Tag releases properly, and update changelog.
If you visit https://bitbucket.org/cleonello/jqplot/downloads/ there are a number of recent downloads listed that have not had a tag made for them.
This makes it very hard to figure out what has changed between revisions, or which particular revision a release package was made from.
Also, the release notes in changes.txt have not been being updated.
Please updated the changelog and create tags for all releases since 1.0.0b2 (the latest tag to exist) and continue to update in this manner for future releases.
Thank you for a great bit of software!
