 ### Changes
 
+- Add max bytes contraints in simple solo sequnecer [#3312](https://github.com/evstack/ev-node/pull/3312)
+- Add support for otlp in execution/grpc. [#3300](https://github.com/evstack/ev-node/pull/3300)
 - Optimization of mutex usage in cache for reaper [#3286](https://github.com/evstack/ev-node/pull/3286)
+- Add Unix domain socket support for gRPC execution endpoints via `unix:///path/to/socket` [#3297](https://github.com/evstack/ev-node/pull/3297)
+- **BREAKING:** (execution/grpc)
+  - Move execution service where it belongs in execution/grpc. [#3302](https://github.com/evstack/ev-node/pull/3302)
+  - Replace legacy gRPC execution `txs` payload fields with `tx_batch` so clients and servers use contiguous transaction buffers [#3297](https://github.com/evstack/ev-node/pull/3297)
+- Optimize metadata writes by making it async in cache store [#3298](https://github.com/evstack/ev-node/pull/3298)
+- Reduce tx cache retention to avoid OOM under (really) heavy tx load [#3299](https://github.com/evstack/ev-node/pull/3299)

 # gRPC Single Sequencer App
 
-This application runs a Evolve node with a single sequencer that connects to a remote execution client via gRPC. It allows you to use any execution layer that implements the Evolve execution gRPC interface.
+This application runs an Evolve node with a single sequencer that connects to an execution client via gRPC. It allows you to use any execution layer that implements the Evolve execution gRPC interface.
 
 ## Overview
 
 The gRPC single sequencer app provides:
 
-- A Evolve consensus node with single sequencer
-- Connection to remote execution clients via gRPC
+- An Evolve consensus node with single sequencer
+- Connection to execution clients via TCP or Unix domain socket gRPC
 - Full data availability layer integration
 - P2P networking capabilities
