A decider combinator tests conditions on its inputs and outputs signals when they hold. Since 2.0 one combinator takes several conditions joined by and/or, can read the red and green wires apart, and can have several outputs.	`Decider combinator 2.0Decider combinator 2.0Decider combinator 2.0`	Dev blog
2.0 added a selector combinator, which picks signals out of its input: the signal at a given rank when sorted by value, the count of input signals, a random input signal at a set interval, or an item's stack size. 2.1 added a time mode that outputs the game tick, the time of day and the length of a day, and lets the index mode select the N highest or lowest signals.	`The Selector combinatorThe Selector combinatorThe Selector combinatorThe Selector combinator`	Dev blog
