Unblocked from FB... why?

[Haajee]

Long story short:

She blocked me because she thinks I did something to her. I'm completely innocent but some ppl will believe what they want to believe and never change their mind. She blocked me from FB for over 3 yrs and never once approached me to ask what happened.

Last night just randomly I looked thru my pics and came across one that she commented on and rather than her name be in black letters (Indicating a member who blocked me), her name was in the usual blue. I clicked it out of curiosity if it meant I'm unblocked or not and alas! Unblocked!!
Now here's my Q. Why? Change of heart? Has FB gone through another privacy setting thing and everyone who blocked us or who we blocked is now unblocked?

I have no plans to contact her because she requested that I never contact her or speak to her again. I didn't do anything to her but I'd like to know what this is all about.

Any help is greatly appreciated. Thanks guys!!

far as i know facebook didn't change, so i guess she just unblocked you.
