+             been replaced with with improved implementations which conform to writef. In some,
+             rare cases, this will break code. Please see the documentation for std.string.format
+             and std.string.sformat for details.))
+        $(LI std.range.hasSlicing has been made stricter in an effort to make it more reliable.
+             opSlice for infinite ranges must now return the result of std.range.take, and any
+             range with slicing which supports $(D $) must now support it with the same semantics
+             as arrays (including supporting subtraction for finite ranges).)
+        $(LI std.range.isRandomAccessRange now requires hasLength for finite ranges, as it makes no
+             sense for such ranges not to define length and many random-access algorithms rely
+             on length.)
         $(LI std.digest: Added new package for digests. This replaces std.md5 and the internal crc32
              implementation.)
         $(LI std.digest.sha: Added SHA1 digest implementation, including a fast SSSE3 version.)
