Apple released an update to Aperture, which brings it to version 3.5.1 - It's a free update which we're advised puts right several flaws, including Temperature & Tint White Balance which were informed now functions correctly. Apple is also seeding two new Safari betas - one for Lion and Mountain Lion (10.7 and 10.8 respectively) and one for OS X Mavericks (10.9). The Safari betas, which are not yet officially released, focus on viewing and annotating PDF files, along with password autofill troubleshooting.
The respective Safari betas are number 6.1.1 (for Lion and Mountain Lion) and 7.0.1 (for Mavericks), suggesting that they will be released soon. In addition to further PDF and password testing, Apple has asked developers to focus efforts on Web Inspector functions alongside accessibility features and general website compatibility. The Aperture update, available for all Aperture 3.x users, resolves issues with face-detection overlays and addresses an issue with metadata field entry when arrowing between photos, along with the usual stability improvements.
The Safari betas are available from the Mac Developer Center on Apple's website. The updated Aperture 3.5.1 is available through Software Update or the Mac App Store.
