Release Notes - v0.191.3

v0.191.3 (August 5, 2026)

Title: Strengthen ledger validation and request handling

Date: August 5, 2026

Version: v0.191.3

This release strengthens address validation, preserves original CBOR bytes across round-trips, makes consensus validation TPraos aware, and keeps block requests aligned with the caller context.

💪 Improvements

• Fixed Bech32 address decoding: invalid Bech32 addresses now fail validation instead of falling back to Base58.

• Strengthened address payload decoding: trailing bytes now fail validation instead of passing through.

• Restored CBOR round-tripping: Datum and SetType preserve their original bytes when marshaled.

• Improved consensus validation: generic header validation and block building now follow TPraos rules.

• Refined leiosfetch request handling: block requests now respect the caller context, and timeouts no longer stop processing.

• Enforced block verification limits: VerifyBlock now applies execution and size limits across the full block.

🙏 Thank You
