## Telescope v2.0: A Major Leap Forward

Telescope v2.0 represents the most significant update to our blockchain code generation toolkit since its inception. Building on the foundation that already powers **Osmosis**, **dYdX**, and the **Cosmos Hub**, this release modernizes the entire codebase and introduces **InterchainJS** as the default signing client library.

With over **7.6 million total downloads** and **320,000 monthly installs**, Telescope continues to be the go-to solution for TypeScript blockchain development. Version 2.0 takes this further by providing enhanced type safety, improved multi-chain capabilities, and a more developer-friendly experience.

## 🚀 Major Changes in v2.0

### InterchainJS as Default

The biggest change in v2.0 is that **InterchainJS is now the default** instead of CosmJS. This migration brings significant improvements:

- **Better TypeScript support** with improved type safety
- **Enhanced multi-chain capabilities** for cross-chain applications
- **Modern signing patterns** with improved developer experience
- **Future-proof architecture** aligned with the latest Cosmos ecosystem standards

### Environment Preset Changes

The default environment preset has changed from `"default"` to `"v-next"`, enabling more modern code generation patterns that align with current best practices.

### Enhanced Default Setting

Version 2.0 enables several improvements by default:
- Improved interface generation patterns
- Prototypes setting enhanced
- Better client generation defaults
- Enabled helper functions by default

## 🔧 Configuration Changes

### New Defaults in v2.0

```typescript
// v2.0 defaults
const telescopeOptions = {
  env: "v-next",                    // Changed from "default"
  useInterchainJs: true,            // Changed from false
  
  // Enhanced interface support
  interfaces: {
    enabled: true,
    useGlobalDecoderRegistry: true, // Changed from false
    useUnionTypes: true,            // Changed from false
  },
  
  // Improved prototypes configuration
  prototypes: {
    methods: {
      fromJSON: false,              // Changed from true
      toJSON: false,                // Changed from true
      toSDK: false,                 // Changed from true
      fromSDK: false,               // Changed from true
      fromSDKJSON: false,           // Changed from true
    },
    enableRegistryLoader: false,    // Changed from true
    typingsFormat: {
      num64: "bigint",              // Changed from "long"
      useTelescopeGeneratedType: true, // New option
      setDefaultEnumToUnrecognized: true, // New behavior
    }
  },
  
  // Client generation defaults
  stargateClients: {
    enabled: false,                 // Changed from true
  },
  lcdClients: {
    enabled: false,                 // Changed from true
  },
  rpcClients: {
    enabled: false,                 // Changed from true
  },
  
  // Helper functions enabled by default
  helperFunctions: {
    enabled: true,                  // Changed from false
    useGlobalDecoderRegistry: true,
  }
};
```

## 🎯 What This Means for Developers

### Improved Type Safety

With InterchainJS as the default, developers get enhanced TypeScript support that catches more errors at compile time and provides better IDE integration.

### Modern Development Patterns

The `v-next` environment preset enables modern code generation patterns that align with current JavaScript and TypeScript best practices.

### Simplified Configuration

Many previously manual configurations are now enabled by default, reducing the setup complexity for new projects while maintaining full customization options for advanced use cases.

### Better Performance

The new defaults focus on generating leaner, more efficient code that performs better in production environments.

## 🔄 Migration Guide

### For Existing Projects

If you're upgrading from v1.x, the migration is straightforward:

1. **Update your package.json**:
   ```bash
   npm install @hyperweb/telescope@^2.0.0
   ```

2. **Review your configuration**: Most projects will benefit from the new defaults, but you can explicitly set options if you need the old behavior.

3. **Test your generated code**: The InterchainJS migration may require updates to your application code that uses the generated clients.

### Breaking Changes

While we've designed v2.0 to be as backward-compatible as possible, some breaking changes are necessary for the modernization:

- Default signing client library changed from CosmJS to InterchainJS
- Default environment preset changed to `v-next`
- Some method generation defaults have changed
- Number handling now defaults to `bigint` instead of `long`
