+  * An alpha-quality port to the parisc architecture running Linux,
+    based on the old CMUCL backend, has been made.  This, even more so
+    than the other backends, should be considered still a work in
+    progress; known problems include that the Linux kernel in 64-bit
+    mode does not propagate the correct sigcontext structure to
+    userspace, and consequently SBCL on a parisc64 kernel will not
+    work yet.
   * fixed bug 189: The compiler now respects NOTINLINE declarations for
     functions declared in FLET and LABELS. (I.e. "LET conversion" is
