Is it necessary to upgrade from 1.3 to 1.4?

[freakarus]

Good Day,

I am using Spybot 1.3 since a long time and I am really satisfied with it :)
As well as every one of my friends whom I recomended or installed this software.

I recantly discoverd that there is the new release 1.4.
Unfortunately I couldn't find any informations about the differences among the 2 releases. Therefore my question should I upgrade and why?

Thanks

You should upgrade to Spybot 1.4,unless you're running Windows 95.

The major reason for upgrading to Spybot S&D 1.4 is that 1.3 can't use over half the detections included in the current updates. Since the core technology to support Services and WinLogon entries was added to 1.4, there is no way for 1.3 to take advantage of these.

Basically, there are so many existing issues with 1.3 and it's so out of date, the only reason NOT to update to 1.4 is if the PC is Windows 95. There's also the TeaTimer pop-up dialog display issue mentioned by md usa spybot fan above, but that only matters if you use TeaTimer Resident and can be fixed via the link he included.
