Public Release Candidates
In order to improve the quality and stability of official releases, we offer a “Release Candidate” period for new releases.
We’ll test to the point we normally would before a release, then make the new version available here for anyone who wants to try it. We’ll gather feedback from those users to address any issues we missed before doing a general release.

Using Pre-Release Builds
LightBurn pre-releases can now be installed side-by-side with the full release version!
On Windows, all Release Candidate builds will now install to a directory with a _PreRelease suffix by default.
The application will also show up in your Start Menu as LightBurn (PreRelease)
On Mac the app simply has the _PreRelease suffix in the name.
Just like with the installation directory, the preferences are now stored in a directory with a _PreRelease suffix. The first time installing a pre-release version of LightBurn it will prompt you to import the preferences from your full release install.
You can also use the User Bundles feature later to transfer your existing release preferences to your pre-release instance of the software.
Reporting Bugs
If you encounter a bug in a public beta, please let us know by sending an email to betasupport@lightburnsoftware.com with as much information as you can recall about what you were doing so we can try to reproduce it and fix it.
The standard licensing rules apply - you'll need to have a current license key to run these (or be in an active trial period). If you have any issues while using a beta, you can just install whatever version you were using before, or grab the current released version from the Trial/Download page.
