+
+u. Fixed a bug that could result in command substitution, when executed in a

+
+v. Fixed a bug that could cause history expansion to be disabled in a non-

+    pointer to not be reset when read(2) returned an EOF.
+
+dd. Bash now installs its SIGWINCH signal handler with SA_RESTART, so it will
+    not interrupt open/read/write system calls.
+
+ee. The ERR trap now reports line numbers more reliably.
+
+ff. The shell no longer tries to manipulate the terminal process group if a
+    command or process substitution is killed by SIGTERM when job control is
+    enabled.
+
+gg. Fixed a bug that caused extglob patterns to match filenames beginning with

+
+nn. Restricted shells now clear the hash table before making the PATH variable
+    read-only.
+
+oo. There are a number of changes to the expansion of $* and $@ in contexts
+    where word splitting does not occur (quoted and unquoted), with IFS set
+    to NULL or a non-standard value, mostly to deal with the consequences of
+    the behavior defined in Posix interpretation 888.
+
+pp. There are a number of changes to nameref variable handling to avoid
+    creating variables with invalid names.
+
+qq. A non-interactive posix mode shell no longer exits when an assignment
+    statement fails if the assignment is utimately being performed by the

+rr. When using character class names for globbing, don't allow case
+    insensitivity, even if nocaseglob is enabled.
+
+ss. Fixed a bug that allowed some redirections to stay in place if a later

+
+tt. Fixed a bug in how command and process substitutions are recognized within
+    other parameter expansions.
+
+uu. Fixed a bug that caused bash to loop under certain circumstances when
+    performing arithmetic expansion on a variable whose value is an invalid
+    expression.
+
+vv. Fixed a bug that could cause bash to expand aliases inappropriately while
+    parsing compound commands like `case'.
+
+ww. Fixed a bug that could cause `read -N' to fail to read complete multibyte
+    characters, even when the sequences are incomplete or invalid, with or
+    without readline.
+
+xx. Fixed a bug that could cause `case' to fail to match patterns containing
+    0x01 characters.
+
+yy. Fixed a bug that caused exported functions to contain stray 0x01 characters.
+
+zz. Fixed some inconsistencies with how the history number is handled in the
+    various prompt strings.
+
+aaa. Fixed a bug that could cause a core dump if READLINE_LINE was unset

+
+bbb. Fixed a bug that could cause bash to not read a token terminator correctly
+     if a command substitution was used inside an arithmetic `for' command.
+
+ccc. Fixed problems that could occur with a fatal arithmetic expansion error
+     in a context (like prompt expansion) where you can't jump back to the
+     top level.
+
+ddd. Expression errors in arithmetic `for' commands are treated more like
+     shell syntax errors.
+
+eee. Fixed a parser synchronization error resulting from a syntax error
+     followed immediately by an EOF.
+
+fff. When executing a shell function, the first line in the function ($LINENO)
+     is line 1 instead of line 0, as Posix requires.
+
+ggg. In Posix mode, bash will canonicalize the value of PWD it inherits from
+     the environment and use that to set its idea of the current directory.
+
+hhh. If LINENO is exported, bash needs to regenerate its value each time it
+     constructs the environment.
+
+iii. Fixed a bug with restoring the SIGINT handler when using `wait -n'.

+kkk. Fixed a problem with arithmetic expressions containing array references
+     that contain arithmetic expressions with syntax errors.

