- Added more output to zipdir and a -q option to turn it off. - Added -u option to zipdir to only recompress those files in a zip that have changed. - Added -d and -f options to zipdir. -d forces deflate compression, and -f forces a write of the zip, even if it's newer than all the files it contains. - Added support for bzip2 and LZMA compression to zipdir.
