** 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.

* New option --all (-A)

Produce graphs for all global functions in the program.  Use this
option if your program contains functions which are not directly
reachable from main().

The output consist of separate flow graphs for each global function
defined in the program.  These graphs will be placed after the graph
for main() (if it exists), and will be ordered lexicographically by
the function name.

* New option --no-main

This option has the same effect as '--all', except that the graph for
main() function (if it exists) is treated same way as all the other
graphs, i.e. it will not be placed at the top of output, but in its
place as per the lexicographic ordering of function names.

* Fix CVE-2016-2037
* Fix CVE-2019-14866

* Fix compilation with gcc 10

* Restore po files

* The path statement can refer to a regular file.

Prior versions of direvent required the argument to the "path"
statement to refer to an existing directory.  This requirement is now
lifted.  The pathname can refer to any type of file (not only a
directory).  Moreover, the file is not required to exist.  If it does
not exist, direvent will set up an auxiliary watcher (called a
"sentinel"), that will wake up upon creation of the file with that
pathname and will set up the configured watcher once it is created.

The process is reversed when the file referred to by the "path"
statement is deleted.  In that case, the configured watcher is
deactivated and a sentinel is set up which will bring it back when the
destination file or directory is created.

This mode of operation ensures that the configured watcher will always
be operational.

* Fix watcher removal on BSD-like systems.

* Configuration changes

** multiple environ statements

Multiple environ statements can be used within a single watcher block.
Such statements accumulate.

* Pre-read the memory mapped regions on systems that support it.

This speeds up operations on big databases.

* gdbmtool: tagged initialization of structured data

Initializers for structured data can be given in tagged form, e.g.:

   store somekey { status=2, id={a,u,x}, name="foo" }

* Bugfixes:

** Preserve locking type during database reorganization

* Fix expunging of mailboxes in mbox and dotmail format in a read-only directory

The bug was reported at https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=980042

* inc: when updating the "unseen" sequence, translate message numbers to uids

* Fix default port selection in SMTP mailer

* Fix building the mda utilities with mailbox quotas off

* Fix bugs in the testsuite

* Detect if pies is started from docker

This makes the --no-init option unnecessary.

* When running with PID 1, install SIGCHLD handler early

This is to make sure the exited preprocessor command is cleaned up
properly.

* Fix cyclic dependency detection

* New component flag: expandenv

The "expandenv" flag instructs pies to parse the command line
and to expand any references to environment variables within it
as the Bourne shell would have done it.  This allows for expanding
the environment variables without the overhead of actually running
the shell.

This flag is incompatible with the "shell" flag.  When both are used,
the preference is given to "shell" and a warning message to that
effect is issued.

* Component standard stream redirection rewritten from scratch

In particular, redirecting stdout/stderr to syslog no longer requires
starting an auxiliar process.

* The component.facility configuration statement is withdrawn

To specify a particular facility, use the fully qualified
facility.priority argument to the stdout or stderr statement, e.g.:

  stderr syslog local1.err;

* New configuration statement syslog.dev

The statement configures the socket to communicate with the syslog
daemon.  Its argument is either the file name of the local socket
or the IP[:PORT] specification, e.g.

  syslog {
     dev 172.31.255.252;
  }

* Global env section

The "env" section appearing in global context modifies the environment
for the main pies process.  This modified environment will be
inherited by all processes started by pies in the course of its normal
operation.

* New control endpoint /alive

HTTP response to GET /alive/PROG reflects the current state of the
component PROG: 200 if it is running, 503 if not, and 404 if there's
no such component.

* 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 Gule version 1.8 or later.

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

* Include updated wordsplit version (v1.0-7-g6ccb9ad)
* Allow for multiple EOLs and comments after the preface statement.
* Bugfix in the testcase 20.

* POSIX extended format headers do not include PID by default
    
The intent is to make binary-equivalent PAX archives easy to create.  If
POSIXLY_CORRECT is set, the POSIX standard default is used, which embeds
the pid.

* --delay-directory-restore works for archives with reversed member ordering

* Fix extraction of a symbolic link hardlinked to another symbolic link

* Wildcards in exclude-vcs-ignore mode don't match slash

* Fix the --no-overwrite-dir option
    
Given this option, previous versions of tar failed to preserve
permissions of empty directories and to create files under directories
owned by the current user that did not have the S_IWUSR bit set.

* Fix handling of chained renames in incremental backups

* Link counting works for file names supplied with -T

* Accept only position-sensitive (file-selection) options in file list files.
    
Using such options as -f, -z, etc. is senseless in a file list file and
bypasses option consistency checks in decode_options.  Therefore, 
only options related to file selection (a.k.a position-sensitive options)
are allowed in file list files.

* Language:
  . support of index subentries and sub-subentries with @subentry
  . new commands @seeentry and @seealso in index entries
  . no need to wrap Top node in @ifnottex - omitted automatically when
    processed with TeX
  . UTF-8 is the default input encoding

* texi2any
  . for HTML output, mark index nodes in menus and tables of contents
    with the 'rel' attribute of the 'a' tag.
  . TOP_NODE_UP is now only used in HTML if TOP_NODE_UP_URL is set.
    Also TOP_NODE_UP should now be formatted in the output format.
    In HTML TOP_NODE_UP should be suitable for inclusion in HTML 
    element attributes, so for instance should not contain elements.
  . support of noderename.cnf files has been removed
  . INPUT_PERL_ENCODING, INPUT_ENCODING_NAME, NODE_FILE_EXTENSION,
    NODE_FILENAMES, SHORTEXTN and TOP_NODE_FILE removed as customization
    variables.
  . TOP_NODE_FILE_TARGET now contains the extension.
  . error messages translated when the XS parser module is in use

* texi2dvi
  . unconditionally run in --batch mode, i.e. without stopping if there
    is a TeX error
  . keep on going after a TeX error if the index files changed
  . with --tidy (or --build-dir), avoid reading index files from previous
    runs where --tidy was not used

* info
  . for a tree search (with M-/), '}' and '{' work as well as 'M-}' and
    'M-{' to go through the results

* Distribution:
  . Several obsolete portability checks removed
  . gettext 0.20.1, automake 1.16.1
