6 Please send GNU Wget bug reports to <bug-wget@gnu.org>.
8 * Changes in Wget 1.9+.
10 ** IPv6 is now supported by Wget. Unlike the experimental code in
11 1.9, this version has no problems with dual-family systems. The new
12 flags `--inet4' and `--inet6' (or `-4' and `-6' for short) force the
13 use of IPv4 and IPv6 respectively.
15 ** Talking to SSL servers over proxies now actually works.
17 ** Wget no longer truncates partially downloaded files when download
18 has to start over because the server doesn't support Range. Instead,
19 with such servers Wget now simply ignores the data up to the byte
20 where the last attempt left off, and only then continues appending to
21 the file. That way the downloaded file never shrinks, and "start
22 over" retries work correctly even when downloading to stdout.
24 ** The `--header' option can now be used to override generated
25 headers. For example, `wget --header="Host: foo.bar"
26 http://127.0.0.1' tells Wget to connect to localhost, but to specify
27 "foo.bar" in the `Host' header. In previous versions such use of
28 `--header' lead to duplicate headers in HTTP requests.
30 ** The responses without headers, aka "HTTP 0.9" responses, are
31 detected and handled. Although HTTP 0.9 has long been obsolete, it is
32 still occasionally used, sometimes by accident.
34 ** The progress bar is now updated regularly even when the data does
35 not arrive from the network.
37 ** Wget no longer preserves permissions of files retrieved by FTP by
38 default. Anonymous FTP servers frequently use permissions like "664",
39 which might not be what the user wants. The new option
40 `--preserve-permissions' and the corresponding `.wgetrc' variable can
41 be used to revert to the old behavior.
43 ** The new option `--protocol-directories' instructs Wget to also use
44 the protocol name as a directory component of local file names.
46 ** Many options that previously unconditionally set or unset various
47 flags are now boolean options that can be invoked as either `--OPTION'
48 or `--no-OPTION'. Options that required an argument "on" or "off"
49 have also been changed this way, but they still accept the old syntax
50 for backward compatibility. For example, instead of `--glob=off' you
51 can write `--no-glob'.
53 Allowing `--no-OPTION' for every `--OPTION' is useful because it
54 allows the user to override non-default behavior specified via
57 ** The new option `--keep-session-cookies' causes `--save-cookies' to
58 save session cookies along with the permanent ones. This is useful on
59 sites that require you to log in before you can access some pages.
60 With this option, multiple Wget runs will be treated as a single
63 * `wget -b' now works correctly under Windows.
65 * Wget 1.9.1 is a bugfix release with no user-visible changes.
67 * Changes in Wget 1.9.
69 ** It is now possible to specify that POST method be used for HTTP
70 requests. For example, `wget --post-data="id=foo&data=bar" URL' will
71 send a POST request with the specified contents.
73 ** IPv6 support is available, although it's still experimental.
75 ** The `--timeout' option now also affects DNS lookup and establishing
76 the TCP connection. Previously it only affected reading and writing
77 data. Those three timeouts can be set separately using
78 `--dns-timeout', `--connection-timeout', and `--read-timeout',
81 ** Download speed shown by the progress bar is based on the data
82 recently read, rather than the average speed of the entire download.
83 The ETA projection is still based on the overall average.
85 ** It is now possible to connect to FTP servers through FWTK
86 firewalls. Set ftp_proxy to an FTP URL, and Wget will automatically
87 log on to the proxy as "username@host".
89 ** The new option `--retry-connrefused' makes Wget retry downloads
90 even in the face of refused connections, which are otherwise
91 considered a fatal error.
93 ** The new option `--dns-cache=off' may be used to prevent Wget from
96 ** Wget no longer escapes characters in local file names based on
97 whether they're appropriate in URLs. Escaping can still occur for
98 nonprintable characters or for '/', but no longer for frequent
99 characters such as space. You can use the new option
100 --restrict-file-names to relax or strengthen these rules, which can be
101 useful if you dislike the default or if you're downloading to
102 non-native partitions.
104 ** Handling of HTML comments has been dumbed down to conform to what
105 users expect and other browsers do: instead of being treated as SGML
106 declaration, a comment is terminated at the first occurrence of "-->".
107 Use `--strict-comments' to revert to the old behavior.
109 ** Wget now correctly handles relative URIs that begin with "//", such
110 as "//img.foo.com/foo.jpg".
112 ** Boolean options in `.wgetrc' and on the command line now accept
113 values "yes" and "no" along with the traditional "on" and "off".
