Release Notes - v0.178.0

v0.178.0 (May 26, 2026)

Title: Migrate example applications, expand Cardano aware CBOR diagnostics, and publish a public diagnostics API

Date: May 26, 2026

Version: v0.178.0

Hi folks! Here’s what landed between v0.171.0 and v0.178.0.

✨ What’s New

• Expanded first party example coverage: The repository now ships first party example applications for block fetch, chain sync, chain tip, peer sharing, ping, state query, tx monitor, and tx submission.

• Updated example application layout: The examples now live under examples/ as standalone modules, and local runs should start from that location instead of the earlier cmd/ path.

• Enhanced Cardano aware diagnostic formatting: Diagnostic formatting is now available for transactions, blocks, Plutus data, and native scripts.

• Refined annotated diagnostic output: Diagnostic output can include Cardano labels and human readable address annotations.

• Introduced public diagnostics access: A public diagnostics API now covers generic CBOR plus Cardano transactions and blocks, with parse trees, offsets, warnings, and statistics.

📋 What You Need to Know

• Clarified documentation guidance: Documentation and local workflows should no longer describe these examples as coming from the retired starter kit repository, and should use the final examples/ path.

🙏 Thank You
