Release notes for FreeBSD 13.0.
This file describes new user-visible features, changes and updates relevant to
users of binary FreeBSD releases. Each entry should describe the change in no
more than several sentences and should reference manual pages where an
interested user can find more information. Entries should wrap after 80
columns. Each entry should begin with one or more commit IDs on one line,
specified as a comma separated list and/or range, followed by a colon and a
newline. Entries should be separated by a newline.
Changes to this file should not be MFCed.
r350307:
libcap_random(3) has been removed. Applications can use native
APIs to get random data in capability mode.
r349352:
nand(4) and related components have been removed.
r349349:
The UEFI loader now supports HTTP boot.
r349335:
bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
guests to play to and record audio data from the host.
r349286:
swapon(8) can now erase a swap device immediately before enabling it,
similar to newfs(8)'s -E option. This behaviour can be specified by
adding -E to swapon(8)'s command-line parameters, or by adding the
"trimonce" option to a swap device's /etc/fstab entry.
r347908-r347923:
The following network drivers have been removed: bm(4), cs(4), de(4),
ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
vx(4), wb(4), xe(4).

NOTE: FreeBSD has switched from gcc to clang. If you have trouble bootstrapping
from older versions of FreeBSD, try WITHOUT_CLANG and WITH_GCC to bootstrap to
the tip of head, and then rebuild without this option. The bootstrap process
from older version of current across the gcc/clang cutover is a bit fragile.

Default permissions on the /var/account/acct file (and copies of it
rotated by periodic daily scripts) are changed from 0644 to 0640
because the file contains sensitive information that should not be
world-readable. If the /var/account directory must be created by
rc.d/accounting, the mode used is now 0750. Admins who use the
accounting feature are encouraged to change the mode of an existing
/var/account directory to 0750 or 0700.

Entropy collection and the /dev/random device are no longer optional
components. The "device random" option has been removed.

.SH SYNOPSIS
@ -762,6 +762,8 @@ The default is to ring the terminal bell in all such cases.
.IP "\-Q or \-\-QUIET or \-\-SILENT"
Causes totally "quiet" operation:
the terminal bell is never rung.
If the terminal has a "visual bell", it is used in all cases
where the terminal bell would have been rung.
.IP "\-r or \-\-raw-control-chars"
Causes "raw" control characters to be displayed.
The default is to display control characters using the caret notation;
@ -938,21 +940,48 @@ If the reopen succeeds and the file is a different file from the original
with the same name as the original (now renamed) file),
.I less
will display the contents of that new file.
.IP "\-\-mouse"
Enables mouse input:
scrolling the mouse wheel down moves forward in the file,
scrolling the mouse wheel up moves backwards in the file,
and clicking the mouse sets the "#" mark to the line
where the mouse is clicked.
The number of lines to scroll when the wheel is moved
can be set by the \-\-wheel-lines option.
Mouse input works only on terminals which support X11 mouse reporting,
and on the Windows version of
.IR less .
.IP "\-\-MOUSE"
Like \-\-mouse, except the direction scrolled
on mouse wheel movement is reversed.
.IP "\-\-no-keypad"
Disables sending the keypad initialization and deinitialization strings
to the terminal.
This is sometimes useful if the keypad strings make the numeric
keypad behave in an undesirable manner.
.IP "\-\-use-backslash"
This option changes the interpretations of options which follow this one.
After the \-\-use-backslash option, any backslash in an option string is
removed and the following character is taken literally.
This allows a dollar sign to be included in option strings.
.IP "\-\-no-histdups"
This option changes the behavior so that if a search string or
file name is typed in, and the same string is already in the history list,
the existing copy is removed from the history list before the new one is added.
Thus, a given string will appear only once in the history list.
Normally, a string may appear multiple times.
.IP "\-\-rscroll"
This option changes the character used to mark truncated lines.
It may begin with a two-character attribute indicator like LESSBINFMT does.
If there is no attribute indicator, standout is used.
If set to "-", truncated lines are not marked.
.IP "\-\-save-marks"
Save marks in the history file, so marks are retained
across different invocations of \fIless\fP.
.IP "\-\-use-backslash"
This option changes the interpretations of options which follow this one.
After the \-\-use-backslash option, any backslash in an option string is
removed and the following character is taken literally.
This allows a dollar sign to be included in option strings.
.IP "\-\-wheel-lines=\fIn\fP"
Set the number of lines to scroll when the mouse wheel is scrolled
and the \-\-mouse or \-\-MOUSE option is in effect.
The default is 1 line.
.IP \-\-
A command line argument of "\-\-" marks the end of option arguments.
Any arguments following this are interpreted as filenames.
