  • 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).
