New and changed features in the 25.04 SDK
The 25.04 release of the Azure Sphere SDK includes the following changes:
Addition of SDK support for Ubuntu 24.04 LTS
The 25.04 SDK adds support for Ubuntu 24.04 LTS. The Linux SDK installer can determine the LTS version of Ubuntu you are running and download and install the appropriate SDK.
End of SDK support for Ubuntu 20.04 LTS
Ubuntu 20.04 is no longer supported by Canonical as of May 2025, so we have removed support for Ubuntu 20.04 from the Azure Sphere SDK.
Error message update for azsphere register-user command
The azsphere register-user command in the Azure Sphere (Legacy) CLI is no longer supported. We have updated the error message in case this command is used to be clearer. Alternative methods should be used to register Azure Sphere (Legacy) users.
Addition of message regarding retirement of Azure Sphere (Legacy)
The Azure Sphere (Legacy) interfaces, including the Azure Sphere (Legacy) API (also known as PAPI) and the Azure Sphere (Legacy) CLI (also known as azsphere), will be retired on 27 September 2027.
A retirement message has been added to the Azure Sphere CLI and will be displayed when you run the --help parameter for a command.
For more information about retirement and how to migrate to Azure Sphere (Integrated), see this blog post.
Removal of Azure Sphere Classic CLI
The Azure Sphere classic CLI is an old version of the CLI that predated the Legacy CLI. We announced retirement of this in 2023, and this version is now retired and removed from the SDK. We recommend using Azure Sphere (Integrated).
Updates to the azure-sphere extension for Azure CLI
The azure-sphere extension for the Azure CLI version 1.0.2 is now available. This includes support for the az sphere image-package pack-application command and other improvements.
Updates to Visual Studio and Visual Studio Code extensions
This release includes the following updates to the Azure Sphere extensions for Visual Studio and for Visual Studio Code:
- Updates to the user interfaces to support the Azure Sphere extension for the Azure CLI
- Bug fixes
