-"""
-BitBake 'Fetch' implementation for Go modules
-
-The gomod/gomodgit fetchers are used to download Go modules to the module cache
-from a module proxy or directly from a version control repository.
-
-Example SRC_URI:
-
-SRC_URI += "gomod://golang.org/x/net;version=v0.9.0;sha256sum=..."
-SRC_URI += "gomodgit://golang.org/x/net;version=v0.9.0;repo=go.googlesource.com/net;srcrev=..."
-
-Required SRC_URI parameters:
-
-- version
-    The version of the module.
-
-Optional SRC_URI parameters:
-
-- mod
-    Fetch and unpack the go.mod file only instead of the complete module.
-    The go command may need to download go.mod files for many different modules
-    when computing the build list, and go.mod files are much smaller than
-    module zip files.
-    The default is "0", set mod=1 for the go.mod file only.
-
-- sha256sum
-    The checksum of the module zip file, or the go.mod file in case of fetching
-    only the go.mod file. Alternatively, set the SRC_URI varible flag for
-    "module@version.sha256sum".
-
-- protocol
-    The method used when fetching directly from a version control repository.
-    The default is "https" for git.
-
-- repo
-    The URL when fetching directly from a version control repository. Required
-    when the URL is different from the module path.
-
-- srcrev
-    The revision identifier used when fetching directly from a version control
-    repository. Alternatively, set the SRCREV varible for "module@version".
-
-- subdir
-    The module subdirectory when fetching directly from a version control
-    repository. Required when the module is not located in the root of the
-    repository.
-
-Related variables:
-
-- GO_MOD_PROXY
-    The module proxy used by the fetcher.
-
-- GO_MOD_CACHE_DIR
-    The directory where the module cache is located.
-    This must match the exported GOMODCACHE variable for the go command to find
-    the downloaded modules.
-
-See the Go modules reference, https://go.dev/ref/mod, for more information
-about the module cache, module proxies and version control systems.

-= 4.12.3 (20240117)
-
-* The Beautiful Soup documentation now has a Spanish translation, thanks
-  to Carlos Romero. Delong Wang's Chinese translation has been updated
-  to cover Beautiful Soup 4.12.0.
-
-* Fixed a regression such that if you set .hidden on a tag, the tag
-  becomes invisible but its contents are still visible. User manipulation
-  of .hidden is not a documented or supported feature, so don't do this,
-  but it wasn't too difficult to keep the old behavior working.
-
-* Fixed a case found by Mengyuhan where html.parser giving up on
-  markup would result in an AssertionError instead of a
-  ParserRejectedMarkup exception.
-
-* Added the correct stacklevel to instances of the XMLParsedAsHTMLWarning.
-  [bug=2034451]
-
-* Corrected the syntax of the license definition in pyproject.toml. Patch
-  by Louis Maddox. [bug=2032848]
-
-* Corrected a typo in a test that was causing test failures when run against
-  libxml2 2.12.1. [bug=2045481]
-
-= 4.12.2 (20230407)
-
-* Fixed an unhandled exception in BeautifulSoup.decode_contents
-  and methods that call it. [bug=2015545]
-
-= 4.12.1 (20230405)
-
-NOTE: the following things are likely to be dropped in the next
-feature release of Beautiful Soup:
-
- Official support for Python 3.6.
- Inclusion of unit tests and test data in the wheel file.
- Two scripts: demonstrate_parser_differences.py and test-all-versions.
-
-Changes:
-
-* This version of Beautiful Soup replaces setup.py and setup.cfg
-  with pyproject.toml. Beautiful Soup now uses tox as its test backend
-  and hatch to do builds.
-
-* The main functional improvement in this version is a nonrecursive technique
-  for regenerating a tree. This technique is used to avoid situations where,
-  in previous versions, doing something to a very deeply nested tree
-  would overflow the Python interpreter stack:
-
-  1. Outputting a tree as a string, e.g. with
-     BeautifulSoup.encode() [bug=1471755]
-
-  2. Making copies of trees (copy.copy() and
-     copy.deepcopy() from the Python standard library). [bug=1709837]
-
-  3. Pickling a BeautifulSoup object. (Note that pickling a Tag
-     object can still cause an overflow.)
