• Removed message_id and message_uid from smtpd(8). It now has an evpid associated to each delivery message, the evpid is an u_int64_t where the upper 32 bits are the msgid, and the 32 bits are the envelope unique identifier for that message.
• Make sure iswctype(3) wcwidth() return -1 if the character is not printable. Adapt file(1) to this behaviour.
• Removed dead assignments from ix(4) IPv6 Multicast Listener Discovery.
• Prevent all kernels disk(9) subroutines from modifying flags used by the buffer cache.
• Silence daily(8) errors in the temporary directory cleanup process.
• Converted the kernel Makefiles to autogenerate dependencies during compilation using the -MD option to cc(1), with -MP, -MT, and -MF where needed, converting “make depend” to a no-op. This increases parallelism when using “make -j” and keeps the dependencies up to date with each compilation automatically.
• Implemented -MP, -MT and -MF options in gcc(1) so all platforms can support so-called “advanced automatic dependency generation”.
• Added fsqueue_message_create(), fsqueue_message_commit() fsqueue_envelope_create() and fsqueue_message_purge() to new smtpd(8) queue API and removed queue_hash().

• Fixed READ/WRITE confusion in bnx(4).
• Added support for per-rthread base-offset for the %fs selector on amd64. Added pcb_fsbase to the PCB for tracking what the value for the thread is, and ci_cur_fsbase to struct cpu_info for tracking the CPU’s current value for FS.base, then on return to user-space, skip the setting if the CPU has the right value already. Non-threaded processes without TLS leave FS.base zero, which can be conveniently optimized: setting %fs zeros FS.base for fewer cycles than wrmsr.
• Replaced NULL by 0 in sparc64 console initialization.
• Modified ix(4), em(4) interrupt handler so it only processes the rings once rather than looping over them until it runs out of work to do.

• In video(4) and uvideo(4), added support for VIDIOC_S_PARM and VIDIOC_G_PARM, ioctls used for setting and getting the frame interval.
• Make uvideo(4) print the supported frame intervals when printing the frame descriptor.
• Prevent uvideo(4) from changing the format group’s default frame when configuring the device, and from using the default frame as the current frame: because the format group ‘frame_cur’ handles it.
• Prevent uvideo(4) from trying to align its array of frame descriptors with the frame descriptor bFrameIndex field. The first valid frame in the array is at index 0, not 1.
