They should count as revised editions, I think.
These versions are all trying to eliminate certain BUGs. Under normal circumstances, there's no need for everyone to use them. Everyone can use the versions on GNA for daily use. As for the ones on jot, they are all test versions.
Only when you run into problems do you need to download the daily updated test versions.
I'm also considering whether I should, as bean said, re-release an official 0.4.3 version, because the current official 0.4.3 really does have a public, obvious problem: on ext2 partitions it may fail to find the grldr file. Of course, the latest test version fixes this BUG.
So everyone still needs to test these versions, because they may become the prelude to a re-released official 0.4.3 version in the future.
Of course, if you aren't too willing to test, then you don't have to.
