+Version 1.8.90 (git)
+
+* return-code statement accepts negations
+
+Negated status codes or signal numbers can appear in the argument
+list to the "return-code" command.  The syntax is:
+
+  !0       any status code except 0
+  !EX_OK   same as above
+  !SIGQUIT any signal except SIGQUIT
+  !SIG+10  any signal except 10
+
+For example, the following statement:
+
+  return-code (!0, !SIGHUP, !SIGQUIT) {
+        notify root;
+  }
+
+will notify root user if the program exits with any status, except 0
+or gets terminated with any signal, except SIGHUP and SIGQUIT.
+
+
+Version 1.8, 2022-08-13
+
+* 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.
+
+Version 1.7, 2022-01-02
+
+* Changes in configuration preprocessing
+
+** Each included file is preprocessed separately.
+
+The built-in preprocessor is removed.  The #include and #include_once
+statements are now regular configuration statements.  Any files
+included as a result of #include or #include_once are preprocessed
+separately.  This differs from prior versions, were all includes were
+expanded first, the obtained material passed to the m4 and the
+resulting output was then parsed.
+
+This means that:
+
+1. The mess with two preprocessors (built-in and external) is now
+gone.
+
+2. Macros defined in a source file don't pollute the namespace of
+another sources.
+
+3. Error locations can be accurately determined.
+
+4. Preprocessor can emit forceful diagnostics (see below) to properly
+identify erroneous or otherwise suspicious constructs.
+
+** The `pp-setup' file is gone.
+
+By default, the preprocessor is started as `m4 -s -P' with additional
+set of -I options and eventual -D or -U options if these are used in
+the command line of pies.  Apart from this, no additional set up is
+performed.
+
+** The precedence of -I options is fixed
+
+The -I options are placed in the m4 command line before the options
+that configure the default search path.
+
+* New forceful diagnostics statements
+
+** #warning "TEXT"
+
+Emits warning.
+
+** #error "TEXT"
+
+Emits error message.  Further parsing continues, but will end with
+failure.
+
+** #abend "TEXT"
+
+Emits error message and stops further processing immediately.
+
+If `#error' or `#abend' is encountered, the effect is the same
+as if syntax error has been detected.  If it occurs at pies
+startup, the program will terminate abnormally.  If it occurs as
+part of the reload sequence in a running instance of pies, the
+configuration file will be rejected and old configuration will remain
+in effect.
+
+Version 1.6, 2021-07-07
+
+* Selecting preprocessor from the command line.
+
+Two command line options are provided to select the preprocessor to
+use instead of the default m4.  The --preprocessor=COMMAND option
+instructs pies to use COMMAND as preprocessor.  The --no-preprocessor
+option disables the use of the external preprocessor.
+
+The new command line options are available both in pies and in the
+client program piesctl.
+
+* piesctl: fix order in which configuration files are examined
+
+As stated in the documentation, program-specific configuration
+file piesctl.conf takes precedence over pies.conf.
+
+* Fix reloading of the configuration files.
+
+* Fix compilation with --disable-sysvinit
+
+Version 1.5, 2020-12-14
+
+* 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.
