as linked by @mparillo, there is no need to update a net-edition, because the latest packages are always downloaded before system installation. additionally, the list of packages you can choose from is taken from a github website, which i can edit. when i update this website, even manjaro net/lxqt 17.0 “sees” that updated list and can install those packages.
i have done a build of manjaro net/lxqt 17.0.3 just to see, whether the build process still works. i will do a build of 17.0.5 soon and check it.
are you interested in the fixed issues in calamares (e.g. fixed BTRFS install) compared to version 17.0.2 (because these will be the only differences)?
if this is the case, i can release it as soon as the current fast releases of bugfixes stop a week or two.
