts)
* bug fix: multidimensional simple arrays loaded from FASLs had fill
pointers. (reported by Sean Ross)
+ * bug fix: PROFILE output is printed nicely even for large numerical
- values. (thanks to Zach Beane)
++ values. (thanks to Zach Beane)
planned incompatible changes in 0.8.x:
* (not done yet, but planned:) When the profiling interface settles
