+changes in sbcl-1.0.28 relative to 1.0.27:
+  * bug fix: timers could go off in the wrong order, be delayed indefinitely
+    (thanks to Ole Arndt for the patch)
+  * bug fix: RESTART-FRAME and RETURN-FROM-FRAME stack corruption

+changes in sbcl-1.0.27 relative to 1.0.26:
+  * new port: support added for x86-64 OpenBSD. (thanks to Josh Elsasser)
+  * new port: support added for x86-64 Solaris. (thanks to Alex Viskovatoff)
+  * improvement: the system either recovers from stack exhaustion or dies
+    properly as opposed to leaving the user uncertain of whether the handler
+    trampled on some random memory next to the stack or having to rely on
+    --lose-on-corruption (which is still a good idea to use in production
+    because stack exhaustion can happen in signal handlers which will likely
+    lead to hangs.)
+  * bug fix: fix gc related interrupt handling bug on ppc (regression from
+    1.0.25.37, reported by Harald Hanche-Olsen)
+  * bug fix: work around signal delivery bug in darwin (regression from
+    1.0.25.44, reported by Sidney Markowitz)
+  * bug fix: fix ERROR leaking memory (reported by David Thompson)

+  * incompatible change: an interruption (be it a function passed to

+    WITHOUT-INTERRUPTS to avoid nesting of interruptions and
+    potentially running out of stack. Keep in mind that in the absence
+    of WITHOUT-INTERRUPTS some potentially blocking operation such as
+    acquiring a lock can enable interrupts.
+  * incompatible change: GC-OFF and GC-ON are removed, as they were
     always unsafe. Use WITHOUT-GCING instead.

+  * enhancement: detect binding stack exhaustion
+  * enhancement: detect alien stack exhaustion on x86/x86-64
+  * improvement: generally more stable and reliable interrupt handling
+  * improvement: there is a per thread interruption queue,

+  * improvement: a repeating timer reschedules itself when the it has

   * optimization: slightly faster gc on multithreaded builds

   * bug fix: real-time signals are not used anymore, so no more
