All notable changes to BitRep will be documented in this file.

[0.4.0] - 2026-03-08

Changed

Removed deprecated reputation scoring system; migrated to canonical binary-attestation model.
Attestation model now reflects {issuer, subject, attestation_type, signature, timestamp, anchor}.
Removed weight, value, from_user, to_user, context, and mutual_validation fields from attestations.
Removed reputation_score from user identity model.
Replaced PageRank-based weighted reputation with direct binary attestation queries.
Replaced quadratic reputation-weighted governance voting with one-identity-one-vote.
Updated ZK proof to prove attestation-count threshold (not reputation score).
Removed reputation band privacy endpoint.
