================
Backwards incompatible changes
------------------------------
- A value pseudonymized by ``text()`` no longer contains full stops, they are
converted to spaces. Thus the pseudonymized values may change since version
1.1. (``string()`` now has the former behavior of ``text()``, see below.)
- ``email()`` now returns its result in all lower case.
Features
--------
- Add ``string()`` pseudonymizer returning a string containing numbers, digits
and full stops. (This is what ``text()`` formerly did.)
Bug fixes
---------
- Fix all pseudonymizers: if called with a value which evaluates to `False` the
value is returned. But ``integer()`` still pseudonymizes `0`.
- Fix ``email()`` so it does not break on an input value which does not contain
an `` symbol.
