Ubisoft Reflections was responsible for overhauling the driving mechanic. Ubisoft Montreal studied player feedback from the first game to assess what could be improved in Watch Dogs 2 and the setting was researched by making frequent trips to California. Cooperative multiplayer allows for competitive one-on-one combat and connecting with other players to neutralize a player who is causing havoc. There are multiple ways to complete missions, and each successful assignment increases the follower count of DedSec. Players control Marcus Holloway, a hacker who works with the hacking group DedSec to take down the city's advanced surveillance system known as ctOS. Set within a fictionalized version of the San Francisco Bay Area, the game is played from a third-person perspective and its open world is navigated on-foot or by vehicle. It was released for the PlayStation 4, Xbox One and Microsoft Windows in November 2016, and Stadia in December 2020. It is the sequel to 2014's Watch Dogs and the second installment in the Watch Dogs series. Read-only class properties are declared with the readonly context-sensitive keyword in a typed property.Watch Dogs 2 (stylized as WATCH_DOGS 2) is a 2016 action-adventure game developed by Ubisoft Montreal and published by Ubisoft. A class property declared read-only is only allowed to be initialized once, and further changes to the property is not allowed. PHP 8.1 brings support for read-only class properties. However, it is a stepping stone for concurrent PHP frameworks to effectively manage their execution stack, and allow simultaneous execution. Fiber by itself does not allow simultaneous execution of multiple Fibers or the main thread and a Fiber. It is important the concurrent execution does not mean simultaneous execution. The main program can resume the Fiber from the point it was suspended. With Fibers, the code block within the Fiber can suspend the code block and return any data back to the main program. Fibers are created, started, suspended, and terminated by the program itself, and allows fine control of the main program execution and the Fiber execution. Threads are scheduled by the operating system, and does not guarantee when and at which point the threads are paused and resumed. In essence, a Fiber is a code block that maintains its own stack (variables and state), that can be started, suspended, or terminated cooperatively by the main code and the Fiber.įibers are similar to threads in a computer program. Fibersįibers is a new feature in PHP 8.1 that brings lightweight and controlled concurrency to PHP. magic numbers) to store and work with parameters, Enums make the application code more readability, and avoids unexpected application state. In contrast to using special strings or numbers internally (i.e. In PHP, these suits can be enumerated with an Enum: enum Suit pick_card(Suit::Clubs) A deck of playing cards has four suits, and they are fixed: Clubs, Diamonds, Hearts, and Spades. An Enumeration, or an Enum for short, is an enumerated type that has a fixed number of possible values.Ī popular analogy for an Enum is suits in a deck of playing cards. Further, it adds Fibers, which makes a significant step towards concurrent PHP applications, which sets PHP beyond the traditional request-response pattern. PHP 8.1 adds features such as Enums, which was one of the most frequent and anticipated features to land in PHP. It also deprecates a handful of features, which might add some friction when upgrading legacy PHP applications to PHP 8.1. Some of the highlights of PHP 8.1 include support for Enums, Fibers, never return type, Intersection Types, readonly properties, and first-class callable syntax. They will be making the minor releases in PHP 8.1 series until PHP 8.1 reaches its end-of-life at the end of year 2024. Release managers for PHP 8.1 are Joe Watkins, Ben Ramsey, and Patrick Allaert. It also adds more features that encourages defensive programming. PHP 8.1 is a continuation of PHP's progress in providing a type system improvements. PHP 8.1 is a major new version to PHP, which brings several new features, quality-of-life improvements, and attempts to prepare PHP to iron out some of its legacy features by deprecating and restricting certain undesired functionality.
