Zeng Zi has noted two things: the EDB Romanization is no longer a choice for looking up information on EDB's website. Since EDB was originally named so as it was recognized by it as the only standard Romanization, Zeng Zi calls it the "ex-EDB Romanization".
Also, [tut˥] (嘟) has become a verb in daily Cantonese usage, as he points out. This means that Chao's Cantonese Romanization does not officially cater to this sound, but using his, and my, interpretation, the sound could be written as <twut>.
