Lets pack() and unpack() take < and > byte order markers on the f and d float codes, matching the integer syntax added in PHP 8.6.

Makes closures cheaper by inferring static when $this is unused and caching stateless closures, though only the caching part was merged.

Adds grapheme_strrev() to intl, which reverses a string by grapheme cluster so emoji and combined characters stay intact.

Adds the form feed character (\f) to the default set of characters that trim(), ltrim() and rtrim() strip.

Adds a TLS session class and stream context options so clients and servers can save, store and resume TLS sessions.

Adds mysqli::quote_string(), which escapes a string and wraps it in single quotes, like PDO::quote(), to close a double-quote injection hole.

Adds exception and silent modes for stream errors, with structured StreamError objects and a StreamErrorCode enum you can inspect.

Adds Perl-style < and > byte order modifiers to pack() and unpack(), so signed integers can be little-endian or big-endian.

Adds a clamp() function that returns a value if it falls between min and max, or the nearest bound if it doesn't.

Adds ? and ... placeholders to function calls, so passing only some arguments returns a closure that takes the rest later.

Adds ReflectionProperty::isReadable() and isWritable() so you can check whether a property can be read or written from a given scope.
