Ok folks, I'm finally ready to bite the bullet and upgrade my apps.

Here's a question though. If you use the cmdline.txt file to put the commands in, for example -instances_per_device 2, do you still have to change the <count> tag to 0.5 in your app_info.xml file?

Yes.

Plus -instances_per_device 2 is no longer in play with the newer apps.

Yes.

So, is 0.5 in the appinfo enough to make the app run two instances? No need at all for -instances_per_device ?

I still use both settings because of bug hunting.
If you dont use instances_per_device its not mentioned in stderr.txt how many instances are running.

Yeah, now that you mentioned it, I took a look in one stderr produced by the new app, and sure enough it doesn't say how many instances it was running. It did run 2 with only count 0.5 in the appinfo, but you would never know it from the stderr file.

Tested by setting -instances_per_device 2, in the cmdline file, and as you say, now it shows how many instances the app is running.

Thanks Mike, that was very good to be told. I'm sure I would have asked otherwise why I no longer can see the number of instances in the stderr file. Saved me some thinking there :-)
