mte-relay-browser-public-client 4.5.3 is a patch release of the v4 web
client. In Firefox, every earlier v4 client sent request bodies as empty. Chrome
and Edge were not affected. The relay needs no change, and 4.5.3 works with
every v4 server.
MTE Relay 5.0.5 is a patch release of MTE Relay Server and MTE API Relay. It covers everything since 5.0.1: both servers on the Azure Marketplace, a preset first configuration for the control plane, and security fixes. v5 clients and configuration work unchanged.
MTE Relay 5.0.1 is a patch release of MTE Relay Server and MTE API Relay. It puts both v5 servers on the AWS Marketplace, lets the MTE API Relay outbound pool grow with demand, and closes two control plane secret exposures. v5 clients and configuration work unchanged.
v4.8.0 adds configurable CORS request header allowances so browser clients can send application headers unencrypted. Applies to MRS and MAR. Fully backwards compatible, no client changes required.
MTE Relay v5 is a new major version with a new wire protocol, and on the same hardware it outperforms v4 across the board: up to 37% more requests per second, about 90% less memory per relay, and up to 39% lower latency.
v4.7.0 adds standard forwarding headers and fixes a health check regression. Applies to MRS and MAR. Fully backwards compatible, no client changes required.
v4.6 builds on the v4.5 Go rewrite with improved cloud marketplace support, AKS marketplace packaging, and outbound proxy fixes. Application traffic flow is unchanged.
MTE Relay Server v4.5 is a ground-up rewrite of the relay in Go. Releases through v4.4 ran on Node.js; v4.5 reimplements the entire proxy as a single, statically compiled Go service.
The rewrite delivers lower memory use, faster request handling, and a smaller, hardened container image, while keeping the MTE/MKE encryption and Kyber pairing protocol intact so existing clients keep working. It also introduces a new multi-tenant configuration model that becomes the preferred way to run the relay.
MTE Relay Server v4.4 adds more flexible logging controls, better request-level observability, and improved upstream connection handling.
This release is aimed at making production behavior easier to tune and diagnose without changing application traffic flow.
MTE Relay Server v4.3 adds clearer startup warnings for non-production trial builds.
This update focuses on safer deployment behavior and better visibility into unsupported runtime configurations.
