-## New features since r1510XX
+## New features since r151046
 
 ### System Features
 
+* OmniOS userland is now built with gcc version 13.
+
+* A number of improvements to datalink management have been integrated from
+  upstream illumos. Known problems that could cause zones to get stuck
+  while shutting down have been resolved.
+
+* A number of issues with managing interface state around IPv6 address have
+  been resolved in this release.
+
+* Support for Zen 4 CPU performance counters has been added.
+
+* Use automatic IBRS on AMD Zen 4 platforms. This improves performance
+  and reduces the overhead of virtual machine context switching.
+
+* A number of improvements to the in-kernel CIFS/SMB support have been imported
+  from upstream illumos.
+
+* The lofi(4D) driver now supports DISCARD/TRIM.
+
+* Support for SMBIOS 3.7 has been added.
+
 ### Commands and Command Options
 
+* The `which` command has been replaced with an implementation written in C
+  rather than in csh. The new version bases its decision on what the current
+  user can execute on assigned privilege and not just file mode bits, so
+  the output may be different in some cases. The new version does also not
+  show csh alias expansions when invoked from csh, but note that tcsh is not
+  affected by this as it has a built-in `which` command.
+
+* There is a new datalink property, `media`, which shows the media that is in
+  use, as reported by the underlying driver. This new property is also present
+  in the topology tree.
+
+* The `ld` command parameter parsing has been tightened up, meaning that
+  invalid combinations of options are now rejected as they should be.
+
+* While it has always been supported, `make -w` is now documented in
+  [make(1)](https://man.omnios.org/man1/make).
+
+* The [svccfg(8)](https://man.omnios.org/svccfg) has gained a `-z` option,
+  allowing it to operate on services within a non-global zone.
+
+* `ping` would fail if given an interval of 0.01 seconds.
+
+* `prtconf -dp` now works as the man page would suggest. Previously `-d` was
+  ignored in the presence of `-p`.
+
+* `printmgr` has been removed. It has not been functional with modern java
+  for a long time.
+
+* [snoop(8)](https://man.omnios.org/snoop) can now capture into rotating
+  output files via the new `-O` option.
+
+* [ucodeadm(8)](https://man.omnios.org/ucodeadm) has gained a `-t` option
+  to specify the type of the microcode file being processed, rather than
+  relying on the file name.
+
+* `dtrace` performance has been improved when setting up or tearing down many
+  probes on systems with a high cpu count.
+
+* `truss` could fail to properly trace processes after switching data
+  model.
+
 ### Libraries and Library Functions
 
+* The uuid library is now shipped with a pkg-config file to make using this
+  easier from external software.
+
+* libuuid could previously produce invalid V4 UUIDs.
+
+* Name resolution for a DNS name which resolved only to multiple AAAA records
+  would previously fail.
+
+* The [getaddrinfo(3socket)](https://man.omnios.org/man3socket/getaddrinfo)
+  function now supports being called with a socket type of ANY and with
+  `AI_NUMERICSERV` present in the flags.
+
+* A possible double free in `getallifaddrs()` has been fixed.
+
+* [strtonumx(3C)](https://man.omnios.org/strtonumx) has been added as a
+  companion to the existing `strtonum(3C)` function.
+
 ### Zones
 
-### LX zones
+* A new experimental `emu` zone brand for running emulated systems (under qemu)
+  is available. There is an example walk-through of using this to boot
+  the experimental OmniOS aarch64/arm64 distribution in an emu-branded zone
+  at https://omnios.org/setup/zadm
+
+### LX Zones
+
+* Booting a busybox distribution in an LX zone could previously corrupt the
+  `/etc/init.d/networking` file in the zone.
+
+* The `AT_SECURE` auxval is now always set for the root user. This improves
+  compatibility with some applications.
+
+* The `IPV6_RECVERR` socket option is now accepted by setsockopt(). It is
+  implemented as a no-op, in the same way as `IP_RECVERR`, but it no longer
+  generates an error which sates some applications.
 
 ### Bhyve
 
-### ZFS
+* Guest page table population is now significantly faster, which improves
+  guest boot times.
+
+* The `viona` virtual network driver now copies transmission buffers by default
+  when handing them off. This improves situations when it was possible to
+  starve the system of buffers on high bandwidth connections.
+
+* A number of improvements have been made to the real-time clock within
+  bhyve.
 
 ### Package Management
 
+* [pkg list](https://man.omnios.org/man1/pkg) has gained `-o` and `-F` options
+  to control which columns are included in the output, and the format of
+  that output.
+
+* [pkg list -i](https://man.omnios.org/man1/pkg) shows installable packages.
+  These are packages which are available in the catalogue but are not installed
+  on the current system image.
+
+* When packaging software, the `pkgdepend resolve` step would previously
+  consume excessive memory.
+
 ### Hardware Support
 
-### Installer
+* NVMe 2.x devices are now supported, although currently only with NVMe 1.x
+  features.
+
+* ATA PASS-THROUGH(16) is now supported. This enables the use of
+  `smartctl` command on SATA disks without having to force the pass-through
+  mode via `-d sat,12`.
 
-### Virtualisation
+* Kernel support for newer AMD CPU revisions and socket types has been
+  introduced.
+
+* The bundled firmware for cxgbe network cards has been updated to version
+  1.27.4.0.
+
+* The cxgbe driver now produces kstats for FEC events.
 
 ### Developer Features
 
+* Version 13 of the `gcc` compiler has been added.
+
+* The performance of the warning check phase of `nightly` has been
+  significantly improved.
+
 ### Deprecated features
 
-* The `grub` boot loader is deprecated and has been removed in the r151048
+* The `grub` boot loader is deprecated and will be removed in a future
   release. It will be supported in r151046 for the full LTS time frame, up to
   May 2026. If you have not yet migrated to the new boot loader, and would like
   assistance, please
   [get in touch](https://omnios.org/about/contact).
 
+* Version 11 of the `gcc` compiler has been removed. Existing installed packages
+  will be retained but no longer receive updates.
+
 * OpenSSL 1.0.x and 1.1.1 are deprecated and reached end-of-support at the end
   of 2019 and in September 2023 respectively.
   OmniOS has transitioned to OpenSSL 3 and still ships older versions for
