“Developers Options” menu is missing in Jelly Bean 4.2

After updated to Jelly Bean 4.2, you will find “Developers Options”   missing.

It is there, just 4 taps away

1. Goto  “About phone” (or tablet) 
2. Tap the "Build number" (the last item) 4 times slowly
3. On each tap, it will remind you how many "click" away from being a "developer"
4. At the end, it will told you "You are a developer now"

The "Developer options" will show up again in the "Settings" just above  “About phone” (or tablet)
