Dropbox joins the onslaught of app updates today, following Apple's release of iOS 9. The new version of the cloud-based storage provider's iOS client is labeled 4.0, and it brings about a number of improvements, including support for some of iOS 9's new features.
Folks with the new Dropbox app on iOS 9 will see Dropbox files in Spotlight search results. This includes recently used files, plus any marked for offline access, and a quick tap will open them in-app. Additionally, any Dropbox link you tap on will open within the app.
