Safari 11.1 in macOS High Sierra 10.13.4 and iOS 11.3 Introduces New Features and Optimizations

by

safari iconBoth macOS High Sierra 10.13.4 and iOS 11.3 ship with an updated version of Safari, Safari 11.1. Safari 11.1 incorporates many new features that have been in testing in Apple's Safari Preview browser, introducing new web APIs, security improvements, media changes, and more.

Details on the Safari 11.1 update were shared by Apple's Ricky Mondello, and a full change log is available from Apple's developer website.

Animated GIFs can be replaced with silent videos in Safari 11.1 to result in smaller downloads, more available colors, and better decoding performance.

In iOS 11.3, Password AutoFill for apps works in web views within apps, which will make it easier to log into a site without having to copy and paste your password each time. Web apps that are saved to the Home screen on iOS devices and web pages in SFSafariViewController can also now use the camera to capture images.

A new security change provides a "Website Not Secure" warning when a user clicks a credit card field or password entry box on an insecure page, and

Intelligent Tracking Prevention, which prevents websites from tracking you around the web, has been improved in Safari 11.1, and there's a new improved Safari Reader extraction engine to improve the Safari Reader experience.

Service Workers, new in Safari 11, are designed to allow background scripts to power offline web applications, and there are several other new APIs including Payment Request API, Directory Upload, Beacon API, HTMLImageElement.decode(), and an updated Clipboard API.

Safari 11.1 is bundled in to iOS 11.3 and macOS High Sierra 10.13.4, both of which are available for developers starting today. Apple plans to release iOS 11.3 and macOS High Sierra 10.13.4 public betas in the near future.

A step in the right direction. There is nothing I would like to see Apple do more than to overhaul Keychain into a full-featured password manager app and give 1Password a run for their money.

I'd definitely like to see Keychain itself remain a secure vault managed by the system, as it's always been. But definitely overhaul Keychain Access to make it a more consumer-friendly app. I use it dozens of times a day to grab saved passwords and secure notes. I don't need third-party solutions. But it still feels like a neglected app by Apple that hasn't been updated in years. It works, there's no bugs, but it's just not consumer-friendly. Most Mac users that I know don't even know about it.

More security features and stronger anti-tracking software update is always welcome. I agree with Keychain being neglected and should be overhauled to mimic or even become better than 1Password as a secure vault for sensitive information.

Safari has become a really great browser and any improvements are always welcome. Looking forward to 11.1 once the final 10.13.4 release is out.

I love and use Safari’s touch bar features all the time. Especially PIP to the bottom right corner, scrubbing, etc. The touch bar has gotten as bad rap but once you get used to it and as its capabilities further evolve, I’m sure more people will come to love it.

To my opinion, if barely anyone knows about the Keychain app, it points out towards two things:

- users may not know they need it (it allows for more difficult passwords than one naturally would be inclined to use, especially if you take the suggested passwords option into the picture)

- the app is not user friendly as to inviting to use, meaning the full potential is not properly marketed. It is currenty an app that appeals to nerds and security aware people, most probably two names for one group of people.

I am a hefty and satisfied user of the app, but the above two thread comments (by coolfactor and hefty) are making a point: what if it were an app that indeed was more of a valued and less boring feature that appeals a larger public... hmm...

I am inclined to think that it has to extend the potential of our own memory, in an as less obtrusive way as possible. Perhaps that indeed means Apple is dealing with it in a way that fits my expectations.

A most relevant point of thought to me is the unification of passwords and autofill info. I cannot understand why seemingly, passwords are to be separately saved inside the preferences of Safari while these are also in the keychain (app and file I mean). It appears that this info is synced within Safari trough iCloud, separately and independently of the keychain sync in iCloud, be that feature activated or not.

To take a walk in the backyard of the topic, I also find it similarly irrelevant to have a system keychain and an login keychain within the keychain app. Double items are to be found there yet again.

And to finish off this train of thought: what are passwords on iOS doing in the Settings app, and why not place it parallel inside Mac OS, or the other way around...?

The subject defines touches some nerves ;)
