+
+The package:devel/valgrind-devel[] port had an intermediate update which was submitted on 2023-02-20.
+This contains most of what will be in the official release of Valgrind 3.21 which is due out shortly after this status report.
+
+There is a nice improvement to the vgdb interface.
+It's now much easier to see which bits of memory are initialized or not.
+There are a couple of fixes to the thread checks done by Helgrind.
+
+For FreeBSD specifically, the address space limit has been raised to be the same as Linux and Solaris on amd64.
+It was 32Gbytes and now it is 128Gbytes.
+The `kern.proc.pathname.PID` man:sysctl[3] has been fixed so that it returns the path of the guest exe and not that of the Valgrind host.
+At the same time I fixed some `_umtx_op` false positives and corrected auxv `AT_EXECPATH` in a way similar to `kern.proc.pathname.PID`.
+Syscall wrappers have been added for man:sctp_generic_sendmsg[2] and man:sctp_generic_recvmsg[2].
+
+Not yet available in the ports versions of Valgrind, there is a workaround for the use of man:rfork[2].
+Previously, since it is not supported, it would cause Valgrind to abort.
+Now it fails gracefully setting either EINVAL or ENOSYS.
+The main use of this system call is in man:posix_spawn[3], which will fall back to using man:vfork[2].
+
+The man:mknodat[2] syscall wrapper was incorrectly implemented on i386 and has now been fixed.
+
+There is a reworking of all of the aligned allocation functions so that they behave less like Linux glibc and more like the Valgrind build platform.
