They can also be automatically sorted in various ways: By name, by size, by type or by modified date.
You can also change desktop icon sizes with a click of a button, and desktop icons are now handled in their own separate process, which isn’t tied to other nemo windows.

Cinnamon Spices

Cinnamon Spices website was rewritten from scratch
The goal wasn’t only to make it look better. More secure than before and attempting to guarantee better quality and better compatibility
The site supports oauth authentication via Google, Facebook and Github so you can comment and like your favorite spices
The maintenance of the spices themselves was moved to Github and every single change is now reviewed by the Linux Mint team to guarantee spices cannot be used for malicious purposes
Anyone can provide bug fixes and translations to Cinnamon spices
Both the Authors and the Linux Mint team is now directly involved in the maintenance of all Cinnamon spices. Many spices were removed, many were fixed, many were updated and the team is now able to add support to spices not only for current versions of Cinnamon but even for upcoming ones.
We’re getting closer and closer to a situation where everything “just works”, where quality spices are easy to find and where they work in your language.

Installed today
Needs some work – but is still in dev.
Adds PPA’s, etc like welcome. But a 3rd party – may want to check what it is adding.
Seems to need a lot of BG access – expected.
Some of the option like repairing PPA actually rely on other tools that need to be installed from 3rd party PPA’s – but no dependency, just not found – like the y-ppa-manager, but available in the options to install.

Some updates for the other OS’s like mac notifications
30 some bug fixes
To avoid over-prompting users, Chrome will now temp stop an origin from requesting a permission following the third dismissal of that permission request.
Some cosmetic changes like a material design overhaul in the settings page
The Image Capture API allows higher resolution images than before. That means developers get full control over camera settings such as zoom, ISO, and white balance.
Seems to be mostly developer related updated
Stuff like:
- - - vTouch events
    - new worker-src Content Security Policy directive
    - vgetInstalledRelatedApps function (smartly consolidate push notifications)
    - Etc
