6 Please send GNU Wget bug reports to <bug-wget@gnu.org>.
8 * Changes in Wget 1.11.
10 ** Wget now saves HTTP downloads using file names specified by the
11 `Content-Disposition' header. This is a standard way of specifying
12 the file name used by many web dynamically generated pages.
14 ** The GnuTLS library is now also supported for https downloads.
15 This is still work-in-progress. OpenSSL is still used by default; use
16 --with-ssl=gnutls to build with GnuTLS. OpenSSL is still required for
17 NTLM authorization to work, but this should eventually change.
19 ** The new option `--ignore-case' makes Wget ignore case when
20 matching files, directories, and wildcards. This affects the -X, -I,
21 -A, and -R options, as well as globbing in FTP URLs.
23 ** ETA projection is now displayed in "dot" progress output as well as
24 in the default progress bar. (The dot progress is used by default when
25 logging Wget's output to file using the `-o' option.)
27 ** The "lockable boolean" argument type is no longer supported. It
28 was only used by the passive_ftp .wgetrc setting. If you're running
29 broken scripts or Perl modules that unconditionally specify
30 `--passive-ftp' and your firewall disallows it, you can override them
31 by replacing wget with a script that execs wget "$@" --no-passive-ftp.
33 ** The source code has migrated from CVS to Subversion. The
34 repository is available at http://svn.dotsrc.org/repo/wget/; to
35 checkout the trunk to a directory named `wget', use something like
36 `svn checkout http://svn.dotsrc.org/repo/wget/trunk/ wget'.
38 * Changes in Wget 1.10.
40 ** Downloading files larger than 2GB, sometimes referred to as "large
41 files", now works on systems that support them. This includes the
42 majority of modern Unixes, as well as MS Windows.
44 ** IPv6 is now supported by Wget. Unlike the experimental code in
45 1.9, this version supports dual-family systems. The new flags
46 `--inet4' and `--inet6' (or `-4' and `-6' for short) force the use of
47 IPv4 and IPv6 respectively. Note that IPv6 support has not yet been
50 ** Microsoft's proprietary "NTLM" method of HTTP authentication is now
51 supported. This authentication method is undocumented and only used
52 by IIS. Note that *proxy* authentication is not supported in this
53 release; you can only authenticate to the target web site.
55 ** Wget no longer truncates partially downloaded files when download
56 has to start over because the server doesn't support Range. Instead,
57 with such servers Wget now simply ignores the data up to the byte
58 where the last attempt left off, and only then continues appending to
59 the file. That way the downloaded file never shrinks, and download
60 retries from servers without support for partial downloads work even
61 when downloading to stdout.
65 *** SSL/TLS downloads now attempt to verify the server's certificate
66 against the recognized certificate authorities. This requires CA
67 certificates to have been installed in a location visible to the
68 OpenSSL library. If this is not the case, you can get the bundle
69 yourself from a source you trust (for example, the bundle extracted
70 from Mozilla available at http://curl.haxx.se/docs/caextract.html),
71 and point Wget to the PEM file using the `--ca-certificate'
72 command-line option or the corresponding `.wgetrc' command.
74 *** Secure downloads now verify that the host name in the URL matches
75 the "common name" in the certificate presented by the server.
77 *** Although the above checks provide more secure downloads, they
78 unavoidably break interoperability with some sites that worked with
79 previous versions, particularly those using self-signed, expired, or
80 otherwise invalid certificates. If you encounter "certificate
81 verification" errors or complaints that "common name doesn't match
82 requested host name" and are convinced of the site's authenticity, you
83 can use `--no-check-certificate' to bypass both checks.
85 *** Talking to SSL/TLS servers over proxies now actually works.
86 Previous versions of Wget erroneously sent GET requests for https
87 URLs. Wget 1.10 utilizes the CONNECT method designed for this
90 *** The SSL/TLS-related options have been redesigned and, for the
91 first time, documented in the manual. The old, undocumented, options
92 are no longer supported.
94 ** Passive FTP is now the default FTP transfer mode. Use
95 `--no-passive-ftp' or specify `passive_ftp = off' in your init file to
96 revert to the old behavior.
98 ** The `--header' option can now be used to override generated
99 headers. For example, `wget --header="Host: foo.bar"
100 http://127.0.0.1' tells Wget to connect to localhost, but to specify
101 "foo.bar" in the `Host' header. In previous versions such use of
102 `--header' lead to duplicate headers in HTTP requests.
