Version 4.0 supports 64 bit macOS

I am excited to announce version 4.0 is coming with 64 bit support. I am sorry this has taken so long. I’ve neglected AudiobookWizard and allow long time users to suffer from issues arising from macOS changes. But no more! Version 4.0 will support 64 bit and fix many ongoing issues. Please be patient as I expect to release the new version within a month or so.
