Dear MOSIP Community,

We’re excited to announce the release **[eSignet v2.0.0](https://github.com/mosip/esignet/tree/v2.0.0 "https://github.com/mosip/esignet/tree/v2.0.0")** — a major milestone that marks the migration of eSignet’s core engine from Java to Go, built on the [ThunderID engine](https://github.com/thunder-id/thunderid/tree/v1.0.1 "https://github.com/thunder-id/thunderid/tree/v1.0.1"). This release carries forward [eSignet (Java) v1.8.0’s](https://github.com/mosip/esignet/tree/v1.8.0) core authentication capabilities to the new Go-based engine.

**Major Highlights**

1. **Go-Based Core Engine** — rebuilt on Go, using the [ThunderID engine](https://github.com/thunder-id/thunderid/tree/v1.0.1).

2. **Flow-Graph Driven Authentication** — login and consent screens now render from a declarative flow graph.

3. **Feature Parity with eSignet v1.8.0** — authentication flows and standards compliance are unchanged for end users and integrators.

4. **Performance and Scalability** — the Go-based engine delivers better throughput than the Java version at similar or lower resource usage.

5. **New eSignet (Go) Documentation** — a complete documentation set covering architecture, the developer guide, and integration is now available.

6. **Reference Plugin Implementations Retained** — Mock, MOSIP, and Sunbird plugins all carry forward unchanged.

⚠ **Note:** This release includes a couple of breaking changes for anyone upgrading from the Java version — please review the **[Breaking Changes](https://docs.esignet.io/home/esignet-2.x/roadmap-and-releases/versions/v2.0.0#breaking-changes)** section of the release notes before you upgrade.

To explore all the features, breaking changes, and known issues in detail, please refer to the full [release notes](https://docs.esignet.io/home/esignet-2.x/roadmap-and-releases/versions/v2.0.0).
