Realise the truth (2.12.x VS 2.13.0)...

Obviously, besides the bugs and glitches, the hottest issue here right now is the new NOD32 PCU, namely the 2.13.0. There are lot of threads started about it and one big misconception.

Well, people do not know the difference between versions (lines) 2.12.x and 2.13.0.

The first one, is the current line we (most of us) have on our machines. There are two common (latest) minor-sub-versions: 2.12.3 (paid) and 2.12.4 (trial). Considering the functionality, they are the same. Trial minor-sub-version, beside the paid one, has incremented number because in the trial 2.12.3 version was a bug. Thus, there is no PAID 2.12.4 version (and probably will never be)!!!

The latter (2.13.0), is highly awaited line that will be released somewhere in not so far future. It will have a few profound improvements*, as announced by Marcos. The notification bubble is one of them... ;-)

Let's wrap it up:
- 2.12.3 (paid) == 2.12.4 (trial).
- There is no new* feature in the 2.12.4 compared to 2.12.3. We wait for the successor.
- The anticipated version (PCU) is 2.13.0. Hurry up, ESET!

* "Automatic, fully controlled submission of suspicious files, detection of suspicious files run on system startup, the support for potentially dangerous applications in all modules, new EMON, an option to unregister DMON from the system, improved cleaning algorithm and some other minor improvements" ... "a bubble in the right-hand corner that replaces the pop-up window after an update." -Marcos
