What's happened to m4b?

[skypilotpete]

Is there a reason that m4b no longer appears in the available codecs? I know that all you have to do is rename m4a files, but that is one extra step that never used to be necessary. I've got all the files in the folder
C:\Program Files (x86)\Illustrate\dBpoweramp\encoder\m4b\ but when I try to convert using dbpoweramp or dbpoweramp batch converter, the m4b option is no longer available.
I run Windows 7 64, dBpoweramp Reference 14.2

It shall be added back into the next FDK AAC Encoder (which is in beta)