104 ** The responses without headers, aka "HTTP 0.9" responses, are
105 detected and handled. Although HTTP 0.9 has long been obsolete, it is
106 still occasionally used, sometimes by accident.
108 ** The progress bar is now updated regularly even when the data does
109 not arrive from the network.
111 ** Wget no longer preserves permissions of files retrieved by FTP by
112 default. Anonymous FTP servers frequently use permissions like "664",
113 which might not be what the user wants. The new option
114 `--preserve-permissions' and the corresponding `.wgetrc' variable can
115 be used to revert to the old behavior.
117 ** The new option `--protocol-directories' instructs Wget to also use
118 the protocol name as a directory component of local file names.
120 ** Options that previously unconditionally set or unset various flags
121 are now boolean options that can be invoked as either `--OPTION' or
122 `--no-OPTION'. Options that required an argument "on" or "off" have
123 also been changed this way, but they still accept the old syntax for
124 backward compatibility. For example, instead of `--glob=off' you can
127 Allowing `--no-OPTION' for every `--OPTION' and the other way around
128 is useful because it allows the user to override non-default behavior
129 specified via `.wgetrc'.
131 ** The new option `--keep-session-cookies' causes `--save-cookies' to
132 save session cookies (normally only kept in memory) along with the
133 permanent ones. This is useful because many sites track important
134 information, such as whether the user has authenticated, in session
135 cookies. With this option multiple Wget runs are treated as a single
138 ** Wget now supports the --ftp-user and --ftp-password command
139 switches to set username and password for FTP, and the --user and
140 --password command switches to set username and password for both FTP
141 and HTTP. The --http-passwd and --proxy-passwd command switches have
142 been renamed to --http-password and --proxy-password respectively, and
143 the related http_passwd and proxy_passwd .wgetrc commands to
144 http_password and proxy_password respectively. The login and passwd
145 .wgetrc commands have been deprecated.
147 * `wget -b' now works correctly under Windows.
149 * Wget 1.9.1 is a bugfix release with no user-visible changes.
151 * Changes in Wget 1.9.
153 ** It is now possible to specify that POST method be used for HTTP
154 requests. For example, `wget --post-data="id=foo&data=bar" URL' will
155 send a POST request with the specified contents.
157 ** IPv6 support is available, although it's still experimental.
159 ** The `--timeout' option now also affects DNS lookup and establishing
160 the TCP connection. Previously it only affected reading and writing
161 data. Those three timeouts can be set separately using
162 `--dns-timeout', `--connection-timeout', and `--read-timeout',
165 ** Download speed shown by the progress bar is based on the data
166 recently read, rather than the average speed of the entire download.
167 The ETA projection is still based on the overall average.
169 ** It is now possible to connect to FTP servers through FWTK
170 firewalls. Set ftp_proxy to an FTP URL, and Wget will automatically
171 log on to the proxy as "username@host".
173 ** The new option `--retry-connrefused' makes Wget retry downloads
174 even in the face of refused connections, which are otherwise
175 considered a fatal error.
177 ** The new option `--no-dns-cache' may be used to prevent Wget from
180 ** Wget no longer escapes characters in local file names based on
181 whether they're appropriate in URLs. Escaping can still occur for
182 nonprintable characters or for '/', but no longer for frequent
183 characters such as space. You can use the new option
184 --restrict-file-names to relax or strengthen these rules, which can be
185 useful if you dislike the default or if you're downloading to
186 non-native partitions.
188 ** Handling of HTML comments has been dumbed down to conform to what
189 users expect and other browsers do: instead of being treated as SGML
190 declaration, a comment is terminated at the first occurrence of "-->".
191 Use `--strict-comments' to revert to the old behavior.
193 ** Wget now correctly handles relative URIs that begin with "//", such
194 as "//img.foo.com/foo.jpg".
196 ** Boolean options in `.wgetrc' and on the command line now accept
197 values "yes" and "no" along with the traditional "on" and "off".
199 ** It is now possible to specify decimal values for timeouts, waiting
200 periods, and download rate. For instance, `--wait=0.5' now works as
201 expected, as does `--dns-timeout=0.5' and even `--limit-rate=2.5k'.
203 * Wget 1.8.2 is a bugfix release with no user-visible changes.
