## Overview

Para v2.0 represents a significant evolution in our SDK architecture and developer experience. This release introduces streamlined authentication flows, improved component structure, and enhanced wallet management while maintaining backward compatibility where possible.

## New Features

*We'll keep adding features as they get rolled out, check back in here for the latest!*

* **Guest Mode**: Let users ["Continue as Guest"](/v2/react/guides/customization/guest-mode) and provision them a wallet to experience your app before they sign up.

## Key Improvements

### Simplified Authentication

The v2.0 release dramatically simplifies authentication flows by consolidating multiple methods into single, intuitive interfaces:

* **Unified Entry Point**: The new `signUpOrLogIn` method replaces separate user existence checks, login initiation, and user creation methods
* **Standardized Auth State System**: A consistent state machine approach for tracking authentication progress
* **Enhanced OAuth Flow**: Streamlined third-party authentication with platforms like Google, Apple, and Discord
* **Improved Social Login**: Simplified Farcaster and Telegram login experiences

### Enhanced React Integration

React developers will find substantial improvements to the integration experience:

* **Single Provider Pattern**: The `ParaProvider` now handles all configuration needs
* **Built-in Modal**: Modal functionality is now included within the provider by default
* **React Query Integration**: Leverages the power of TanStack Query for predictable state management
* **Powerful Hooks**: New purpose-built hooks that encapsulate common authentication and wallet operations

### Streamlined Wallet Management

Wallet operations have been refined for better developer experience:

* **Simplified Pregen Wallet API**: More intuitive API for creating and managing pregenerated wallets
* **Improved Wallet Type System**: Better TypeScript support with string union types replacing enums
* **Consistent Identity Representation**: New auth object pattern for representing user identities

### Cancellable Operations

Long-running operations now support cancellation, improving the user experience:

* **Interactive Polling**: Long-running operations support cancellation callbacks
* **Progress Events**: Operations can emit progress events for better UI feedback
* **Error Recovery**: Improved error handling for interrupted operations

## Developer Experience Improvements

Beyond the technical enhancements, Para v2.0 brings significant developer experience improvements:

* **Object Parameter Pattern**: All methods now use a consistent object parameter pattern, improving code readability and extensibility
* **Reduced Boilerplate**: Common authentication flows require significantly less code
* **Better TypeScript Support**: Enhanced type definitions and more precise typing
* **Simplified Configuration**: External wallet configuration is now consolidated in one place

## Looking Forward

Para v2.0 represents our commitment to continuously improving the developer experience. We welcome your feedback on these changes.
