PyUp Safety actively tracks 263,329 Python packages for vulnerabilities and notifies you when to upgrade.

Mechanize

0.4.5

* Add a set_html() method to the browser object
  
  2019-11-07 Kovid Goyal

0.4.4

* URLs passed into mechanize now automatically have URL unsafe characters
  percent encoded. This is necessary because newer versions of python
  disallow processing of URLs with unsafe characters. Note that this means
  values return by get_full_url(), get_selector() etc will be percent encoded.
  
  2019-08-18 Kovid Goyal

0.4.3

* When filling forms with unicode strings automatically encode them into
  the correct encoding fr the HTML page being viewed
  * Guess content type when uploading files if not specified
  * py3 compat - Have the version of simple cookies be 0 rather than None
  
  2019-04-12 Kovid Goyal

0.4.2

* A couple of python 3 specific fixes for proxy authorization and
  * adding controls to forms
  
  
  2019-03-16 Kovid Goyal

0.4.1

* A couple of python 3 specific fixes for servers with missing robots.txt
  files and also errors when using basic/digest auth
  
  
  2019-01-16 Kovid Goyal

0.4.0

* Python 3 compatibility
  * Add a finalize_request_headers callback to Browser to allow users full
  control of what headers are sent with every request

  where the default encoding is ascii.
  * Fix errors on python environments with broken threading
  
  2017-06-24 Kovid Goyal

  * Fix error when trying to open pages that contain HTML entities that
  decode to unicode characters in their <head> sections
  
  2017-05-05 Kovid Goyal

  2017-04-29 Kovid Goyal
  * 0.3.2 release.
  * Allow overriding of Host headers via addheaders
  * Fix using unicode strings in addheaders and trying to send data with a request failing
  
  2017-03-17 Kovid Goyal
  * 0.3.1 release.

  * Create full documentation at: https://mechanize.readthedocs.io/en/latest/
  
  2017-03-15 Kovid Goyal
  * 0.3.0 release.
  * Support HTML 5 (all html is now parsed using html5lib)
  * Implement cloning of browser instances via Browser.__copy__()
  * Make gzip content-encoding non-experimental. Always handle it if sent by the server, regardless of set_handle_gzip().
  * mechanize now requires python >= 2.7.0
  * When processing cookies that have a blank (unset) path, assume the path
  is /. Mimics modern browser behavior.
  * Support PyPy (added to continuous integration testing)
  * Make the global urlopen/urlretrieve methods threadsafe
  * Add support for user supplied CA certificates
  * Fix gzip not being requested on HTTPS connections
  * Normalize the case of HTTP headers in requests
  * Fix proxy authentication for https connections not working
  * Size of codebase reduced by 10,000 lines of code (40%)
  
  * Backward incompatibility: The factory keyword argument to Browser is no longer allowed
  * Backward incompatibility: Browser.forms() and Browser.links() return unicode strings instead of byte strings
  * Backward incompatibility: When searching for a form control if more than one control matches, an AmbiguityError is always raised
  * Backward incompatibility: There is no longer a mechanize.ParseError and mechanize.ParseResponse
  class. Parsing now uses the HTML 5 algorithm, which is designed to not fail on malformed markup.
  * Backward incompatibility: For links that do not have any text the text
  attribute is now always an empty string instead of None or an empty string.
  * Backward incompatibility: Remove support for the <isindex> HTML tag which was deprecated in HTML 4 and removed in HTML 5
  
  2011-03-31 John J Lee <jjlpobox.com>
  * 0.2.5 release.
  * This is essentially a no-changes release to fix easy_install
  breakage caused by a SourceForge issue
  * Sourceforge is returning invalid HTTP responses, make download
  links point to PyPI instead
  * Include cookietest.cgi in source distribution
  * Note new IETF cookie standardisation effort
  
  2010-10-28 John J Lee <jjlpobox.com>
  * 0.2.4 release.
  * Fix IndexError on empty Content-type header value. (GH-18)
  * Fall back to another encoding if an unknown one is declared.
  Fixes traceback on unknown encoding in Content-type header.
  (GH-30)
  
