** New operation mode: proxy

** Command line option precedence

Command line options take precedence over configuration file
statements.

** elif statement

A familiar `elif' statement is supported, e.g.:

if condition-1
  action-list-1
elif condition-2
  action-list-2
elif condition-3
  action-list-3
else
  action-list-4
fi
  
** New CONTROL statement esmtp-auth-delayed.

When set to `yes', this statement instructs Anubis to postpone ESMTP
authentication until MAIL command is issued by the client.  This
allows to change authentication credentials in the SMTP section (see
below).

** SMTP section

The new section "SMTP" is invoked each time an SMTP command
is received. This section may alter the command's argument, using the
"modify command", e.g.:

BEGIN SMTP
regex :extended
modify command [ehlo] "foo.bar.net"
if command ["mail from:"] "<(.*)>(.*)"
  modify command ["mail from:"] "<root@bar.net>\2"
fi
END

It is also allowed to use esmtp-* keywords in this section, provided
that `esmtp-auth-delayed yes' is set in the CONTROL section. Changes
in the ESMTP authentication credentials take effect if they occur
either before receiving MAIL command from the client, or when handling
this command, e.g.:

BEGIN SMTP
if command ["mail from:"] "<smith(\+.*)?@@example.net>"
  esmtp-auth-id smith
  esmtp-password guessme
else
  esmtp-auth no
fi
END

** New keywords: log-facility and log-tag

** Guile output

By default Scheme's standard error and output ports are redirected to
syslog, using priorities `err' and `warning' correspondingly.

** MySQL options file

When using MySQL for Anubis user database, the database parameters and
access credentials are read from the file /etc/my.cnf, section
"anubis".  Additionally, two URL parameters are provided:
"options-file", which sets the name of the options file, and
"options-group", which sets the name of the group.

	  

* Multiple start functions are allowed

The '--main' option can be given multiple times.  A separate graph
will be drawn for each function given as its argument.

* New option --target=FUNCTION

If this option is given, the produced graph will contain only paths
leading from start function (or functions) to the given FUNCTION.

Multiple '--target' options are allowed.

* New output format: dot

The '-f dot' (or '--format=dot') option instructs cflow to output
graph as a description in DOT language, suitable as input to graphviz
programs.

* cflow-mode: new commands for navigating in the graph:

  c   go to the calling function
  n   go to the next function at the same nesting level
  p   go to the previous function at the same nesting level

* Bugfixes:

** CVE-2019-16165
** CVE-2019-16166
** Fix parsing of K&R style function declarations
** Improve parsing of typecasts
** Fix recursive call detection

	  

* New option --ignore-dirnlink

Valid in copy-out mode, it instructs cpio to ignore the actual number
of links reported for each directory member and always store 2
instead.

* Changes in --reproducible option

The --reproducible option implies --ignore-dirlink.  In other words,
it is equivalent to --ignore-devno --ignore-dirnlink --renumber-inodes.

* Use GNU ls algorithm for deciding timestamp format in -tv mode

* Bugfixes

** Fix cpio header verification.

** Fix handling of device numbers on copy out.

** Fix calculation of CRC in copy-out mode.

* Bugfixes in the gcide module

* Fix searches in the gcider utility

* Support for Python 2 has been withdrawn

	  

* Introduce compound events

The "change" event is implemented on GNU/Linux and FreeBSD.  This
event is delivered when a file was modified and closed.

* New configuration statement for manipulating the environment.

The "environ" statement is now a compound statement. It can contain
five kinds of substatements: "clear" to clear the environment, "keep"
to retain certain variables while clearing the environment, "set" to
set a variable, "unset" to unset a variable or variables, and "eval"
to evaluate a variable reference for side effects.

Both "keep" and "unset" can take globbing pattern as their argument,
in which case they affect all variables matching that pattern. 

The value part in the "set" statement is subject to variable
expansion.

The "environ" block can appear in global context as well.  In this
case it applies to all watchers.

The support for the old one-line "environ" syntax is retained for
backward compatibility.

* Variable expansion in arguments to some configuration statements.

Both macro and environment variables are expanded in arguments to all
substatements of the new "environ" block statement and in the argument
to the "command" statement.  In the latter case, expansion of the
environment variables is controlled by the "shell" option.  If the
option is set, the variable will be expanded by the shell.  Otherwise,
they are expanded by direvent prior to invoking the command.

* Rewrite the recursive watching support

In particular, this fixes the bug where recursive watchers silently
assumed that the "create" generic event was configured for the
watcher.

* Change interface for bulk closing of file descriptors

To speed up launching of the user commands, system-dependent
interfaces for closing the file descriptors above the given one are
used, if available.
	  

