+
+The major news, as per the title, is that a port to FreeBSD arm64 (or aarch64) is now ready.
+The next steps are to get it reviewed and pushed upstream.
+
+Valgrind 3.23 is due out at the end of April 2024 and package:devel/valgrind[] will be updated shortly after that.
+
+package:devel/valgrind-devel[] will get an update as soon as I have pushed the changes for arm64.
+
+`--track-fds=yes` now checks for and warns about attempts to close a file decriptor more than once.
+Handling of closefrom has been improved to use this feature.
+
+There are some important fixes for FreeBSD 15, in particular handling the new `libsys`.
+
+Here is a list of smaller bugfixes:
+
+* Support for FreeBSD 13.3 has been added.
+* Added a redirect for `reallocarray`.
+* Several fixes for `aio*` functions.
+* Added a redirect for `memccpy`.
+* There is a fix for `_umtx_op OP_ROBUST_LISTS`.
+* Added redirects for C23 `free_sized` and `free_aligned_sized`.
+* Correctly propagate the ELF stack protection flags to the guest stack that Valgrind synthesizes.
+* Fixes for `--sanity-level-3` and above (only used for Valgrind self-testing at runtime).
+* Several fixes to checking done for `semctl`.
+* Fixed argument checking for `utrace`.
+* Fixed argument checking for `clock_nanosleep`.
