The reality is that the interface is not changed much and where it has, I preferred the former version. I can see few other benefits, especially when most "new" functions (and there are not many substantial ones) can be obtained from simple free programs that I already have and I could probably do without them anyway. Also, I have noticed that throttling has gone. Also my total download speed seems to have been capped at 64kbs and I cannot see why or how to change this. And my floater has gone - maybe I need to look for it but why should I? It will cost me ~£8 to upgrade and I don't think it is worth it this time. I can see that Version 4 remains in the Applications folder. Hopefully it will still work and I can simply bin version 5. I have been with this program since very early days as a fully paid up customer but I think I've paid enough. So, I can't recommend this version to present users of version 4 unless it changes substantially with updates (note updates, not upgrades) as it is too similar to the last version. And by the way, any bugs removed does not warrant a fee as they shouldn't have been there in the first place. Maybe new users will find it useful but for me the program is getting tired and I will look elsewhere.
