+This document details the changes between this version, bash-3.2-release,
+and the previous version, bash-3.2-beta.
+
+1. Changes to Bash
+
+a. Fixed a bug that caused the temporary environment passed to a command to
+ affect the shell's environment under certain circumstances.
+
+b. Fixed a bug in the printf builtin that caused the %q format specifier to
+ ignore empty string arguments.
+
+c. Improved multibyte character environment detection at configuration time.
+
+d. Fixed a bug in the read builtin that left spurious escape characters in the
+ input after processing backslashes when assigning to an array variable.
+
+2. Changes to Readline
+
+a. Fixed a redisplay bug that occurred in multibyte-capable locales when the
+ prompt was one character longer than the screen width.
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-3.2-beta,
+and the previous version, bash-3.2-alpha.
+
+1. Changes to Bash
+
+a. Changed the lexical analyzer to treat locale-specific blank characters as
+ white space.
+
+b. Fixed a bug in command printing to avoid confusion between redirections and
+ process substitution.
+
+c. Fixed problems with cross-compiling originating from inherited environment
+ variables.
+
+d. Added write error reporting to printf builtin.
+
+e. Fixed a bug in the variable expansion code that could cause a core dump in
+ a multi-byte locale.
+
+f. Fixed a bug that caused substring expansion of a null string to return
+ incorrect results.
+
+g. BASH_COMMAND now retains its previous value while executing commands as the
+ result of a trap, as the documentation states.
+
+2. Changes to Readline
+
+a. Fixed a bug with prompt redisplay in a multi-byte locale to avoid redrawing
+ the prompt and input line multiple times.
+
+b. Fixed history expansion to not be confused by here-string redirection.
+
+c. Readline no longer treats read errors by converting them to newlines, as
+ it does with EOF. This caused partial lines to be returned from readline().
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-3.2-alpha,
+and the previous version, bash-3.1-release.
+
+1. Changes to Bash
+
+a. Fixed a source bug that caused the minimal configuration to not compile.
+
+b. Fixed memory leaks in error handling for the `read' builtin.
+
+c. Changed the [[ and (( compound commands to set PIPESTATUS with their exit
+ status.
+
+d. Fixed some parsing problems with compound array assignments.
+
+e. Added additional configuration changes for: NetBSD (incomplete multibyte
+ character support)
+
+f. Fixed two bugs with local array variable creation when shadowing a variable
+ of the same name from a previous context.
+
+g. Fixed the `read' builtin to restore the correct set of completion functions
+ if a timeout occurs.
+
+h. Added code to defer the initialization of HISTSIZE (and its stifling of the
+ history list) until the history file is loaded, allowing a startup file to
+ override the default value.
+
+i. Tightened up the arithmetic expression parsing to produce better error
+ messages when presented with invalid operators.
+
+j. Fixed the cross-compilation support to build the signal list at shell
+ invocation rather than compile time if cross-compiling.
+
+k. Fixed multibyte support for non-gcc compilers (or compilers that do not
+ allow automatic array variable sizing based on a non-constant value).
+
+l. Several fixes to the code that manages the list of terminated jobs and
+ their exit statuses, and the list of active and recently-terminated jobs
+ to avoid pid aliasing/wraparound and allocation errors.
+
+m. Fixed a problem that allowed scripts to die due to SIGINT while waiting
+ for children, even when started in the background or otherwise ignoring
+ SIGINT.
+
+n. Fixed a bug that caused shells invoked as -/bin/bash from not being
+ recognized as login shells.
+
+o. Fixed a problem that caused shells in the background to give the terminal
+ to a process group other than the foreground shell process group.
+
+p. Fixed a problem with extracting the `varname' in ${#varname}.
+
+q. Fixed the code that handles SIGQUIT to not exit immediately -- thereby
+ calling functions that may not be called in a signal handler context --
+ but set a flag and exit afterward (like SIGINT).
+
+r. Changed the brace expansion code to skip over braces that don't begin a
+ valid matched brace expansion construct.
+
+s. Fixed `typeset' and `declare' to not require that their shell function
+ operands to be valid shell identifiers.
+
+t. Changed `test' to use access(2) with a temporary uid/euid swap when testing
+ file attributes and running setuid, and access(2) in most other cases.
+
+u. Changed completion code to not attempt command name completion on a line
+ consisting solely of whitespace when no_empty_command_completion is set.
+
+v. The `hash' builtin now prints nothing in posix mode when the hash table is
+ empty, and prints a message to that effect to stdout instead of stderr
+ when not in posix mode.
+
+w. Fixed a bug in the extended pattern matching code that caused it to fail to
+ match periods with certain patterns.
