I have a 2010 iMac and I installed Mac OS 10.10 public beta last summer, but I haven't received any updates since. My exact version right now is OS X 10.10 (14A379b).
Does anyone know what should i do to get the latest system updates?

Update incrementally to Beta 3. And you will get immediate update to 7th beta (So they've done combo update from 3 to 7 - nothing more is known)
This is what is shown in App Store on Beta 3.
After update:
Go to the Purchased page and click UPDATE there.

in my guess, your beta may be expired, so the solution would be a final yosemite install from app store.
