 Since 1.1 BETA:

+---------------
+
+- I/O clustering is implemented for all block devices.  This should
+  substantially improve the performance of disk drives which don't
+  have write-behind caches, especially on IDE drives.  (dyson/davidg)
+
+- Allow mbufs to point to other ``external'' objects than just
+  clusters, and add in performance enhancements for NFS from Yuval
+  Yarom.  (davidg)
+
+- Yet more VM system improvements.  (dyson/davidg)
+  o 4-MB systems should now spend substantially less time in the VM
+    system.
+  o General cleanup and some portability fixes.
+  o A new system process is now responsible for keeping page
+    statistics, rather than making the pagedaemon do it, which was
+    getting impractical.  Performance is improved on small-memory
+    machines.
+  o Process resource usage counters are now properly updated for
+    faults and swaps.
+
+- Fixed bugs in truncating mapped files.  (dyson/davidg)
+
+- A new version of the interrupt-handler glue code has been added, which
+  is faster and architecturally cleaner than the previous version.  The
+  beginnings of better profiling support have also been added.  (bde/davidg)

 - Improved lpt driver, should no longer lock up when lprm is done on
   an active job.  Fixed up the probe routine so that it works on most
   if not all printers now. (csgr/rgrimes)
