EEP 0: Index of Erlang Enhancement Proposals (EEPs)


The EEP contains the index of all Erlang Enhancement Proposals, known as EEPs. EEP numbers are assigned by the EEP Editor, and once assigned are never changed. The history of the EEP texts represent their historical record.

The textual format for an EEP is described in EEP 1, and EEP 33 is a template.

EEPs are discussed on the mailing list and accepted or rejected by the OTP team.
