========================================
1. Backward Incompatible Changes
========================================
- Core:
  . 'void' can no longer be used as the name of a class, interface, or trait.
    This applies to declarations, class_alias() and use statements.

========================================
2. New Features
========================================
- Core
  . Added void return type, which requires that a function not return a value.
    (RFC: https://wiki.php.net/rfc/void_return_type)

5. Changed Functions
========================================
- get_headers() has an extra parameter which allows passing a custom stream
  context.
- The first $varname argument for getenv() is no longer mandatory, the
  current environment variables will be returned as an associative array
  when omitted.
- long2ip() accepts integer as parameter now
- pg_last_notice() accepts optional long parameter to specify operation.
  PGSQL_NOTICE_LAST - Get last notice (Default)
  PGSQL_NOTICE_ALL - Get all stored notices
  PGSQL_NOTICE_CLEAR - Remove all stored notices
  It returns empty string or array on successful PGSQL_NOTICE_LAST/ALL calls.
  It returned FALSE for empty notice previously.
- pg_fetch_all() accepts 2nd optional result type parameter like
  pg_fetch_row().
- pg_select() accepts 4th optional result type parameter like pg_fetch_row().
- parse_url() is more restrictive now and supports RFC3986.
