On May 7, the New York state legislature passed A9407, which extends the petitioning period for primary petitions from 37 days to 42 days. However, the bill only applies to 2014. The bill says that the such petitions can start to circulate on May 29, instead of June 3. The bill had been introduced on April 25. Governor Andrew Cuomo signed it on May 10.
The reason for the bill is that one of the Jewish holidays falls during the normal petitioning period. See this story. Thanks to Rick Hasen for the link.
