I think they really hit the mark with this version. Stable, OSX native and waaaay faster!

The new features are great. I just wish that there were more modules to use with the actions functionality out of the box.

The Quark integration is great, the InDesign integration is not as strong but is still a leap in the right direction.

They are still on top of it for Digital RAW formats.
It may not detect parent child relationships with files but you can now create Master/Slave files or "variations". This goes well with the new split panel thumbnail screen, where the lower split screen displays the relation assets to the one you have selected in the primary screen.

I Haven't done much with the scheduler yet, so I really can't comment too much on it.

Web Publisher Pro and Internet Client pro have a completely different feel. Same ideas just much faster. AJAX is behind the new sites so it requires a little more know how to edit. But fortunately not as much editing is need since record view sets now work with the client and the web, all configured just from the client. This goes for saved queries, collections and category view sets.

The only downer is that you can't set independent action to convert each asset the same way you did in 3.0 when downloading.

Using the Cumulus 7 Java Classes to update the Helios Companion yields a huge jump in performance. The JC handles the loads much better as well as cataloging and updating files much faster.

All in all its the best release Canto has had yet!!

Two Thumbs up!
