7 Please send GNU Wget bug reports to <bug-wget@gnu.org>.
9 * Changes in Wget (MAINLINE).
11 ** Gnulib's getpass-gnu module is used to prompt for passwords.
13 ** Gnulib is now used to provide code for certain portability aspects in
16 ** Wget uses Automake now as part of its build infrastructure.
18 * Changes in Wget 1.11.1.
20 ** Interrupted downloads no longer result in renaming the file
21 (regression in 1.11 over 1.10.2).
23 ** Progress bar now displays correctly in non-English locales (and a
24 related assertion failure was fixed).
26 ** Wget no longer issues a GET request over HTTP for files it should
27 know it's not going to download (regression in 1.11 over 1.10.2).
29 ** Added option --auth-no-challenge, to support broken pre-1.11
30 authentication-before-server-challenge, which turns out to still be
31 useful for some limited cases.
33 ** Documentation of accept/reject lists in the manual's "Types of
34 Files" section now explains various aspects of their behavior that may
35 be surprising, and notes that they may change in the future.
37 ** Documentation of --no-parents now explains how a trailing slash, or
38 lack thereof, in the specified URL, will affect behavior.
40 * Changes in Wget 1.11.
42 ** Timestamping now uses the value from the most recent HTTP response,
43 rather than the first one it got.
45 ** Authentication information is no longer sent as part of the Referer
46 header in recursive fetches.
48 ** No authentication credentials are sent until a challenge is issued,
49 for improved security. Authentication handling is still not
50 RFC-compliant, as once a Basic challenge has been received, it will
51 assume it can send credentials to any URL at that same host, and not
52 just the ones at or below the original authenticated location.
53 Credentials for Digest authentication are still never saved or issued
54 automatically, and continue to require a challenge for each resource.
56 ** Added --max-redirect option, allowing the user to specify what should
57 be the maximum number of HTTP redirects to follow.
59 ** Wget now supports saving HTTP downloads using file names specified by
60 the `Content-Disposition' header. This is a standard way of specifying
61 the file name used by many web dynamically generated pages. However, the
62 current implementation is inefficient, and known to have bugs. It is
63 EXPERIMENTAL only, and not enabled by default. Use --content-disposition
66 ** The new option `--ignore-case' makes Wget ignore case when
67 matching files, directories, and wildcards. This affects the -X, -I,
68 -A, and -R options, as well as globbing in FTP URLs.
70 ** ETA projection is now displayed in "dot" progress output as well as
71 in the default progress bar. (The dot progress is used by default when
72 logging Wget's output to file using the `-o' option.)
74 ** The "lockable boolean" argument type is no longer supported. It
75 was only used by the passive_ftp .wgetrc setting. If you're running
76 broken scripts or Perl modules that unconditionally specify
77 `--passive-ftp' and your firewall disallows it, you can override them
78 by replacing wget with a script that execs wget "$@" --no-passive-ftp.
80 ** The source code has been migrated to Mercurial. The repositories are
81 available at http://hg.addictivecode.org/. Prior to this, the source
82 code was hosted on Subversion (migrated from the original CVS); you can
83 still get access to older tags and branches for Wget in the Subversion
84 repository at http://addictivecode.org/svn/wget/.
86 * Changes in Wget 1.10.
88 ** Downloading files larger than 2GB, sometimes referred to as "large
89 files", now works on systems that support them. This includes the
90 majority of modern Unixes, as well as MS Windows.
92 ** IPv6 is now supported by Wget. Unlike the experimental code in
93 1.9, this version supports dual-family systems. The new flags
94 `--inet4' and `--inet6' (or `-4' and `-6' for short) force the use of
95 IPv4 and IPv6 respectively. Note that IPv6 support has not yet been
98 ** Microsoft's proprietary "NTLM" method of HTTP authentication is now
99 supported. This authentication method is undocumented and only used
100 by IIS. Note that *proxy* authentication is not supported in this
101 release; you can only authenticate to the target web site.
103 ** Wget no longer truncates partially downloaded files when download
104 has to start over because the server doesn't support Range. Instead,
105 with such servers Wget now simply ignores the data up to the byte
106 where the last attempt left off, and only then continues appending to
107 the file. That way the downloaded file never shrinks, and download
108 retries from servers without support for partial downloads work even
109 when downloading to stdout.
113 *** SSL/TLS downloads now attempt to verify the server's certificate
114 against the recognized certificate authorities. This requires CA
115 certificates to have been installed in a location visible to the
116 OpenSSL library. If this is not the case, you can get the bundle
117 yourself from a source you trust (for example, the bundle extracted
118 from Mozilla available at http://curl.haxx.se/docs/caextract.html),
119 and point Wget to the PEM file using the `--ca-certificate'
120 command-line option or the corresponding `.wgetrc' command.
122 *** Secure downloads now verify that the host name in the URL matches
123 the "common name" in the certificate presented by the server.
125 *** Although the above checks provide more secure downloads, they
126 unavoidably break interoperability with some sites that worked with
127 previous versions, particularly those using self-signed, expired, or
128 otherwise invalid certificates. If you encounter "certificate
129 verification" errors or complaints that "common name doesn't match
130 requested host name" and are convinced of the site's authenticity, you
131 can use `--no-check-certificate' to bypass both checks.
133 *** Talking to SSL/TLS servers over proxies now actually works.
134 Previous versions of Wget erroneously sent GET requests for https
135 URLs. Wget 1.10 utilizes the CONNECT method designed for this
138 *** The SSL/TLS-related options have been redesigned and, for the
139 first time, documented in the manual. The old, undocumented, options
140 are no longer supported.
142 ** Passive FTP is now the default FTP transfer mode. Use
143 `--no-passive-ftp' or specify `passive_ftp = off' in your init file to
144 revert to the old behavior.
146 ** The `--header' option can now be used to override generated
147 headers. For example, `wget --header="Host: foo.bar"
148 http://127.0.0.1' tells Wget to connect to localhost, but to specify
149 "foo.bar" in the `Host' header. In previous versions such use of
150 `--header' lead to duplicate headers in HTTP requests.
152 ** The responses without headers, aka "HTTP 0.9" responses, are
153 detected and handled. Although HTTP 0.9 has long been obsolete, it is
154 still occasionally used, sometimes by accident.
156 ** The progress bar is now updated regularly even when the data does
157 not arrive from the network.
159 ** Wget no longer preserves permissions of files retrieved by FTP by
160 default. Anonymous FTP servers frequently use permissions like "664",
161 which might not be what the user wants. The new option
162 `--preserve-permissions' and the corresponding `.wgetrc' variable can
163 be used to revert to the old behavior.
165 ** The new option `--protocol-directories' instructs Wget to also use
166 the protocol name as a directory component of local file names.
168 ** Options that previously unconditionally set or unset various flags
169 are now boolean options that can be invoked as either `--OPTION' or
170 `--no-OPTION'. Options that required an argument "on" or "off" have
171 also been changed this way, but they still accept the old syntax for
172 backward compatibility. For example, instead of `--glob=off' you can
175 Allowing `--no-OPTION' for every `--OPTION' and the other way around
176 is useful because it allows the user to override non-default behavior
177 specified via `.wgetrc'.
179 ** The new option `--keep-session-cookies' causes `--save-cookies' to
180 save session cookies (normally only kept in memory) along with the
181 permanent ones. This is useful because many sites track important
182 information, such as whether the user has authenticated, in session
183 cookies. With this option multiple Wget runs are treated as a single
186 ** Wget now supports the --ftp-user and --ftp-password command
187 switches to set username and password for FTP, and the --user and
188 --password command switches to set username and password for both FTP
189 and HTTP. The --http-passwd and --proxy-passwd command switches have
190 been renamed to --http-password and --proxy-password respectively, and
191 the related http_passwd and proxy_passwd .wgetrc commands to
192 http_password and proxy_password respectively. The login and passwd
193 .wgetrc commands have been deprecated.
195 * `wget -b' now works correctly under Windows.
197 * Wget 1.9.1 is a bugfix release with no user-visible changes.
199 * Changes in Wget 1.9.
201 ** It is now possible to specify that POST method be used for HTTP
202 requests. For example, `wget --post-data="id=foo&data=bar" URL' will
203 send a POST request with the specified contents.
205 ** IPv6 support is available, although it's still experimental.
207 ** The `--timeout' option now also affects DNS lookup and establishing
208 the TCP connection. Previously it only affected reading and writing
209 data. Those three timeouts can be set separately using
210 `--dns-timeout', `--connection-timeout', and `--read-timeout',
213 ** Download speed shown by the progress bar is based on the data
214 recently read, rather than the average speed of the entire download.
215 The ETA projection is still based on the overall average.
217 ** It is now possible to connect to FTP servers through FWTK
218 firewalls. Set ftp_proxy to an FTP URL, and Wget will automatically
219 log on to the proxy as "username@host".
221 ** The new option `--retry-connrefused' makes Wget retry downloads
222 even in the face of refused connections, which are otherwise
223 considered a fatal error.
225 ** The new option `--no-dns-cache' may be used to prevent Wget from
228 ** Wget no longer escapes characters in local file names based on
229 whether they're appropriate in URLs. Escaping can still occur for
230 nonprintable characters or for '/', but no longer for frequent
231 characters such as space. You can use the new option
232 --restrict-file-names to relax or strengthen these rules, which can be
233 useful if you dislike the default or if you're downloading to
234 non-native partitions.
236 ** Handling of HTML comments has been dumbed down to conform to what
237 users expect and other browsers do: instead of being treated as SGML
238 declaration, a comment is terminated at the first occurrence of "-->".
239 Use `--strict-comments' to revert to the old behavior.
241 ** Wget now correctly handles relative URIs that begin with "//", such
242 as "//img.foo.com/foo.jpg".
244 ** Boolean options in `.wgetrc' and on the command line now accept
245 values "yes" and "no" along with the traditional "on" and "off".
247 ** It is now possible to specify decimal values for timeouts, waiting
248 periods, and download rate. For instance, `--wait=0.5' now works as
249 expected, as does `--dns-timeout=0.5' and even `--limit-rate=2.5k'.
251 * Wget 1.8.2 is a bugfix release with no user-visible changes.
253 * Wget 1.8.1 is a bugfix release with no user-visible changes.
255 * Changes in Wget 1.8.
257 ** A new progress indicator is now available and used by default.
258 You can choose the progress bar type with `--progress=TYPE'. Two
259 types are available, "bar" (the new default), and "dot" (the old
260 dotted indicator). You can permanently revert to the old progress
261 indicator by putting `progress = dot' in your `.wgetrc'.
263 ** You can limit the download rate of the retrieval using the
264 `--limit-rate' option. For example, `wget --limit-rate=15k URL' will
265 tell Wget not to download the body of the URL faster than 15 kilobytes
268 ** Recursive retrieval and link conversion have been revamped:
270 *** Wget now traverses links breadth-first. This makes the
271 calculation of depth much more reliable than before. Also, recursive
272 downloads are faster and consume *significantly* less memory than
275 *** Links are converted only when the entire retrieval is complete.
276 This is the only safe thing to do, as only then is it known what URLs
277 have been downloaded.
279 *** BASE tags are handled correctly when converting links. Since Wget
280 already resolves <base href="..."> when resolving handling URLs, link
281 conversion now makes the BASE tags point to an empty string.
283 *** HTML anchors are now handled correctly. Links to an anchor in the
284 same document (<a href="#anchorname">), which used to confuse Wget,
285 are now converted correctly.
287 *** When in page-requisites (-p) mode, no-parent (-np) is ignored when
288 retrieving for inline images, stylesheets, and other documents needed
291 *** Page-requisites (-p) mode now works with frames. In other words,
292 `wget -p URL-THAT-USES-FRAMES' will now download the frame HTML files,
293 and all the files that they need to be displayed properly.
295 ** `--base' now works conjunction with `--input-file', providing a
296 base for each URL and thereby allowing the URLs in the file to be
299 ** If a host has more than one IP address, Wget uses the other
300 addresses when accessing the first one fails.
302 ** Host directories now contain port information if the URL is at a
305 ** Wget now supports the robots.txt directives specified in
306 <http://www.robotstxt.org/wc/norobots-rfc.txt>.
308 ** URL parser has been fixed, especially the infamous overzealous
309 quoting. Wget no longer dequotes reserved characters, e.g. `%3F' is
310 no longer translated to `?', nor `%2B' to `+'. Unsafe characters
311 which are not reserved are still escaped, of course.
313 ** No more than 20 successive redirections are allowed.
315 * Wget 1.7.1 is a bugfix release with no user-visible changes.
317 * Changes in Wget 1.7.
319 ** SSL (`https') pages now work if you compile Wget with SSL support;
320 use the `--with-ssl' configure flag. You need to have OpenSSL
323 ** Cookies are now supported. Wget will accept cookies sent by the
324 server and return them in later requests. Additionally, it can load
325 and save cookies to disk, in the same format that Netscape uses.
327 ** "Keep-alive" (persistent) HTTP connections are now supported.
328 Using keep-alive allows Wget to share one TCP/IP connection for
329 many retrievals, making multiple-file downloads faster and less
330 stressing for the server and the network.
332 ** Wget now recognizes FTP directory listings generated by NT and VMS
335 ** It is now possible to recurse through FTP sites where logging in
336 puts you in some directory other than '/'.
338 ** You may now use `~' to mean home directory in `.wgetrc'. For
339 example, `load_cookies = ~/.netscape/cookies.txt' works as you would
342 ** The HTML parser has been rewritten. The new one works more
343 reliably, allows finer-grained control over which tags and attributes
344 are detected, and has better support for some features like correctly
345 skipping comments and declarations, decoding entities, etc. It is
348 ** <meta name="robots"> tags are now respected.
350 ** Wget's internal tables now use hash tables instead of linked lists
351 where appropriate. This results in huge speedups when retrieving
352 large sites (thousands of documents).
354 ** Wget now has a man page, automatically generated from the Texinfo
355 documentation. (The last version that shipped with a man page was
356 1.4.5). To get this, you need to have pod2man from the Perl
357 distribution installed on your system.
359 * Changes in Wget 1.6
361 ** Administrative changes.
363 *** Maintainership. Due to Hrvoje being plagued with a "real job",
364 Dan Harkless is the most active maintainer (not that he doesn't have a
365 real job as well). Hrvoje still participates occasionally, and both
366 are being helped by many other people.
368 *** Web page. Thanks to Jan Prikryl, Wget has an "official" web page.
371 http://sunsite.dk/wget/
373 *** Anonymous CVS. Thanks to ever-helpful Karsten Thygesen, Wget
374 sources are now available at an anonymous CVS server. Take a look at
375 the web page for downloading instructions.
377 ** New -K / --backup-converted / backup_converted = on option causes files
378 modified due to -k to be saved with a .orig prefix before being changed. When
379 using -N as well, it is these .orig files that are compared against the server.
381 ** New --follow-tags / follow_tags = ... option allows you to restrict
382 Wget to following only certain HTML tags when doing a recursive
383 retrieval. -G / --ignore-tags / ignore_tags = ... is just the
384 opposite -- all tags but the ones you specify will be followed.
386 ** New --waitretry / waitretry = SECONDS option allows waiting between retries
387 of failed downloads. Wget will use "linear" backoff, waiting 1 second after the
388 first failure, 2 after the second, up to SECONDS. waitretry is set to 10 by
389 default in the system wgetrc.
391 ** New -p / --page-requisites / page_requisites = on option causes
392 Wget to download all ancillary files necessary to display a given HTML
393 page properly (e.g. inlined images).
395 ** New -E / --html-extension / html_extension = on option causes Wget
396 to append ".html" to text/html filenames not ending in regexp
397 "\.[Hh][Tt][Mm][Ll]?".
399 ** New type of .wgetrc command -- "lockable Boolean". Can be set to on, off,
400 always, or never. This allows the .wgetrc to override the commandline. So far,
401 passive_ftp is the only .wgetrc command which takes a lockable Boolean.
403 ** A number of new translation files have been added.
405 ** New --bind-address / bind_address = <address> option for people on hosts
406 bound to multiple IP addresses.
408 ** wget now accepts (illegal per HTTP spec) relative URLs in HTTP redirects.
410 * Wget 1.5.3 is a bugfix release with no user-visible changes.
412 * Wget 1.5.2 is a bugfix release with no user-visible changes.
414 * Wget 1.5.1 is a bugfix release with no user-visible changes.
416 * Changes in Wget 1.5.0
418 ** Wget speaks many languages!
420 On systems with gettext(), Wget will output messages in the language
421 set by the current locale, if available. At this time we support
422 Czech, German, Croatian, Italian, Norwegian and Portuguese.
424 ** Opie (Skey) is now supported with FTP.
426 ** HTTP Digest Access Authentication (RFC2069) is now supported.
428 ** The new `-b' option makes Wget go to background automatically.
430 ** The `-I' and `-X' options now accept wildcard arguments.
432 ** The `-w' option now accepts suffixes `s' for seconds, `m' for
433 minutes, `h' for hours, `d' for days and `w' for weeks.
435 ** Upon getting SIGHUP, the whole previous log is now copied to
438 ** Wget now understands proxy settings with explicit usernames and
439 passwords, e.g. `http://user:password@proxy.foo.com/'.
441 ** You can use the new `--cut-dirs' option to make Wget create less
444 ** The `;type=a' appendix to FTP URLs is now recognized. For
445 instance, the following command will retrieve the welcoming message in
448 wget "ftp://ftp.somewhere.com/welcome.msg;type=a"
450 ** `--help' and `--version' options have been redone to to conform to
451 standards set by other GNU utilities.
453 ** Wget should now be compilable under MS Windows environment. MS
454 Visual C++ and Watcom C have been used successfully.
456 ** If the file length is known, percentages are displayed during
459 ** The manual page, now hopelessly out of date, is no longer
460 distributed with Wget.
462 * Wget 1.4.5 is a bugfix release with no user-visible changes.
464 * Wget 1.4.4 is a bugfix release with no user-visible changes.
466 * Changes in Wget 1.4.3
468 ** Wget is now a GNU utility.
470 ** Can do passive FTP.
474 ** Info documentation expanded.
476 ** Compiles on pre-ANSI compilers.
478 ** Global wgetrc now goes to /usr/local/etc (i.e. $sysconfdir).
482 * Changes in Wget 1.4.2
484 ** New mirror site at ftp://sunsite.auc.dk/pub/infosystems/wget/,
485 thanks to Karsten Thygesen.
487 ** Mailing list! Mail to wget-request@sunsite.auc.dk to subscribe.
489 ** New option --delete-after for proxy prefetching.
491 ** New option --retr-symlinks to retrieve symbolic links like plain
494 ** rmold.pl -- script to remove files deleted on the remote server
496 ** --convert-links should work now.
500 * Changes in Wget 1.4.1
504 ** Added -I (the opposite of -X).
506 ** Dot tracing is now customizable; try wget --dot-style=binary
508 * Changes in Wget 1.4.0
510 ** Wget 1.4.0 [formerly known as Geturl] is an extensive rewrite of
511 Geturl. Although many things look suspiciously similar, most of the
512 stuff was rewritten, like recursive retrieval, HTTP, FTP and mostly
513 everything else. Wget should be now easier to debug, maintain and,
514 most importantly, use.
516 ** Recursive HTTP should now work without glitches, even with Location
517 changes, server-generated directory listings and other naughty stuff.
519 ** HTTP regetting is supported on servers that support Range
520 specification. WWW authorization is supported -- try
521 wget http://user:password@hostname/
523 ** FTP support was rewritten and widely enhanced. Globbing should now
524 work flawlessly. Symbolic links are created locally. All the
525 information the Unix-style ls listing can give is now recognized.
527 ** Recursive FTP is supported, e.g.
528 wget -r ftp://gnjilux.cc.fer.hr/pub/unix/util/
530 ** You can specify "rejected" directories, to which you do not want to
531 enter, e.g. with wget -X /pub
533 ** Time-stamping is supported, with both HTTP and FTP. Try wget -N URL.
535 ** A new texinfo reference manual is provided. It can be read with
536 Emacs, standalone info, or converted to HTML, dvi or postscript.
538 ** Fixed a long-standing bug, so that Wget now works over SLIP
541 ** You can have a system-wide wgetrc (/usr/local/lib/wgetrc by
542 default). Settings in $HOME/.wgetrc override the global ones, of
545 ** You can set up quota in .wgetrc to prevent sucking too much
546 data. Try `quota = 5M' in .wgetrc (or quota = 100K if you want your
547 sysadmin to like you).
549 ** Download rate is printed after retrieval.
551 ** Wget now sends the `Referer' header when retrieving
554 ** With the new --no-parent option Wget can retrieve FTP recursively
555 through a proxy server.
557 ** HTML parser, as well as the whole of Wget was rewritten to be much
558 faster and less memory-consuming (yes, both).
560 ** Absolute links can be converted to relative links locally. Check
563 ** Wget catches hangup, filtering the output to a log file and
564 resuming work. Try kill -HUP %?wget.
566 ** User-defined headers can be sent. Try
568 wget http://fly.cc.her.hr/ --header='Accept-Charset: iso-8859-2'
570 ** Acceptance/Rejection lists may contain wildcards.
572 ** Wget can display HTTP headers and/or FTP server response with the
573 new `-S' option. It can save the original HTTP headers with `-s'.
575 ** socks library is now supported (thanks to Antonio Rosella
576 <Antonio.Rosella@agip.it>). Configure with --with-socks.
578 ** There is a nicer display of REST-ed output.
580 ** Many new options (like -x to force directory hierarchy, or -m to
581 turn on mirroring options).
583 ** Wget is now distributed under GNU General Public License (GPL).
585 ** Lots of small features I can't remember. :-)
587 ** A host of bugfixes.
589 * Changes in Geturl 1.3
591 ** Added FTP globbing support (ftp://fly.cc.fer.hr/*)
593 ** Added support for no_proxy
595 ** Added support for ftp://user:password@host/
597 ** Added support for %xx in URL syntax
599 ** More natural command-line options
601 ** Added -e switch to execute .geturlrc commands from the command-line
603 ** Added support for robots.txt
605 ** Fixed some minor bugs
607 * Geturl 1.2 is a bugfix release with no user-visible changes.
609 * Changes in Geturl 1.1
611 ** REST supported in FTP
613 ** Proxy servers supported
615 ** GNU getopt used, which enables command-line arguments to be ordered
616 as you wish, e.g. geturl http://fly.cc.fer.hr/ -vo log is the same as
617 geturl -vo log http://fly.cc.fer.hr/
619 ** Netscape-compatible URL syntax for HTTP supported: host[:port]/dir/file
621 ** NcFTP-compatible colon URL syntax for FTP supported: host:/dir/file
623 ** <base href="xxx"> supported
625 ** autoconf supported
