The 2015 amendments to the Federal Rules of Civil Procedure took effect on December 1, 2015.

Some of the amendments apply even to cases that were filed prior to that date.

The authors of the Federal Civil Rules Handbook, 2016 edition, William M. Janssen and Steven Baicker-McKee discuss the treatise and the new 2015 amendments.

William Janssen also has a series of articles on Federal Rules of Civil Procedure on the Legal Solutions Blog.
