v01-00

This is a first stable release of EDM4hep with backwards compatibility guarantees for subsequent versions. Files written with this version will remain readable with upcoming versions of EDM4hep1. We do not make any forward compatibility guarantees, i.e. files written with a more recent version of EDM4hep will most likely not be readable with a less recent version.

There are two versions that are important for EDM4hep;

  • The EDM4hep version (i.e. vXX-YY) which signifies changes in the API of EDM4hep
  • The EDM4hep schema version (currently 6) which signifies changes to the EDM4hep schema.

While the "API version" of EDM4hep might change without changes to the schema version this is not true vice versa.

  • 2025-11-10 Thomas Madlener (PR#459)

    • Make the test environments for python based tests more focused on the current build

  1. In fact we currently guarantee backwards (read) compatibility down to files written with v00-99-02, except for the edm4hep::GeneratorEventParameters type, which is stable only since v00-99-03). Note that some of the changes from v00-99-02 imply that not all of the information that is stored in the files is actually also still available in memory. ↩
