From MX dev Adrian:
"Snapshots for May are up. Nothing special, about 30 packages were updated, among them a Firefox update 59->60, and an installer bugfix for installing MX Linux on ESP"
Sourforge link: http://bit.ly/mx-monthly
or get the snapshots links at https://mxlinux.org/download-links
The Monthly Snapshots are not meant for people who already have MX installed (you folks already get the updates via the repos). It's for people who want to run Live environment with the latest versions and installing using the latest installer (without needing to do potentially massive updates after installation from the original Official Release). Major new distro-wide features are not introduced in Monthly Snapshots, although new features might become available through the regular update process. There is a minimum of testing done on the Monthly Snapshots, so be sure to report any problems in the forum.
