* Changes in Wget 1.10.
10
** Downloading files larger than 2GB, sometimes referred to as "large
11
files", now works on systems that support them. This includes the
12
majority of modern Unixes, as well as MS Windows.
14
** IPv6 is now supported by Wget. Unlike the experimental code in
15
1.9, this version supports dual-family systems. The new flags
16
`--inet4' and `--inet6' (or `-4' and `-6' for short) force the use of
17
IPv4 and IPv6 respectively. Note that IPv6 support has not yet been
20
** Microsoft's proprietary "NTLM" method of HTTP authentication is now
21
supported. This authentication method is undocumented and only used
22
by IIS. Note that *proxy* authentication is not supported in this
23
release; you can only authenticate to the target web site.
25
** Wget no longer truncates partially downloaded files when download
26
has to start over because the server doesn't support Range. Instead,
27
with such servers Wget now simply ignores the data up to the byte
28
where the last attempt left off, and only then continues appending to
29
the file. That way the downloaded file never shrinks, and download
30
retries from servers without support for partial downloads work even
31
when downloading to stdout.
35
*** SSL/TLS downloads now attempt to verify the server's certificate
36
against the recognized certificate authorities. This requires CA
37
certificates to have been installed in a location visible to the
38
OpenSSL library. If this is not the case, you can get the bundle
39
yourself from a source you trust (for example, the bundle extracted
40
from Mozilla available at http://curl.haxx.se/docs/caextract.html),
41
and point Wget to the PEM file using the `--ca-certificate'
42
command-line option or the corresponding `.wgetrc' command.
44
*** Secure downloads now verify that the host name in the URL matches
45
the "common name" in the certificate presented by the server.
47
*** Although the above checks provide more secure downloads, they
48
unavoidably break interoperability with some sites that worked with
49
previous versions, particularly those using self-signed, expired, or
50
otherwise invalid certificates. If you encounter "certificate
51
verification" errors or complaints that "common name doesn't match
52
requested host name" and are convinced of the site's authenticity, you
53
can use `--no-check-certificate' to bypass both checks.
55
*** Talking to SSL/TLS servers over proxies now actually works.
56
Previous versions of Wget erroneously sent GET requests for https
57
URLs. Wget 1.10 utilizes the CONNECT method designed for this
60
*** The SSL/TLS-related options have been redesigned and, for the
61
first time, documented in the manual. The old, undocumented, options
62
are no longer supported.
64
** Passive FTP is now the default FTP transfer mode. Use
65
`--no-passive-ftp' or specify `passive_ftp = off' in your init file to
66
revert to the old behavior.
68
** The `--header' option can now be used to override generated
69
headers. For example, `wget --header="Host: foo.bar"
70
http://127.0.0.1' tells Wget to connect to localhost, but to specify
71
"foo.bar" in the `Host' header. In previous versions such use of
72
`--header' lead to duplicate headers in HTTP requests.
74
** The responses without headers, aka "HTTP 0.9" responses, are
75
detected and handled. Although HTTP 0.9 has long been obsolete, it is
76
still occasionally used, sometimes by accident.
78
** The progress bar is now updated regularly even when the data does
79
not arrive from the network.
81
** Wget no longer preserves permissions of files retrieved by FTP by
82
default. Anonymous FTP servers frequently use permissions like "664",
83
which might not be what the user wants. The new option
84
`--preserve-permissions' and the corresponding `.wgetrc' variable can
85
be used to revert to the old behavior.
87
** The new option `--protocol-directories' instructs Wget to also use
88
the protocol name as a directory component of local file names.
90
** Options that previously unconditionally set or unset various flags
91
are now boolean options that can be invoked as either `--OPTION' or
92
`--no-OPTION'. Options that required an argument "on" or "off" have
93
also been changed this way, but they still accept the old syntax for
94
backward compatibility. For example, instead of `--glob=off' you can
97
Allowing `--no-OPTION' for every `--OPTION' and the other way around
98
is useful because it allows the user to override non-default behavior
99
specified via `.wgetrc'.
101
** The new option `--keep-session-cookies' causes `--save-cookies' to
102
save session cookies (normally only kept in memory) along with the
103
permanent ones. This is useful because many sites track important
104
information, such as whether the user has authenticated, in session
105
cookies. With this option multiple Wget runs are treated as a single
108
** Wget now supports the --ftp-user and --ftp-password command
109
switches to set username and password for FTP, and the --user and
110
--password command switches to set username and password for both FTP
111
and HTTP. The --http-passwd and --proxy-passwd command switches have
112
been renamed to --http-password and --proxy-password respectively, and
113
the related http_passwd and proxy_passwd .wgetrc commands to
114
http_password and proxy_password respectively. The login and passwd
115
.wgetrc commands have been deprecated.
117
* `wget -b' now works correctly under Windows.

119
* Wget 1.9.1 is a bugfix release with no user-visible changes.
