IRI1.4.2.4 is better in confirmation time than IRI1.5.0

[Tobo01]

I was using the desk light wallet to make transactions in last two days. I used field.carriota.com to connect to my light wallet. Some times it showed the IRI is 1.5.0 and some times it is 1.4.2.4 on the upper left part of my wallet.

It seems that iri1.4.2.4 could get faster confirmation than iri1.5.0. Whenever it showed iri1.4.2.4, I could get the confirmations under 5 minutes without reattaching for each transaction. But whenever it showed iri1.5.0, it took at least 5 reattachings for a transaction to get confirmed.
