Release Notes - v0.46.1

v0.46.1 (May 14, 2026)

Title: Safer startup recovery, genesis governance loading, and leader-scheduling fixes

Date: May 14, 2026

Version: v0.46.1

Hi folks! Here’s what we shipped in v0.46.1.

✨ What’s New

Added load Conway genesis governance at startup: Preview testnet nodes now load initial DReps and delegations from Conway genesis, which gives governance aware networks the right starting state from first startup.

💪 Improvements

Improved honor peer sharing settings more accurately: Nodes now follow peer sharing settings more consistently, which makes peer discovery behavior easier to control.
Refined surface unreadable governance proposals more clearly: Governance stability checks now report unreadable governance proposals through clearer signals, which makes investigation easier.
Enhanced keep devnet configurator changes in sync: Devnet validation now rebuilds the configurator image when setup scripts change, which keeps test environments aligned with the latest startup behavior.
Updated clarify mempool and UTxO RPC package guidance: Embedded package guidance now explains mempool and UTxO RPC behavior more clearly for library users.
Modernized publish the v0.46.0 release notes page: The release history now includes a dedicated v0.46.0 page, which keeps recent release guidance easier to find.
Refreshed remove self references from release pages: Release pages now focus more cleanly on shipped behavior, which makes recent changes easier to scan.

🔧 Fixes

Fixed stop block producers when genesis snapshot capture fails: Block producing nodes now fail fast when the initial genesis snapshot cannot be captured, which avoids unsafe startup with incomplete leader data.
Corrected recover from missing primary chain ancestors at startup: Startup recovery now rolls back to a valid common ancestor when the stored ledger tip is no longer on the primary chain, which helps nodes resume cleanly after fork changes.
Strengthened return setup errors instead of crashing: Startup now returns actionable errors when required services are missing, which makes failures easier to diagnose without abrupt crashes.
Stabilized use schedule-aware epoch lookup for leader checks: Leader scheduling now uses the correct epoch for each slot across era boundaries, which avoids missed or incorrect production decisions.
Hardened restore pool state details more reliably: Pool state parsing now finds the correct active pool map and deposit data more reliably, which keeps pool information accurate.
Repaired skip offset indexing for Byron boundary blocks: Block indexing now skips Byron epoch boundary blocks that contain no transactions, which avoids false parsing during startup and backfill.
Secured keep UTxO RPC TLS certificates in memory: UTxO RPC TLS startup now loads certificates into memory before serving, which makes secure startup more reliable.
Advanced wait for fresh hard fork evaluation after rollback: Rollback handling now waits for stale hard fork stability work to clear before trusting new results, which keeps era readiness signals safer.

📋 What You Need to Know

Clarified preview governance bootstrap starts in the right state: Preview testnet nodes now begin with Conway governance delegations and DRep data loaded from genesis.
Highlighted startup recovery is safer for producers and recovering nodes: Block producers stop on missing genesis snapshots, and nodes can rewind to a safe ancestor when stored chain state no longer matches the primary chain.
Emphasized leader and pool decisions now follow chain data more accurately: Leader scheduling respects real epoch boundaries, and pool state restoration keeps operator data more dependable.
Summarized secure and diagnosable startup behavior improved: TLS serving, dependency checks, peer sharing behavior, and governance observability now fail or report issues more cleanly.
