The Twilio Helper Library for PHP has been released, offering new features and improved functionality based on developer feedback. The library now uses modern PHP language features and provides better paging and namespace support. It introduces the concepts of Resource Context and Resource Instance to improve network efficiency. The library is available in two lines: mainline with stable releases and edge with new features in Developer Preview or Beta. The new version expects required parameters as individual arguments, making the code easier to read and catch missing parameters. A Getting Started Guide and Quickstart are available to help users get started with the new library.
