  • Several performance improvements in the engine, streams API and some Windows specific optimizations.
  • PDO_MySQL now uses buffered queries by default and emulates prepared statements to bypass limitations of MySQL's prepared statement API.
  • Many improvements and enhancements to the filter and zip extensions.
  • Memory limit is now always enabled, this includes Windows builds, with a default limit of 128 megabytes.
  • Added several performance optimizations using faster Win32 APIs (this change means that PHP no longer supports Windows 98).
  • FastCGI speed optimized build of PHP for Windows made available for downloading.
