PR.com has just announced several changes to their press release distribution options. Here’s a run-down of new features available through their online press release distribution options (btw, this is my personal favorite in press release distribution sites):

Yahoo! News Distribution - Press releases distributed through PR.com will now be distributed to Yahoo! News with an upgraded press release visibility option.

File Attachments - You can now attach a variety of files, from images to Word documents, to press releases distributed on PR.com.

PDF Press Release Version - PR.com now automatically creates a .pdf version of submitted press releases, which can be indexed by search engines.

Industry and Regional Distribution Channels - Now, when distributing a press release through PR.com, you can enhance your distribution by including industry- or regional-focused distribution, to help browsers find the release in relevant searches.

Social Bookmarking - Social bookmarking options for sites such as Digg and Del.icio.us have been added to PR.com press releases.