+     size returned from the kernel as the terminal width.
+
+mmm. `read -n 0' and `read -N 0' now try a zero-length read in an attempt to
+     detect file descriptor errors.
+
+nnn. The `read' builtin now does a better job of acting on signals that don't
+     interrupt read(2).
+
+ooo. Fixed some cases where `printf -v' did not return failure status on a
+     variable assignment error.
+
+ppp. Fixed temporary environment propagation back to the current environment
+     so that it doesn't happen for special builtins run by the `command'
+     builtin.
+
+qqq. Fixed a bug when searching for the end of a here-document delimiter in a
+     command substitution.
+
+rrr. Fixed a bug that could cause `cd ${DIRSTACK[0]}' to fail.
+
+sss. Fixed a bug that could cause reserved words to not be recognized in a
+     for statement without the `in' inside a command substitution.
+
+ttt. Fixed a bug that could cause a double-free in a timed command with an
+     expansion error.
+
+uuu. Fixed a bug that could cause a core dump if a script switches from a UTF-8
+     locale to a different locale after displaying a lone surrogate character.
+
+vvv. Fixed cases where bash prematurely removed FIFOs attached to process
+     substitutions.
+
+www. Fixed a problem with calculating the size of the table that stores exit
+     statuses from background processes when the child process resource limit
+     is very large.
+
+xxx. Fixed a memory leak with functions using `return' when using FIFOs for
+     standard input.
+
+yyy. `wait' without arguments attempts to wait for all active process
+     substitution processes.
+
+zzz. Fixed a bug where an indirect parameter was subjected to word splitting
+     when trying to find the indirected variable name.
+
+aaaa. Fixed a bug that could allow restricted shell users to add commands to
+      the hash table.
+
+bbbb. When using the `!(patlist)' extended globbing operator, a filename
+      beginning with a `.' that doesn't match any of the patterns is not
+      returned as a match if leading dots must be matched explicitly.
+
+cccc. Fixed a bug that could cause line number and source file information for
+      a function definition to be incorrect if there are multiple definitions.
+
+dddd. Fixed a bug that could cause builtins like `readonly' to behave
+      differently when applied to arrays and scalar variables within functions.
+
+eeee. Fixed a bug that could cause alias expansion to add an extra space to
+      a quoted string that begins outside the alias expansion.
+
+ffff. Fixed a bug that could result in unwanted alias expansion after timing
+      the null command.
+
+gggg. Fixed a bug that could cause a core dump if a timestamp in a history
+      file overflowed a time_t.
+
+hhhh. Restricted shells can no longer redirect from /dev/tcp or /dev/udp, since
+      the kernel calls make those file descriptors read-write.
+
+iiii. Fixed a problem with splitting double-quoted words for programmable
+      completion when the double quote immediately follows another word
+      delimiter.
+
+jjjj. Fixed a bug resulting in a use-after-free if two file descriptors share
+      the same input buffer.
+
+kkkk. The error message resulting from ${x:?} and ${x?} now differs depending
+      on whether the variable is null or unset.
+
+llll. In Posix mode, the shell exits if a variable assignment fails and precedes
+      an empty simple command (after expansion).
+
+mmmm. Fixed a timing problem with SIGALRM that could cause the read builtin to
+      drop characters.
+
+nnnn. Added code to deal with kill(2) failing to send the shell a fatal signal
+      due to Linux pid namespace peculiarities.
+
+oooo. Fixed a bug that made \C-@ (NUL) unusable in key sequences used for
+      `bind -x' commands.
+
+pppp. Fixed a bug that could cause SIGINT recursion when running an external
+      command in a trap the shell takes after a command exits due to SIGINT.
+
+qqqq. Make sure the shell turns off job control before running the command-
+      not-found handle, so the command doesn't try to manipulate process
+      groups.
+
+rrrr. Fixed a problem with timing process substitutions that caused the shell
+      to print timing information for the calling command.
+
+ssss. Fixed a bug that caused backquotes in a here-document delimiter to mark
+      the delimiter as quoted (inhibiting expansion of the here-document
+      contents).
+
+tttt. Fixed several problems with 0x01 and 0x177 in case pattern lists and
+      conditional command pattern matches.
+
