Version 1.6.1 is primarily a maintenance release, but does bring a handful of nice feature additions and enhancements. After a very successful 1.6.0 release, a series of bugs have been squashed and enhancements have been made that we wanted to roll out as a formal release. Updating from 1.6.0 is as easy as simply replacing a few files in your system directory. For a list of all changes please see the Change Log [1]. If you are currently running CodeIgniter please read the update instructions [2].
Happy Publishing!
