General changes:
- Increased intensity of touch screen vibration (a bit too much to my liking)
- All menus now have kinetic scrolling, also the main menu
- You can now set your default web browser to be Opera Mobile if you have it installed
- Enhanced performance while scrolling through lists (smoother)
- Windows 7 Device Stage support
Browser changes:
- Version v7.2 (still crashes sometimes though)
- Send URL option (over bluetooth, mail, message ...)
- Option to enable history list
- Separate access point for webfeeds
- Kinetic scrolling all over the browser
- Browser goes fullscreen automatically and shows title bar only when loading
Application changes:
- Ovi Sync 2.0 is now integrated
- Flashlite is upgraded to 3.1.7
- Quick Office v4.2 is apparently distributed with the update, but does not show up on my phone - perhaps the memory was full (I got a system error when booting after the update)
Music player changes:
- Music player 'hides' by default instead of exiting
- Album art visible when scrolling through songs
- Using the scrollbar to scroll songs list shows the initial letter of the song, making searching easier
- Smoother scrolling
Camera changes:
- Camera app opens instantly, shortening the time between pushing the button to open and to take a picture
Calendar:
- Better performance in week view (when scrolling)
- Still very buggy. Reproduceable bug: tap the left/right arrows a bit in week view and the app will crash.
Some things I found on dailymobile but I don't know what they're talking about because I don't see any changes:
- Ovi Store upgraded to v1.5.6
- Ovi Contacts upgraded to v1.50.8
- Lifecasting (with Maps 3.0T SR3.0)
- Gimlet Touch 2.2 (the e-mail app)
- Enable Side lock Key functionality during Swipe UI (doesn't seem to behave differently than in v40)
- Cherry v2.1 (settings assistant, didn't try this one out)
- Rihanna service launcher (if you don't get this, get it from the OVI store)
- Workaround for Niagara (SMD) display module for DFS52.50 based products
