# Vcsn 2.8 (2018-05-08)
## New Features
### vcsn diagnose: check that Vcsn is properly installed
This tool runs a few commands to check that Vcsn works properly. It
generates diagnostics that help the Vcsn team understand problems on the
user side.
## Bug Fixes
### Spontaneous transitions in literal automata
In literal automata, transitions without explicit label were accepted but
misinterpreted. For instance in this automaton in Daut:
context = lao, q
$ 0 <2>
0 1 <3>
1 $ <4>
the pre- and post-transitions have no label, but are weighted (by 2 and 4).
The inner transition between states 0 and 1 should be labeled with `\e` (and
be weighted by 3). Unfortunately the user was expected to make the `\e`
explicit:
context = lao, q
$ 0 <2>
0 1 <3>\e
1 $ <4>
otherwise unexpected results would be yielded (for instance the first
automaton was considered proper).
Now, missing labels are interpreted as the empty word, and both
specifications above denote the same automaton.