+uuuu. Fixed a bug that could cause the pattern matching engine to not recognize
+      locale-specific character classes.
+
+vvvv. The auto-configuration now tests for /dev/stdin and /dev/fd independently.
+
+wwww. The `globstar' code now skips over symbolic links to directories,
+      preventing them from being scanned twice.
+
+xxxx. When running `bind -x' commands, bash now sets READLINE_POINT based on
+      the number of characters in the readline line buffer, not the number of
+      bytes.
+
+yyyy. Fixed a problem that could cause recursive trap evaluation of the RETURN
+      trap when using `eval return'.
+
+zzzz. Fixed a bug with expanding 0x01 in an unquoted here-document.
+
+aaaaa. The process substitution code now closes and unlinks FIFOs when the
+       process on the other side exits, in order to prevent SIGPIPE or
+       waiting until a FIFO opened for read has a writer.
+
+bbbbb. Fixed a bug with recursive calls to the parser overwriting the token in
+       an {id}>foo construct.
+
+ccccc. After a Posix discussion, the pattern matching engine just skips over
+       invalid character classes in bracket expressions, instead of matching
+       them like individual characters in the expression.
+
+ddddd. Fixed a posix-mode problem with variable scoping when creating variables
+       from assignment statements preceding special builtins.
+
+eeeee. Fixed a bug that could cause patterns containing backslashes to not be
+       run through the pattern matching engine.
+
+fffff. Fixed a bug that could cause redirections to compound commands to not
+       be `undone' if the file descriptor in the redirection was closed when
+       the redirection was initially processed.
+
+ggggg. Fixed a bug that could cause buffer corruption when using `bind -x' in
+       a command execute as a result of a key binding installed by `bind -x'.
+
+2.  Changes to Readline
+
+a. Added a guard to prevent nested macros from causing an infinite expansion
+   loop.
+
+b. Instead of allocating enough history list entries to hold the maximum list
+   size, cap the number allocated initially.
+
+c. Added a strategy to avoid allocating huge amounts of memory if a block of
+   history entries without timestamps occurs after a block with timestamps.
+
+d. Added support for keyboard timeouts when an ESC character is the last
+   character in a macro.
+
+e. There are several performance improvements when in a UTF-8 locale.
+
+f. Readline does a better job of preserving the original set of blocked
+   signals when using pselect() to wait for input.
+
+g. Fixed a bug that caused multibyte characters in macros to be mishandled.
+
+h. Fixed several bugs in the code that calculates line breaks when expanding
+   prompts that span several lines, contain multibyte characters, and contain
+   invisible character seqeuences.
+
+i. Fixed several bugs in cursor positioning when displaying lines with prompts
+   containing invisible characters and multibyte characters.
+
+j. When performing case-insensitive completion, Readline no longer sorts the
+   list of matches unless directed to do so.
+
+k. Fixed a problem with key sequences ending with a backslash.
+
+l. Fixed out-of-bounds and free memory read errors found via fuzzing.
+
+m. Fixed several cases where the mark was set to an invalid value.
+
+n. Fixed a problem with the case-changing operators in the case where the
+   lower and upper case versions of a character do not have the same number
+   of bytes.
+
+o. Handle incremental and non-incremental search character reads returning EOF.
+
+p. Handle the case where a failing readline command at the end of a multi-key
+   sequence could be misinterpreted.
+
+q. The history library now prints a meaningful error message if the history
+   file isn't a regular file.
+
+r. Fixed a problem with vi-mode redo (`.') on a command when trying to replace
+   a multibyte character.
+
+s. The key binding code now attempts to remove a keymap if a key unbinding
+   leaves it empty.
+
+t. Fixed a line-wrapping issue that caused problems for some terminal
+   emulators.
+
+u. If there is a key bound to the tty's VDISCARD special character, readline
+   disables VDISCARD while it is active.
+
+v. Fixed a problem with exiting bracketed paste mode on terminals that assume
+   the bracketed paste mode character sequence contains visible characters.
+
+w. Fixed a bug that could cause a key binding command to refer to an
+   uninitialized variable.
+
+3.  New Features in Bash
+
+a. The `wait' builtin can now wait for the last process substitution created.