-
-* Making a copy of a BeautifulSoup object no longer parses the
-  document again, which should improve performance significantly.
-
-* When a BeautifulSoup object is unpickled, Beautiful Soup now
-  tries to associate an appropriate TreeBuilder object with it.
-
-* Tag.prettify() will now consistently end prettified markup with
-  a newline.
-
-* Added unit tests for fuzz test cases created by third
-  parties. Some of these tests are skipped since they point
-  to problems outside of Beautiful Soup, but this change
-  puts them all in one convenient place.
-
-* PageElement now implements the known_xml attribute. (This was technically
-  a bug, but it shouldn't be an issue in normal use.) [bug=2007895]
-
-* The demonstrate_parser_differences.py script was still written in
-  Python 2. I've converted it to Python 3, but since no one has
-  mentioned this over the years, it's a sign that no one uses this
-  script and it's not serving its purpose.
-
-= 4.12.0 (20230320)
-
-* Introduced the .css property, which centralizes all access to
-  the Soup Sieve API. This allows Beautiful Soup to give direct
-  access to as much of Soup Sieve that makes sense, without cluttering
-  the BeautifulSoup and Tag classes with a lot of new methods.
-
-  This does mean one addition to the BeautifulSoup and Tag classes
-  (the .css property itself), so this might be a breaking change if you
-  happen to use Beautiful Soup to parse XML that includes a tag called
-  <css>. In particular, code like this will stop working in 4.12.0:
-
-    soup.css['id']
-
-  Code like this will work just as before:
-
-    soup.find_one('css')['id']
-
-  The Soup Sieve methods supported through the .css property are
-  select(), select_one(), iselect(), closest(), match(), filter(),
-  escape(), and compile(). The BeautifulSoup and Tag classes still
-  support the select() and select_one() methods; they have not been
-  deprecated, but they have been demoted to convenience methods.
-
-  [bug=2003677]
-
-* When the html.parser parser decides it can't parse a document, Beautiful
-  Soup now consistently propagates this fact by raising a
-  ParserRejectedMarkup error. [bug=2007343]
-
-* Removed some error checking code from diagnose(), which is redundant with
-  similar (but more Pythonic) code in the BeautifulSoup constructor.
-  [bug=2007344]
-
-* Added intersphinx references to the documentation so that other
-  projects have a target to point to when they reference Beautiful
-  Soup classes. [bug=1453370]
-
-= 4.11.2 (20230131)
-
-* Fixed test failures caused by nondeterministic behavior of
-  UnicodeDammit's character detection, depending on the platform setup.
-  [bug=1973072]
-
-* Fixed another crash when overriding multi_valued_attributes and using the
-  html5lib parser. [bug=1948488]
-
-* The HTMLFormatter and XMLFormatter constructors no longer return a
-  value. [bug=1992693]
-
-* Tag.interesting_string_types is now propagated when a tag is
-  copied. [bug=1990400]
-
-* Warnings now do their best to provide an appropriate stacklevel,
-  improving the usefulness of the message. [bug=1978744]
-
-* Passing a Tag's .contents into PageElement.extend() now works the
-  same way as passing the Tag itself.
-
-* Soup Sieve tests will be skipped if the library is not installed.
-
-= 4.11.1 (20220408)
-
-This release was done to ensure that the unit tests are packaged along
-with the released source. There are no functionality changes in this
-release, but there are a few other packaging changes:
-
-* The Japanese and Korean translations of the documentation are included.
-* The changelog is now packaged as CHANGELOG, and the license file is
-  packaged as LICENSE. NEWS.txt and COPYING.txt are still present,
-  but may be removed in the future.
-* TODO.txt is no longer packaged, since a TODO is not relevant for released
-  code.
-
-= 4.11.0 (20220407)
-
-* Ported unit tests to use pytest.
-
-* Added special string classes, RubyParenthesisString and RubyTextString,
-  to make it possible to treat ruby text specially in get_text() calls.
