o OpenSSH has been upgraded to 7.1p2. o A bug in bsnmpd(1) causing breakage on platforms with strict alignment requirements has been fixed. o A leak of routing table allocations occurring when shutting down VNET- enabled jails has been fixed. o The tty(4) layer now prohibits opening the callout device when the corresponding callin device (in disguise as the console device) is already opened. o Corruption of coredumps due to procstat notes changing size during coredump generation have been fixed. o A leap-seconds file for ntpd(8) now is installed by default and ntpd.conf(5) as well as the corresponding rc(8) files have been updated accordingly. Additionally, support for updating the leap- seconds file via periodic(8) has been added (defaulting to off). o The UEFI ZFS loader has been updated to support the latest ZFS Boot Environment (BE) loader menu features. o The initialization of random(9) has been adjusted so it is usable earlier. This fixes the "random device not loaded; using insecure entropy" message output during boot on some systems. o The ixgbe(4) driver has been updated to the Intel FreeBSD Networking Group version 3.1.13-k and support for X552 and X550T was added. Also, SFP module insertion post boot, the VF handling of VLANs in the Amazon Cloud, GBIC and PHY power setup (correcting link detected on X540-AT2 after a previous boot to Linux) and incorrect reporting of unsupported flow control auto negotiation have been fixed. Additionally, the flow control and link speed negotiation defaults now may be be configured via the hw.ix.flow_control and hw.ix.advertise_speed loader tunables respectively, with the previously available hw.ix.enable_aim now only setting the default for adaptive interrupt moderation and which can be overridden on a per-interface basis during runtime via the enable_aim SYSCTL. Note, however, that Amazon EC2 Enhanced Networking later turned out to actually still not operate properly with these changes. o The sfxge(4) driver has been enhanced with a SIOCGI2C IOCTL, allowing to query SFP+/QSFP+ module information via `ifconfig -v`. o The UEFI boot loader received several improvements: /boot/config and /boot.config files now are adhered to, multi device boot support works and command line argument parsing has been added.
