After almost one year of development, the master branch (future Godot 3.0) is mostly feature-complete and ready for broader testing by the Godot community. We are therefore releasing a first alpha snapshot for existing users to play with and report bugs.
IMPORTANT: This is an alpha build, which means that it is not suitable for use in production, nor for press reviews of what Godot 3.0 would be on its release.
There is still a long way of bug fixing and usability improvement until we can release the stable version, and this release comes with virtually no documentation. This release is exclusively for testers who are already familiar with Godot and can report the issues they experience on GitHub.
Note: New Godot users should not use this build to start their learning. Godot 2.1 is still supported and well documented
Now, there are still some cool features that can already be played with in this alpha1 build, and we are looking forward to seeing what you will come up with using the new 3D renderer. There is no exhaustive listing of all the new features to experiment with, but you can read past articles of this blog and check Juan's Twitter feed for some teasers :)
Please use the community channels to discuss with existing users and learn how to use the new workflows of Godot 3.0 - as of this writing there is almost no documentation on the new features, but this alpha1 build should serve as a starting point for documentation writers.
The download links are not featured on the Download page for now to avoid confusion for new users. Instead, browse one of our mirrors and download the editor binary for your platform and the export templates archive:
Also clone the godot-demo-projects repository to have demos to play with. Some of them might still need adjustments due to recent changes in the master branch, feel free to report any issue.
There are still many open bug reports for the 3.0 milestone, which means that we are aware of many bugs already. We still release this snapshot to get some early feedback while we work on fixing the known issues.
As a tester, you are encouraged to open bug reports if you experience issues with alpha1. Please check first the existing issues, using the search function with relevant keywords, to ensure that the bug you experience is not known already.
You can also consult this list of known issues, which is a hand-picked list of the most visible problems you will likely encounter.
We can already see many questions coming regarding this development snapshot, so here are some answers.
When it's ready. We're all working on our free time on this project, and can't commit to a given deadline. We consider the master branch to be feature-complete, and we are now working on fixing bugs in the new features and enhancing the usability of the new workflows. Depending on how it goes, we may be able to release 3.0 stable in a couple of months.
No, the alpha1 build does not contain the Mono/C# module yet. It should soon be merged in the master branch, so it might be available in alpha2. The 3.0 stable release will support C#, the integration is almost ready.
No, and there are no plans for Vulkan support for the time being. Our resources are too limited to focus on too many renderers at the same time, and the new OpenGL ES 3.0 / OpenGL 3.3 renderer of this build was already a huge refactor. Vulkan being only relevant for a small fraction of our users, it's low priority for now.
Projects from Godot 2.1 are not compatible with Godot 3.0, as many things changed in the Godot API as well as in GDScript. There is no porting guide for now, but there is an export tool in Godot 2.1.3 and later which can be used to export 2.1 games to the formats expected for Godot 3.0.
Since the master branch is a moving target, the exporter in Godot 2.1.3 is already outdated and won't work as smoothly as it should. Your best bet is to compile the 2.1 branch yourself to use the latest version of the exporter, and report any issue you experience with it.
As for most features, it lacks documentation for now. Still, you will find some infos on the godot_headers main repository, as well as the CPP bindings. You can use the Q&A with the gdnative tag to mark your questions; Thomas (Karroffel) will do all he can to help you get started.
Yes, as the name "alpha1" suggests, we plan to have newer builds regularly to bring the latest state of the master branch. Depending on the user feedback we get, we might make weekly releases or biweekly if it proves too much burden.
