Section titled “v0.196.0 (August 24, 2026)”Title: Add Byron PBFT validation and improve CBOR list decoding
Date: August 24, 2026
Version: v0.196.0
This release adds Byron PBFT validation and allows CBOR decoding to read list headers that use longer-than-necessary fixed-length encodings.
💪 Improvements
Section titled “💪 Improvements”-
Added Byron PBFT validation: Both validation paths now check Byron headers and delegations, use genesis data to identify active delegates, apply the
22/100issuer window, and follow the2kactivation and replacement rules. Issuer parsing blocks replay, and proxy signature checks use the correct domain tags for light and heavy proxies. -
Improved CBOR list decoding: The decoder now reads list headers that use longer-than-necessary fixed-length encodings while preserving its fast path for canonical one-byte headers. Regression coverage protects both forms.
