First off, AppleInsider has a few new details about the current Photos for OS X beta. Manual image zoom controls have been added to iCloud.com, as well as email sharing. Photos for OS X will launch sometime later this year, and will bring iPhoto and Aperture together, along with full iCloud integration.
Next, OS X Yosemite 10.10.2 has been released, with quite a few fixes and some updates/new features. iCloud Drive can now be browsed from within Time Machine, which could mean that you can go back and look at previous file versions stored in iCloud.
Three interesting updates/releases for Mac users – LastPass, the password manager, has finally been released for OS X users, and iPhoto Library Manager 4.1.11 and CrashPlan 3.7 (a cross-platform online/cloud backup service) have been released.