205 * Wget 1.8.1 is a bugfix release with no user-visible changes.
207 * Changes in Wget 1.8.
209 ** A new progress indicator is now available and used by default.
210 You can choose the progress bar type with `--progress=TYPE'. Two
211 types are available, "bar" (the new default), and "dot" (the old
212 dotted indicator). You can permanently revert to the old progress
213 indicator by putting `progress = dot' in your `.wgetrc'.
215 ** You can limit the download rate of the retrieval using the
216 `--limit-rate' option. For example, `wget --limit-rate=15k URL' will
217 tell Wget not to download the body of the URL faster than 15 kilobytes
220 ** Recursive retrieval and link conversion have been revamped:
222 *** Wget now traverses links breadth-first. This makes the
223 calculation of depth much more reliable than before. Also, recursive
224 downloads are faster and consume *significantly* less memory than
227 *** Links are converted only when the entire retrieval is complete.
228 This is the only safe thing to do, as only then is it known what URLs
229 have been downloaded.
231 *** BASE tags are handled correctly when converting links. Since Wget
232 already resolves <base href="..."> when resolving handling URLs, link
233 conversion now makes the BASE tags point to an empty string.
235 *** HTML anchors are now handled correctly. Links to an anchor in the
236 same document (<a href="#anchorname">), which used to confuse Wget,
237 are now converted correctly.
239 *** When in page-requisites (-p) mode, no-parent (-np) is ignored when
240 retrieving for inline images, stylesheets, and other documents needed
243 *** Page-requisites (-p) mode now works with frames. In other words,
244 `wget -p URL-THAT-USES-FRAMES' will now download the frame HTML files,
245 and all the files that they need to be displayed properly.
247 ** `--base' now works conjunction with `--input-file', providing a
248 base for each URL and thereby allowing the URLs in the file to be
251 ** If a host has more than one IP address, Wget uses the other
252 addresses when accessing the first one fails.
254 ** Host directories now contain port information if the URL is at a
257 ** Wget now supports the robots.txt directives specified in
258 <http://www.robotstxt.org/wc/norobots-rfc.txt>.
260 ** URL parser has been fixed, especially the infamous overzealous
261 quoting. Wget no longer dequotes reserved characters, e.g. `%3F' is
262 no longer translated to `?', nor `%2B' to `+'. Unsafe characters
263 which are not reserved are still escaped, of course.
265 ** No more than 20 successive redirections are allowed.
267 * Wget 1.7.1 is a bugfix release with no user-visible changes.
269 * Changes in Wget 1.7.
271 ** SSL (`https') pages now work if you compile Wget with SSL support;
272 use the `--with-ssl' configure flag. You need to have OpenSSL
275 ** Cookies are now supported. Wget will accept cookies sent by the
276 server and return them in later requests. Additionally, it can load
277 and save cookies to disk, in the same format that Netscape uses.
279 ** "Keep-alive" (persistent) HTTP connections are now supported.
280 Using keep-alive allows Wget to share one TCP/IP connection for
281 many retrievals, making multiple-file downloads faster and less
282 stressing for the server and the network.
284 ** Wget now recognizes FTP directory listings generated by NT and VMS
287 ** It is now possible to recurse through FTP sites where logging in
288 puts you in some directory other than '/'.
290 ** You may now use `~' to mean home directory in `.wgetrc'. For
291 example, `load_cookies = ~/.netscape/cookies.txt' works as you would
294 ** The HTML parser has been rewritten. The new one works more
295 reliably, allows finer-grained control over which tags and attributes
296 are detected, and has better support for some features like correctly
297 skipping comments and declarations, decoding entities, etc. It is
300 ** <meta name="robots"> tags are now respected.
302 ** Wget's internal tables now use hash tables instead of linked lists
303 where appropriate. This results in huge speedups when retrieving
304 large sites (thousands of documents).
306 ** Wget now has a man page, automatically generated from the Texinfo
307 documentation. (The last version that shipped with a man page was
308 1.4.5). To get this, you need to have pod2man from the Perl
309 distribution installed on your system.
311 * Changes in Wget 1.6
313 ** Administrative changes.
315 *** Maintainership. Due to Hrvoje being plagued with a "real job",
316 Dan Harkless is the most active maintainer (not that he doesn't have a
317 real job as well). Hrvoje still participates occasionally, and both
318 are being helped by many other people.
