Ever wanted to search for N=2 SUSY but experienced troubles with the special meaning of the equal sign? You can now type N=2 in the search box and find all papers with N=2 in the title or abstract. In SPIRES syntax you'd have to use quotation marks, e.g. find t "N=2". Omitting the quotation marks in a SPIRES-style search would remove the equal sign as well, giving you papers with N2 in the title.
In addition, linking to the new pdglive via PDG identifiers like S032:DESIG=1 has been implemented. To make this possible the old spires search variant "field=value", e.g."author=dumbledore", had to be disabled. Since our log files show that this syntax is only used very rarely nowadays this is a small price to pay for these new search options. But if you were using searches like find a witten and date=2012 try find a witten and date 2012 instead.