115 ** It is now possible to specify decimal values for timeouts, waiting
116 periods, and download rate. For instance, `--wait=0.5' now works as
117 expected, as does `--dns-timeout=0.5' and even `--limit-rate=2.5k'.
119 * Wget 1.8.2 is a bugfix release with no user-visible changes.
121 * Wget 1.8.1 is a bugfix release with no user-visible changes.
123 * Changes in Wget 1.8.
125 ** A new progress indicator is now available and used by default.
126 You can choose the progress bar type with `--progress=TYPE'. Two
127 types are available, "bar" (the new default), and "dot" (the old
128 dotted indicator). You can permanently revert to the old progress
129 indicator by putting `progress = dot' in your `.wgetrc'.
131 ** You can limit the download rate of the retrieval using the
132 `--limit-rate' option. For example, `wget --limit-rate=15k URL' will
133 tell Wget not to download the body of the URL faster than 15 kilobytes
136 ** Recursive retrieval and link conversion have been revamped:
138 *** Wget now traverses links breadth-first. This makes the
139 calculation of depth much more reliable than before. Also, recursive
140 downloads are faster and consume *significantly* less memory than
143 *** Links are converted only when the entire retrieval is complete.
144 This is the only safe thing to do, as only then is it known what URLs
145 have been downloaded.
147 *** BASE tags are handled correctly when converting links. Since Wget
148 already resolves <base href="..."> when resolving handling URLs, link
149 conversion now makes the BASE tags point to an empty string.
151 *** HTML anchors are now handled correctly. Links to an anchor in the
152 same document (<a href="#anchorname">), which used to confuse Wget,
153 are now converted correctly.
155 *** When in page-requisites (-p) mode, no-parent (-np) is ignored when
156 retrieving for inline images, stylesheets, and other documents needed
159 *** Page-requisites (-p) mode now works with frames. In other words,
160 `wget -p URL-THAT-USES-FRAMES' will now download the frame HTML files,
161 and all the files that they need to be displayed properly.
163 ** `--base' now works conjunction with `--input-file', providing a
164 base for each URL and thereby allowing the URLs in the file to be
167 ** If a host has more than one IP address, Wget uses the other
168 addresses when accessing the first one fails.
170 ** Host directories now contain port information if the URL is at a
173 ** Wget now supports the robots.txt directives specified in
174 <http://www.robotstxt.org/wc/norobots-rfc.txt>.
176 ** URL parser has been fixed, especially the infamous overzealous
177 quoting. Wget no longer dequotes reserved characters, e.g. `%3F' is
178 no longer translated to `?', nor `%2B' to `+'. Unsafe characters
179 which are not reserved are still escaped, of course.
181 ** No more than 20 successive redirections are allowed.
183 * Wget 1.7.1 is a bugfix release with no user-visible changes.
185 * Changes in Wget 1.7.
187 ** SSL (`https') pages now work if you compile Wget with SSL support;
188 use the `--with-ssl' configure flag. You need to have OpenSSL
191 ** Cookies are now supported. Wget will accept cookies sent by the
192 server and return them in later requests. Additionally, it can load
193 and save cookies to disk, in the same format that Netscape uses.
195 ** "Keep-alive" (persistent) HTTP connections are now supported.
196 Using keep-alive allows Wget to share one TCP/IP connection for
197 many retrievals, making multiple-file downloads faster and less
198 stressing for the server and the network.
200 ** Wget now recognizes FTP directory listings generated by NT and VMS
203 ** It is now possible to recurse through FTP sites where logging in
204 puts you in some directory other than '/'.
206 ** You may now use `~' to mean home directory in `.wgetrc'. For
207 example, `load_cookies = ~/.netscape/cookies.txt' works as you would
210 ** The HTML parser has been rewritten. The new one works more
211 reliably, allows finer-grained control over which tags and attributes
212 are detected, and has better support for some features like correctly
213 skipping comments and declarations, decoding entities, etc. It is
216 ** <meta name="robots"> tags are now respected.
218 ** Wget's internal tables now use hash tables instead of linked lists
219 where appropriate. This results in huge speedups when retrieving
220 large sites (thousands of documents).
222 ** Wget now has a man page, automatically generated from the Texinfo
223 documentation. (The last version that shipped with a man page was
224 1.4.5). To get this, you need to have pod2man from the Perl
225 distribution installed on your system.
227 * Changes in Wget 1.6
229 ** Administrative changes.