320 *** Web page. Thanks to Jan Prikryl, Wget has an "official" web page.
323 http://sunsite.dk/wget/
325 *** Anonymous CVS. Thanks to ever-helpful Karsten Thygesen, Wget
326 sources are now available at an anonymous CVS server. Take a look at
327 the web page for downloading instructions.
329 ** New -K / --backup-converted / backup_converted = on option causes files
330 modified due to -k to be saved with a .orig prefix before being changed. When
331 using -N as well, it is these .orig files that are compared against the server.
333 ** New --follow-tags / follow_tags = ... option allows you to restrict
334 Wget to following only certain HTML tags when doing a recursive
335 retrieval. -G / --ignore-tags / ignore_tags = ... is just the
336 opposite -- all tags but the ones you specify will be followed.
338 ** New --waitretry / waitretry = SECONDS option allows waiting between retries
339 of failed downloads. Wget will use "linear" backoff, waiting 1 second after the
340 first failure, 2 after the second, up to SECONDS. waitretry is set to 10 by
341 default in the system wgetrc.
343 ** New -p / --page-requisites / page_requisites = on option causes
344 Wget to download all ancillary files necessary to display a given HTML
345 page properly (e.g. inlined images).
347 ** New -E / --html-extension / html_extension = on option causes Wget
348 to append ".html" to text/html filenames not ending in regexp
349 "\.[Hh][Tt][Mm][Ll]?".
351 ** New type of .wgetrc command -- "lockable Boolean". Can be set to on, off,
352 always, or never. This allows the .wgetrc to override the commandline. So far,
353 passive_ftp is the only .wgetrc command which takes a lockable Boolean.
355 ** A number of new translation files have been added.
357 ** New --bind-address / bind_address = <address> option for people on hosts
358 bound to multiple IP addresses.
360 ** wget now accepts (illegal per HTTP spec) relative URLs in HTTP redirects.
362 * Wget 1.5.3 is a bugfix release with no user-visible changes.
364 * Wget 1.5.2 is a bugfix release with no user-visible changes.
366 * Wget 1.5.1 is a bugfix release with no user-visible changes.
368 * Changes in Wget 1.5.0
370 ** Wget speaks many languages!
372 On systems with gettext(), Wget will output messages in the language
373 set by the current locale, if available. At this time we support
374 Czech, German, Croatian, Italian, Norwegian and Portuguese.
376 ** Opie (Skey) is now supported with FTP.
378 ** HTTP Digest Access Authentication (RFC2069) is now supported.
380 ** The new `-b' option makes Wget go to background automatically.
382 ** The `-I' and `-X' options now accept wildcard arguments.
384 ** The `-w' option now accepts suffixes `s' for seconds, `m' for
385 minutes, `h' for hours, `d' for days and `w' for weeks.
387 ** Upon getting SIGHUP, the whole previous log is now copied to
390 ** Wget now understands proxy settings with explicit usernames and
391 passwords, e.g. `http://user:password@proxy.foo.com/'.
393 ** You can use the new `--cut-dirs' option to make Wget create less
396 ** The `;type=a' appendix to FTP URLs is now recognized. For
397 instance, the following command will retrieve the welcoming message in
400 wget "ftp://ftp.somewhere.com/welcome.msg;type=a"
402 ** `--help' and `--version' options have been redone to to conform to
403 standards set by other GNU utilities.
405 ** Wget should now be compilable under MS Windows environment. MS
406 Visual C++ and Watcom C have been used successfully.
408 ** If the file length is known, percentages are displayed during
411 ** The manual page, now hopelessly out of date, is no longer
412 distributed with Wget.
414 * Wget 1.4.5 is a bugfix release with no user-visible changes.
416 * Wget 1.4.4 is a bugfix release with no user-visible changes.
418 * Changes in Wget 1.4.3
420 ** Wget is now a GNU utility.
422 ** Can do passive FTP.
426 ** Info documentation expanded.
428 ** Compiles on pre-ANSI compilers.
430 ** Global wgetrc now goes to /usr/local/etc (i.e. $sysconfdir).
434 * Changes in Wget 1.4.2
436 ** New mirror site at ftp://sunsite.auc.dk/pub/infosystems/wget/,
437 thanks to Karsten Thygesen.
439 ** Mailing list! Mail to wget-request@sunsite.auc.dk to subscribe.
441 ** New option --delete-after for proxy prefetching.
