========================================
New Features
========================================

- Core:
  . Added support for union types.
    RFC: https://wiki.php.net/rfc/union_types_v2
  . Added WeakMap.
    RFC: https://wiki.php.net/rfc/weak_maps
  . Added ValueError class.
  . Any number of function parameters may now be replaced by a variadic
    argument, as long as the types are compatible. For example, the following
    code is now allowed:

Code (PHP8)
        class A {
            public function method(int $many, string $parameters, $here) {}
        }
        class B extends A {
            public function method(...$everything) {}
        }


  . "static" (as in "late static binding") can now be used as a return type:

Code (PHP8)
        class Test {
            public function create(): static {
                return new static();
            }
        }


    RFC: https://wiki.php.net/rfc/static_return_type
  . It is now possible to fetch the class name of an object using
    `$object::class`. The result is the same as `get_class($object)`.
    RFC: https://wiki.php.net/rfc/class_name_literal_on_object
  . New and instanceof can now be used with arbitrary expressions, using
    `new (expression)(...$args)` and `$obj instanceof (expression)`.
    RFC: https://wiki.php.net/rfc/variable_syntax_tweaks
  . Some consistency fixes to variable syntax have been applied, for example
    writing `Foo::BAR::$baz` is now allowed.
    RFC: https://wiki.php.net/rfc/variable_syntax_tweaks
  . Added Stringable interface, which is automatically implemented if a class
    defines a __toString() method.
    RFC: https://wiki.php.net/rfc/stringable
  . Traits can now define abstract private methods.
    RFC: https://wiki.php.net/rfc/abstract_trait_method_validation
  . `throw` can now be used as an expression.
    RFC: https://wiki.php.net/rfc/throw_expression
  . An optional trailing comma is now allowed in parameter lists.
    RFC: https://wiki.php.net/rfc/trailing_comma_in_parameter_list
  . It is now possible to write `catch (Exception)` to catch an exception
    without storing it in a variable.
    RFC: https://wiki.php.net/rfc/non-capturing_catches
  . Added support for mixed type
    RFC: https://wiki.php.net/rfc/mixed_type_v2
  . Added support for Attributes
    RFC: https://wiki.php.net/rfc/attributes_v2
    RFC: https://wiki.php.net/rfc/attribute_amendments
    RFC: https://wiki.php.net/rfc/shorter_attribute_syntax
  . Added support for constructor property promotion (declaring properties in
    the constructor signature).
    RFC: https://wiki.php.net/rfc/constructor_promotion
  . Added support for `match` expression.
    RFC: https://wiki.php.net/rfc/match_expression_v2
  . Private methods declared on a parent class no longer enforce any
    inheritance rules on the methods of a child class. (with the exception of
    final private constructors)
    RFC: https://wiki.php.net/rfc/inheritance_private_methods
  . Added support for nullsafe operator (`?->`).
    RFC: https://wiki.php.net/rfc/nullsafe_operator
  . Added support for named arguments.
    RFC: https://wiki.php.net/rfc/named_params

- Date:
  . Added DateTime::createFromInterface() and
    DateTimeImmutable::createFromInterface().
  . Added the DateTime format specifier "p" which is the same as "P" but
    returning "Z" for UTC.

- Dom:
  . Introduce DOMParentNode and DOMChildNode with new traversal and
    manipulation APIs.
    RFC: https://wiki.php.net/rfc/dom_living_standard_api

- Enchant:
  . enchant_dict_add()
  . enchant_dict_is_added()
  . LIBENCHANT_VERSION macro

- FPM:
  . Added a new option pm.status_listen that allows getting status from
    different endpoint (e.g. port or UDS file) which is useful for getting
    status when all children are busy with serving long running requests.

- Hash:
  . HashContext objects can now be serialized.

- Opcache:
  . If the opcache.record_warnings ini setting is enabled, opcache will record
    compile-time warnings and replay them on the next include, even if it is
    served from cache.

- OpenSSL:
  . Added Cryptographic Message Syntax (CMS) (RFC 5652) support composed of
    functions for encryption, decryption, signing, verifying and reading. The
    API is similar to the API for PKCS #7 functions with an addition of new
    encoding constants: OPENSSL_ENCODING_DER, OPENSSL_ENCODING_SMIME and
    OPENSSL_ENCODING_PEM.

