No matching function call for timer? I am using the Timer library here with the Adafruit feather m0: 
https://github.com/JChristensen/Timer 
https://playground.arduino.cc/code/timer 
I cannot figure out why I am getting the error: 

no matching function for call to 'Timer::every(int, void (&amp;)())' 

Here is that part of the code: 

void setup(){
      everyAlt = t.every(100, readAltimeter);
      everyLaunch = t.every(500, detectLaunch);
      t.oscillate(blueled, 500, HIGH);
    }


    void readAltimeter(){
      alts[altPlace] = bmp.readAltitude()-zeroAlt;
      altPlace++;
    }


    void detectLaunch(){
      tempSpeed = 0;
      int x = 0;
      while (x &lt; 5){
        tempSpeed += abs((alts[x]-alts[x+1])*10);
      }
      if (tempSpeed/5 &gt; 5){
        t.stop(everyLaunch);
      }
    }


I am pretty new to arduino so any help would be much appriciated!
Had the wrong version. Correct version downloaded from the current master: github.com/JChristensen/Timer