  2010-10-16 John J Lee <jjlpobox.com>
  * 0.2.3 release.
  * Fix str(ParseError()) traceback. (GH-25)
  * Add equality methods to mechanize.Cookie . (GH-29)
  
  2010-07-17 John J Lee <jjlpobox.com>
  * 0.2.2 release.
  * Officially support Python 2.7 (no changes were required)
  * Fix TypeError on .open()ing ftp: URL (only affects Python 2.4
  and 2.5)
  * Don't include HTTPSHandler in __all__ if it's not available
  
  2010-05-16 John J Lee <jjlpobox.com>
  * 0.2.1 release.
  * API change: Change argument order of
  HTTPRedirectHandler.redirect_request() to match urllib2.
  * Fix failure to use bundled BeautifulSoup for forms. (GH-15)
  * Fix default cookie path where request path has query containing
  / character. (http://bugs.python.org/issue3704)
  * Fix failure to raise on click for nonexistent label. (GH-16)
  * Documentation fixes.
  
  2010-04-22 John J Lee <jjlpobox.com>
  * 0.2.0 release.
  * Behaviour change: merged upstream urllib2 change (allegedly a
  "bug fix") to return a response for all 2** HTTP responses (e.g.
  206 Partial Content).  Previously, only 200 caused a response
  object to be returned.  All other HTTP response codes resulted
  in a response object being raised as an exception.
  * Behaviour change: Use of mechanize classes with `urllib2` (and
  vice-versa) is no longer supported.  However, existing classes
  implementing the urllib2 Handler interface are likely to work
  unchanged with mechanize.  Removed RequestUpgradeProcessor,
  ResponseUpgradeProcessor, SeekableProcessor.
  * ClientForm has been merged into mechanize.  This means that
  mechanize has no dependencies other than Python itself.  The
  ClientForm API is still available -- to switch from ClientForm to
  mechanize, just s/ClientForm/mechanize in your source code, and
  ensure any use of the module logging logger named "ClientForm" is
  updated to use the new logger name "mechanize.forms".  I probably
  won't do further standalone releases of ClientForm.
  * Stop monkey-patching Python stdlib.
  * Merge fixes from urllib2 trunk
  * Close file objects on .read() failure in .retrieve()
  * Fix a python 2.4 bug due to buggy urllib.splithost
  * Fix Python 2.4 syntax error in _firefox3cookiejar
  * Fix __init__.py typo that hid mechanize.seek_wrapped_response and
  mechanize.str2time.  Fixes
  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=465206
  * Fix an obvious bug with experimental firefox 3 cookiejar support.
  It's still experimental and not properly tested.
  * Change documentation to not require a .port attribute on request
  objects, since that's unused.
  * Doc fixes
  * Added mechanize.urljoin (RFC 3986 compliant function for joining
  a base URI with a URI reference)
  * Merge of ClientForm (see above).
  * Moved to git (from SVN) http://github.com/jjlee/mechanize
  * Created an issue tracker http://github.com/jjlee/mechanize/issues
  * Docs are now in markdown format (thanks John Gabriele).
  * Website rearranged.  The old website has been archived at
  http://wwwsearch.sourceforge.net/old/ .  The new website is
  essentially just the mechanize pages, rearranged and cleaned up a
  bit.
  * Source code rearranged for easier merging with upstream urllib2
  * Fully automated release process.
  * New test runner.  Single test suite; tests create their own HTTP
  server fixtures (server fixtures are cached where possible for
  speed).
  
  2009-02-07 John J Lee <jjlpobox.com>
  * 0.1.11 release.
  * Fix quadratic performance in number of .read() calls (and add an
  automated performance test).
  