231 *** Maintainership. Due to Hrvoje being plagued with a "real job",
232 Dan Harkless is the most active maintainer (not that he doesn't have a
233 real job as well). Hrvoje still participates occasionally, and both
234 are being helped by many other people.
236 *** Web page. Thanks to Jan Prikryl, Wget has an "official" web page.
239 http://sunsite.dk/wget/
241 *** Anonymous CVS. Thanks to ever-helpful Karsten Thygesen, Wget
242 sources are now available at an anonymous CVS server. Take a look at
243 the web page for downloading instructions.
245 ** New -K / --backup-converted / backup_converted = on option causes files
246 modified due to -k to be saved with a .orig prefix before being changed. When
247 using -N as well, it is these .orig files that are compared against the server.
249 ** New --follow-tags / follow_tags = ... option allows you to restrict
250 Wget to following only certain HTML tags when doing a recursive
251 retrieval. -G / --ignore-tags / ignore_tags = ... is just the
252 opposite -- all tags but the ones you specify will be followed.
254 ** New --waitretry / waitretry = SECONDS option allows waiting between retries
255 of failed downloads. Wget will use "linear" backoff, waiting 1 second after the
256 first failure, 2 after the second, up to SECONDS. waitretry is set to 10 by
257 default in the system wgetrc.
259 ** New -p / --page-requisites / page_requisites = on option causes
260 Wget to download all ancillary files necessary to display a given HTML
261 page properly (e.g. inlined images).
263 ** New -E / --html-extension / html_extension = on option causes Wget
264 to append ".html" to text/html filenames not ending in regexp
265 "\.[Hh][Tt][Mm][Ll]?".
267 ** New type of .wgetrc command -- "lockable Boolean". Can be set to on, off,
268 always, or never. This allows the .wgetrc to override the commandline. So far,
269 passive_ftp is the only .wgetrc command which takes a lockable Boolean.
271 ** A number of new translation files have been added.
273 ** New --bind-address / bind_address = <address> option for people on hosts
274 bound to multiple IP addresses.
276 ** wget now accepts (illegal per HTTP spec) relative URLs in HTTP redirects.
278 * Wget 1.5.3 is a bugfix release with no user-visible changes.
280 * Wget 1.5.2 is a bugfix release with no user-visible changes.
282 * Wget 1.5.1 is a bugfix release with no user-visible changes.
284 * Changes in Wget 1.5.0
286 ** Wget speaks many languages!
288 On systems with gettext(), Wget will output messages in the language
289 set by the current locale, if available. At this time we support
290 Czech, German, Croatian, Italian, Norwegian and Portuguese.
292 ** Opie (Skey) is now supported with FTP.
294 ** HTTP Digest Access Authentication (RFC2069) is now supported.
296 ** The new `-b' option makes Wget go to background automatically.
298 ** The `-I' and `-X' options now accept wildcard arguments.
300 ** The `-w' option now accepts suffixes `s' for seconds, `m' for
301 minutes, `h' for hours, `d' for days and `w' for weeks.
303 ** Upon getting SIGHUP, the whole previous log is now copied to
306 ** Wget now understands proxy settings with explicit usernames and
307 passwords, e.g. `http://user:password@proxy.foo.com/'.
309 ** You can use the new `--cut-dirs' option to make Wget create less
312 ** The `;type=a' appendix to FTP URLs is now recognized. For
313 instance, the following command will retrieve the welcoming message in
316 wget "ftp://ftp.somewhere.com/welcome.msg;type=a"
318 ** `--help' and `--version' options have been redone to to conform to
319 standards set by other GNU utilities.
321 ** Wget should now be compilable under MS Windows environment. MS
322 Visual C++ and Watcom C have been used successfully.
324 ** If the file length is known, percentages are displayed during
327 ** The manual page, now hopelessly out of date, is no longer
328 distributed with Wget.
330 * Wget 1.4.5 is a bugfix release with no user-visible changes.
332 * Wget 1.4.4 is a bugfix release with no user-visible changes.
334 * Changes in Wget 1.4.3
336 ** Wget is now a GNU utility.
338 ** Can do passive FTP.
342 ** Info documentation expanded.
344 ** Compiles on pre-ANSI compilers.
346 ** Global wgetrc now goes to /usr/local/etc (i.e. $sysconfdir).
350 * Changes in Wget 1.4.2
352 ** New mirror site at ftp://sunsite.auc.dk/pub/infosystems/wget/,
353 thanks to Karsten Thygesen.
