Spark Tokens Client: Spark vs spark

Hi all,

Can anyone tell me what the difference is for the spark token clients? Specifically Spark vrs spark… (I can pretty much guess what spark_ide, and IFTTT are already…)

{
“token”: “token_num”,
“expires_at”: “2015-03-19T21:18:44.482Z”,
“client”: “spark”
},
{
“token”: “token_num”,
“expires_at”: “2015-04-15T15:33:54.207Z”,
“client”: “Spark”
}

Is that just indicating it’s my most recent token? (Which would be awesome if so!)
