+  <li> New: There is now a function Utilities::to_string that works like
+  int_to_string, but is more safe for long integers, negative integers, and
+  also handles floating point numbers. The implementation of int_to_string
+  was changed to simply call to_string. int_to_string is kept for
+  compatibility, but should only be used for unsigned integers.

   <li> New: The WorkStream class's design and implementation are now much
   better documented in the form of a @ref workstream_paper "preprint".
