    14-12-02  The requirement that unquoted { and } must match inside string with

    	  could cause in infinite loop has been fixed.
    14-11-25 +If tab completion for a command name that is an alias is attempted,

    14-07-21 +A -m method option has been added to read to read compound variables
    	  using a specified method. Currently only methods ksh and json are

    14-06-25 +The -D and -E options have been added to the complete builtin.
    14-06-19  References to dgk@research.att.com were deleted.
    14-06-19 +The -l flag to trap and the -p flag to umask were added as in bash.
    14-06-17 +In bash mode ${!parameter} is treated like ${$parameter}.
    14-06-17  Fixed a bug in which eval inside a dot script invoked by a profile file
    	  terminated the dot script prematurely after running the eval command.
    14-06-16 +Added parameter expansion operator ${$parameter} for variables and
    	  positional parameters.

    14-06-02 +When compiled with the SHOPT_BASH and run with the name bash,
    	  the shell now uses dynamic scoping for name() and function name.
    	  In addition the builtins declare and local are supported.
    	  The SHOPT_BASH option is on by default in the Makefile.
    	  More work remains with the bash compatibility option.
    14-05-25  Fixed a bug in vi command completion in which tab did not work
    	  after a space.
    14-05-25 +Replaced the -p option for read with -p prompt.  For backword
    	  compatibility, if a coprocess is running and prompt begins with -
    	  or is a valid variable name, -p causes the read from a pipe.
    14-05-25 +Modified the -u option for read and print so that it accepts the
    	  option argument p to indicate the coprocess file descriptor.
    14-05-08  A bug in the option parser which could cause 'X -a v=((...)...) to
    	  core dump has been fixed.
    14-05-07  A change to improve the performance of appending an element to an
    	  array has been fixed.
    14-05-02 +A compilation option to add programmable completion with the two
    	  new builtins, complete and compgen has been added.  It should behave
    	  the same as it does with bash.  Please try this out and report any
    	  problems you find.  Use compgen --man and complete --man to get the
    	  man pages.  Use the bash documentation for now for information about
    	  programmable completion.  The compilation is on by default for now.
    14-04-05  A bug in which type name starting with the letter a, did not
    	  allow instances to be created has been fixed.
    14-04-03  A bug which caused a syntax error when a here-doc was embedded
    	  in `` command substitution has been fixed.
    14-03-31  A bug in `` command substition of a pipeline which could cause
    	  memory problems has been fixed.

    	  been fixed.
    14-01-23  The value of errno is now saved and restored during shell interrupt
    	  handlers.
    14-01-21  A bug in which a read from a script invoked with set -m could stop
    	  when trying to read, and cause the parent to try to restart which
    	  causes a loop has been fixed.
    14-01-20  A bug in the right shift operator in arithmetic expressions when the
    	  shift count is greated then the number of bits in a long integer has
    	  been fixed.

    	  functions has been fixed.
    14-01-09  A second bug in which appending to an empty array of types does
    	  starts with element 1 rather than 0 has been fixed.
    14-01-06  A bug which could cause a core dump when KSH_VERSION is exported in
    	  the envirnment has been fixed.  KSH_VERSION is a name reference to
