626 @cindex MULE merged XEmacs appears
627 Soon after 19.13 was released, work began in earnest on the MULE
628 internationalization code and the source tree was divided into two
629 development paths. The MULE version was initially called 19.20, but was
630 soon renamed to 20.0. In 1996 Martin Buchholz of Sun Microsystems took
631 over the care and feeding of it and worked on it in parallel with the
632 19.14 development that was occurring at the same time. After much work
633 by Martin, it was decided to release 20.0 ahead of 19.15 in February
634 1997. The source tree remained divided until 20.1 when the version 19
635 source was finally retired.
