+This document details the changes between this version, bash-3.1-beta1,
+and the previous version, bash-3.1-alpha1.
+
+1.  Changes to Bash
+
+a.  Added some system-specific signal names.
+
+b.  Fixed a typo in the ulimit builtin to make `x' the right option to
+    maniuplate the limit on file locks.
+
+c.  Fixed a problem with using += to append to index 0 of an array variable
+    when not using subscript syntax.
+
+d.  A few changes to configure.in to remove calls to obsolete or outdated
+    macros.
+
+e.  Make sure changes to variables bash handles specially (e.g., LC_ALL) are
+    made when the variable is set in the temporary environment to a command.
+
+f.  Make sure changes to variables bash handles specially (e.g., LC_ALL) are
+    made when the variable is modified using `printf -v'.
+
+g.  The export environment is now remade on cygwin when HOME is changed, so
+    DLLs bash is linked against pick up the new value.  This fixes problems
+    with tilde expansion when linking against and already-installed readline.
+
+h.  Small fix to the logic for performing tilde expansion in posix mode, so
+    expansion on the right-hand side of an assignment statement takes place.
+
+i.  Fixed a bug that prevented redirections associated with a shell function
+    from being executed when in a subshell.
+
+j.  Fixed `source' and `.' builtins to not require an executable file when
+    searching $PATH for a file to source.
+
+k.  Fixed a bug that caused incorrect word splitting in a function when IFS
+    was declared local, then unset.
+
+l.  Fixed a problem with the `kill' builtin that prevented sending signals
+    to a process group under certain circumstances when providing a pid < 0.
+
+m.  When in POSIX mode, `pwd' now checks that the value it prints is the same
+    directory as `.', even when displaying $PWD.
+
+n.  Fixed a problem with the `read' builtin when reading a script from standard
+    input and reading data from the same file.
+
+o.  Fixed a problem with the `type' and `command' builtins that caused absolute
+    pathnames to be displayed incorrectly.
+
+p.  Some changes to the `bg' builtin for POSIX conformance.
+
+q.  The `fc' builtin now removes the `fc' command that caused it to invoke an
+    editor on specified history entries from the history entirely, rather than
+    simply ignoring it.
+
+r.  When in POSIX mode, the `v' command in vi editing mode simply invokes vi
+    on the current command, rather than checking $FCEDIT and $EDITOR.
+
+s.  Fixed a small memory leak in the pathname canonicalization code.
+
+t.  Fixed a bug that caused the expanded value of a $'...' string to be
+    incorrectly re-quoted if it occurred within a double-quoted ${...}
+    parameter expansion.
+
+2.  Changes to Readline
+
+a.  The `change-case' command now correctly changes the case of multibyte
+    characters.
+
+b.  Changes to the shared library construction scripts to deal with Windows
+    DLL naming conventions for Cygwin.
+
+c.  Fixed the redisplay code to avoid core dumps resulting from a poorly-timed
+    SIGWINCH.
+
+d.  Fixed the non-incremental search code in vi mode to dispose of any current
+    undo list when copying a line from the history into the current editing
+    buffer.
+
+e.  The variable assignment code now ignores whitespace at the end of lines.
+
+3.  New Features in Bash
+
+a.  A new configuration option, `--enable-strict-posix-default', which will
+    build bash to be POSIX conforming by default.
+
+4.  New Features in Readline
+
