Beta Changelog
ScriptCat's version releases are divided into two main branches: stable releases and pre-release versions. For the stable release changelog, please see: Changelog
Pre-release versions are released before the official stable version. They are typically used to test new features. Pre-release version numbers contain a pre-release identifier, for example:
1.0.0-beta.1.
You can obtain pre-release versions from the Release page or from the extension store pages below:
Additionally, besides pre-releases, ScriptCat builds the extension on Github Action after each code commit is merged to the main branch. If you want to experience the latest features or fixes, you can download them from the Github Action page.
