Welcome to the 4th 4.0 beta!

To catch up with the changes in 4.0, please read the post about the 4.0 beta 1.

Installation and feedback

To test this beta, download the required installation files from this download page, or enable the setting "Update to Pre-releases" inside Blockbench. Enabling this setting will tell Blockbench to always update to the latest pre-release, allowing you to test the latest features. Please note that pre-release versions may be unstable and have more issues than release versions.

Please report issues you find in the beta, make sure to specify the correct version.

Also, please let me know any feedback you might have, especially regarding poly mesh editing and the new UV editor, so that I can make sure to make them as intuitive as possible before release. We can talk about feedback in #bb-feedback on the Discord server.
