+Functional changes to MPS code:
+
+<http://www.ravenbrook.com/project/mps/issue/job001548/>
+Defect discovered:
+  - an assert could, rarely, be incorrectly triggered when a pool 
+    of mps_class_amc is in a constrained memory condition.
+Fixed: in this rare case, calculate a certain value correctly, 
+    such that the assert which checks it is not incorrectly 
+    triggered.
+
+<http://www.ravenbrook.com/project/mps/issue/job001658/>
+Defect discovered:
+  - finalization messages could suffer an unnecessary delay, of 
+    several full collections (in the worst case), if there were 
+    more than 1024 finalization-registered objects;
+Fixed: the number of finalization-registered objects should 
+    no longer cause such a delay, so more finalization messages 
+    are likely to be produced by a single collection.
+
+<http://www.ravenbrook.com/project/mps/issue/job001147/>
+  - on Mac OS X (PowerPC and Intel), MPS now has memory-protection 
+    code, so collections are much faster.
+
+<http://www.ravenbrook.com/project/mps/issue/job001619/>
+  - on Mac OS X (Intel), MPS now has stack-scanner code, so the 
+    stack may be declared an ambiguous root.  (Note: there was 
+    already a stack-scanner for Mac OS X PowerPC).
+
+<http://www.ravenbrook.com/project/mps/issue/job001622/>
+  - on Mac OS X (PowerPC and Intel), MPS now has locking code, so 
+    multiple client threads may use the MPS.  (But note: the thread 
+    module has not been implemented for Mac OS X, so threads may 
+    not yet have their stacks as roots, I think.  See:
+    <http://www.ravenbrook.com/project/mps/issue/job001621/>).
+    
+<http://www.ravenbrook.com/project/mps/issue/job001556/>
+Defect discovered:
+  - a macro used only in asserts was incorrect; this could have made 
+    some checks ineffective.
+Fixed: corrected the macro.
+
+Other changes:
+
+<http://www.ravenbrook.com/project/mps/issue/job001624/>
+  - now builds on FreeBSD 5.5.
+
+<http://www.ravenbrook.com/project/mps/issue/job001637/>
+  - now builds on Linux.
+
+<http://www.ravenbrook.com/project/mps/issue/job001617/>
+  - on Mac OS X (Intel) default "all" build works (fix broken 
+    compile of amsss stress test).
