is there any general question was there any reason to choosing, 5.1.1 for up to date and not 5.2, yes the reason was that 5.2 was not out when we did the upgrade crazy and 5.2 just came out and, not gonna lie like the thinking of updating again this close, well updating this close to release is not going to happen first of all but just the fact that like thinking of like updating to 5.2 at all is just like ah we got really burned on doing the update yeah, but there are stuff in 5.2 that we are interested in and theoretically updating from 5.1 to 5.3 shouldn't be as big as 4.425 but, famous last words we also thought the update to five wouldn't be, that big it was really big, so a jury's still out but it won't happen for updated at all like we're not gonna update front friend, for updated that's for sure too big of a commitment too big in it
