0.4.7 (to be announced) "infinite rollback"
-------------------------------------------
+The new ao writer, support for ssh RSA keys and a couple of other
+enhancements.
+
- Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
platforms through the libao audio library.
- Support for RSA keys generated with ssh-keygen.
- The autogen script detects the number of processors and
runs a parallel make if possible.
- Major cleanup of the crypto API.
+ - Documentation updates.
