This post is slightly late to the party, but Adobe has now released the full version of Lightroom 5.2. It is quite a big update on the original LR5 release. Full details are on the Lightroom Journal.
In addition, the company has released the Photographer's version of the Creative Cloud. For owners of CS3 or above, this gives Lightroom, Photoshop CC, access to Behance and 20GB of storage for $9.99/month. The price is fixed as long as it is taken up before the end of December.
Full details are on Adobe's site.
