The International Earth rotation Service (IERS) has just published bulletin C 51, announcing that *no* leap second will be introduced at the end of June 2016: ftp://hpiers.obspm.fr/iers/bul/bulc/bulletinc.dat The IERS now also makes a leap second file available for use with NTP: https://hpiers.obspm.fr/iers/bul/bulc/ntp/leap-seconds.list This new file has the expiration date set to 28 December 2016, so users who have configured ntpd to use the leap second file should upgrade their local copy of the file. The leap second file does not only announce leap seconds, it also provides ntpd and thus the OS kernel with the current TAI/UTC offset, which is helpful for applications working with TAI.
