We are glad to announce that ABP 9.1 stable version has been released today.

What's New With Version 9.1?

All the new features were explained in detail in the 9.1 RC Announcement Post, so there is no need to review them again. You can check it out for more details.

Getting Started with 9.1

Creating New Solutions

You can check the Get Started page to see how to get started with ABP. You can either download ABP Studio (recommended, if you prefer a user-friendly GUI application - desktop application) or use the ABP CLI to create new solutions.

By default, ABP Studio uses stable versions to create solutions. Therefore, it will be creating the solution with the latest stable version, which is v9.1 for now, so you don't need to specify the version.

How to Upgrade an Existing Solution

You can upgrade your existing solutions with either ABP Studio or ABP CLI. In the following sections, both approaches are explained:

Upgrading via ABP Studio

If you are already using the ABP Studio, you can upgrade it to the latest version to align it with ABP v9.1. ABP Studio periodically checks for updates in the background, and when a new version of ABP Studio is available, you will be notified through a modal. Then, you can update it by confirming the opened modal. See the documentation for more info.

After upgrading the ABP Studio, then you can open your solution in the application, and simply click the Upgrade ABP Packages action button to instantly upgrade your solution:

Upgrading via ABP CLI

Alternatively, you can upgrade your existing solution via ABP CLI. First, you need to install the ABP CLI or upgrade it to the latest version.

If you haven't installed it yet, you can run the following command:

dotnet tool install -g Volo.Abp.Studio.Cli

Or to update the existing CLI, you can run the following command:

dotnet tool update -g Volo.Abp.Studio.Cli

After installing/updating the ABP CLI, you can use the update command to update all the ABP related NuGet and NPM packages in your solution as follows:

abp update

You can run this command in the root folder of your solution to update all ABP related packages.
