There is very little left for the new version of Linux Mint 18 to come out and while this is happening, Cinnamon, the default desktop of the project has a new maintenance release more than inclusion of news.
Cinnamon 3.0.4 is a version that fixes many bugs and many errors that the desktop is having. It is not the first maintenance version but rather the fourth version that comes out in order to fix many bugs and make the desktop more useful and usable for all users. Cinnamon 3 is a version that came out a few weeks ago for the rest from distributions other than Linux Mint, this desktop can be installed and used on Ubuntu 16.04 or any other version of Ubuntu as well as in any Gnu / Linux distribution.
Cinnamon 3.0.4 fixes issues related to menu and sound applets
In this version, Cinnamon 3.0.4 fixes errors related to sound and menu applets. In the last few days several users have reported that Cinnamon 3 does not render graphical transitions well when applets are moved or removed. The same is also true for the menu applet. Another change in this new version is the modification of the application search engine that now allows you to avoid accents and capital letters when searching for applications.
Despite all this, Cinnamon 3 still has problems to fix and I hope that it will be solved before launching the new Linux Mint 18 distribution. So, for several days I have tried this new desktop and I have run into the problem of not having a shutdown button, but I had to close the session and from there shut down the system. It is a silly mistake that I hope will be corrected, but one that many users will not forgive. In any case the Linux Mint team is not idle and is working on improving this popular desktop, so we will see positive results in a few days, don't you think?
Waiting for Linux mint 18
I don't get the shutdown button either, I thought it was just my case
Try entering these commands in Terminal:
gsettings set org.cinnamon.desktop.session settings-daemon-uses-logind true
gsettings set org.cinnamon.desktop.session session-manager-uses-logind true
gsettings set org.cinnamon.desktop.session screensaver-uses-logind false
thanks, it worked.
When does it come out?
I also had the problem of the shutdown button, I mentioned that in the tutorial on how to install Cinnamon in Ubuntu 16.04, a user gave me the solution to the problem, a link in Ubuntu Ask with someone asking about the problem, and the commands that are there to introduce to solve them, these are:
gsettings set org.cinnamon.desktop.session settings-daemon-uses-logind true
gsettings set org.cinnamon.desktop.session session-manager-uses-logind true
gsettings set org.cinnamon.desktop.session screensaver-uses-logind false
try placing the commands and this appears: There is no schema "org.cinnamon.desktop.session"