* Bucket cache switched from balanced tree to hash table

Change suggested by Terence Kelly.

* Speed up flushing the changed buckets on disk

* New option codes for gdbm_setopt

** GDBM_GETDBFORMAT

Return the database format.

** GDBM_GETDIRDEPTH

Return the directory depth, i.e. the number of initial (most significant)
bits in hash value that are interpreted as index to the directory.

** GDBM_GETBUCKETSIZE

Return maximum number of keys per bucket.

** GDBM_GETCACHEAUTO

Return the status of the automatic cache adjustment.

** GDBM_SETCACHEAUTO

Enable or disable automatic cache adjustment.
	  

* ftp

An old inability to allow other names than the canonical name has
been corrected.  This means that a machine entry in the .netrc file
will now be used as expected.  Previously any alias name was replaced
by the corresponding canonical name, before reading the .netrc file.

The internal command `hash' accepts a suffixed letter to the size
argument, like `12k', instead of 12288.  Made a minor change to the
syntax of the command itself, allowing size changes independently
of activation of hash markings.  After a transfer the summary gives
the speed as `Mbytes/s', `kbytes/s', or `bytes/s'.

The .netrc file can be overridden by the environment variable NETRC.
Of even higher precedence is the new option `-N/--netrc'.  The access
to the resulting file, whatever method, is now denied unless it is a
regular file.

* ifconfig

Better command line parsing on BSD and Solaris systems.  Touch only
changeable flags on all systems.

* logger

The ability to use numerical facilities is restored to full range.

* ping, ping6

The ability to specify a pattern as payload is corrected.

* syslogd

A new switch `-T/--local-time' makes the service ignore a time
stamp passed on by the remote host, recording instead the local
time at the moment the message was received.  As a short form of
`--pidfile', the switch `-P' is new.

In common with other syslogd implementations, rsyslogd and sysklogd,
there has for a long time existed an attack vector based on large
facility numbers, made public in CVE-2014-3684.  This is now mended
in our code base.

* telnetd

The ability to autologin a client, without using authentication,
is now functional in the expected manner, i.e., the prompt for a
user name is suppressed in favour of an immediate password prompt.

In a setting where the client is using a UTF-8 encoding, it was
common to observe strange characters in most responses.  This was
caused by the server daemon, due to incomplete purging of internal
protocol data.  The issue should now be resolved.

* whois

Improved cooperation with servers like `whois.arin.net', `whois.eu',
and `whois.ripe.net'.
	  

* Support for Berkeley DB version 2 withdrawn

* Bugfixes
** rdcache streams: fix stream size computation
** tlsfdstr streams: fix error handling
** wordwrap streams: fix handling of overflowing lines
	  

* Appending cronjob output to a file

Output of a cronjob can be captured and appended to a disk file,
instead of sending it via email or logging it using syslog.  This is
controlled by the _MICRON_OUTFILE (global) and _JOB_OUTFILE (per-job)
built-in variables.

* New option -P FILE

Writes PID of the running process to FILE.  The file will be removed
when the program terminates.

* Option -v replaces -o

To set initial value of a built-in variable, use the "-v NAME=VALUE"
option.

* The -V option

To obtain the micrond version, use the -V option.

* Bugfixes

** Fix allocation of environment and built-in variables defined in crontabs.
	  

* New configuration keywords

** sigterm SIG

Available for use in "component" sections.  This statement defines
signal which pies should send to the running component instance in
order to terminate it.  Defaults to SIGTERM.

* Fix the component shutdown sequence

The shutdown sequence is determined taking into account dependencies
between components, so that all dependent components are stopped
before their prerequisite components.

* Fallback log file

Fallback log file is a place where pies writes out of band log messages,
i.e. messages about not being able to open syslog socket or send logs
to it.  Regular log messages are diverted to this file if syslog was
requested, but cannot be used because of a permanent error.

* Bugfixes

** Fix piesctl config reload

** Fix configuration preprocessing.

** Varios fixes in REST API server.
	  

* Configuration file raddb/config

The syslog statement takes an optional 4th argument specifying syslog
tag to use, e.g.:

    channel default {
	    syslog local1.info radiusd;
    };

* New attributes

** GNU-Server-Address

Holds IP address of the RADIUS server that recieved the
request. Notice, that the value of this attribute is "0.0.0.0" if
there are no `listen' statement in your `raddb/config'.
    
** GNU-Server-Port

Holds UDP port number of the RADIUS server that recieved the request.

* Automake function AM_GNU_RADIUS is provided, for checking if
GNU Radius is installed from configure.ac scripts.

* Guile support requires Guile version 1.8 or later.

* Bugfixes
** Pass NAS-IP-Address to mlc_stop_query