+
+b. There is an EPOCHSECONDS variable, which expands to the time in seconds
+   since the Unix epoch.
+
+c. There is an EPOCHREALTIME variable, which expands to the time in seconds
+   since the Unix epoch with microsecond granularity.
+
+d. New loadable builtins: rm, stat, fdflags.
+
+e. BASH_ARGV0: a new variable that expands to $0 and sets $0 on assignment.
+
+f. When supplied a numeric argument, the shell-expand-line bindable readline
+   command does not perform quote removal and suppresses command and process
+   substitution.
+
+g. `history -d' understands negative arguments: negative arguments offset from
+   the end of the history list.
+
+h. The `name' argument to the `coproc' reserved word now undergoes word
+   expansion, so unique coprocs can be created in loops.
+
+i. A nameref name resolution loop in a function now resolves to a variable by
+   that name in the global scope.
+
+j. The `wait' builtin now has a `-f' option, which signfies to wait until the
+   specified job or process terminates, instead of waiting until it changes
+   state.
+
+k. There is a define in config-top.h that allows the shell to use a static
+   value for $PATH, overriding whatever is in the environment at startup, for
+   use by the restricted shell.
+
+l. Process substitution does not inherit the `v' option, like command
+   substitution.
+
+m. If a non-interactive shell with job control enabled detects that a foreground
+   job died due to SIGINT, it acts as if it received the SIGINT.
+
+n. The SIGCHLD trap is run once for each exiting child process even if job
+   control is not enabled when the shell is in Posix mode.
+
+o. A new shopt option: localvar_inherit; if set, a local variable inherits the
+   value of a variable with the same name at the nearest preceding scope.
+
+p. `bind -r' now checks whether a key sequence is bound before binding it to
+   NULL, to avoid creating keymaps for a multi-key sequence.
+
+q. A numeric argument to the line editing `operate-and-get-next' command
+   specifies which history entry to use.
+
+r. The positional parameters are now assigned before running the shell startup
+   files, so startup files can use $@.
+
+s. There is a compile-time option that forces the shell to disable the check
+   for an inherited OLDPWD being a directory.
+
+t. The `history' builtin can now delete ranges of history entries using
+   `-d start-end'.
+
+u. The `vi-edit-and-execute-command' bindable readline command now puts readline
+   back in vi insertion mode after executing commands from the edited file.
+
+v. The command completion code now matches aliases and shell function names
+   case-insensitively if the readline completion-ignore-case variable is set.
+
+w. There is a new `assoc_expand_once' shell option that attempts to expand
+   associative array subscripts only once.
+
+x. The shell only sets up BASH_ARGV and BASH_ARGC at startup if extended
+   debugging mode is active. The old behavior of unconditionally setting them
+   is available as part of the shell compatibility options.
+
+y. The `umask' builtin now allows modes and masks greater than octal 777.
+
+z. The `times' builtin now honors the current locale when printing a decimal
+   point.
+
+aa. There is a new (disabled by default, undocumented) shell option to enable
+    and disable sending history to syslog at runtime.
+
+4.  New Features in Readline
+
+a. Non-incremental vi-mode search (`N', `n') can search for a shell pattern, as
+   Posix specifies (uses fnmatch(3) if available).
+
+b. There are new `next-screen-line' and `previous-screen-line' bindable
+   commands, which move the cursor to the same column in the next, or previous,
+   physical line, respectively.
+
+c. There are default key bindings for control-arrow-key key combinations.
+
+d. A negative argument (-N) to `quoted-insert' means to insert the next N
+   characters using quoted-insert.
+
+e. New public function: rl_check_signals(), which allows applications to
+   respond to signals that readline catches while waiting for input using
+   a custom read function.
+
+f. There is new support for conditionally testing the readline version in an
+   inputrc file, with a full set of arithmetic comparison operators available.
+
+g. There is a simple variable comparison facility available for use within an
+   inputrc file. Allowable operators are equality and inequality; string
+   variables may be compared to a value; boolean variables must be compared to
+   either `on' or `off'; variable names are separated from the operator by
+   whitespace.
