The preview versions are released ~2 weeks before releasing a major or feature version of the ABP Framework. They are released for developers to try and provide feedback to have more stable versions.
Versioning of a preview release is like that:
More than one preview releases (like 3.1.0-rc.2 and 3.1.0-rc.3) might be published until the stable version (like 3.1.0).
Using the Preview Versions
To create a project for testing the preview version, you can select the "preview" option on the download page or use the "--preview" parameter with the ABP CLI new command:
abp new Acme.BookStore --preview
This command will create a new project using the latest preview NuGet packages, NPM packages and the solution template. Whenever the stable version is released, you can switch to the stable version for your solution using the
abp switch-to-stable command in the root folder of your solution.
If you already have a solution and want to use/test the latest preview version, use the following ABP CLI command in the root folder of your solution.
You can return back to the latest stable using the
abp switch-to-stable command later.
You can open an issue on the GitHub repository, if you find a bug or want to provide any kind of feedback.
