a/util-linux-2.35.1-x86_64-1.txz:  Upgraded.
a/zerofree-1.1.1-x86_64-1.txz:  Added.
  Also queued up for the next installer build. Thanks to bifferos.
ap/sudo-1.8.31-x86_64-1.txz:  Upgraded.
  This update fixes a security issue:
  In Sudo before 1.8.31, if pwfeedback is enabled in /etc/sudoers, users can
  trigger a stack-based buffer overflow in the privileged sudo process.
  (pwfeedback is a default setting in some Linux distributions; however, it
  is not the default for upstream or in Slackware, and would exist only if
  enabled by an administrator.) The attacker needs to deliver a long string
  to the stdin of getln() in tgetpass.c.
  For more information, see:
    https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-18634
  (* Security fix *)
n/NetworkManager-1.22.6-x86_64-1.txz:  Upgraded.
n/openldap-client-2.4.49-x86_64-1.txz:  Upgraded.
xfce/Thunar-1.8.11-x86_64-1.txz:  Removed.
xfce/thunar-1.8.12-x86_64-1.txz:  Added.
  Changed package name from "Thunar" to "thunar" to follow upstream's naming.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description. Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in. You must
+# make exactly 11 lines for the formatting to be correct. It's also
+# customary to leave one space after the ':'.

+zerofree: zerofree (zero free blocks from ext* filesystems)
+zerofree:
+zerofree: Zerofree finds the unallocated, non-zeroed blocks in an ext2, ext3,
+zerofree: or ext4 filesystem and fills them with zeroes. This is useful if the
+zerofree: device on which this file-system resides is a disk image. In this
+zerofree: case, depending on the type of disk image, a secondary utility may be
+zerofree: able to reduce the size of the disk image after zerofree has been run.

+
+    <para>The usual way to achieve the same result (zeroing the
+       unallocated blocks) is to run <command>dd</command> (1) to
+       create a file full of zeroes that takes up the entire free
+       space on the drive, and then delete this file. This has many
+       disadvantages, which zerofree alleviates:</para>

+
+    <para><replaceable>filesystem</replaceable> has to be unmounted or
+    mounted read-only for <command>&dhpackage;</command> to work. It
+    will exit with an error message if the

+    remount the root file-system readonly, you can first switch to
+    single user runlevel (<command>telinit 1</command>) then use
+    <command>mount -o remount,ro
+    <replaceable>filesystem</replaceable></command>.</para>
