This afternoon we’re pushing another free auto-update to P4. Everyone on a capable web-host (about 96% of you) should see ProPhoto auto-update itself within 24 hours. This auto-update has some pretty cool new stuff, and I’ll be blogging more in the coming days about some of the details of the new features. Here’s a couple teasers:

Music for slideshows is back…

…and better than ever. We removed music support completely when we dropped all flash in our P4 upgrade, but now we’ve added back support for music in slideshows with a non-flash, HTML5 music player that also works on iPads and iPhones. ProPhoto will also automatically reconnect all of your old P3 MP3 files to your imported P4 galleries. More details in a future blog post.

Basic Pinterest support

This is only the beginning of our plans for Pinterest integration in the weeks and months to come, but we’ve started by adding simple, built-in Pinterest “Follow” and “Pin site image” options into the “Call to Action” option area. Check it out and let us know what you think.

Facebook “Like” button improvements

Improved Facebook integration was the most requested new feature in our recent poll, so we’ve already gotten started making improvements. We’ll have lots of details in future blog posts, but the basics of this update include:

New free starter design: Sunny California

We teamed up with Matt from LaLune Creative to add a new, free starter design, called Sunny California.

The new design looks great, and makes use of the new built-in Pinterest Call-to-action functionality. One of the reasons we added this new starter design was to replace “Late August” as the default starter for new users. Late August is great, and still a free, included starter design, but it’s not the easiest to edit and customize, so we thought it would be a win for usability to start out with a more straightforward starter design.

The gory details:

For the nerdy or incredibly inquisitive out there, here’s the standard run-down of just about everything that was changed since the last auto-update we pushed:
