Tue Aug  4 1998   Gisle Aas <[email protected]>

 o  Release 5.36

 o  The lwp-download script will call $ua->env_proxy now.

 o  The lwp-request script allows content types (specified with the -c
    option) with optional parameters like: multipart/mixed; boundary="--".

 o  LWP::UserAgent will lowercase all authentication parameter names
    before passing it to the authentication module.  Previous releases
    ignored parameters like; Realm="Foo" (bacause Realm contained
    upper case letters).

 o  LWP::Protocol::ftp test for If-Modified-Since was wrong.

 o  How the $url->abs method works can now be configured with the global
    variables $URI::URL::ABS_ALLOW_RELATIVE_SCHEME and
    $URI::URL::ABS_REMOTE_LEADING_DOTS.

 o  The anonymous password guesser for ftp URLs will now call the external
    `whoami` program any more.  Patch by Charles C. Fu <[email protected]>.

 o  LWP::Protocol::http now allow dynamic requests without any
    Content-Length specified when Content-Type is multipart/*

    file modification time corresponding to the Last-Modified
    header.

 o  LWP::Protocol::http will not modify the HTTP::Request that

    redirects.

 o  URI::Heuristic and lwp-download documentation update.



Wed Apr 15 1998   Gisle Aas <[email protected]>

 o  Release 5.32

 o  Some HTML::Parser optimization tweaks.

 o  New module named HTML::Filter

 o  Updated HTTP::Headers to the latest HTTP spec.  Added knowledge
    about the "Trailer", "Expect", "TE", "Accept-Range" headers.

 o  Release 5.15

 o  New module URI::Heuristic

 o  The lwp-request script now use URI::Heuristic for it's URL arguments.
    It means that 'lwp-request perl' will not get a file called "./perl"
    but will fetch the page "http://www.perl.com" or something similar.
    If you want to get the file you have to prefix it with "./".  Full
    URLs are never affected by this.

 o  LWP::Simple::get() will bypass LWP for simple HTTP requests.  This
    should make it somewhat faster.

 o  LWP::RobotUA has a new method called $ua->use_sleep() that
    controls how niceness towards the servers are enforced.
    Previously $ua->use_alarm() used to control this, but this did
    not work well on Win32 systems.

 o  URI::URL::rel() will handle URLs to a fragment within the same
    document better. Initial patch from Nicolai Langfeldt
    <[email protected]>.

 o  HTML::Element don't consider </th>, </tr> and </td> optional any
    more.  I wonder how Netscape managed to not implement this
    correctly all this time.

 o  Added lots of modern tags to HTML::AsSubs.

 o  HTTP::Request::Common will read uploaded files in binmode().
    This should be better for Win32 systems.  Contributed by
    <[email protected]>.



Sun Oct 12 1997   Gisle Aas <[email protected]>

 o  Release 5.14

 o  HTML::Formatter patches from Andreas Gustafsson <[email protected]>.
    The formatters handling of whitespace is much better now.  Thanks!

 o  HTML::FormatText: can specify margins in the constructor.

 o  URI::URL: the base will be absolutized internally now.

 o  URI::URL will take advantage of void context provided by perl5.004.
    This means that using $u->path and $u->query should be safer now.

 o  URI::URL->print_on defaults to STDERR now (used to be STDOUT).

 o  URI::URL: removed version 3 compatibility stuff ($COMPAT_VER_3).

 o  $ua->mirror should work better on dosish systems (can not
    rename when target file exists).

 o  Typo in lwp-download prevented it from compiling.

 o  Some minor documentations typos corrected.



Sat Sep 20 1997   Gisle Aas <[email protected]>

 o  Release 5.13

 o  Brand new module called HTTP::Cookies.  It stores cookies
    (Set-Cookie and Set-Cookie2 headers) from responses and can
    create appropriate Cookie headers for requests.  It can also
    share cookie files with Netscape.

 o  LWP::UserAgent now support the cookie_jar() attribute.  When
    set to an HTTP::Cookies object, it will automatically manage
    the cookies sent to the servers.  Off by default.

 o  New header utility functions in HTTP::Headers::Util.

 o  Win32 and OS/2 patches for the lwp-xxx utilities.  Turn on
    binary mode by default (option to turn it off), avoid modifying $0,
    and don't be confused about suffixes in the script names.

    tests work even if perl is not called "perl"

 o  HTTP::Date handles 12:00PM correctly now. Patch from
    William York <[email protected]>

 o  HTTP::Request::Common don't quote the boundary string for
    multipart/form-data messages any more.

 o  Font::AFM works for encodings where .notdef is defined to
    have some size.  Documentation and efficiency update.

    HTTP::Header parameter.

 o  LWP::Protocol ensures that scheme is legal as module name.

 o  LWP::Protocol::http is not as strict when trying to verify the
    method name.  It now also accepts responses without a message
    on the status line.

 o  WWW::RobotRules::AnyDBM_File: Some DBMs fail to allow multiple
    opens of the same file.  Patch from Mark James <[email protected]>

 o  Created Bundle::LWP

    future.  It includes the new WWW::RobotRules::AnyDBM_File class
    and updates to LWP::RobotUA.

 o  HTML::Parser now supports buggy Netscape comment parsing.  Enable
    it by calling $p->netscape_buggy_comment(1).  The previous version
    of the parser could also (under very unlucky and unlikely
    circumstances) call the $self->comment() method several times for
    the same comment text.

 o  HTML::Parser: Use new $p->eof to signal end of document instead of
    $p->parse(undef).

 o  HTML::Element::starttag() is now smarter about which quotes it
    use around attribute values.

    is_fresh(), fresh_until().

 o  HTTP::Message:  New method ($mess->content_ref) which will return
    a reference to the current content.

 o  URI::URL:  New method ($url->rel) which does the opposite of abs().
    Example: url("http://host/a/b/c", "http://host/c/d/e")->rel would
    return url("../../a/b/c", "http://host/c/d/e").  This was
    suggested by Nicolai Langfeldt <[email protected]>

 o  Made $header->authorization_basic return "uname:passwd" in scalar
    context

 o  LWP::Protocol::collect() will let the HTML::HeadParser look at the
    document content as it arrives.  This will initialize headers from
    elements like <base href="...">, <title>...</title> and <meta
    http-equiv="..." ...>.

 o  Simplified $response->base implementation, because we don't have
    to look into the content any more.

 o  Implemented $protocol->collect_once() and simplified several
    of the protocol implementations by using it.

 o  The HTML parser used to get it wrong if you were unlucky about the
    breakup of the text. An example of broken behaviour was this:

    killed us.

 o  Added support for Digest Access Authentication.  Contributed by
    Doug MacEachern <[email protected]>.

    It also inserts a <BASE> tag in directories instead of a redirect.

 o  MIME::Base64 routines can be called as MIME::Base64::encode() and
    MIME::Base64::decode().  Same kind of thing for QuotedPrint.



Mon Nov  6 1995   Gisle Aas <[email protected]>

 o  Release 5b6

 o  Installation should work better for those that still runs
    perl4 as 'perl'.  The mirror script is not installed by
    default.

 o  LWP::Socket::_getaddress() Numerical IP adresses did not work.

 o  LWP::Socket::pushback() did not work.  This also avoids the bad
    pp_select() core dump from perl.

 o  LWP::IO now also selects on socket exceptions.

 o  HTML::Parse:  Ignore <!DOCTYPE ...> regardless for case.  Some
    bad insertElement() calls made infinite loops.

    completness sake.  Routine names has changed as suggested by Tim
    Bunce.

 o  LWP::MediaType reads default types from media.types file.
    guessMediaType() now also returns encodings.  New function mediaSuffix()

 o  Pass $url to $ua->getBasicCredentials().  This also fixes security
    hole with the old implementation of getBasicCredentials().

 o  LWP::Protocol::file now sets Content-Encoding headers

 o  Allow request content to be provided by a callback routine.

 o  Fix bug that prevented response callback to work.  The first parameter
    (data) is no longer a reference, because $_[0] is already a reference.
    Don't callback unless successful response.  Callbacks during redirects
    was confusing.

 o  URI::URL.  Remove port from netloc if it is the default port.
    Don't use anything, just require.

 o  HTTP::Message->addContent() does not need a reference parameter.

 o  LWP::Socket->open() has been renamed top LWP::Socket->connect()
    LWP::Socket->close has gone.  Implemented new method LWP::Socket->read()
    that returns as fast as it has some data to offer.  Implemented
    LWP::Socket->pushback().

    functions.

 o  Setting $url->scheme now changes the class of the object.

 o  Made $httpurl->user() and $httpurl->password() illegal.
    Likewise for other URL schemes.




Wed Aug  9 1995   Gisle Aas <[email protected]>

 o  Reorganisation as discussed on <[email protected]>
       LWP::Date       --> HTTP::Date
       LWP::MIMEheader --> HTTP::Headers
       LWP::StatusCode --> HTTP::Status
       LWP::Message    --> HTTP::Message
       LWP::Request    --> HTTP::Request
       LWP::Response   --> HTTP::Response
       LWP::MIMEtypes  --> LWP::MediaTypes

 o  HTTP::Date parses ctime format with missing timezone as suggested
    by Roy Fielding <[email protected]>

 o  HTTP::Status and LWP::MediaTypes exports their functions by default.

 o  Splitted up the URI::URL module.  Schemes are implemented by separate
    files that are autoloaded when used.  Self test moved to "t/uri.t".


       
Mon Aug  7 1995   Gisle Aas <[email protected]>

 o  Applied patch from Marc Hedlund <[email protected]>
       - Update the @header_order according to the August 3rd draft.
       - Added Response Header fields: 'Location', 'Public', 'Retry-After',
         'Server', and 'WWW-Authenticate'.
       - Moved 'unknown header' handling from &scan to &header. The old
         implementation was forcing all unknown header-words to begin with
     an uppercase (as it should be), but disallowed other uppercase
     letters.
       - updates the status code messages under the August
         3rd HTTP/1.0 draft.  '203' became 'Non-Authoritative Information',
     '303' became 'See Other', and a new code,
     '411 Authorization Refused', was added.

 o  Can remove multiple headers with single removeHeader() call in MIMEheader.

 o  Can assign multiple field/value pairs in header() method of MIMEheader.

 o  A field with multiple values is printed as separate values in
    MIMEheader::as_string().

 o  LWP::Response contain new attributes: previous() and request().  These
    attributes are updated by the UserAgent.

 o  Appended \n to some die statements in Socket so that line numbers are
    suppressed in error messages.

 o  Made UserAgent::clone work for reference members

 o  Check for redirect loops and multiple authorization failures by
    examination of the response chain.

 o  Use "\015\012" instead of "\r\n" in protocol modules.  Some systems
    define \r and \n differently.

 o  request program can now handle documents that needs autorization by
    prompting the user for username/password. Added new -S option to print
    request/response chain.
