MX-16 was released some days ago. I just downloaded the 64-bit version and right now I am downloading the 32 bit one. Then, I'll make the live USBs from the ISOs.
What's different this time? MX comes with a lot of custom tools:
MX Original Apps to make common tasks easier
Create Live USB
Check Apt GPG
Debian Backports installer
Test Repo installer
One-click Extras with Package Installer
Children: Preschool, Primary, etc.
Graphics: ImageMagik, Inkscape, etc.
Network: Skype, Dropbox, etc.
Office: GnuCash, Adobe Reader, Calibre, etc.
System: KDE, LXDE, MATE, etc.
Audio: Audacity, DeaDBeeF, Pithos, etc.
Video: DVDStyler, MPlayer, OpenShot, etc
Many new Live boot options
Run in Live mode in 10 languages
Easy Live-remaster to make a custom LiveUSB or your own version to distribute as an ISO
Three forms of Live persistence (i.e., what files are kept on the LiveUSB)
Easy "frugal" installation option
Simple creation of custom snapshots (as easy as: add/remove packages, change settings, take a snapshot)
Automatic check of LiveUSB file systems for integrity
Live kernel installer
Live usb maker
I am eager to install and test this new release!
