Upgrade Changelog?

Since purchasing the theme about two weeks ago, I’ve already seen one or two upgrades come up (currently at v1.0.2, I think). Two questions:

1) Can the home page of this theme on your site be updated to show the current version? It still shows v1.0.0.

2) When the theme is upgraded, can a changelog be provided to show what was done? I’ve noticed a few settings seem to go back to their defaults. It would be handy to know what I need to look at to make sure the settings are the way I want them if changed from the defaults.