+
+x. Fixed a bug that caused the shell to dump core when performing filename
+ generation in directories with thousands of files.
+
+y. Returned to the original Bourne shell rules for parsing ``: no recursive
+ parsing of embedded quoted strings or ${...} constructs.
+
+z. The inheritence of the DEBUG, RETURN, and ERR traps is now dependent only
+ on the settings of the `functrace' and `errtrace' shell options, rather
+ than whether or not the shell is in debugging mode.
+
+aa. Fixed a problem with $HOME being converted to ~ in the expansion of
+ members of the DIRSTACK array.
+
+bb. Fixed a problem with quoted arguments to arithmetic expansions in certain
+ constructs.
+
+cc. The command word completion code now no longer returns matching directories
+ while searching $PATH.
+
+dd. Fixed a bug with zero-padding and precision handling in snprintf()
+ replacement.
+
+ee. Fixed a bug that caused the command substitution code not to take embedded
+ shell comments into account.
+
+ff. Fixed a bug that caused $((...);(...)) to be misinterpreted as an
+ arithmetic substitution.
+
+gg. Fixed a bug in the prompt expansion code that inappropriately added a
+ \001 before a \002 under certain circumstances.
+
+hh. Fixed a bug that caused `unset LANG' to not properly reset the locale
+ (previous versions would set the locale back to what it was when bash
+ was started rather than the system's "native" locale).
+
+ii. Fixed a bug that could cause file descriptors > 10 to not be closed even
+ when closed explicitly by a script.
+
+jj. Fixed a bug that caused single quotes to be stripped from ANSI-C quoting
+ inside double-quoted command substitutions.
+
+kk. Fixed a bug that could cause core dumps when `return' was executed as the
+ last element of a pipeline inside a shell function.
+
+ll. Fixed a bug that caused DEBUG trap strings to overwrite commands stored in
+ the jobs list.
+
+2. Changes to Readline
+
+a. Fixed a problem that caused segmentation faults when using readline in
+ callback mode and typing consecutive DEL characters on an empty line.
+
+b. Fixed several redisplay problems with multibyte characters, all having to
+ do with the different code paths and variable meanings between single-byte
+ and multibyte character redisplay.
+
+c. Fixed a problem with key sequence translation when presented with the
+ sequence \M-\C-x.
+
+d. Fixed a problem that prevented the `a' command in vi mode from being
+ undone and redone properly.
+
+e. Fixed a problem that prevented empty inserts in vi mode from being undone
+ properly.
+
+f. Fixed a problem that caused readline to initialize with an incorrect idea
+ of whether or not the terminal can autowrap.
+
+g. Fixed output of key bindings (like bash `bind -p') to honor the setting of
+ convert-meta and use \e where appropriate.
+
+h. Changed the default filename completion function to call the filename
+ dequoting function if the directory completion hook isn't set. This means
+ that any directory completion hooks need to dequote the directory name,
+ since application-specific hooks need to know how the word was quoted,
+ even if no other changes are made.
+
+i. Fixed a bug with creating the prompt for a non-interactive search string
+ when there are non-printing characters in the primary prompt.
+
+j. Fixed a bug that caused prompts with invisible characters to be redrawn
+ multiple times in a multibyte locale.
+
+k. Fixed a bug that could cause the key sequence scanning code to return the
+ wrong function.
+
+l. Fixed a problem with the callback interface that caused it to fail when
+ using multi-character keyboard macros.
+
+m. Fixed a bug that could cause a core dump when an edited history entry was
+ re-executed under certain conditions.
+
+n. Fixed a bug that caused readline to reference freed memory when attmpting
+ to display a portion of the prompt.
+
+3. New Features in Bash
+
+a. Changed the parameter pattern replacement functions to not anchor the
+ pattern at the beginning of the string if doing global replacement - that
+ combination doesn't make any sense.
+
+b. When running in `word expansion only' mode (--wordexp option), inhibit
+ process substitution.
+
+c. Loadable builtins now work on MacOS X 10.[34].
+
+d. Shells running in posix mode no longer set $HOME, as POSIX requires.
+
+e. The code that checks for binary files being executed as shell scripts now
+ checks only for NUL rather than any non-printing character.
+
+f. Quoting the string argument to the [[ command's =~ operator now forces
+ string matching, as with the other pattern-matching operators.
+
+4. New Features in Readline
+
+a. Calling applications can now set the keyboard timeout to 0, allowing
+ poll-like behavior.
+
+b. The value of SYS_INPUTRC (configurable at compilation time) is now used as
+ the default last-ditch startup file.
+
+c. The history file reading functions now allow windows-like \r\n line
+ terminators.
