Polls add-on has been recently updated to the version 1.3.4. There are just couple of minor functionality changes:

- Voting graph now will be sorted by the number of votes, highest on top (that brings more look & feel to Polls results);
- the Multiple votes polls percents graph will be based on the amount of voters, not votes (which would bring more perceptive results).

File to update is addon_polls.php.
