mga5??

At this moment, I am doing an upgrade from mageia 3 to mageia 4. I am doing this as an online upgrade, following the instruction here: https://wiki.mageia.org/en/Mageia_4_Release_Notes
But I am receiving a large number of packages labeled mga5, for instance, this one:
media/core/release/sharutils-4.14-1.mga5.x86_64.rpm
Why is this? Do I somehow have cauldron (or cooker...or whatever) packages coming in? Am I going to have an unstable system when I reboot?
