+Release 20180422
+    * Added NEWS file.
+    * Added -q option for quiet operation.
+    * Added -v option to output version information.
+    * Added USR1 signal handler that will stop the temporary directory
+      from being deleted when the shell exits (as if -k had been used from
+      the start).
+    * Let the configure script figure out whether "mktemp -t" adds
+      ".XXXXXXXX" to the end of the given template or not.
+    * Don't choke on directories whose name start with a dash.
+    * Now properly tested on FreeBSD 11.1.
+
+Release 20180415
+    * Fixed GitHub issue #1, "Centos 7 several shells with the same name".
+    * Fixed GitHub issue #2, "Comparison null string to zero (int)"
+    * Added manual.
+    * Added -f option to force running the given command (bypasses check
+      for valid login shell).
+    * Added -s option for specifying a "skeleton" directory whose
+      contents will be (recursively) copied into the newly created
+      temporary directory.
+    * Updated static list of shells on Solaris with shells from the
+      shells(4) manual on a Solaris 11.4-beta system.
+    * Set HOME to the temporary directory.
+
+Release 20180401

 Useful shell scripts
 
 How to use:
+
     The scripts are documented with their own manuals.  The same manuals
     are also available as plain text and Markdown in the "doc" directory
     of the source distribution.  These will also be installed in
     "<prefix>/share/doc/shell-toolbox" by default.
 
 How to install:
+
     Please see the document called "INSTALL" in the source distribution.
 
 Tested on:
-    OpenBSD 6.3, NetBSD 7.1.2, Darwin 17.5.0 (macOS High Sierra),
-    Ubuntu 17.10, Solaris 11.4, CentOS 7