  2008-12-03 John J Lee <jjlpobox.com>
  * 0.1.10 release.
  * Add support for Python 2.6: Raise URLError on file: URL errors,
  not IOError (port of upstream urllib2 fix).  Add support for
  Python 2.6's per-connection timeouts: Add timeout arguments to
  urlopen(), Request constructor, .open(), and .open_novisit().
  * Drop support for Python 2.3
  * Add Content-length header to Request object (httplib bug that
  prevented doing that was fixed in Python 2.4).  There's no
  change is what is actually sent over the wire here, just in what
  headers get added to the Request object.
  * Fix AttributeError on .retrieve() with a Request (as opposed to
  URL string) argument
  * Don't change CookieJar state in .make_cookies().
  * Fix AttributeError in case where .make_cookies() or
  .cookies_for_request() is called before other methods like
  .extract_cookies() or .make_cookie_header()
  * Fixes affecting version cookie-attribute
  (http://bugs.python.org/issue3924).
  * Silence module logging's "no handlers could be found for logger
  mechanize" warning in a way that doesn't clobber attempts to set
  log level sometimes
  * Don't use private attribute of request in request upgrade
  handler (what was I thinking??)
  * Don't call setup() on import of setup.py
  * Add new public function effective_request_host
  * Add .get_policy() method to CookieJar
  * Add method CookieJar.cookies_for_request()
  * Fix documented interface required of requests and responses (and
  add some tests for this!)
  * Allow either .is_unverifiable() or .unverifiable on request
  objects (preferring the former)
  * Note that there's a new functional test for digest auth, which
  fails when run against the sourceforge site (which is the
  default).  It looks like this reflects the fact that digest auth
  has been fairly broken since it was introduced in urllib2.  I
  don't plan to fix this myself.
  
  2008-09-24 John J Lee <jjlpobox.com>
  * 0.1.9 release.
  * Fix ImportError if sqlite3 not available
  * Fix a couple of functional tests not to wait 5 seconds each
  
  2008-09-13 John J Lee <jjlpobox.com>
  * 0.1.8 release.
  * Close sockets.  This only affects Python 2.5 (and later) -
  earlier versions of Python were unaffected.  See
  http://bugs.python.org/issue1627441
  * Make title parsing follow Firefox behaviour wrt child
  elements (previously the behaviour differed between Factory and
  RobustFactory).
  * Fix BeautifulSoup RobustLinksFactory (hence RobustFactory) link
  text parsing for case of link text containing tags (Titus Brown)
  * Fix issue where more tags after <title> caused default parser to
  raise an exception
  * Handle missing cookie max-age value.  Previously, a warning was
  emitted in this case.
  * Fix thoroughly broken digest auth (still need functional
  test!) (trebor74hr...)
  * Handle cookies containing embedded tabs in mozilla format files
  * Remove an assertion about mozilla format cookies file
  contents (raise LoadError instead)
  * Fix MechanizeRobotFileParser.set_opener()
  * Fix selection of global form using .select_form() (Titus Brown)
  * Log skipped Refreshes
  * Stop tests from clobbering files that happen to be lying around
  in cwd (!)
  * Use SO_REUSEADDR for local test server.
  * Raise exception if local test server fails to start.
  * Tests no longer (accidentally) depend on third-party coverage
  module
  * The usual docs and test fixes.
  * Add convenience method Browser.open_local_file(filename)
  * Add experimental support for Firefox 3 cookie jars
  ("cookies.sqlite").  Requires Python 2.5
  * Fix a _gzip.py NameError (gzip support is experimental)
  
