Release 2.0.0-RC2 supporting PHP 7.0-7.3 syntax

on PHP Packagist

The Phan 2.x releases support analysis of php 7.0-7.3, and can be executed with php 7.1+.

New features(Analysis):

• Support analysis of PHP 7.4's short arrow function syntax (fn ($arg) => expr) (#2714)
  (requires php-ast 1.0.2dev or newer)

  Note that the polyfill does not yet support this syntax.

• Infer the return types of PHP 7.4's magic methods __serialize() and __unserialize(). (#2755)
  Improve analysis of return types of other magic methods such as __sleep().

• Support more of PHP 7.4's function signatures (e.g. WeakReference) (#2756)

• Improve detection of unused variables inside of loops/branches.

Plugins:

• Detect some new php 7.3 functions (array_key_first, etc.) in UseReturnValuePlugin.
• Don't emit a PhanNativePHPSyntaxCheckPlugin error in InvokePHPNativeSyntaxCheckPlugin due to a shebang before declare(strict_types=1)
• Fix edge cases running PhanNativePHPSyntaxCheckPlugin on Windows (in language server/daemon mode)

Bug fixes:

• Analyze the remaining expressions in a statement after emitting PhanTraitParentReference (#2750)
• Don't emit PhanUndeclaredVariable within a closure if a use variable was undefined outside of it. (#2716)
