Release notes\r
\r
Dictionary\r
Known Issue\r
A user updating to an iOS 9 GM build from a seed build may see duplicate dictionaries in the\r
definition dictionary list if the user switched primary language, added secondary languages, or\r
added new keyboards.\r
Workaround: To remove the duplicate dictionaries, go to the definition dictionary list, swipe the\r
dictionary, and tap the Delete button.\r
Keyboards\r
Known Issues\r
• If using a third-party keyboard as the default keyboard, you will be unable to enter your\r
user name and password in a Captive Wi-Fi login.\r
Workaround: Leave the login screen, go to a different app and invoke the Apple system\r
keyboard, then return to the Captive Wi-Fi login screen and use the system keyboard.\r
• Smiley emoji may be not rendered correctly when input from the Frequently Used\r
category\r
Networking\r
Notes\r
• Explicit Congestion Notification (ECN) is enabled by default on Wi-Fi and on select\r
carriers. This is designed to reduce network delays and reduce packet loss.\r
• The ability to synthesize NAT64 IPv6 addresses from IPv4 literals was added\r
to getaddrinfo.\r
Safari\r
Notes\r
• SFSafariViewController now supports 3rd party Action extensions. Any Action\r
extension that works in Safari will also work in SFSafariViewController.\r
• Long tapping the Reload button in Safari View Controller now gives options to Reload\r
Without Content Blockers and Request Desktop Site, as it does in Safari.\r
• Safari View Controller can now be dismissed using an edge swipe. You must rebuild your\r
app against the iOS 9.2 SDK or later to take advantage of this new behavior.
