  • Function array dereferencing has been added, e.g. foo()[0].
  • Closures now support $this.
  • <?= is now always available, regardless of the short_open_tag php.ini option.
  • Class member access on instantiation has been added, e.g. (new Foo)->bar().
  • Class::{expr}() syntax is now supported.
  • Binary number format has been added, e.g. 0b001001101.
  • Improved parse error messages and improved incompatible arguments warnings.
  • The session extension can now track the upload progress of files.
  • Built-in development web server in CLI mode.