  2007-05-31 John J Lee <jjlpobox.com>
  * 0.1.7b release.
  * Sub-requests should not usually be visiting, so make it so.  In
  fact the visible behaviour wasn't really broken here, since
  .back() skips over None responses (which is odd in itself, but
  won't be changed until after stable release is branched).
  However, this patch does change visible behaviour in that it
  creates new Request objects for sub-requests (e.g. basic auth
  retries) where previously we just mutated the existing Request
  object.
  * Changes to sort out abuse of by SeekableProcessor and
  ResponseUpgradeProcessor (latter shouldn't have been public in
  the first place) and resulting confusing / unclear / broken
  behaviour.  Deprecate SeekableProcessor and
  ResponseUpgradeProcessor.  Add SeekableResponseOpener.  Remove
  SeekableProcessor and ResponseUpgradeProcessor from Browser.
  Move UserAgentBase.add_referer_header() to Browser (it was on by
  default, breaking UserAgent, and should never really have been
  there).
  * Fix HTTP proxy support: r29110 meant that Request.get_selector()
  didn't take into account the change to .__r_host
  (Thanks tgates...).
  * Redirected robots.txt fetch no longer results in another
  attempted robots.txt fetch to check the redirection is allowed!
  * Fix exception raised by RFC 3986 implementation with
  urljoin(base, '/..')
  * Fix two multiple-response-wrapping bugs.
  * Add missing import in tests (caused failure on Windows).
  * Set svn:eol-style to native for all text files in SVN.
  * Add some tests for upgrade_response().
  * Add a functional test for 302 + 404 case.
  * Add an -l option to run the functional tests against a local
  twisted.web-based server (you need Twisted installed for this
  to work).  This is much faster than running against
  wwwsearch.sourceforge.net
  * Add -u switch to skip unittests (and only run the doctests).
  
  2007-01-07 John J Lee <jjlpobox.com>

0.1.6b

* Add mechanize.ParseError class, document it as part of the
  mechanize.Factory interface, and raise it from all Factory
  implementations.  This is backwards-compatible, since the new
  exception derives from the old exceptions.
  * Bug fix: Truncation when there is no full .read() before
  navigating to the next page, and an old response is read after
  navigation.  This happened e.g. with r = br.open();
  r.readline(); br.open(url); r.read(); br.back() .
  * Bug fix: when .back() caused a reload, it was returning the old
  response, not the .reload()ed one.
  * Bug fix: .back() was not returning a copy of the response, which
  presumably would cause seek position problems.
  * Bug fix: base tag without href attribute would override document
  URL with a None value, causing a crash (thanks Nathan Eror).
  * Fix .set_response() to close current response first.
  * Fix non-idempotent behaviour of Factory.forms() / .links() .
  Previously, if for example you got a ParseError during execution
  of .forms(), you could call it again and have it not raise an
  exception, because it started out where it left off!
  * Add a missing copy.copy() to RobustFactory .
  * Fix redirection to 'URIs' that contain characters that are not
  allowed in URIs (thanks Riko Wichmann).  Also, Request
  constructor now logs a module logging warning about any such bad
  URIs.
  * Add .global_form() method to Browser to support form controls
  whose HTML elements are not descendants of any FORM element.
  * Add a new method .visit_response() .  This creates a new history
  entry from a response object, rather than just changing the
  current visited response.  This is useful e.g. when you want to
  use Browser features in a handler.
  * Misc minor bug fixes.
  
  2006-10-25 John J Lee <jjlpobox.com>

0.1.5b

ClientForm>=0.2.5 (for an important bug fix affecting fragments
  in URLs).  There are no other changes in this release -- this
  release was done purely so that people upgrading to the latest
  version of mechanize will get the latest ClientForm too.
  
  2006-10-14 John J Lee <jjlpobox.com>

0.1.4b

reasons)
  * Improved auth & proxies support.
  * Follow RFC 3986.
  * Add a .set_cookie() method to Browser .
  * Add Browser.open_novisit() and Request.visit to allow fetching
  files without affecting Browser state.
  * UserAgent and Browser are now subclasses of UserAgentBase.
  UserAgent's only role in life above what UserAgentBase does is
  to provide the .set_seekable_responses() method (it lives there
  because Browser depends on seekable responses, because that's
  how browser history is implemented).
  * Bundle BeautifulSoup 2.1.1.  No more dependency pain!  Note that
  BeautifulSoup is, and always was, optional, and that mechanize
  will eventually switch to BeautifulSoup version 3, at which
  point it may well stop bundling BeautifulSoup.  Note also that
  the module is only used internally, and is not available as a
  public attribute of the package.  If you dare, you can import it
  ("from mechanize import _beautifulsoup"), but beware that it
  will go away later, and that the API of BeautifulSoup will
  change when the upgrade to 3 happens.  Also, BeautifulSoup
  support (mainly RobustFactory) is still a little experimental
  and buggy.
  * Fix HTTP-EQUIV with no content attribute case (thanks Pratik
  Dam).
  * Fix bug with quoted META Refresh URL (thanks Nilton Volpato).
  * Fix crash with </base> tag (yajdbgr02...).
  * Somebody found a server that (incorrectly) depends on HTTP
  header case, so follow the Title-Case convention.  Note that the
  Request headers interface(s), which were (somewhat oddly -- this
  is an inheritance from urllib2 that should really be fixed in a
  better way than it is currently) always case-sensitive still
  are; the only thing that changed is what actually eventually
  gets sent over the wire.
  * Use mechanize (not urllib) to open robots.txt.  Don't consult
  RobotFileParser instance about non-HTTP URLs.
  * Fix OpenerDirector.retrieve(), which was very broken (thanks
  Duncan Booth).
  * Crash in a much more obvious way if trying to use OpenerDirector
  after .close() .
  * .reload() on .back() if necessary (necessary iff response was
  not fully .read() on first .open()ing ) * Strip fragments before
  retrieving URLs (fixed Request.get_selector() to strip fragment)
  * Fix catching HTTPError subclasses while still preserving all
  their response behaviour
  * Correct over-enthusiastic documented guarantees of
  closeable_response .
  * Fix assumption that httplib.HTTPMessage treats dict-style
  __setitem__ as append rather than set (where on earth did I get
  that from?).
  * Expose History in mechanize/__init__.py (though interface is
  still experimental).
  * Lots of other "internals" bugs fixed (thanks to reports /
  patches from Benji York especially, also Titus Brown, Duncan
  Booth, and me ;-), where I'm not 100% sure exactly when they
  were introduced, so not listing them here in detail.
  * Numerous other minor fixes.
  * Some code cleanup.
  
  2006-05-21 John J Lee <jjlpobox.com>

0.1.2b

* mechanize now exports the whole urllib2 interface.
  * Pull in bugfixed auth/proxy support code from Python 2.5.
  * Bugfix: strip leading and trailing whitespace from link URLs
  * Fix .any_response() / .any_request() methods to have ordering.
  consistent with rest of handlers rather than coming before all
  of them.
  * Tell cookie-handling code about new TLDs.
  * Remove Browser.set_seekable_responses() (they always are
  anyway).
  * Show in web page examples how to munge responses and how to do
  proxy/auth.
  * Rename 0.1.* changes document 0.1.0-changes.txt -->
  0.1-changes.txt.
  * In 0.1 changes document, note change of logger name from
  "ClientCookie" to "mechanize"
  * Add something about response objects to changes document
  * Improve Browser.__str__
  * Accept regexp strings as well as regexp objects when finding
  links.
  * Add crappy gzip transfer encoding support.  This is off by
  default and warns if you turn it on (hopefully will get better
  later :-).
  * A bit of internal cleanup following merge with pullparser /
  ClientCookie.
  
  2006-05-06 John J Lee <jjlpobox.com>

0.1.1a

* Merge ClientCookie and pullparser with mechanize.
  * Response object fixes.
  * Remove accidental dependency on BeautifulSoup introduced in
  0.1.0a (the BeautifulSoup support is still here, but
  BeautifulSoup is not required to use mechanize).
  
  2006-05-03 John J Lee <jjlpobox.com>

0.1.0a

* Stop trying to record precise dates in changelog, since that's
  silly ;-)
  * A fair number of interface changes: see 0.1.0-changes.txt.
  * Depend on recent ClientCookie with copy.copy()able response
  objects.
  * Don't do broken XHTML handling by default (need to review code
  before switching this back on, e.g. should use a real XML parser
  for first-try at parsing).  To get the old behaviour, pass
  i_want_broken_xhtml_support=True to mechanize.DefaultFactory /
  .RobustFactory constructor.
  * Numerous small bug fixes.
  * Documentation & setup.py fixes.
  * Don't use cookielib, to avoid having to work around Python 2.4
  RFC 2109 bug, and to avoid my braindead thread synchronisation
  code in cookielib :-((((( (I haven't encountered specific
  breakage due to latter, but since it's braindead I may as well
  avoid it).
  
  2005-11-30 John J Lee <jjlpobox.com>
  * Fixed setuptools support.
  * Release 0.0.11a.
  
  2005-11-19 John J Lee <jjlpobox.com>
  * Release 0.0.10a.
  
  2005-11-17 John J Lee <jjlpobox.com>
  * Fix set_handle_referer.
  
  2005-11-12 John J Lee <jjlpobox.com>
  * Fix history (Gary Poster).
  * Close responses on reload (Gary Poster).
  * Don't depend on SSL support (Gary Poster).
  
  2005-10-31 John J Lee <jjlpobox.com>
  * Add setuptools support.
  
  2005-10-30 John J Lee <jjlpobox.com>
  * Don't mask AttributeError exception messages from ClientForm.
  * Document intent of .links() vs. .get_links_iter(); Rename
  LinksFactory method.
  * Remove pullparser import dependency.
  * Remove Browser.urltags (now an argument to LinksFactory).
  * Document Browser constructor as taking keyword args only (and
  change positional arg spec).
  * Cleanup of lazy parsing (may fix bugs, not sure...).
  
  2005-10-28 John J Lee <jjlpobox.com>
  * Support ClientForm backwards_compat switch.
  
  2005-08-28 John J Lee <jjlpobox.com>
  * Apply optimisation patch (Stephan Richter).
  
  2005-08-15 John J Lee <jjlpobox.com>
  * Close responses (ie. close the file handles but leave response
  still .read()able &c., thanks to the response objects we're
  using) (aurelnexedi.com).
  
  2005-08-14 John J Lee <jjlpobox.com>
  * Add missing argument to UserAgent's _add_referer_header stub.
  * Doc and comment improvements.
  
  2005-06-28 John J Lee <jjlpobox.com>
  * Allow specifying parser class for equiv handling.
  * Ensure correct default constructor args are passed to
  HTTPRefererProcessor.
  * Allow configuring details of Refresh handling.
  * Switch to tolerant parser.
  
  2005-06-11 John J Lee <jjlpobox.com>
  * Do .seek(0) after link parsing in a finally block.
  * Regard text/xhtml as HTML.
  * Fix 2.4-compatibility bugs.
  * Fix spelling of '_equiv' feature string.
  
  2005-05-30 John J Lee <jjlpobox.com>
  * Turn on Referer, Refresh and HTTP-Equiv handling by default.
  
  2005-05-08 John J Lee <jjlpobox.com>
  * Fix .reload() to not update history (thanks to Titus Brown).
  * Use cookielib where available
  
  2005-03-01 John J Lee <jjlpobox.com>
  * Fix referer bugs: Don't send URL fragments; Don't add in Referer
  header in redirected request unless original request had a
  Referer header.
  
  2005-02-19 John J Lee <jjlpobox.com>
  * Allow supplying own mechanize.FormsFactory, so eg. can use
  ClientForm.XHTMLFormParser.  Also allow supplying own Request
  class, and use sensible defaults for this.  Now depends on
  ClientForm 0.1.17.  Side effect is that, since we use the
  correct Request class by default, there's (I hope) no need for
  using RequestUpgradeProcessor in Browser._add_referer_header()
  :-)
  
  2005-01-30 John J Lee <jjlpobox.com>
  * Released 0.0.9a.
  
  2005-01-05 John J Lee <jjlpobox.com>
  * Fix examples (scraped sites have changed).
  * Fix .set_*() method boolean arguments.
  * The .response attribute is now a method, .response()
  * Don't depend on BaseProcessor (no longer exists).
  
  2004-05-18 John J Lee <jjlpobox.com>

0.0.8a

* Added robots.txt observance, controlled by
  * BASE element has attribute 'href', not 'uri'! (patch from Jochen
  Knuth)
  * Fixed several bugs in handling of Referer header.
  * Link.__eq__ now returns False instead of raising AttributeError
  on comparison with non-Link (patch from Jim Jewett)
  * Removed dependencies on HTTPS support in Python and on
  ClientCookie.HTTPRobotRulesProcessor
  
  2004-01-18 John J Lee <jjlpobox.com>
  * Added robots.txt observance, controlled by
  UserAgent.set_handle_robots().  This is now on by default.
  * Removed set_persistent_headers() method -- just use .addheaders,
  as in base class.
  
  2004-01-09 John J Lee <jjlpobox.com>
  * Removed unnecessary dependence on SSL support in Python.  Thanks
  to Krzysztof Kowalczyk for bug report.
  * Released 0.0.7a.
  
  2004-01-06 John J Lee <jjlpobox.com>
  * Link instances may now be passed to .click_link() and
  .follow_link().
  * Added a new example program, pypi.py.
  
  2004-01-05 John J Lee <jjlpobox.com>
  * Released 0.0.5a.
  * If <title> tag was missing, links and forms would not be parsed.
  Also, base element (giving base URI) was ignored.  Now parse
  title lazily, and get base URI while parsing links.  Also, fixed
  ClientForm to take note of base element.  Thanks to Phillip J.
  Eby for bug report.
  * Released 0.0.6a.

  * Fixed _useragent._replace_handler() to update self.handlers
  correctly.
  * Updated required pullparser version check.
  * Visiting a URL now deselects form (sets self.form to None).
  * Only first Content-Type header is now checked by
  ._viewing_html(), if there are more than one.
  * Stopped using getheaders from ClientCookie -- don't need it,
  since depend on Python 2.2, which has .getheaders() method on
  responses.  Improved comments.
  * .open() now resets .response to None.  Also rearranged .open() a
  bit so instance remains in consistent state on failure.
  * .geturl() now checks for non-None .response, and raises Browser.
  * .back() now checks for non-None .response, and doesn't attempt
  to parse if it's None.
  * .reload() no longer adds new history item.
  * Documented tag argument to .find_link().
  * Fixed a few places where non-keyword arguments for .find_link()
  were silently ignored.  Now raises ValueError.

  * Use response_seek_wrapper instead of seek_wrapper, which broke
  use of reponses after they're closed.
  * (Fixed response_seek_wrapper in ClientCookie.)
  * Fixed adding of Referer header.  Thanks to Per Cederqvist for
  bug report.
  * Released 0.0.4a.
  * Updated required ClientCookie version check.

  * Added support for character encodings (for matching link text).
  * Released 0.0.3a.
  
  2003-12-28 John J Lee <jjlpobox.com>
  * Attribute lookups are no longer forwarded to .response --
  you have to do it explicitly.
  * Added .geturl() method, which just delegates to .response.
  * Big rehash of UserAgent, which was broken.  Added a test.
  * Discovered that zip() doesn't raise an exception when its
  arguments are of different length, so several tests could pass
  when they should have failed.  Fixed.
  * Fixed <A/> case in ._parse_html().
  * Released 0.0.2a.
  
  2003-12-27 John J Lee <jjlpobox.com>
  * Added and improved docstrings.
  * Browser.form is now a public attribute.  Also documented
  Browser's public attributes.
  * Added base_url and absolute_url attributes to Link.
  * Tidied up .open().  Relative URL Request objects are no longer
  converted to absolute URLs -- they should probably be absolute
  in the first place anyway.
  * Added proper Referer handling (the handler in ClientCookie is a
  hack that only covers a restricted case).
  * Added click_link method, for symmetry with .click() / .submit()
  methods (which latter apply to forms).  Of these methods,
  .click/.click_link() returns a request, and .submit/
  .follow_link() actually .open()s the request.
  * Updated broken example code.
  
  2003-12-24 John J Lee <jjlpobox.com>
  * Modified setup.py so can easily register with PyPI.
  
  2003-12-22 John J Lee <jjlpobox.com>
  * Released 0.0.1a.