443 ** New option --retr-symlinks to retrieve symbolic links like plain
446 ** rmold.pl -- script to remove files deleted on the remote server
448 ** --convert-links should work now.
452 * Changes in Wget 1.4.1
456 ** Added -I (the opposite of -X).
458 ** Dot tracing is now customizable; try wget --dot-style=binary
460 * Changes in Wget 1.4.0
462 ** Wget 1.4.0 [formerly known as Geturl] is an extensive rewrite of
463 Geturl. Although many things look suspiciously similar, most of the
464 stuff was rewritten, like recursive retrieval, HTTP, FTP and mostly
465 everything else. Wget should be now easier to debug, maintain and,
466 most importantly, use.
468 ** Recursive HTTP should now work without glitches, even with Location
469 changes, server-generated directory listings and other naughty stuff.
471 ** HTTP regetting is supported on servers that support Range
472 specification. WWW authorization is supported -- try
473 wget http://user:password@hostname/
475 ** FTP support was rewritten and widely enhanced. Globbing should now
476 work flawlessly. Symbolic links are created locally. All the
477 information the Unix-style ls listing can give is now recognized.
479 ** Recursive FTP is supported, e.g.
480 wget -r ftp://gnjilux.cc.fer.hr/pub/unix/util/
482 ** You can specify "rejected" directories, to which you do not want to
483 enter, e.g. with wget -X /pub
485 ** Time-stamping is supported, with both HTTP and FTP. Try wget -N URL.
487 ** A new texinfo reference manual is provided. It can be read with
488 Emacs, standalone info, or converted to HTML, dvi or postscript.
490 ** Fixed a long-standing bug, so that Wget now works over SLIP
493 ** You can have a system-wide wgetrc (/usr/local/lib/wgetrc by
494 default). Settings in $HOME/.wgetrc override the global ones, of
497 ** You can set up quota in .wgetrc to prevent sucking too much
498 data. Try `quota = 5M' in .wgetrc (or quota = 100K if you want your
499 sysadmin to like you).
501 ** Download rate is printed after retrieval.
503 ** Wget now sends the `Referer' header when retrieving
506 ** With the new --no-parent option Wget can retrieve FTP recursively
507 through a proxy server.
509 ** HTML parser, as well as the whole of Wget was rewritten to be much
510 faster and less memory-consuming (yes, both).
512 ** Absolute links can be converted to relative links locally. Check
515 ** Wget catches hangup, filtering the output to a log file and
516 resuming work. Try kill -HUP %?wget.
518 ** User-defined headers can be sent. Try
520 wget http://fly.cc.her.hr/ --header='Accept-Charset: iso-8859-2'
522 ** Acceptance/Rejection lists may contain wildcards.
524 ** Wget can display HTTP headers and/or FTP server response with the
525 new `-S' option. It can save the original HTTP headers with `-s'.
527 ** socks library is now supported (thanks to Antonio Rosella
528 <Antonio.Rosella@agip.it>). Configure with --with-socks.
530 ** There is a nicer display of REST-ed output.
532 ** Many new options (like -x to force directory hierarchy, or -m to
533 turn on mirroring options).
535 ** Wget is now distributed under GNU General Public License (GPL).
537 ** Lots of small features I can't remember. :-)
539 ** A host of bugfixes.
541 * Changes in Geturl 1.3
543 ** Added FTP globbing support (ftp://fly.cc.fer.hr/*)
545 ** Added support for no_proxy
547 ** Added support for ftp://user:password@host/
549 ** Added support for %xx in URL syntax
551 ** More natural command-line options
553 ** Added -e switch to execute .geturlrc commands from the command-line
555 ** Added support for robots.txt
557 ** Fixed some minor bugs
559 * Geturl 1.2 is a bugfix release with no user-visible changes.
561 * Changes in Geturl 1.1
563 ** REST supported in FTP
565 ** Proxy servers supported
567 ** GNU getopt used, which enables command-line arguments to be ordered
568 as you wish, e.g. geturl http://fly.cc.fer.hr/ -vo log is the same as
569 geturl -vo log http://fly.cc.fer.hr/
571 ** Netscape-compatible URL syntax for HTTP supported: host[:port]/dir/file
573 ** NcFTP-compatible colon URL syntax for FTP supported: host:/dir/file
575 ** <base href="xxx"> supported
577 ** autoconf supported
