In addition to news about the upcoming Metal Gear Solid level and character packs, Media Molecule has also released a 67MB patch that upgrades LittleBigPlanet to version 1.07. No patch details have been released yet, so here's what we've noticed so far:
An in-game LittleBigStore! It functions as its own planet, and if you've already purchased the equipment, you can swap into the whole costume here.
New search options (just to the right of Community). You can now navigate through user-generated content by highest rated levels, the most hearted levels, the newest levels and the busiest levels, as well as searching with text or tags.
A "save level as" option when creating levels that lets you move the creation to whichever slot you would like.
No additional Stephen Fry narration (unfortunately).
If you notice anything else, let us know. We'll update with the official patch notes when and if they're released.
