feat(http): add automatic rate limit handling with smartrequest

- Migrated HTTP client to @push.rocks/smartrequest for robust rate limiting
- Automatic retry with exponential backoff (1s, 2s, 4s) on HTTP 429
- Respects Retry-After headers from server
- Improved error handling and network resilience
- Updated documentation with rate limit handling examples

 # Changelog
 
+## 2025-07-29 - 4.3.0 - feat(http)
+Enhanced HTTP client with automatic rate limit handling
+
+- Added @push.rocks/smartrequest dependency for robust HTTP handling
+- Implemented automatic retry with exponential backoff for rate-limited requests
+- Built-in handling of HTTP 429 responses with intelligent waiting
+- Respects Retry-After headers when provided by the server
+- Maximum of 3 retry attempts with configurable backoff (1s, 2s, 4s)
+- Improved error handling and network resilience
+- Updated readme documentation with automatic rate limit handling examples
+
+## 2025-07-27 - 4.2.1 - fix(tests)
+Fix test compatibility with breaking changes from v4.0.0
+
+- Updated all tests to handle new API structure where methods return objects
+- Fixed destructuring for getAccounts() which now returns { accounts, sessionData? }
+- Ensures all 83 tests pass successfully with the stateless architecture
+
+## 2025-07-27 - 4.2.0 - feat(core)
+Switch to native fetch API for all HTTP requests
+
+- Replaced @push.rocks/smartrequest with native fetch API throughout the codebase
+- Updated HTTP client to use fetch with proper error handling
+- Updated attachment upload/download methods to use fetch
+- Updated export download method to use fetch  
+- Updated sandbox user creation to use fetch
+- Removed smartrequest dependency from package.json and plugins
+- Improved error messages with HTTP status codes
+
+## 2025-07-26 - 4.1.3 - fix(export)
+Fix PDF statement download to use direct content endpoint
+
+- Changed `downloadContent()` method to use the `/content` endpoint directly for PDF statements
+- Removed unnecessary attachment lookup step that was causing issues
+- Simplified the download process for customer statement exports
+
+## 2025-07-25 - 4.1.1 - fix(httpclient)
+Fix query parameter handling for smartrequest compatibility
+
+- Changed query parameter handling to pass objects directly instead of URLSearchParams
+- Removed URLSearchParams usage and string conversion
+- Now passes queryParams as an object to smartrequest which handles URL encoding internally
+
+## 2025-07-25 - 4.1.0 - feat(transactions)
+Enhanced transaction pagination support with full control over historical data retrieval
+
+- Added full `IBunqPaginationOptions` support to `getTransactions()` method
+- Now supports `older_id` for paginating backwards through historical transactions
+- Supports custom `count` parameter (defaults to 200)
+- Maintains backward compatibility - passing a number is still treated as `newer_id`
+- Only includes pagination parameters that are explicitly set (not false/undefined)
+- Added `example.pagination.ts` demonstrating various pagination patterns
+
+This enhancement allows banking applications to properly fetch and paginate through historical transaction data using both `newer_id` and `older_id` parameters.
+
 ## 2025-07-25 - 4.0.0 - BREAKING CHANGE(core)
 Complete stateless architecture - consumers now have full control over session persistence
