# v1.3.21

> Enterprise v1.3.21 changelog - 2026-04-30

<Update label="Bifrost Enterprise" description="v1.3.21">
  ## Changelog

  This patch release fixes a governance gossip reliability issue where peers could prematurely expire a node's usage snapshot during idle periods, and completes the Go 1.26.2 build toolchain rollout across all environment images.

  ## ✨ Features

  * **Governance Heartbeat Gossip** - Governance broadcast manager now refreshes unchanged usage snapshots every 10s, preventing peers from expiring this node's state via the 30s stale-node TTL when budgets and rate limits are idle
  * **Reliable Governance Broadcast Path** - Governance gossip now uses the reliable `Broadcast` path instead of `BroadcastNoACK`, so oversized payloads can fall back to ACK/retry rather than being silently dropped

  ## 🐞 Fixed

  * **Stale Governance State on Idle Clusters** - Fixed a window where a quiet node's budget/rate-limit snapshot could be evicted from peers during periods of unchanged usage, causing transient gaps in cluster-wide governance enforcement

  ## 🛠️ Build

  * **Go 1.26.2 Across All Env Images** - Bumped the Go toolchain in the root `Makefile`, the `examples/plugins/hello-world` Makefile, and every `infra/envs/*/Dockerfile` to Go 1.26.2, completing the toolchain alignment started in v1.3.20

  ## 📀 Base OSS version
