# Dapr v1.18.4

> Orchestration & Management · 2026-09-09

A workflow-heavy maintenance release corrects reliability, state-management, signing, and pub/sub delivery defects. It also changes binary gRPC metadata filtering for output bindings, with no newly announced operator configuration requirements.

## Action needed
- **[breaking]** Binary gRPC metadata propagation in `InvokeBinding`, removed
  - Binary gRPC metadata with keys ending in `-bin` is no longer copied from incoming gRPC calls into output binding component metadata for `InvokeBinding`.

## Other recorded changes
- 18 (defect_corrected 18)
