Status of Elsevier Boycott
(converted from a comment on request).

I don't think much has changed about pricing, but Elsevier has made open access all the content of their journals in mathematics after a 48 month embargo (source). This was a very appreciated move: mathematicians often rely on old articles for their research, so 4 years isn't too long to wait (for some), for this discipline. It is also a shrewd move from Elsevier, since it pleases their audience but doesn't cut into their main source of income, which are yearly subscription access deals with university libraries.

Maybe this will encourage academics from other fields to consider a similar protest to obtain the same boon...
