Important notice to residents of California and Colorado

As a consequence of recent legislative activity in California and Colorado:

California residents may no longer use DB48x after Jan 1st, 2027.
Colorado residents may no longer use DB48x after Jan 1st, 2028.

DB48x is probably an operating system under these laws. However, it does not, cannot and will not implement age verification.
