Every Japanese IME converts a reading to Katakana on demand; strans made
the user switch to the Katakana mode and type again. Space now adds
the reading in Katakana after the dictionary candidates, so a loanword
the dictionary lacks converts with one Space and Enter, and 漢字 users
still get 漢字 first.
0 committed the reading only while candidates showed; without them it
typed a 0 as well. It now commits any Japanese reading, the counterpart
of 1-9 picking candidates, as the README always said.
