Release Notes - v0.183.0

v0.183.0 (June 12, 2026)

Title: Account state queries, era model cleanup, and safer pipeline validation

Date: June 12, 2026

Version: v0.183.0

Hi folks! Here’s what landed in v0.183.0.

This release adds the new Conway era GetAccountState query, clarifies that Dijkstra is the era while Leios is an overlay protocol introduced within Dijkstra era support, and fixes pipeline validation so unchecked blocks do not affect chain state when validation is enabled.

✨ What’s New

• Added the GetAccountState query for Conway account state: gOuroboros now returns treasury and reserves account state through GetAccountState, which unblocks workflows such as cardano-cli transaction build against gOuroboros based nodes instead of failing with an unsupported query. GetAccountState is a Conway era query, and requests on pre Conway chains now return a clear error instead of sending an unsupported query.

💪 Improvements

• Updated era lineage guidance: gOuroboros now treats Dijkstra as the era and Leios as an overlay protocol introduced within Dijkstra era support, so documentation and related guidance no longer present Leios as a standalone era.

• Fixed pipeline validation behavior: gOuroboros now stops unchecked blocks before they affect chain state when validation is enabled, and it returns a clear error instead.

📋 What You Need to Know

• Published the prior v0.182.0 release notes: the release history now includes the previous version page so the published notes remain current.
