Upgrading to the Latest OSCAR Release

If you already have OSCAR installed (cf. installation guide) and wish to upgrade to OSCAR v1.3.1, the latest stable release, follow the instructions below. If you encounter any issues, do not hesitate to contact us.

Upgrade OSCAR

Open a terminal and launch Julia:
```
julia
```
At the Julia prompt, update the OSCAR package:
```
using Pkg
Pkg.update("Oscar")
```
Verify the installed version – it should report OSCAR v1.3.1 – as follows:
```
using Oscar
Oscar.versioninfo()
```

Troubleshooting the OSCAR Upgrade

OSCAR depends on several actively developed packages. To ensure full compatibility — especially if you experience any issues — we recommend updating all your packages:

Pkg.update()

Then restart Julia and check the OSCAR version (it should be OSCAR v1.3.1):

using Oscar
Oscar.versioninfo()

If the version is not updated or you encounter any failures during the upgrade, please contact us for assistance.

Upgrade Julia

For performance and feature improvements, we recommend upgrading Julia to the latest stable version.

If you installed Julia using juliaup (the recommended method), upgrading is as simple as running:

juliaup up

If you’re not using juliaup, please refer to the official Julia installation instructions for upgrade guidance.

After upgrading Julia, you will need to reinstall OSCAR in the new Julia environment. In most cases, the installation will reuse existing OSCAR files and complete relatively quickly. However, this cannot be guaranteed and may depend on your specific setup.
