h.  Fixed a bug that caused child processes to inherit the wrong value for $!.

i.  Fixed a bug that caused `.' to fail to read and execute commands from non-
    regular files such as devices or named pipes.

s.  Fixed a bug that caused jumps back to the top-level processing loop from
    a builtin command to leave the shell in an inconsistent state.

t.  Fixed a bug that caused characters that would be escaped internally to be

    when they were used in redirections.

ff. Fixed a problem that caused the shell to attempt to read from the standard
    input when called as `bash -i script'.

    in the pathname as quoting characters.

pp. Fixed a bug in the replacement getcwd() implementation that could cause
    memory to be overwritten.

qq. When in Posix mode, the `ulimit' builtin now uses a block size of 512 for
    the `-c' and `-f' options.

rr. Brace expansion now allows process substitutions to pass through unchanged.

ss. Fixed a problem in the command name completion code to avoid quoting

    by a shell begun to run a command substitution being placed into the
    wrong process group.

zz. Fixed a bug that caused the results of successful tilde expansion to be
    subject to pathname expansion and word splitting.

     when the variables were unset as part of the shell reinitializing itself
     to execute a shell script.

ttt. Fixed a bug that caused the history to not be saved after `history -c' or
     `history -d' was executed until a sufficient number of commands had been
     saved to the history.

uuu. Bash now parses command substitutions according to Posix rules: parsing
     the command contained in $() to find the closing delimiter.

     not persist.

www. Fixed a bug that didn't allow SIGCHLD to interrupt the `wait' builtin
     as Posix specifies.

xxx. Invalid numeric arguments to shell builtins no longer cause the shell to
     short-circuit any executing compound command.

yyy. Fixed a bug that caused the exit status to be lost when `break' was
     used to short-circuit a loop's execution.

zzz. Fixed a bug that caused stray ^? characters to be left in expansions of

aaaa. Bash now prints better error messages for here documents terminated by
      EOF and for identifying the incorrect token in an invalid arithmetic
      expression.

bbbb. Fixed a bug in the variable length word expansion that caused it to
      incorrectly calculate the number of multibyte characters.

      group was changed by a child of a child of the shell.

dddd. Fixed a bug that caused here documents belonging to commands within a
      compound command to be displayed in a syntactially-incorrect form, which
      prevented them from being re-read as input.

eeee. The shell displays more warnings about failures to set the locale.

ffff. Fixed a bug that caused the body of a here-document to not be saved to
      the history list.

gggg. Fixed a bug that caused configure to incorrectly conclude that FreeBSD
      had /dev/fd available, resulting in problems with process substitution.

2.  Changes to Readline

a.  Fixed a number of redisplay errors in environments supporting multibyte 
    characters.

b.  Fixed bugs in vi command mode that caused motion commands to inappropriately
    set the mark.

c.  When using the arrow keys in vi insertion mode, readline allows movement
    beyond the current end of the line (unlike command mode).

    away and reads return -1/EIO.

e.  Fixed bugs in redisplay occurring when displaying prompts containing
    invisible characters.

    or no characters following the final newline.

k.  Fixed redisplay bug caused by prompts consisting solely of invisible
    characters.

l.  Fixed a bug in the code that buffers characters received very quickly in
    succession which caused characters to be dropped.

m.  Fixed a bug that caused readline to reference uninitialized data structures
    if it received a SIGWINCH before completing initialzation.

n.  Fixed a bug that caused the vi-mode `last command' to be set incorrectly
    and therefore unrepeatable.

o.  Fixed a bug that caused readline to disable echoing when it was being used
    with an output file descriptor that was not a terminal.

p.  Readline now blocks SIGINT while manipulating internal data structures
    during redisplay.

q.  Fixed a bug in redisplay that caused readline to segfault when pasting a
    very long line (over 130,000 characters).

    characters.

3.  New Features in Bash

a.  When using substring expansion on the positional parameters, a starting
    index of 0 now causes $0 to be prefixed to the list.

b.  The `help' builtin now prints its columns with entries sorted vertically
    rather than horizontally.

c.  There is a new variable, $BASHPID, which always returns the process id of
    the current shell.

d.  There is a new `autocd' option that, when enabled, causes bash to attempt
