There have been some changes in the coefficient calculation as noticed by Ed and peeotreck.
First of all the bonus point were tweaked. Second, the calculation for national associations that have hosted a final tournament in the reference period was changed.
In the case of an association that has hosted a UEFA EURO or FIFA World Cup final tournament during one of the reference periods as mentioned under Annex B.1.2 and therefore has no points from the respective qualifying competition, the points earned in the most recent qualifying competition in which the association has taken part are used.
in the old regulations it was:
In the case of an association that hosted a UEFA EURO or FIFA World Cup final tournament and therefore has no points from the tournament qualifying competition, the points earned in the qualifying competition in the previous cycle are used to avoid a distorted calculation based on results in the final tournament only, supplemented by bonus points.
I asked UEFA about these changes and here's the answer:
The new bonus points enter into force from now on (parallel to the regulations’ entry into force on 1 Jan 2014) and are applied for the first time to the WC 2014 qualifiers, but according to general UEFA policy we will not change any coefficients retroactively.
The UEFA coefficient ranking will be published on 24 Jan following the decision by the UEFA Executive Committee on the UEFA EURO 2016 qualifying draw procedure and seeding system.
So, if I get this right, these changes will be applied only to the results of the 2014 FIFA World Cup qualifying competition. The teams involved in the play-offs lose some points, but the pots remain the same.
