I would doubt if Glickmans methodology has changed much.
More likely Chess.com staff may have updated their interpretation of and how they operate the software.
Overall in my view a step in the right direction.
>:)
PS; down with Glickman, ECF & FIDE rule.
I think the current system is a modified version of the Glicko, not sure about the details... perhaps someone from the staff could explain ?
lol ECF! Nothing chess.com ever does to their ratings can ever come close to that debacle! 
The whole thing is wrong. Maybe it works at professional level to decide who gets a shot at the title, or how to segregate the GM's. For the standard Chess playing community it's just numbers to give you something to aim at improving. If you put any stock in it though it must be totally deflating to see yourself go through a bad patch. It's just totally unnecessary.
For a period of 18 months (until recently) I was undefeated, wasn't working off a rating, I played whoever came at me and won. Some good players, average players, poor players, none of that was important to me, the only thing of significance was knowing I was playing well. I was happy with that. If my opponent was good it made me feel good to win. I don't need a rating to tell me how good I'm playing.
When my streak came to an end I lost 1, drew 2, won 3, then lost and drew again, one more defeat (last night, ouch!) and I'm still waiting on my next victory. To put a number on that is moot because I know I'm not playing at my best. What good does it do me to see it printed as a number that means absolutely nothing to me?
RD sucks.
It punishes players for playing frequently because when they win they receive hardly any points and can't progress on with their rating.
Yet if you play infrequently your rating is more likely to be volatile and move more wildly.
This surely is a flaw to the system.
I think you should get rid of Glicko altogether.
I don't really see the major flaw with ELO anyway. So what if someone doesn't play for a while and gets rusty. Their rating will soon adjust if their playing strength has diminished.
