# v2.0.0-Beta.1

**Release Number:** v2.0.0-Beta.1\
**Release Date:** 26th Aug, 2026

## Overview

[eSignet v2.0.0-Beta.1](https://github.com/mosip/esignet/tree/v2.0.0-beta.1) marks the migration of eSignet's core authentication engine from Java to Go, built on the [Thunder ID engine](https://github.com/thunder-id).

This is a migration release: the eSignet user interface and feature set carry over unchanged, and this beta is at full feature parity with [eSignet (Java) v1.8.0](https://github.com/mosip/esignet/tree/v1.8.0), unless explicitly called out as out of scope below. No end-user-facing behavior has changed as part of this migration; what's changed is the engine running underneath.

## Major Highlights

### Go-Based Core Engine

eSignet's authentication engine has been rebuilt on **Go**, using the [**Thunder ID engine**](https://github.com/thunder-id) — a Go-based identity provider engine from WSO2. This is the foundational change behind this release, and everything else in this beta builds on it.

### Feature Parity with eSignet v1.8.0

All eSignet features present in the latest [Java release (**v1.8.0**)](https://github.com/mosip/esignet/tree/v1.8.0) are carried forward in this Go-based beta at full parity, except where explicitly listed as out of scope below. The UI, authentication flows, and standards compliance are unchanged for end users and integrators.

## Out of Scope

The following are **not supported** in this beta release:

* **WLA (Wallet-based Login Authentication)** login is not supported in this release.
* **Client management endpoint support for title and subtitle fields** during relying party (RP) onboarding is not supported in this release.
* **Database support is limited to PostgreSQL only** in this release; no other database backends are supported at this time.
* **This beta does not include the eSignet Signup module.** eKYC and Identity Assurance 1.0 capabilities remain on the Java-based Signup module for now and have not yet been migrated to Go.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.esignet.io/home/esignet-2.0.0/roadmap-and-releases/versions/v2.0.0-beta.1.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
