A raft of new features were added in the recent iOs 14.3 update.
Two stand out for me.
Firstly the new Apple Raw file format. Since about 2017 or 2018 I used a 3rd party app that captured DNG files as I went. Called ProCamera. Now Apple natively supports DNG in camera.
Scroll down to formats.
Toggle Apple ProRaw on
The second is a setting about app tracking and privacy. You need to activate this setting to enable sites like Facebook to track your movements online. It is off by default. Personally I would leave it that way. More on the Mac Rumours website
Scroll and tap Tracking.
Make sure the toggle is grey. No sites or apps can track your movements.
