+
+It's been just over two weeks since the release of [Godot 4.5](/releases/4.5/), and the overwhelmingly positive community response has been an absolute treat to behold! Our hard-working contributors have taken this energy to kick-start the development phase of Godot 4.6, resulting in our [first snapshot](/article/dev-snapshot-godot-4-6-dev-1/) coming out earlier this week.
+
+In saying that, the main focus was always going to be hammering out newly reported regressions encountered in the 4.5 release, and integrating any fixes deemed too risky to merge at the time. As such, we've already prepared a healthy number of regression fixes for a 4.5.1 maintenance release. This release candidate is intended to validate the fixes in an environment isolated from the new enhancements and features that 4.6 is already boasting. Your testing is crucial to detect and squash any new issues that weren't present in 4.5-stable, in order to ensure that this hotfix is as clean of an upgrade as possible.
+
+Please consider [supporting the project financially](#support), 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 issues
+
+During the Release Candidate stage, we focus exclusively on solving showstopping regressions (i.e. something that worked in a previous release is now broken, without workaround). You can have a look at our current [list of regressions and significant issues](https://github.com/orgs/godotengine/projects/61) which we aim to address before releasing 4.5.1. This list is dynamic and will be updated if we discover new showstopping issues after more users start testing the RC snapshots.
+
+With every release we accept that there are going to be various issues, which have already been reported but haven't been fixed yet. See the GitHub issue tracker for a complete list of [known bugs](https://github.com/godotengine/godot/issues?q=is%3Aissue+is%3Aopen+label%3Abug+).
+
+## Bug reports
+
+As a tester, we encourage you to [open bug reports](https://github.com/godotengine/godot/issues) if you experience issues with this release. Please check the [existing issues on GitHub](https://github.com/godotengine/godot/issues) 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).
+
