 * ==================== TOOL CHANGES ====================
 
 * Memcheck:
 
-  - Default value for --keep-stacktraces has been changed to alloc-and-free.
-    This has a small cost in memory (one word per malloc-ed block) but
-    allows memcheck to e.g. give the 3 stacktraces of a dangling reference:
-    Where the block was allocated, where it was freed, and where it is
-    acccessed after free.

+  - The default value for --partial-loads-ok has been changed from "no" to 
+    "yes", so as to avoid false positive errors resulting from some kinds
+    of vectorised loops.

+* The default values for some command line options have been changed to
+  be more suitable for common use cases:
 
   - A new monitor command 'xb <addr> <len>' shows the validity bits of
     <len> bytes at <addr>.  The monitor command 'xb' is easier to use

+* The default value for the --smc-check option has been changed from
+  "stack" to "all-non-file" on targets that provide automatic D-I