- Standard:
  . printf() and friends now support the %h and %H format specifiers. These
    are the same as %g and %G, but always use "." as the decimal separator,
    rather than determining it through the LC_NUMERIC locale.
  . printf() and friends now support using "*" as width or precision, in which
    case the width/precision is passed as an argument to printf. This also
    allows using precision -1 with %g, %G, %h and %H. For example, the following
    code can be used to reproduce PHP's default floating point formatting:

Code (PHP8)
        printf("%.*H", (int) ini_get("precision"), $float);
        printf("%.*H", (int) ini_get("serialize_precision"), $float);


  . proc_open() now supports pseudo-terminal (PTY) descriptors. The following
    attaches stdin, stdout and stderr to the same PTY:

Code (PHP8)
        $proc = proc_open($command, [['pty'], ['pty'], ['pty']], $pipes);


  . proc_open() now supports socket pair descriptors. The following attaches
    a distinct socket pair to stdin, stdout and stderr:

Code (PHP8)
        $proc = proc_open(
            $command, [['socket'], ['socket'], ['socket']], $pipes);


    Unlike pipes, sockets do not suffer from blocking I/O issues on Windows.
    However, not all programs may work correctly with stdio sockets.
  . Sorting functions are now stable, which means that equal-comparing elements
    will retain their original order.
    RFC: https://wiki.php.net/rfc/stable_sorting

- Zip:
  . Extension updated to version 1.19.0
  . New ZipArchive::lastId property to get index value of last added entry.
  . Error can be checked after an archive is closed using ZipArchive::status,
    ZipArchive::statusSys properties or ZipArchive::getStatusString() method.
  . The remove_path option of ZipArchive::addGlob() and ::addPattern() is now
    treated as arbitrary string prefix (for consistency with the add_path
    option), whereas formerly it was treated as directory name.
  . Optional compression / encryption features are listed in phpinfo.

UPGRADING
- Core:
  . Following the hash comment operator # immediately with an opening bracket
    is not supported as a comment anymore since this syntax is now used for
    attributes.
    RFC: https://wiki.php.net/rfc/shorter_attribute_syntax_change
  . Compile time fatal error "Only variables can be passed by reference" has
    been delayed until runtime and converted to "Argument cannot be passed by
    reference" exception.
  . Some "Only variables should be passed by reference" notices have been
    converted to "Argument cannot be passed by reference" exception.
  . Added support for Attributes
    RFC: https://wiki.php.net/rfc/attributes_v2
    RFC: https://wiki.php.net/rfc/attribute_amendments
    RFC: https://wiki.php.net/rfc/shorter_attribute_syntax
    RFC: https://wiki.php.net/rfc/shorter_attribute_syntax_change

- OpenSSL:
  . openssl_seal() and openssl_open() now require $method to be passed, as the
    previous default of "RC4" is considered insecure.

- pgsql:
  . The deprecated pg_connect() syntax using multiple parameters instead of a
    connection string is no longer supported.
  . The deprecated pg_lo_import() and pg_lo_export() signature that passes the
    connection as the last argument is no longer supported. The connection
    should be passed as first argument instead.

- Standard:
  . Calling crypt() without an explicit salt is no longer supported. If you
    would like to produce a strong hash with an auto-generated salt, use
    password_hash() instead.
  . array_diff(), array_intersect() and their variations can now be used with
    a single array as argument. This means that usages like the following are
    now possible:

Code (PHP8)
        // OK even if $excludes is empty.
        array_diff($array, ...$excludes);
        // OK even if $arrays only contains a single array.
        array_intersect(...$arrays);

    (cmb)

https://raw.githubusercontent.com/php/php-src/php-8.0.0rc1/NEWS


UPGRADING
- Core:
  . call_user_func_array() array keys will now be interpreted as parameter names,  
    instead of being silently ignored. 

- IMAP: 
  . The unused default_host argument of imap_headerinfo() has been removed.
  . The imap_header() function which is an alias of imap_headerinfo() has been removed. 

- ODBC:
  . odbc_connect() no longer reuses persistent connections.
  . The unused flags parameter of odbc_exec() has been removed. 

- MySQLi / PDO MySQL:
  . When mysqlnd is not used (which is the default and recommended option), 
    the minimum supported libmysqlclient version is now 5.5. 

- PGSQL / PDO PGSQL:
  . pg_fetch_all() will now return an empty array instead of false for result
    sets with zero rows. 
  . Function aliases in the pgsql extension have been deprecated.

- SPL: 
  . SplFixedArray is now an IteratorAggregate and not an Iterator.
    SplFixedArray::rewind(), ::current(), ::key(), ::next(), and ::valid()
    have been removed. In their place, SplFixedArray::getIterator() has been
    added. Any code which uses explicit iteration over SplFixedArray must now
    obtain an Iterator through SplFixedArray::getIterator(). This means that
    SplFixedArray is now safe to use in nested loops. 

- Standard:
  . The $flag parameter of ob_implicit_flush() was changed to accept bool
    values rather than int. 

- Sysvsem: 
  . The $auto_release parameter of sem_get() was changed to accept bool values 
    rather than int. 

- Zip:
  . Extension updated to version 1.19.1

- Zlib:
  . zlib.output_compression is no longer automatically disabled for
    Content-Type: image/*.
