Public Beta Releases - 1.4.01

Public Beta Release - 1.4.01

In order to improve the quality and stability of public release, we are introducing a “Public Beta” period for new LightBurn 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 users to address any issues at this public beta stage before doing a general public release.

Reporting Bugs

If you encounter a bug in a public beta, please let us know by sending an email to with as much information as you can recall - ideally, provide the steps required to reproduce the issue, and attach any screenshots, crash logs, or images as needed. Please put ‘Public Beta’ in the subject line of your email.

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 public release version from the Trial/Download page .


Public Betas can be downloaded from here .
