--------------------------------------------------

- Change internal trie representation thanks to that performance
of common operation is 1.5 - 2.5 times faster. Details are
presented in https://github.com/WojciechMula/pyahocorasick/pull/107
Warning: this change breaks compatibility of pickle and ``save()``
format, this won't be possible to load files created in the
previous version.

--------------------------------------------------

- Add alternative pickling mechanism ``save()``/``load``, which
requires less memory than the standard pickle solution (issue 102)

--------------------------------------------------

- Add methods ``remove_word()``/``pop()`` (issue 79)

--------------------------------------------------

- Fix manifest file

--------------------------------------------------

- Fix pickling of large automatons (issue 50);
The fix wouldn't be possible without great help and
patience of all people involved:

* **Emil Stenström** (EmilStenstrom)
* **David Woakes** (woakesd)
* **Dobatymo**
* **Philippe Ombredanne** (pombredanne)

The fix wouldn't also be possible without **Daniel Lemire** (lemire),
who gave me access to decent machines and I was able to test fixes
on large data.

--------------------------------------------------

- Add support for tuples of ints to ``iter()`` (by **Frankie Robertson**)
