-1.1
+
+        - fdpass hardening:
+	   - limit cmsg->cmsg_len to controllen, as some buggy OSes
+             allow buffer overruns otherwise.
+           - do not leak fds on fdpass protocol failures.
+           - close extra fd's sent by non-compliant sender.
+
+2.0  Wed Aug  4 15:59:08 CEST 2021
+	- change build system to cmake.
+	- add pkg-config file.
+	- ptytty::login no longer writes a utmp, wtmp and lastlog
+	  record when utmpx is available.
+	- ptytty::login now provides the time with microseconds in
+	  utmpx, wtmpx and lastlogx records.
+
+1.8  Thu Feb 25 21:17:12 CET 2016
+	- fix m4 underquoting bug that prevented utmpx detection from
+	  working on systems without the utmp.h header, such as
+	  freebsd 9 and newer.
+	- fix ptytty::get hang on AIX.
+	- ptytty::get on Solaris no longer makes the tty controlling
+	  when the calling process does not have a controlling
+	  terminal. Bug introduced in ptytty-1.4.
+
+1.7  Thu Mar 19 22:04:33 CET 2015
+	- fix various bugs that prevented the lib from working correctly on
+	  some systems when using the helper process.
+	- fix compilation on solaris with g++ >= 4.7.
+	- fix compilation on freebsd/openbsd.
+	- nuke the pid check when !PTYTTY_REENTRANT: it breaks urxvtd, and
+          serves little purpose as it is off in normal builds anyway.
+	- add ecb.h.
+
+1.6  Sat Jan 21 16:59:22 CET 2012
+	- fix compilation on solaris.
+	- remove dependency on STL.
+
+1.5  Thu Dec 22 23:32:08 CET 2011
+	- INCOMPATIBLE CHANGE: ptytty::get no longer sets the pty fd
+	  non-blocking.
+	- the login_shell argument of ptytty::login is now properly
+	  honoured.
+	- ptytty::get no longer makes the pty a controlling terminal
+	  when using posix_openpt.
+	- remove support for utmpx ut_session extension, it serves no
+	  purpose.
+	- remove support for writing lastlog when the lastlog file is a
+	  directory, no system is known to require this code.
+	- do not clear ut_user in utmpx logout records because
+	  pututxline fails otherwise on solaris.
+	- fix writing of bsd style utmp when the tty is closed before
+	  calling ptytty::login.
+	- fix compilation on systems with bsd style utmp and no utmpx,
+	  such as openbsd.
+
+1.4  Wed Jun 29 14:36:19 CEST 2011
+	- push stream modules in ptytty::get rather than in
+	  ptytty::make_controlling_tty. This makes tty ioctls (such as
+	  TIOCSWINSZ, to set the window size) work even if
+	  make_controlling_tty has not been called.
+	- clear user and host fields in utmp(x) logout records.
+	- fix utmpx detection on upcoming FreeBSD 9.
+	- switch to automake.
+	- refactoring and cleanup.
+
+1.3  Sun May  3 23:44:16 CEST 2009
+	- fedora 9 apparently has isastream but not the stropts.h header
+          file for it, work around this (reported by Tuncer Ayaz).
+        - detect if lastlog is a directory at runtime.
+        - assume ttyslot availability for bsd style utmp.
+        - make sure the alignment for fd passing control messages
+          is correct and work around some NetBSD issues (Taylor R Campbell).
+        - add some missing include statements.
+
+1.2  Thu Aug  2 15:50:02 CEST 2007
+        - restore the SysV way of acquiring a controlling terminal
+          (for systems having no TIOCSCTTY such as cygwin or solaris).
+        - when using openpty, get the slave name with ttyname.
+        - fix invalid free when using _getpty.
+        - update config.guess and config.sub.
+
+1.1  Mon Feb 12 18:25:07 CET 2007
         - when using the helper, close the pty and tty fd also in the main
-          process (Patch by Andrei Paskevich).
+          process (patch by Andrei Paskevich).
+        - implement ptytty::sanitise_stdfd to ensure stdin/out/error exist
+          and are usable and use it.
 
 1.0  Tue Oct  3 13:18:00 CEST 2006
-	- do not call chmod/chown with 0 argument when pty never opened.
+        - do not call chmod/chown with 0 argument.
         - reformatted ptytty.C to hopefully be more clear.
 
 0.2  Thu Jul 20 04:57:26 CEST 2006
-	- move include files outside #ifdef PTYTTY_HELPER in proxy.C.
+        - move include files outside #ifdef PTYTTY_HELPER in proxy.C.
         - added proxy.C to cvs (was missing before).
 
 0.1  Wed Jan 25 22:56:36 CET 2006
-	- added the C API.
+        - added the C API.
         - small freebsd patch to fdpass.C by Thierry Thomas.
         - added eg/c-sample.c.
         - small fixes to the C api.