355 ** Mailing list! Mail to wget-request@sunsite.auc.dk to subscribe.
357 ** New option --delete-after for proxy prefetching.
359 ** New option --retr-symlinks to retrieve symbolic links like plain
362 ** rmold.pl -- script to remove files deleted on the remote server
364 ** --convert-links should work now.
368 * Changes in Wget 1.4.1
372 ** Added -I (the opposite of -X).
374 ** Dot tracing is now customizable; try wget --dot-style=binary
376 * Changes in Wget 1.4.0
378 ** Wget 1.4.0 [formerly known as Geturl] is an extensive rewrite of
379 Geturl. Although many things look suspiciously similar, most of the
380 stuff was rewritten, like recursive retrieval, HTTP, FTP and mostly
381 everything else. Wget should be now easier to debug, maintain and,
382 most importantly, use.
384 ** Recursive HTTP should now work without glitches, even with Location
385 changes, server-generated directory listings and other naughty stuff.
387 ** HTTP regetting is supported on servers that support Range
388 specification. WWW authorization is supported -- try
389 wget http://user:password@hostname/
391 ** FTP support was rewritten and widely enhanced. Globbing should now
392 work flawlessly. Symbolic links are created locally. All the
393 information the Unix-style ls listing can give is now recognized.
395 ** Recursive FTP is supported, e.g.
396 wget -r ftp://gnjilux.cc.fer.hr/pub/unix/util/
398 ** You can specify "rejected" directories, to which you do not want to
399 enter, e.g. with wget -X /pub
401 ** Time-stamping is supported, with both HTTP and FTP. Try wget -N URL.
403 ** A new texinfo reference manual is provided. It can be read with
404 Emacs, standalone info, or converted to HTML, dvi or postscript.
406 ** Fixed a long-standing bug, so that Wget now works over SLIP
409 ** You can have a system-wide wgetrc (/usr/local/lib/wgetrc by
410 default). Settings in $HOME/.wgetrc override the global ones, of
413 ** You can set up quota in .wgetrc to prevent sucking too much
414 data. Try `quota = 5M' in .wgetrc (or quota = 100K if you want your
415 sysadmin to like you).
417 ** Download rate is printed after retrieval.
419 ** Wget now sends the `Referer' header when retrieving
422 ** With the new --no-parent option Wget can retrieve FTP recursively
423 through a proxy server.
425 ** HTML parser, as well as the whole of Wget was rewritten to be much
426 faster and less memory-consuming (yes, both).
428 ** Absolute links can be converted to relative links locally. Check
431 ** Wget catches hangup, filtering the output to a log file and
432 resuming work. Try kill -HUP %?wget.
434 ** User-defined headers can be sent. Try
436 wget http://fly.cc.her.hr/ --header='Accept-Charset: iso-8859-2'
438 ** Acceptance/Rejection lists may contain wildcards.
440 ** Wget can display HTTP headers and/or FTP server response with the
441 new `-S' option. It can save the original HTTP headers with `-s'.
443 ** socks library is now supported (thanks to Antonio Rosella
444 <Antonio.Rosella@agip.it>). Configure with --with-socks.
446 ** There is a nicer display of REST-ed output.
448 ** Many new options (like -x to force directory hierarchy, or -m to
449 turn on mirroring options).
451 ** Wget is now distributed under GNU General Public License (GPL).
453 ** Lots of small features I can't remember. :-)
455 ** A host of bugfixes.
457 * Changes in Geturl 1.3
459 ** Added FTP globbing support (ftp://fly.cc.fer.hr/*)
461 ** Added support for no_proxy
463 ** Added support for ftp://user:password@host/
465 ** Added support for %xx in URL syntax
467 ** More natural command-line options
469 ** Added -e switch to execute .geturlrc commands from the command-line
471 ** Added support for robots.txt
473 ** Fixed some minor bugs
475 * Geturl 1.2 is a bugfix release with no user-visible changes.
477 * Changes in Geturl 1.1
479 ** REST supported in FTP
481 ** Proxy servers supported
483 ** GNU getopt used, which enables command-line arguments to be ordered
484 as you wish, e.g. geturl http://fly.cc.fer.hr/ -vo log is the same as
485 geturl -vo log http://fly.cc.fer.hr/
487 ** Netscape-compatible URL syntax for HTTP supported: host[:port]/dir/file
489 ** NcFTP-compatible colon URL syntax for FTP supported: host:/dir/file
491 ** <base href="xxx"> supported
493 ** autoconf supported
