on Cloud Manager I've seen that all environments are still on 2023.12 version, but on the release notes documentation was already announced the 2024.01 version from January 25, 2024.
In Software Distribution the last sdk version is v2023.12.
Latest SDK release is now available in Cloud Manager for upgrade. You should be able to do it now as well as you should be able to download from Software Distribution.
In all environments now, I'm seeing a notice to upgrade to the latest 2024.02 version that came out this morning, and software distribution is also carrying the latest SDK.
