  <li>Various kernel improvements:
    <ul>
+   <li>Added support for the Rockchip RK3568 processor.
+   <li>Implemented the <a
+         href="https://man.openbsd.org/waitid.2">waitid(2)</a> system call
+         which is now part of POSIX and used by Mozilla.
+   <li>Introduced <a
+         href="https://man.openbsd.org/clockintr.9">clockintr(9)</a>, a
+         machine-independent clock interrupt controller. Switched all
+         architectures to use this new kernel subsystem.
+   <li>Introduced a new kern.autoconf_serial <a
+         href="https://man.openbsd.org/sysctl.8">sysctl(8)</a> that can be used
+         by userland to monitor state changes of the kernel device tree.
+   <li>Fixed <a href="https://man.openbsd.org/pmap.9">pmap(9)</a> bugs
+         involving entering an executable mapping for a page before
+         synchronizing the data and instruction cache on arm64 and riscv64.
+   <li>Add detection for Spectre-BHB Branch History Injection
+         vulnerability related CLRBHB, ECBHB and CSV2_3/HCXT feature bits.
+   <li>Add <a
+         href="https://man.openbsd.org/getnsecruntime.9">getnsecruntime(9)</a>
+         to the kernel timecounting API. Together with getbinruntime(), it
+         provides a fast, monotonic clock that only advances while the system
+         is not suspended.
+   <li>Prevent detatching ("bioctl -d detach") of a boot volume on a RAID managed by <a
+         href="https://man.openbsd.org/bioctl.8">bioctl(8)</a>.
+   <li>Added WTRAPPED option for <a
+         href="https://man.openbsd.org/waitid.2">waitid(2)</a> to control
+         whether CLD_TRAPPED state changes, i.e., ptrace(2) on a process, are reported.
    <li>On arm64, avoid usin 1GB mappings for the identity map in the
          early kernel bootstrap phase and when booting the secondary CPUs. This
          avoids accidentally mapping memory regions that should not be mapped
          (i.e. secure memory) as all mapped memory can be accessed
          speculatively.
    <li>Added arm64 detection of EPAN feature bit. Enhanced Privileged Access Never
          (EPAN) allows Privileged Access Never to be used with Execute-only mappings.
    <li>Removed copystr(9) from public API.
    <li>Made the USB ports work after a suspend/resume cycle on the x13s.
-   <li>Set the arm64 default for the machdep.lidaction <a
+   <li>On arm64, add a machdep.lidaction <a
-         href="https://man.openbsd.org/sysctl.8">sysctl(8)</a> to 1, making the
+         href="https://man.openbsd.org/sysctl.8">sysctl(8)</a> for <a
+         href="https://man.openbsd.org/aplsmc.4">aplsmc(4)</a> Apple Silicon
+         laptops.<br>
+         The arm64 default for the machdep.lidaction is 1, making the
          system suspend when the lid is closed. <a
          href="https://man.openbsd.org/aplsmc.4">aplsmc(4)</a> provides support
          for the lid position sensor.
+   <li>Disable the screen backlight with <a
+         href="https://man.openbsd.org/aplsmc.4">aplsmc(4)</a> on Apple Silicon
+         laptops when the lid is closed.
    <li>Changed arm64 suspend idle loop from WFE to WFI, avoiding spurious
          wakeups while other CPUs are still active.
    <li>Added cursor back tab support to <a

          DTIOCARGS to get the type of probe arguments.
    <li>Added a priority queue to <a
          href="https://man.openbsd.org/clockintr.9">clockintr(9)</a>.

+         IPI counters where the event counted occurs across all CPUs in the
+         system.
+   <li>Moved <a href="https://man.openbsd.org/pf.4">pf(4)</a> purge

  <li>VMM/VMD improvements
    <ul>
+         <li>Updated <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> to
+                 allow guests to read MSR_HWCR and MSR_PSTATEDEF, which is necessary to
+                 determine the TSC frequency on AMD families 17h and 19h.
+         <li>Allocated reference for vm and vcpu SLISTs in <a
+                 href="https://man.openbsd.org/vmm.4">vmm(4)</a>, keeping vmm from

+         <li>Set <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> RAX guest
+                 register state based on VMCB.
+         <li>Removed locking in <a
+                 href="https://man.openbsd.org/vmm.4">vmm(4)</a> vmm_intr_pending,
+                 reducing slowdowns due to requests for a lock held while the VM is

+         <li>Increased speed of delivery of interrupts to a running vcpu in <a
+                 href="https://man.openbsd.org/vmm.4">vmm(4)</a>.
+         <li>Made <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> treat vcpu

  <li>Various new userland features:
    <ul>
+   <li>Added <a href="https://man.openbsd.org/kdump.1">kdump(1)</a>
+         argument support for msyscall, pledge, unveil, __realpath, ypconnect
+         and __tmpfd.
    <li>Added <a

          syscall address
    </ul>
  <li>Various bugfixes and tweaks in userland:
    <ul>
+   <li>The libc functions that use the zoneinfo database to convert
+         time between different timezones allowed the TY environment variable
+         to point to any file on the system to be reas as zoneinfo file.  This
+         was restricted to paths starting with /usr/share/zoneinfo in the TZ
+         environement variable.  Reject other absolute paths in TZ. The
+         assumption is that zoneinfo files under /usr/share/zoneinfo are
+         trustworthy, but
+   <li>Made <a href="https://man.openbsd.org/ldomctl.8">ldomctl(8)</a>
+         accept more descriptive name-based paths in addition to number-based
+         paths in <a
+         href="https://man.openbsd.org/ldom.conf.5">ldom.conf(5)</a>.
+   <li>Dropped support for $rc_exec in <a
+         href="https://man.openbsd.org/rc.subr.8">rc.subr(8)</a>. The rc_exec
+         function should be used instead.
+   <li>Excluded /tmp/*.shm files from /tmp cleaning in <a
+         href="https://man.openbsd.org/daily.8">daily(8)</a>. Removing them
+         interferes with programs that use shared memory via <a
+         href="https://man.openbsd.org/shm_open.3">shm_open(3)</a>.
+   <li>Added zap-to-char and zap-up-to-char to <a

+         M-z.

+   <li>Enabled the Data Independent Timing (DIT) feature in both the kernel and
+         userland on arm64 CPUs that support it to mitigate timing side-channel
+         attacks.
    </ul>
  <li>Changes in the network stack:
    <ul>
+         <li>Made /dev/pf a clonable device to better track kernel ressources
+                 used by processes.
+         <li>Modified TCP receive buffer size auto-scaling to use the smoothed
+                 RTT (SRTT) instead of the timestamp option, which improves performance
+                 on high latency networks if the timestamp option isn't available.
+         <li>Relaxed the requirement for multicast suppport of interfaces for
+                 configuring IPv6.  This allows non-multicast interfaces such as
+                 point-to-point interfaces and the NBMA / point-to-multipoint
+                 interfaces like mpe(4), mgre(4) and wg(4) to work with IPv6.

+         without problems, but have special meaning, for example a shell.
+   <li>Added <a

    <li>Added support for configuring interfaces by lladdr to support
