CDemu has been updated recently to version 2.0.0 bringing more new features and changes. As a reminder, CDemu is a software suite that allows users to mount disk images (CD/DVD) in Linux-based systems. It has  some similarities with DAEMON Tools for Windows. CDemu consists of a daemon, kernel module, library, and a GTK client.

For easier use of CDemu, Cdemu Tray has been created which is a GUI that allows users to mount/unmount disk images like you do in DAEMON Tools:

Also, For Ubuntu Unity you can use the gCDEmu Indicator that will help you mount your ISO's from the upper panel with support of notifications:

Here are some of the changes in CDemu 2.0.0:

Autotools is replaced with CMake 
Adding DMG, CSO, and  ISZ file filters 
Adding support  for the GBI format 
Support for GObject introspection 
Better caching 
Support for GZIP and XZ compressed images 
 Support for ECM'ed files was added 
The CIF parser was improved
