Hi,
We have added support for the SDK 2.1.0 a while ago. The 2.1.1 version got added just now.
In general, if you would like to use a version that we have not fully tested yet, you can get one from Git, but you would need to manually figure out the dependencies that are not included in the repository. E.g. you can try getting the new picotool from the VS Code extension, or check if Raspberry Pi maintainers have published a pre-built version.
Long-term, it looks like the packages used by the RP2040 VS Code extension are usable now, so we will eventually switch VisualGDB to download them just like it downloads the Arduino packages, so you won’t need wait for us to repackage anything.
