January 2026 upgrade

From the 5th of January to the 15th of January there will be a major upgrade of the data catalog infrastructure (SciCat - https://discovery.psi.ch and https://dacat.psi.ch)

During this period, data archiving and retrieval will not be possible.

Required changes

After the upgrade, a few changes will be required:

CLI changes

If you are using pmodules, no changes are required, otherwise:

1. please download the latest released CLI version (>=v3.0.0) by following the download instructions.
2. Modify your ingestion scripts, following the v3 instructions;
3. or download the backwards compatible scripts (linux only). Please note these scripts will later be discontinued (~ Q2 2026).

API changes

Some APIs have been updated. This affects you only if you interact directly with the SciCat APIs.

1. You can already find and compare the new API specifications from our QA environment.
2. Authorization update: API authorization now requires passing your token in the Authorization header, prefixed with Bearer, i.e. Bearer <MY_TOKEN>.
3. Login endpoint: API login is now available at /auth/login rather than users/login.
