We saw the release of Godot 4.5 less than a month ago, and have already been absolutely overwhelmed with the positive reception. Since then, our team has been hard at work on the development phase of Godot 4.6 (and subsequently its first snapshot), and ensuring that any new regressions/bugs reported after the release of 4.5 are dealt with swiftly. The community has done an absolutely fantastic job at helping our team find and squash all of those aforementioned issues, and paved the way for us to deliver 4.5.1-stable for you today!

Maintenance releases are expected to be safe for an upgrade, but we recommend to always make backups, or use a version control system such as Git, to preserve your projects in case of corruption or data loss.

Please consider supporting the project financially, if you are able. Godot is maintained by the efforts of volunteers and a small team of paid contributors. Your donations go towards sponsoring their work and ensuring they can dedicate their undivided attention to the needs of the project.

Known incompatibilities

As of now, there are no known incompatibilities with the previous Godot 4.5 release. We encourage all users to upgrade to 4.5.1.

If you experience any unexpected behavior change in your projects after upgrading to 4.5.1, please file an issue on GitHub.

Bug reports

As a tester, we encourage you to open bug reports if you experience issues with this release. Please check the existing issues on GitHub first, using the search function with relevant keywords, to ensure that the bug you experience is not already known.

In particular, any change that would cause a regression in your projects is very important to report (e.g. if something that worked fine in previous 4.x releases, but no longer works in this snapshot).
