Release Notes - v0.193.3

v0.193.3 (August 17, 2026)

Title: Refresh dependencies and mainnet bootstrap handling

Date: August 17, 2026

Version: v0.193.3

This release refreshes core dependencies, removes the emurgo bootstrap peer from Cardano mainnet, and hardens Leios genesis parsing for Shelley and Conway genesis data.

💪 Improvements

• Updated core dependencies: github.com/blinklabs-io/ouroboros-mock moved from v0.15.1 to v0.16.0, golang.org/x/crypto moved from v0.54.0 to v0.55.0, and github.com/stretchr/testify moved from v1.11.1 to v1.12.0, including the examples/ping module.

• Removed the emurgo bootstrap peer from Cardano mainnet: the default mainnet peer set no longer includes it.

• Fixed Leios genesis extra config parsing: Shelley and Conway genesis handling now rejects unsafe extra config values before initialization.

🙏 Thank You
