== Changes since version 1.4 ==

Vaucanson 1.4.1 is a maintenance release that fixes some bugs, and introduce a few simple new features.

* New TAF-Kit commands: <tt>coquotient</tt>, <tt>alphabet</tt>, <tt>partial-erase</tt>, <tt>gui</tt>.

* Bug fixes:
** never create 0-labeled transitions in <tt>proper</tt>
** fix support of transitions that are linear combinations of pairs in FMP transducers
