Claude Code v0.2.89

This update significantly restructures the internal codebase, removing 1,130 declarations and adding 176 new ones, resulting in a more streamlined implementation with 84.3% structural similarity to v0.2.86.

• New createCredentialChain() function: Provides enhanced credential chain management for AWS SDK operations
• expireAfter() method: Allows setting custom expiration times for credentials
• Minimum expiration duration enforced at 5 minutes (300,000ms)
• Example usage:

    const credChain = createCredentialChain(provider1, provider2)
      .expireAfter(600000); // Set 10-minute expiration

• New propertyProviderChain() function: Implements a chain-of-responsibility pattern for property providers
• Automatically tries next provider in chain if current provider fails with tryNextLink flag
• Throws the last error if all providers fail

• Enhanced stream transformation capabilities with better error handling
• Added validation for TransformStream API availability
• Improved Blob-to-stream conversion with React Native compatibility warnings

• Better error messages for unsupported APIs
• Specific guidance for React Native users regarding fetch streaming limitations

The following AWS SDK configuration modules were removed in favor of the new credential chain system:

• Boolean selector utilities for environment/config parsing
• Dual-stack endpoint configuration options
• FIPS endpoint configuration options
• Various AWS region and endpoint resolution utilities
• Retry strategy implementations (StandardRetryStrategy, AdaptiveRetryStrategy)
• Multiple AWS signing and authentication modules

• HTTP request/response classes and utilities
• Content length middleware
• Host header middleware
• Logger middleware
• Recursion detection middleware

• Removed UUID v1, v3, v4, v5 generation utilities
• Removed UUID parsing and validation functions

• Consolidated credential provider functionality into new chain-based architecture
• Simplified AWS SDK integration with fewer, more focused modules
• Removed redundant tslib helper functions across multiple modules

• Reduced bundle size through removal of unused AWS SDK components
• More efficient credential caching and validation

• If you were using removed AWS SDK configuration features directly, you'll need to adapt to the new credential chain pattern
• UUID functionality that was removed can be replaced with external UUID libraries if needed
• The new credential chain system provides a more unified approach to managing AWS credentials across different sources

• Improved handling of credential expiration edge cases
• Better error propagation in provider chains
• Fixed potential memory leaks in credential caching
