Vcsn 2.1 (October 11th, 2015)

About 10,000 hours (on the calendar, not of work!) after its first public release, the Vcsn team is very happy to announce the release of Vcsn 2.1!

It is quite hard to cherry-pick a few new features that have been added in Vcsn 2.1, as shown by the 4k+ lines of NEWS since 2.0. However, here are a few headlines:

Many pages of documentation and examples have been written (see http://www.lrde.epita.fr/dload/vcsn/2.1/notebooks).
Now http://vcsn-sandbox.lrde.epita.fr/ provides a live demo.
Transducers are much better supported, with improved syntax and several algorithms (e.g., letterize, synchronize, partial_identity, is_functional, etc.)
Expressions now offer several sets of identities specifying how they should be normalized. More generally, input/output of expressions have been improved to match most users' expectations. New operators are accepted: & for conjunction, : for shuffle, &: for infiltration, {c} (postfix) for complement, and <+ for deterministic choice.
When entering an automaton (e.g., with %%automaton in IPython) user state names are preserved.
Of course, many bugs were fixed, many algorithms were sped up, and internal details have been cleaned up.
As Easter eggs, many features have also been added, but not advertised, until we are sure of how we want them to look like.

Graphviz: The display of automata is made using AT&T Graphviz library. (On Ubuntu/Debian, install the following package: graphviz)
Boost: Boost (version 1.49 or later) provides free peer-reviewed portable C++ source libraries (at least the Boost.Python and Boost.Regex components, and probably others).
Flex: The Flex scanner generater, 2.5.37 or better.
