More information about this update, including detailed information about the security content of OS X 10.10.3, is available in Apple’s support doc.
Photos for Mac sports professional-level and advanced fine-tuning tools such as granular color correction. And if you use iCloud Photo Library, the app will store all your photos and videos in the cloud in their original resolution.
You can then elect to download full-resolution or device-optimized content on a per-device basis in Settings > iCloud > Photos. With iCloud Photo Library enabled, your edits and other changes made to photos instantly sync between all your devices.
This includes deleting a photo or video, which automatically removes copies from both the cloud and all your synced devices. Thankfully, you have about a month to retrieve delete content from the cloud should you change your mind.
Apple gives each free iCloud account five gigabytes of storage, with paid tiers available at 20GB/200GB/500GB/1TB for $0.99/$3.99/$9.99/$19.99 per month.
In addition to OS X 10.10.3 update, the company also posted the OS X Yosemite Recovery Update 1.0 which improves the reliability of Yosemite Recovery when restoring from a Time Machine backup.
