Added Intel Atom C3000 pci(4) ids. -
Added port protection support to switch(4). Domain membership is checked for unicast, flooded (broadcast) and local (host-network-bound, e.g. trunk) traffic. -
Introduced malloc_conceal(3) and calloc_conceal(3), which return memory in pages marked MAP_CONCEAL and call freezero() on free(). -

Fixed integer overflow with an excessively large number of kqueue(2) events. -
Added support for more Intel 300 Series PCH to ichiic(4). -
Moved bgpd(8) pfkey socket to the parent process. The refreshing of the keys is done whenever the session state changes to IDLE or ACTIVE, which should behave better when reloading configs with auth changes. -
Fixed a bug in pkg_info(1) -S where version elements were ignored. - -
Ensured mcx(4) completion queues are always rearmed to prevent rx or tx completion stalling. - -
Adjusted unwind(8) to try to resolve the DNSSEC trust anchor only if we have a validating resolver context. -
To restore lockf(3) deadlock detection, introduced a list for all pending blocked locks to be scanned before waiting on a blocking lock in order to determine whether sleeping would cause a deadlock. -

Fixed a logic error when configuring the alc(4) driver to use msi. - -
Fixed the case where switchd(8) does not save a copy of a packet needing forwarding. -
Added support for the EFI Random Number Generator Protocol, using it to XOR random data into the buffer we feed the kernel for amd64. - -
Relaxed a check in knote(9) to prevent a panic without KERNEL_LOCK(). -
Began to assume eDP is present on port A when there is no VBT, making inteldrm(4) work on a Gemini Lake system (HP Stream Laptop 14-cb1XX) where finding the VBT fails. -
Improved the interaction among efifb(4), inteldrm(4) and radeondrm(4) for a serial console by introducing a 'primary' device, the one set up and used by firmware. This should help X to work correctly out of the box with multiple cards or with a serial console. -
Added mcx(4) driver for Mellanox ConnectX-4 (and later) Ethernet controllers. - -
Began to allow panes to be empty in tmux(1), allowing output to be piped to them with split-window or display-message -I. -

Increased datasize and maxproc for the pbuild class in login.conf(5). - -

Protected tun(4) wakeup with KERNEL_LOCK, rather than NET_LOCK. - -
Pulled cdfs and cdrom production into the full ramdisk build for i386. -
Added a 'set_rate' method to the envy(4) codec API, allowing card-specific codec initialization code called when the sample rate is changed.

Enabled mvmdio(4) and mvneta(4) on arm64. -
Enabled EnvyHT-specific sample rates (above 96kHz) on the host controller for envy(4) devices. -

Added the pci(4) product id for the VMware nvme(4) interface. -
Added support for ccp(4) at acpi(4). -

Removed file name and line number output from witness(4), along with the wrapper for mutexes. -
Added -no-clear variants of copy-selection and copy-pipe to tmux(1) which do not clear the selection after copying. -
Checked for linkstate instead of IF_STA_POINTTOPOINT for originating router LSAs for P2P interfaces in ospfd(8), making 'passive' work on P2P interfaces. - -
Modified vmm(4) to flush guest TLB entries if the guest disables paging. -
Began to change only the clock frequency and skip setting voltage on arm64 systems supporting DVFS which do not expose a regulator. -
Added support for official Linux device tree bindings and the 'stub' clocks handling CPU clock frequency on the Hi3670. -
Stopped prompting for disks that do not contain a root partition during upgrades. This defaults to the correct disk when full disk encryption is in use, and will be useful for future unattended upgrades. - -
Set vlan(4) to use if_vinput instead of if_input, bypassing ifiqs and improving vlan input speeds. -
Added if_vinput so pseudo (ethernet) interfaces can bypass ifiqs, running interface input handlers directly rather than queuing the packets for a nettq to run and improving performance. -
Disabled mobileip(4). -
Added support for rxprio to gre(4). -
Implemented the roff(7) .break request, preventing infinite loops. -
Built clang(1) on powerpc. -

Added stdio pledge(2) to nl(1) after opening a file but before doing operations. -
Completed conversion of rdsetroot(8) to -lelf on alpha. -
Adjusted dma-range bufcache to 80% from 20%, to learn the downsides of this change based on user reports. -
Avoided an underflow in the rip6 delivered counter in netstat(1). -
Fixed netstat(1) statistics so 'netstat -s -f inet6 -p rip6' correctly copies out rip6counters, not ip6counters. - -
Adapted radeon_detach_kms() to struct drm_device being split from drm softc. Avoids uvm_fault() when firmware is missing and radeondrm(4) is forcibly detached. -
Added a subsystem lock for vfs_lockf.c, allowing calling lf_advlock() and lf_purgelocks() without the kernel lock. -
Implemented factored-out txprio and rxprio checks. -
Implemented rxprio in mpw(4), mpe(4) and mpip(4). Added rxprio support to etherip(4) and bpe(4). - -

Modified pfctl(8) to always check for namespace collisions on table commands. -
Fixed pfctl(8) table definition parsing as unprivileged user, printing a brief notice if -v was given to help find duplicate definitions by hand. -

Released OpenSSH 8.0. -
Switched powerpc to big PIC to allow clang(1) to build libc++abi and libc++. - -
Used txprio to control the use of exp as a priority field for mpw(4), mpip(4) and mpe(4). Intermediate LSPs can use the exp field to manage prioritization of encapsulated traffic. -

Introduced 'pfctl -FR' to reset pfctl(8) settings to defaults. -
Removed old -vlan and -vlandev code from ifconfig(8), using these instead as aliases for -vnetid and -parent. - -
Added basic support to ifconfig(8) to display xfp and qsfp+ information. -
Implemented SIOCGIFSFFPAGE to allow ifconfig(8) to get transceiver information from myx(4) devices. -
