This time last year OSI recommended that the CRA:

…exclude all activities prior to commercial deployment of the software and … clearly ensure that responsibility for CE marks does not rest with any actor who is not a direct commercial beneficiary of deployment.

That recommendation has been accepted and implemented, and the OSI is very grateful to the various experts who took the time to listen.

My ELI5 version is: The European government were making a rule where software makers can be punished for not following European standards and need a special mark of compliance. Open source organizations argued that the standards shouldn't be held against any group until a software is sold, and volunteer/non-profit groups shouldn't have to follow the standard. The Parliament listened and implemented this change to the draft rule.
