prEN IEC 63584:2024

This specification defines version 2.0.1 of OCPP.
After the release of OCPP 2.0, some issues were found in OCPP 2.0. Some of these issues could not be fixed issuing errata to the specification text only, as has been done with OCPP 1.6, but required changes to the protocol’s machine-readable schema definition files that cannot be backward compatible.
To prevent confusion in the market and possible interoperability issues in the field, OCA has decided to name this version: 2.0.1. OCPP 2.0.1 contains fixes for all the known issues, to date, not only the fixes to the messages.
This version replaces OCPP 2.0. OCA advises implementers of OCPP to no longer implement OCPP 2.0 and only use version 2.0.1 going forward.
Any mentions of "OCPP 2.0" refers to revision 2.0.1 unless specifically stated otherwise.
