[r287392]The watchdogd(8)daemon now supports a -x exit_timeout option to specify the timeoutperiod in seconds to leave in effect when the program exits. [r287080]4.2. Contributed Software A bug in libarchive(3)library which could report an error when handling a sparse file entry in a tarfile has been fixed by importing changeset bf4f6ec64e.

[r287737]5. Kernel This section covers changes to kernel configurations, system tuning, andsystem control parameters that are not otherwise categorized. The vt(4)terminal console driver now supports ALT_BREAK_TO_DEBUGGER and debug.kdb.alt_break_to_debuggersysctl variable when kernel debugger support (options KDB) is enabled. [r286742]The vt(4)terminal console driver now supports kern.vt.bell_enable sysctl variable toenable or disable terminal bell. The default is 1 (enabled).
