The 0.17.2 release only had the native code compiled in 32 bit. While
that matches our current release process, which considers the 64 bit
optional, some users would like to have the 64 bit libraries also.
Since the 0.17.2 release had already been voted on, I rolled a new
release, which I called 0.17.2.1 and that has identical source code to
0.17.2. Should we release it?
