v3.3.0 — hybrids3 v0.2.0 (presigned PUT URLs) Adds upload presigning. ?method=PUT (or boto3 put_object) returns a signed PUT URL; default remains GET. Method is bound into the SigV4 canonical request — GET-signed URLs cannot PUT, vice versa. Public buckets still require a signed URL for PUT. See CHANGELOG.md for full details.
