 * Changes in Wget 1.9+.
 
-** Many options that previously unconditionally set or unset features
-are now boolean options that can be invoked as `--OPTION[=yes/no]' or
-with `--no-OPTION'.  This is useful because it allows you to specify
-non-default behavior via `.wgetrc' and then revert it again on the
-command-line.
+** IPv6 is now supported by Wget.  Unlike the experimental code in
+1.9, this version has no problems with dual-family systems.  The new
+flags `--inet4' and `--inet6' (or `-4' and `-6' for short) force the
+use of IPv4 and IPv6 respectively.
+
+** Talking to SSL servers over proxies now actually works.
+
+** Wget no longer truncates partially downloaded files when download
+has to start over because the server doesn't support Range.  Instead,
+with such servers Wget now simply ignores the data up to the byte
+where the last attempt left off, and only then continues appending to
+the file.  That way the downloaded file never shrinks, and "start
+over" retries work correctly even when downloading to stdout.
+
+** The `--header' option can now be used to override generated
+headers.  For example, `wget --header="Host: foo.bar"
+http://127.0.0.1' tells Wget to connect to localhost, but to specify
+"foo.bar" in the `Host' header.  In previous versions such use of
+`--header' lead to duplicate headers in HTTP requests.
+
+** The responses without headers, aka "HTTP 0.9" responses, are
+detected and handled.  Although HTTP 0.9 has long been obsolete, it is
+still occasionally used, sometimes by accident.
+
+** The progress bar is now updated regularly even when the data does
+not arrive from the network.
+
+** Wget no longer preserves permissions of files retrieved by FTP by
+default.  Anonymous FTP servers frequently use permissions like "664",
+which might not be what the user wants.  The new option
+`--preserve-permissions' and the corresponding `.wgetrc' variable can
+be used to revert to the old behavior.
+
+** The new option `--protocol-directories' instructs Wget to also use
+the protocol name as a directory component of local file names.
+
+** Many options that previously unconditionally set or unset various
+flags are now boolean options that can be invoked as either `--OPTION'
+or `--no-OPTION'.  Options that required an argument "on" or "off"
+have also been changed this way, but they still accept the old syntax
+for backward compatibility.  For example, instead of `--glob=off' you
+can write `--no-glob'.
+
+Allowing `--no-OPTION' for every `--OPTION' is useful because it
+allows the user to override non-default behavior specified via
+`.wgetrc'.

 save session cookies along with the permanent ones.  This is useful on
