# multi Version: 1.6.0
Updated from 1.5.0
# multi Version: 1.7.0 (Taking multi-tasking to the next level)
Updated from 1.6.0 to 1.7.0
Modified: multi.intergration.lanesManager.lua
It is now in a stable and simple state Works with the latest lanes version! Tested with version 3.11 I cannot promise that everything will work with eariler versions. Future versions are good though.
Example Usage:
```lua
local GLOBAL,lthread=require("multi.intergration.lanesManager").init()
require("multi.alarm")
require("multi.threading")
multi:newAlarm(2):OnRing(function(self)
GLOBAL["NumOfCores"]=lthread.getCores()
end)
multi:newAlarm(7):OnRing(function(self)
GLOBAL["AnotherTest"]=true
end)
multi:newAlarm(13):OnRing(function(self)
GLOBAL["FinalTest"]=true
end)
multi:newSystemThread("test",function() -- spawns a thread in another lua process
require("multi.all") -- now you can do all of your coding with the multi library! You could even spawn more threads from here with the intergration. You would need to require the interaction again though
print("Waiting for variable: NumOfCores")
print("Got it: ",lthread.waitFor("NumOfCores"))
lthread.hold(function()
return GLOBAL["AnotherTest"] -- note this would hold the entire lthread. Spawn a coroutine thread using multi:newThread() or multi:newThreaded...
end)
print("Holding works!")
multi:newThread("tests",function()
thread.hold(function()
return GLOBAL["FinalTest"] -- note this will hold the entire lthread. As seen with the TLoop constantly going!
end)
print("Final test works!")
os.exit()
end)
local a=0
multi:newTLoop(function()
a=a+1
print(a)
end,.5)
multi:mainloop()
end)
multi:mainloop()
```
Onec I am happy with the intergration and feel it is ready I will document it better

Updated from 1.4.1
Updated from 1.4.1 to 1.5.0
Added:
- An easy way to manage timeouts
- Small bug fixes
1.4.1 - First Public release of the library
IMPORTANT:
Every update I make aims to make things simpler more efficent and just better, but a lot of old code, which can be really big, uses a lot of older features. I know the pain of having to rewrite everything. My promise to my library users is that I will always have backwards support for older features! New ways may exist that are quicker and eaiser, but the old features/methods will be supported.
