Linux Lite 3.8 Final Released

[kissbaby3]

i know i asked this before, but now that Linux Lite 3.8 is now released as final, when will the 3.8 life cycle end (support, updates, security updates) ?. will all end when 4.0 gets released as final ?........ also when i upgrade from 3.6 to 3.8, will i lose all my saved files (video clips, photos, so and and so on) ?, yes i did a back up of all my files . 

so far i really like this
