+Changes in 2.4:
+* Read TOC entries from the CD. The default uses cdrdao. The program mkcue is
+ also optional.
+* Possibility to use CDDBCHOICE1,CDDBCHOICE2 (i.e., 1,3) to get a diff of two
+ parsed CDDB entries.
+* Added SHOWCDDBFIELDS to define wether to show the YEAR and GENRE fields from
+ the CDDB output.
+* Added the possibility of embeding a cuesheet on a singletrack flac file. A
+ single BACKUP flag is most likely needed to use all the needed flags:
+ "abcde -1 -o flac -a default,cue"
+* Added the possibility of using a singletrack flac file with an embeded
+ cuesheet as a source to extract tracks from (use -X to specify an external
+ CUE2DISCID implementation; check under examples in the distributed source
+ code or package).
+* Added replaygain for Ogg/Vorbis and Ogg/FLAC.
+* Added M4A encoding.
+* Uses the default found $CDROMREADER instead of forcing cdparanoia when
+ cdda2wav is installed.
+* BATCH mode has been split into two options: BATCHNORM and NOGAP.
+* Added -U option for non-UNICODE (non UTF-8) tag encoding.
+* Added -z for debug.
+* Added -f to force the removal of left files.
+* CUE support has changed from a flag (-M) to an action (cue).
+
+Changes in 2.3:
+* Support for mkcue, to create a CUE sheet of the CD structure. It can be used
+ with "-1" to create a backup, so that later the original CD can be recreated.
+* New -o <output(1)>:<options(1)>,... way of passing specific options to an
+ output. Now we can pass specific options without having to modify a config
+ file. This feature was already present in the last versions of the 2.2 cycle.
+* Unix PIPEs, as a second way to encode files with a low disc space.
+* Option to erase the "encoded" entries from the status file. Allows one to
+ encode the wav files (in case they were not erased) into another format. This
+ is needed until status information is stored for each format.
+* The "ogg" output mode will be substituted for "vorbis" in the near future.
+ This release adds a compatibility layer so that both entries work.
+* The FLAC encoder forces the files to be overwritten, in case they previously
+ exists. This avoids a half-through abcde run to continue without errors in
+ case it was cancelled during the FLAC encoding.
+* Added a post_read() function so that we can do things with the CD before we
+ eject it.
+
+Changes in 2.2:
+
+* Support for MPP/MP+(Musepack) format. It can be downloaded from
