+This is a terse description of the new features added to bash-2.05a since
+the release of bash-2.05. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. Added support for DESTDIR installation root prefix, so you can do a
+ `make install DESTDIR=bash-root' and do easier binary packaging.
+
+b. Added support for builtin printf "'" flag character as per latest POSIX
+ drafts.
+
+c. Support for POSIX.2 printf(1) length specifiers `j', `t', and `z' (from
+ ISO C99).
+
+d. New autoconf macro, RL_LIB_READLINE_VERSION, for use by other applications
+ (bash doesn't use very much of what it returns).
+
+e. `set [-+]o nolog' is recognized as required by the latest POSIX drafts,
+ but ignored.
+
+f. New read-only `shopt' option: login_shell. Set to non-zero value if the
+ shell is a login shell.
+
+g. New `\A' prompt string escape sequence; expands to time in 24 HH:MM format.
+
+h. New `-A group/-g' option to complete and compgen; does group name
+ completion.
+
+i. New `-t' option to `hash' to list hash values for each filename argument.
+
+j. New [-+]O invocation option to set and unset `shopt' options at startup.
+
+k. configure's `--with-installed-readline' option now takes an optional
+ `=PATH' suffix to set the root of the tree where readline is installed
+ to PATH.
+
+l. The ksh-like `ERR' trap has been added. The `ERR' trap will be run
+ whenever the shell would have exited if the -e option were enabled.
+ It is not inherited by shell functions.
+
+m. `readonly', `export', and `declare' now print variables which have been
+ given attributes but not set by assigning a value as just a command and
+ a variable name (like `export foo') when listing, as the latest POSIX
+ drafts require.
+
+n. `bashbug' now requires that the subject be changed from the default.
+
+o. configure has a new `--enable-largefile' option, like other GNU utilities.
+
+p. `for' loops now allow empty word lists after `in', like the latest POSIX
+ drafts require.
+
+q. The builtin `ulimit' now takes two new non-numeric arguments: `hard',
+ meaning the current hard limit, and `soft', meaning the current soft
+ limit, in addition to `unlimited'
+
+r. `ulimit' now prints the option letter associated with a particular
+ resource when printing more than one limit.
+
+s. `ulimit' prints `hard' or `soft' when a value is not `unlimited' but is
+ one of RLIM_SAVED_MAX or RLIM_SAVED_CUR, respectively.
+
+t. The `printf' builtin now handles the %a and %A conversions if they're
+ implemented by printf(3).
+
+u. The `printf' builtin now handles the %F conversion (just about like %f).
+
+v. The `printf' builtin now handles the %n conversion like printf(3). The
+ corresponding argument is the name of a shell variable to which the
+ value is assigned.
+
+2. New Features in Readline
+
+a. Added extern declaration for rl_get_termcap to readline.h, making it a
+ public function (it was always there, just not in readline.h).
+
+b. New #defines in readline.h: RL_READLINE_VERSION, currently 0x0402,
+ RL_VERSION_MAJOR, currently 4, and RL_VERSION_MINOR, currently 2.
+
+c. New readline variable: rl_readline_version, mirrors RL_READLINE_VERSION.
+
+d. New bindable boolean readline variable: match-hidden-files. Controls
+ completion of files beginning with a `.' (on Unix). Enabled by default.
+
+e. The history expansion code now allows any character to terminate a
+ `:first-' modifier, like csh.
+
+f. New bindable variable `history-preserve-point'. If set, the history
+ code attempts to place the user at the same location on each history
+ line retrived with previous-history or next-history.

synopsis.
f. There are several new arithmetic operators: id++, id-- (variable
- post-increment/decrement), ++id, --id (variabl pre-increment/decrement),
+ post-increment/decrement), ++id, --id (variable pre-increment/decrement),
expr1 , expr2 (comma operator).
g. There is a new ksh-93 style arithmetic for command:
