9 * Changes in Wget 1.12 (MAINLINE)
11 ** --default-page option added to support alternative default names for
14 ** Added support for CSS. This includes:
15 - Parsing links from CSS files, and from CSS content found in HTML
16 style tags and attributes.
17 - Supporting conversion of links found within CSS content, when
18 --convert-links is specified.
19 - Ensuring that CSS files end in the ".css" filename extension,
20 when --convert-links is specified.
22 CSS support in Wget is thanks to Ted Mielczarek
23 <ted.mielczarek@gmail.com>.
25 ** --ask-password option (and associated wgetrc command) added to
26 support password prompts at the console.
28 ** The --input-file option now also handles retrieving links from
31 ** Several previously existing, but undocumented .wgetrc options
32 are now documented: save_headers, spider, and user_agent.
34 * Changes in Wget 1.11.4
36 ** Fixed an issue (apparently a regression) where -O would refuse to
37 download when -nc was given, even though the file didn't exist.
39 ** Fixed a situation where Wget could abort with --continue if the
40 remote server gives a content-length of zero when the file exists
43 ** Fixed a crash on some systems, due to Wget casting a pointer-to-long
44 to a pointer-to-time_t.
46 ** Translation updates for Catalan.
48 * Changes in Wget 1.11.3
50 ** Downgraded -N with -O to a warning, rather than an error.
52 ** Translation updates
54 * Changes in Wget 1.11.2
56 ** Fixed a problem in authenticating over HTTPS through a proxy.
57 (Regression in 1.11 over 1.10.2.)
59 ** The combination of -r or -p with -O, which was disallowed in 1.11,
60 has been downgraded to a warning in 1.11.2. (-O and -N, which was never
61 meaningful, is still an error.)
63 ** Further improvements to progress bar displays in non-English locales
64 (too many spaces could be inserted, causing the display to scroll).
66 ** Successive invocations of Wget on FTP URLS, with --no-remove-listing
67 and --continue, was causing Wget to append, rather than replace,
68 information in the .listing file, and thereby download the same files
69 multiple times. This has been fixed in 1.11.2.
71 ** Wget 1.11 no longer allowed ".." to persist at the beginning of URLs,
72 for improved conformance with RFC 3986. However, this behavior presents
73 problems for some FTP setups, and so they are now preserved again, for
76 * Changes in Wget 1.11.1.
78 ** Interrupted downloads no longer result in renaming the file
79 (regression in 1.11 over 1.10.2).
81 ** Progress bar now displays correctly in non-English locales (and a
82 related assertion failure was fixed).
84 ** Wget no longer issues a GET request over HTTP for files it should
85 know it's not going to download (regression in 1.11 over 1.10.2).
87 ** Added option --auth-no-challenge, to support broken pre-1.11
88 authentication-before-server-challenge, which turns out to still be
89 useful for some limited cases.
91 ** Documentation of accept/reject lists in the manual's "Types of
92 Files" section now explains various aspects of their behavior that may
93 be surprising, and notes that they may change in the future.
95 ** Documentation of --no-parents now explains how a trailing slash, or
96 lack thereof, in the specified URL, will affect behavior.
98 * Changes in Wget 1.11.
100 ** Timestamping now uses the value from the most recent HTTP response,
101 rather than the first one it got.
103 ** Authentication information is no longer sent as part of the Referer
104 header in recursive fetches.
106 ** No authentication credentials are sent until a challenge is issued,
107 for improved security. Authentication handling is still not
108 RFC-compliant, as once a Basic challenge has been received, it will
109 assume it can send credentials to any URL at that same host, and not
110 just the ones at or below the original authenticated location.
111 Credentials for Digest authentication are still never saved or issued
112 automatically, and continue to require a challenge for each resource.
114 ** Added --max-redirect option, allowing the user to specify what should
115 be the maximum number of HTTP redirects to follow.
117 ** Wget now supports saving HTTP downloads using file names specified by
118 the `Content-Disposition' header. This is a standard way of specifying
119 the file name used by many web dynamically generated pages. However, the
120 current implementation is inefficient, and known to have bugs. It is
121 EXPERIMENTAL only, and not enabled by default. Use --content-disposition
124 ** The new option `--ignore-case' makes Wget ignore case when
125 matching files, directories, and wildcards. This affects the -X, -I,
126 -A, and -R options, as well as globbing in FTP URLs.
128 ** ETA projection is now displayed in "dot" progress output as well as
129 in the default progress bar. (The dot progress is used by default when
130 logging Wget's output to file using the `-o' option.)
132 ** The "lockable boolean" argument type is no longer supported. It
133 was only used by the passive_ftp .wgetrc setting. If you're running
134 broken scripts or Perl modules that unconditionally specify
135 `--passive-ftp' and your firewall disallows it, you can override them
136 by replacing wget with a script that execs wget "$@" --no-passive-ftp.
138 ** The source code has been migrated to Mercurial. The repositories are
139 available at http://hg.addictivecode.org/. Prior to this, the source
140 code was hosted on Subversion (migrated from the original CVS); you can
141 still get access to older tags and branches for Wget in the Subversion
142 repository at http://addictivecode.org/svn/wget/.
144 * Changes in Wget 1.10.
146 ** Downloading files larger than 2GB, sometimes referred to as "large
147 files", now works on systems that support them. This includes the
148 majority of modern Unixes, as well as MS Windows.
150 ** IPv6 is now supported by Wget. Unlike the experimental code in
151 1.9, this version supports dual-family systems. The new flags
152 `--inet4' and `--inet6' (or `-4' and `-6' for short) force the use of
153 IPv4 and IPv6 respectively. Note that IPv6 support has not yet been
156 ** Microsoft's proprietary "NTLM" method of HTTP authentication is now
157 supported. This authentication method is undocumented and only used
158 by IIS. Note that *proxy* authentication is not supported in this
159 release; you can only authenticate to the target web site.
161 ** Wget no longer truncates partially downloaded files when download
162 has to start over because the server doesn't support Range. Instead,
163 with such servers Wget now simply ignores the data up to the byte
164 where the last attempt left off, and only then continues appending to
165 the file. That way the downloaded file never shrinks, and download
166 retries from servers without support for partial downloads work even
167 when downloading to stdout.
171 *** SSL/TLS downloads now attempt to verify the server's certificate
172 against the recognized certificate authorities. This requires CA
173 certificates to have been installed in a location visible to the
174 OpenSSL library. If this is not the case, you can get the bundle
175 yourself from a source you trust (for example, the bundle extracted
176 from Mozilla available at http://curl.haxx.se/docs/caextract.html),
177 and point Wget to the PEM file using the `--ca-certificate'
178 command-line option or the corresponding `.wgetrc' command.
180 *** Secure downloads now verify that the host name in the URL matches
181 the "common name" in the certificate presented by the server.
183 *** Although the above checks provide more secure downloads, they
184 unavoidably break interoperability with some sites that worked with
185 previous versions, particularly those using self-signed, expired, or
186 otherwise invalid certificates. If you encounter "certificate
187 verification" errors or complaints that "common name doesn't match
188 requested host name" and are convinced of the site's authenticity, you
189 can use `--no-check-certificate' to bypass both checks.
191 *** Talking to SSL/TLS servers over proxies now actually works.
192 Previous versions of Wget erroneously sent GET requests for https
193 URLs. Wget 1.10 utilizes the CONNECT method designed for this
196 *** The SSL/TLS-related options have been redesigned and, for the
197 first time, documented in the manual. The old, undocumented, options
198 are no longer supported.
200 ** Passive FTP is now the default FTP transfer mode. Use
201 `--no-passive-ftp' or specify `passive_ftp = off' in your init file to
202 revert to the old behavior.
204 ** The `--header' option can now be used to override generated
205 headers. For example, `wget --header="Host: foo.bar"
206 http://127.0.0.1' tells Wget to connect to localhost, but to specify
207 "foo.bar" in the `Host' header. In previous versions such use of
208 `--header' lead to duplicate headers in HTTP requests.
210 ** The responses without headers, aka "HTTP 0.9" responses, are
211 detected and handled. Although HTTP 0.9 has long been obsolete, it is
212 still occasionally used, sometimes by accident.
214 ** The progress bar is now updated regularly even when the data does
215 not arrive from the network.
217 ** Wget no longer preserves permissions of files retrieved by FTP by
218 default. Anonymous FTP servers frequently use permissions like "664",
219 which might not be what the user wants. The new option
220 `--preserve-permissions' and the corresponding `.wgetrc' variable can
221 be used to revert to the old behavior.
223 ** The new option `--protocol-directories' instructs Wget to also use
224 the protocol name as a directory component of local file names.
226 ** Options that previously unconditionally set or unset various flags
227 are now boolean options that can be invoked as either `--OPTION' or
228 `--no-OPTION'. Options that required an argument "on" or "off" have
229 also been changed this way, but they still accept the old syntax for
230 backward compatibility. For example, instead of `--glob=off' you can
233 Allowing `--no-OPTION' for every `--OPTION' and the other way around
234 is useful because it allows the user to override non-default behavior
235 specified via `.wgetrc'.
237 ** The new option `--keep-session-cookies' causes `--save-cookies' to
238 save session cookies (normally only kept in memory) along with the
239 permanent ones. This is useful because many sites track important
240 information, such as whether the user has authenticated, in session
241 cookies. With this option multiple Wget runs are treated as a single
244 ** Wget now supports the --ftp-user and --ftp-password command
245 switches to set username and password for FTP, and the --user and
246 --password command switches to set username and password for both FTP
247 and HTTP. The --http-passwd and --proxy-passwd command switches have
248 been renamed to --http-password and --proxy-password respectively, and
249 the related http_passwd and proxy_passwd .wgetrc commands to
250 http_password and proxy_password respectively. The login and passwd
251 .wgetrc commands have been deprecated.
253 * `wget -b' now works correctly under Windows.
255 * Wget 1.9.1 is a bugfix release with no user-visible changes.
257 * Changes in Wget 1.9.
259 ** It is now possible to specify that POST method be used for HTTP
260 requests. For example, `wget --post-data="id=foo&data=bar" URL' will
261 send a POST request with the specified contents.
263 ** IPv6 support is available, although it's still experimental.
265 ** The `--timeout' option now also affects DNS lookup and establishing
266 the TCP connection. Previously it only affected reading and writing
267 data. Those three timeouts can be set separately using
268 `--dns-timeout', `--connection-timeout', and `--read-timeout',
271 ** Download speed shown by the progress bar is based on the data
272 recently read, rather than the average speed of the entire download.
273 The ETA projection is still based on the overall average.
275 ** It is now possible to connect to FTP servers through FWTK
276 firewalls. Set ftp_proxy to an FTP URL, and Wget will automatically
277 log on to the proxy as "username@host".
279 ** The new option `--retry-connrefused' makes Wget retry downloads
280 even in the face of refused connections, which are otherwise
281 considered a fatal error.
283 ** The new option `--no-dns-cache' may be used to prevent Wget from
286 ** Wget no longer escapes characters in local file names based on
287 whether they're appropriate in URLs. Escaping can still occur for
288 nonprintable characters or for '/', but no longer for frequent
289 characters such as space. You can use the new option
290 --restrict-file-names to relax or strengthen these rules, which can be
291 useful if you dislike the default or if you're downloading to
292 non-native partitions.
294 ** Handling of HTML comments has been dumbed down to conform to what
295 users expect and other browsers do: instead of being treated as SGML
296 declaration, a comment is terminated at the first occurrence of "-->".
297 Use `--strict-comments' to revert to the old behavior.
299 ** Wget now correctly handles relative URIs that begin with "//", such
300 as "//img.foo.com/foo.jpg".
302 ** Boolean options in `.wgetrc' and on the command line now accept
303 values "yes" and "no" along with the traditional "on" and "off".
305 ** It is now possible to specify decimal values for timeouts, waiting
306 periods, and download rate. For instance, `--wait=0.5' now works as
307 expected, as does `--dns-timeout=0.5' and even `--limit-rate=2.5k'.
309 * Wget 1.8.2 is a bugfix release with no user-visible changes.
311 * Wget 1.8.1 is a bugfix release with no user-visible changes.
313 * Changes in Wget 1.8.
315 ** A new progress indicator is now available and used by default.
316 You can choose the progress bar type with `--progress=TYPE'. Two
317 types are available, "bar" (the new default), and "dot" (the old
318 dotted indicator). You can permanently revert to the old progress
319 indicator by putting `progress = dot' in your `.wgetrc'.
321 ** You can limit the download rate of the retrieval using the
322 `--limit-rate' option. For example, `wget --limit-rate=15k URL' will
323 tell Wget not to download the body of the URL faster than 15 kilobytes
326 ** Recursive retrieval and link conversion have been revamped:
328 *** Wget now traverses links breadth-first. This makes the
329 calculation of depth much more reliable than before. Also, recursive
330 downloads are faster and consume *significantly* less memory than
333 *** Links are converted only when the entire retrieval is complete.
334 This is the only safe thing to do, as only then is it known what URLs
335 have been downloaded.
337 *** BASE tags are handled correctly when converting links. Since Wget
338 already resolves <base href="..."> when resolving handling URLs, link
339 conversion now makes the BASE tags point to an empty string.
341 *** HTML anchors are now handled correctly. Links to an anchor in the
342 same document (<a href="#anchorname">), which used to confuse Wget,
343 are now converted correctly.
345 *** When in page-requisites (-p) mode, no-parent (-np) is ignored when
346 retrieving for inline images, stylesheets, and other documents needed
349 *** Page-requisites (-p) mode now works with frames. In other words,
350 `wget -p URL-THAT-USES-FRAMES' will now download the frame HTML files,
351 and all the files that they need to be displayed properly.
353 ** `--base' now works conjunction with `--input-file', providing a
354 base for each URL and thereby allowing the URLs in the file to be
357 ** If a host has more than one IP address, Wget uses the other
358 addresses when accessing the first one fails.
360 ** Host directories now contain port information if the URL is at a
363 ** Wget now supports the robots.txt directives specified in
364 <http://www.robotstxt.org/wc/norobots-rfc.txt>.
366 ** URL parser has been fixed, especially the infamous overzealous
367 quoting. Wget no longer dequotes reserved characters, e.g. `%3F' is
368 no longer translated to `?', nor `%2B' to `+'. Unsafe characters
369 which are not reserved are still escaped, of course.
371 ** No more than 20 successive redirections are allowed.
373 * Wget 1.7.1 is a bugfix release with no user-visible changes.
375 * Changes in Wget 1.7.
377 ** SSL (`https') pages now work if you compile Wget with SSL support;
378 use the `--with-ssl' configure flag. You need to have OpenSSL
381 ** Cookies are now supported. Wget will accept cookies sent by the
382 server and return them in later requests. Additionally, it can load
383 and save cookies to disk, in the same format that Netscape uses.
385 ** "Keep-alive" (persistent) HTTP connections are now supported.
386 Using keep-alive allows Wget to share one TCP/IP connection for
387 many retrievals, making multiple-file downloads faster and less
388 stressing for the server and the network.
390 ** Wget now recognizes FTP directory listings generated by NT and VMS
393 ** It is now possible to recurse through FTP sites where logging in
394 puts you in some directory other than '/'.
396 ** You may now use `~' to mean home directory in `.wgetrc'. For
397 example, `load_cookies = ~/.netscape/cookies.txt' works as you would
400 ** The HTML parser has been rewritten. The new one works more
401 reliably, allows finer-grained control over which tags and attributes
402 are detected, and has better support for some features like correctly
403 skipping comments and declarations, decoding entities, etc. It is
406 ** <meta name="robots"> tags are now respected.
408 ** Wget's internal tables now use hash tables instead of linked lists
409 where appropriate. This results in huge speedups when retrieving
410 large sites (thousands of documents).
412 ** Wget now has a man page, automatically generated from the Texinfo
413 documentation. (The last version that shipped with a man page was
414 1.4.5). To get this, you need to have pod2man from the Perl
415 distribution installed on your system.
417 * Changes in Wget 1.6
419 ** Administrative changes.
421 *** Maintainership. Due to Hrvoje being plagued with a "real job",
422 Dan Harkless is the most active maintainer (not that he doesn't have a
423 real job as well). Hrvoje still participates occasionally, and both
424 are being helped by many other people.
426 *** Web page. Thanks to Jan Prikryl, Wget has an "official" web page.
429 http://sunsite.dk/wget/
431 *** Anonymous CVS. Thanks to ever-helpful Karsten Thygesen, Wget
432 sources are now available at an anonymous CVS server. Take a look at
433 the web page for downloading instructions.
435 ** New -K / --backup-converted / backup_converted = on option causes files
436 modified due to -k to be saved with a .orig prefix before being changed. When
437 using -N as well, it is these .orig files that are compared against the server.
439 ** New --follow-tags / follow_tags = ... option allows you to restrict
440 Wget to following only certain HTML tags when doing a recursive
441 retrieval. -G / --ignore-tags / ignore_tags = ... is just the
442 opposite -- all tags but the ones you specify will be followed.
444 ** New --waitretry / waitretry = SECONDS option allows waiting between retries
445 of failed downloads. Wget will use "linear" backoff, waiting 1 second after the
446 first failure, 2 after the second, up to SECONDS. waitretry is set to 10 by
447 default in the system wgetrc.
449 ** New -p / --page-requisites / page_requisites = on option causes
450 Wget to download all ancillary files necessary to display a given HTML
451 page properly (e.g. inlined images).
453 ** New -E / --html-extension / html_extension = on option causes Wget
454 to append ".html" to text/html filenames not ending in regexp
455 "\.[Hh][Tt][Mm][Ll]?".
457 ** New type of .wgetrc command -- "lockable Boolean". Can be set to on, off,
458 always, or never. This allows the .wgetrc to override the commandline. So far,
459 passive_ftp is the only .wgetrc command which takes a lockable Boolean.
461 ** A number of new translation files have been added.
463 ** New --bind-address / bind_address = <address> option for people on hosts
464 bound to multiple IP addresses.
466 ** wget now accepts (illegal per HTTP spec) relative URLs in HTTP redirects.
468 * Wget 1.5.3 is a bugfix release with no user-visible changes.
470 * Wget 1.5.2 is a bugfix release with no user-visible changes.
472 * Wget 1.5.1 is a bugfix release with no user-visible changes.
474 * Changes in Wget 1.5.0
476 ** Wget speaks many languages!
478 On systems with gettext(), Wget will output messages in the language
479 set by the current locale, if available. At this time we support
480 Czech, German, Croatian, Italian, Norwegian and Portuguese.
482 ** Opie (Skey) is now supported with FTP.
484 ** HTTP Digest Access Authentication (RFC2069) is now supported.
486 ** The new `-b' option makes Wget go to background automatically.
488 ** The `-I' and `-X' options now accept wildcard arguments.
490 ** The `-w' option now accepts suffixes `s' for seconds, `m' for
491 minutes, `h' for hours, `d' for days and `w' for weeks.
493 ** Upon getting SIGHUP, the whole previous log is now copied to
496 ** Wget now understands proxy settings with explicit usernames and
497 passwords, e.g. `http://user:password@proxy.foo.com/'.
499 ** You can use the new `--cut-dirs' option to make Wget create less
502 ** The `;type=a' appendix to FTP URLs is now recognized. For
503 instance, the following command will retrieve the welcoming message in
506 wget "ftp://ftp.somewhere.com/welcome.msg;type=a"
508 ** `--help' and `--version' options have been redone to to conform to
509 standards set by other GNU utilities.
511 ** Wget should now be compilable under MS Windows environment. MS
512 Visual C++ and Watcom C have been used successfully.
514 ** If the file length is known, percentages are displayed during
517 ** The manual page, now hopelessly out of date, is no longer
518 distributed with Wget.
520 * Wget 1.4.5 is a bugfix release with no user-visible changes.
522 * Wget 1.4.4 is a bugfix release with no user-visible changes.
524 * Changes in Wget 1.4.3
526 ** Wget is now a GNU utility.
528 ** Can do passive FTP.
532 ** Info documentation expanded.
534 ** Compiles on pre-ANSI compilers.
536 ** Global wgetrc now goes to /usr/local/etc (i.e. $sysconfdir).
540 * Changes in Wget 1.4.2
542 ** New mirror site at ftp://sunsite.auc.dk/pub/infosystems/wget/,
543 thanks to Karsten Thygesen.
545 ** Mailing list! Mail to wget-request@sunsite.auc.dk to subscribe.
547 ** New option --delete-after for proxy prefetching.
549 ** New option --retr-symlinks to retrieve symbolic links like plain
552 ** rmold.pl -- script to remove files deleted on the remote server
554 ** --convert-links should work now.
558 * Changes in Wget 1.4.1
562 ** Added -I (the opposite of -X).
564 ** Dot tracing is now customizable; try wget --dot-style=binary
566 * Changes in Wget 1.4.0
568 ** Wget 1.4.0 [formerly known as Geturl] is an extensive rewrite of
569 Geturl. Although many things look suspiciously similar, most of the
570 stuff was rewritten, like recursive retrieval, HTTP, FTP and mostly
571 everything else. Wget should be now easier to debug, maintain and,
572 most importantly, use.
574 ** Recursive HTTP should now work without glitches, even with Location
575 changes, server-generated directory listings and other naughty stuff.
577 ** HTTP regetting is supported on servers that support Range
578 specification. WWW authorization is supported -- try
579 wget http://user:password@hostname/
581 ** FTP support was rewritten and widely enhanced. Globbing should now
582 work flawlessly. Symbolic links are created locally. All the
583 information the Unix-style ls listing can give is now recognized.
585 ** Recursive FTP is supported, e.g.
586 wget -r ftp://gnjilux.cc.fer.hr/pub/unix/util/
588 ** You can specify "rejected" directories, to which you do not want to
589 enter, e.g. with wget -X /pub
591 ** Time-stamping is supported, with both HTTP and FTP. Try wget -N URL.
593 ** A new texinfo reference manual is provided. It can be read with
594 Emacs, standalone info, or converted to HTML, dvi or postscript.
596 ** Fixed a long-standing bug, so that Wget now works over SLIP
599 ** You can have a system-wide wgetrc (/usr/local/lib/wgetrc by
600 default). Settings in $HOME/.wgetrc override the global ones, of
603 ** You can set up quota in .wgetrc to prevent sucking too much
604 data. Try `quota = 5M' in .wgetrc (or quota = 100K if you want your
605 sysadmin to like you).
607 ** Download rate is printed after retrieval.
609 ** Wget now sends the `Referer' header when retrieving
612 ** With the new --no-parent option Wget can retrieve FTP recursively
613 through a proxy server.
615 ** HTML parser, as well as the whole of Wget was rewritten to be much
616 faster and less memory-consuming (yes, both).
618 ** Absolute links can be converted to relative links locally. Check
621 ** Wget catches hangup, filtering the output to a log file and
622 resuming work. Try kill -HUP %?wget.
624 ** User-defined headers can be sent. Try
626 wget http://fly.cc.her.hr/ --header='Accept-Charset: iso-8859-2'
628 ** Acceptance/Rejection lists may contain wildcards.
630 ** Wget can display HTTP headers and/or FTP server response with the
