iOS 10.3.3 Beta 1 released for iPhone & iPad

RELEASE NOTES:
Managed and Shared Devices
The ability to update devices from a remote server is in development and may not yet work as expected.

openURL
When a third party application invokes openURL: on a tel://, facetime://, or facetime-audio:// URL, iOS displays a prompt and requires user confirmation before dialing.

SOS
SOS is only supported in India.

WebKit
Safari now supports the prefers-reduced-motion media query. This query allows a web developer to provide alternate page styles for users who are sensitive to large areas of motion. Users can change their preference for reduced motion in the Accessibility section of System Preferences.
The iOS 10.3 update removes support for SHA-1 signed certificates used for Transport Layer Security (TLS) in Safari and WebKit that are issued from a root Certification Authority (CA) included in the operating system default trust store. All other TLS connections will continue to support SHA-1 signed certificates until late 2017. SHA-1 signed root CA certificates, enterprise- distributed SHA-1 certificates, and user-installed SHA-1 certificates are not affected by this change.
