A new feature: Sitemaps for your store was implemented.
What strikes me, is that they only mention Google Sitemaps:
Once the Sitemap file is enabled on the Search Engines page, merchants will also be able to proactively inform search engines about pages in their store by submitting their Sitemap file to programs such as Google Sitemaps.
I mean, a Yahoo! blog, mentioning only a Google service (with a link too) for a new feature they released. Yahoo! has a sitemap submission page too [insert author of that post here], you know.
