@@ -79,10 +79,64 @@ MISC:
  - Installed atomic switches for SIGTERM and SIGHUP. It is now a 
    statefull kill. SIGHUP can be used to signal conditions in future.
    Thanks to @SvenLie for the patch.
- - Rewrite the configure-script with autoconf. Features are now
-   enabled/disabled by CLI flags instead of environment variables.
-   The Makefile uses standardised variables from autoconf for the
-   installation directories and compiler flags.
+ - Rewrite the configure-script with autoconf.
+   - Generate configure with autoconf from autoconf.ac.
+   - License autoconf.ac under GPLv3 like the rest of the project.
+   - Replace Makefile and Makefile.inc with Makefile.in. The Makefile is
+     generated by configure from Makefile.in.
+   - Use macros from the Autoconf Macro Archive in configure.ac for the
+     detection of compile flags, the mysql, postgresql, sqlite3 and
+     openssl libraries and for bison and pthread support and place the
+     macros in the m4 subdirectory.
+   - Features are now enabled/disabled by CLI flags instead of environment
+     variables:
+     - --disable-sqlite replaces SQLITE=NO
+     - --disable-mysql replaces MYSQL=NO
+     - --disable-tls replaces TLS=NO
+     - --enable-postgres replaces POSTGRES=YES
+   - Compiler optimizations (-O2) are enabled by default when compiling
+     with gcc.
+   - The Makefile uses standardised variables from autoconf for the
+     compiler flags and installation directories like @sysconfdir@ for the
+     configfiles, @sbindir@ for the binaries, @docdir@ for the
+     documentation and @mandir@ for the manfiles.
+     - Use @sysconfdir@ instead of CONFDIR
+     - Use $(DESTDIR)$(sysconfdir) instead of FAKECDIR
+   - The Makefile uses variables from autoconf for calling the install
+     program in the install target. The variables can be overridden.
+   - Define the versionnumber and releasename in configure.ac instead of
+     main.h.
+   - Add some files to .gitignore which are autogenerated by the configure
+     script and some autotools. Remove the obsolete entry for Makefile.inc.
+   - Adapt the github actions workflow and the reflex.conf to the changed
+     configure script.
+ - Separate the variable UDBFILE in the Makefile into UDBFILE and UDBPATH
+   and use the UDBPATH in more places, to make it possible to install the
+   database to another location, by overriding the variable when calling
+   make.
+ - Separated the DESTDIR variable in the Makefile into DESTDIR (empty by
+   default and only included in the Makefile, not in configure) and prefix
+   (/usr/local by default and overridable when calling configure or make)
+ - Combine CFLAGS and BUILDFLAGS into CFLAGS in the Makefile.
+ - Do not change the permissions for files and directories with chmod
+   anymore. Pass for example "-m 0700" to the install command if special
+   permissions are needed or leave it out if the defaults from
+   @INSTALL_PROGRAM@ and @INSTALL_DATA@ are enough. This makes it possible
+   to change the behaviour by overriding the variables for INSTALL_PROGRAM
+   and INSTALL_DATA.
+ - Do not change the owner and group of the created files and directories
+   in the make install target. This change makes it possible to run
+   "make install" without root rights by setting the DESTDIR to a path
+   owned by the user.
+ - New make target to create the init.d_script by replacing the daemon-path
+   with a variable from autoconf.
+ - Remove the getver.sh script. The make target print_version uses
+   variables from autoconf instead.
+ - Use "-n" instead of "-g" as the flag for the sort command in the Make
+   target count because it is standardised and results in the same sorting.
+ - Also update the manpages when calling "make upgrade".
+ - Refactor make targets lex.yy.o and config.tab.o to avoid build failures
+   when lex.yy.c got deleted and avoid unnecessary recompilations.
 
 2.1.3-stable "Friedrichroda" : 17-Apr-2021:
  As usual, every new release gets named after a nice travel location.
