+
 * Rewrote the dummy_property_map.
     This looks a lot nicer if the key and value type are explicitly given.
     The general behavior is a) to return an arbitrary value and b) ignore any
     writes.
+
+* Moved dynamic_property_map.hpp into the property_map library.
+    Made a couple of small changes - mostly cosmetic. Removed backwards
+    compatible support for GCC 2.95 (had to do with proper scoping).
+
+    The dynamic property map is kind of a strange thing, because it requires
+    that any maps it contains have to be models of both Readable and Writable
+    property maps - if it's read only, we can't instantiate the adaptor class.
+    As such, many of the property maps that wouldn't normally support put or
+    get functions, actually have them - even if they don't do anything.
