EOEPCA+ System - Release 2.0

Release 2.0

Release Date: 05 February 2026
https://eoepca.readthedocs.io/projects/deploy/en/eoepca-2.0/

Release 2.0 is the first formal release of EOEPCA+, since the last EOEPCA release 1.4 - representing a full refresh of the EOEPCA+ building blocks. EOEPCA+ 2.0 provides many new capabilities, with improved stability - ready for production deployment.

The release is additionally accompanied by supporting materials - including, for each Building Block:

• Notebooks - that provide a quick demonstration of core capabilities
• Tutorials - that showcase the building block and its basic installation in a generic reproducible environment

The following table summarises the evolution that EOEPCA+ Release 2.0 represents compared to EOEPCA 1.4.

Note that all EOEPCA+ 2.0 building blocks are integrated with the authentication and authorization approach of the IAM building block
