Nightly Build

In kernel: Nightly Build is a version of the Linux kernel compiled and released daily.

Nightly builds are a good thing as they provide immediate feedback to developers if they break the build as it allows them to identify and fix issues as early as possible. This can help improve software quality and reduce the risk of bugs. Having a nightly build means the software is stable and likely to be developed for new users. It's like building a house a little each day, allowing you to identify and solve problems as they arise.

NightlyBuild, it is usually because there are more fixes to apply, so it is applied little by little according to the dev's time. So when it's the way the dev wants it, it will be a Release. Nightly builds make it easier to release new versions of software. This is because the software is already being built regularly, so there is less risk of problems in the release process.
