This is the latest stable released version of N.I.N.A.
The version did undergo a fair amount of testing and is stable to use for your imaging runs.
Version 1.10 HF3
The nightly builds contain the latest development snapshots. These contain the ongoing enhancements, bugfixes and new features that are upcoming for the next released version. These builds (especially in early stages) can be unreliable for imaging runs and should only be used to try out the upcoming features and to provide early feedback! The nightly builds will progress quickly and when using these staying on outdated builds is strongly discouraged!
