Release Notes: There is a bugfix to comply with POSIX regular expressions. This appears to be relevant to Red Hat 8.0 systems. Also of note is that the tarball now decompresses everything into a cdrx-(version) directory, rather than dumping everything into the current directory.
Release Notes: A major bug in burn_iso_cd() was fixed. This bug resulted in no ISO images being shown when listing the contents of the directory.