-  [bug=1941980]
-
-* It's now possible to customize the way output is indented by
-  providing a value for the 'indent' argument to the Formatter
-  constructor. The 'indent' argument works very similarly to the
-  argument of the same name in the Python standard library's
-  json.dump() function. [bug=1955497]
-
-* If the charset-normalizer Python module
-  (https://pypi.org/project/charset-normalizer/) is installed, Beautiful
-  Soup will use it to detect the character sets of incoming documents.
-  This is also the module used by newer versions of the Requests library.
-  For the sake of backwards compatibility, chardet and cchardet both take
-  precedence if installed. [bug=1955346]
-
-* Added a workaround for an lxml bug
-  (https://bugs.launchpad.net/lxml/+bug/1948551) that causes
-  problems when parsing a Unicode string beginning with BYTE ORDER MARK.
-  [bug=1947768]
-
-* Issue a warning when an HTML parser is used to parse a document that
-  looks like XML but not XHTML. [bug=1939121]
-
-* Do a better job of keeping track of namespaces as an XML document is
-  parsed, so that CSS selectors that use namespaces will do the right
-  thing more often. [bug=1946243]
-
-* Some time ago, the misleadingly named "text" argument to find-type
-  methods was renamed to the more accurate "string." But this supposed
-  "renaming" didn't make it into important places like the method
-  signatures or the docstrings. That's corrected in this
-  version. "text" still works, but will give a DeprecationWarning.
-  [bug=1947038]
-
-* Fixed a crash when pickling a BeautifulSoup object that has no
-  tree builder. [bug=1934003]
-
-* Fixed a crash when overriding multi_valued_attributes and using the
-  html5lib parser. [bug=1948488]
-
-* Standardized the wording of the MarkupResemblesLocatorWarning
-  warnings to omit untrusted input and make the warnings less
-  judgmental about what you ought to be doing. [bug=1955450]
-
-* Removed support for the iconv_codec library, which doesn't seem
-  to exist anymore and was never put up on PyPI. (The closest
-  replacement on PyPI, iconv_codecs, is GPL-licensed, so we can't use
-  it--it's also quite old.)
-
-= 4.10.0 (20210907)
-
-* This is the first release of Beautiful Soup to only support Python
-  3. I dropped Python 2 support to maintain support for newer versions
-  (58 and up) of setuptools. See:
-  https://github.com/pypa/setuptools/issues/2769 [bug=1942919]
-
-* The behavior of methods like .get_text() and .strings now differs
-  depending on the type of tag. The change is visible with HTML tags
-  like <script>, <style>, and <template>. Starting in 4.9.0, methods
-  like get_text() returned no results on such tags, because the
-  contents of those tags are not considered 'text' within the document
-  as a whole.
-
-  But a user who calls script.get_text() is working from a different
-  definition of 'text' than a user who calls div.get_text()--otherwise
-  there would be no need to call script.get_text() at all. In 4.10.0,
-  the contents of (e.g.) a <script> tag are considered 'text' during a
-  get_text() call on the tag itself, but not considered 'text' during
-  a get_text() call on the tag's parent.
-
-  Because of this change, calling get_text() on each child of a tag
-  may now return a different result than calling get_text() on the tag
-  itself. That's because different tags now have different
-  understandings of what counts as 'text'. [bug=1906226] [bug=1868861]
-
-* NavigableString and its subclasses now implement the get_text()
-  method, as well as the properties .strings and
-  .stripped_strings. These methods will either return the string
-  itself, or nothing, so the only reason to use this is when iterating
-  over a list of mixed Tag and NavigableString objects. [bug=1904309]
-
-* The 'html5' formatter now treats attributes whose values are the
-  empty string as HTML boolean attributes. Previously (and in other
-  formatters), an attribute value must be set as None to be treated as
-  a boolean attribute. In a future release, I plan to also give this
-  behavior to the 'html' formatter. Patch by Isaac Muse. [bug=1915424]
-
-* The 'replace_with()' method now takes a variable number of arguments,
-  and can be used to replace a single element with a sequence of elements.
-  Patch by Bill Chandos. [rev=605]
-
-* Corrected output when the namespace prefix associated with a
-  namespaced attribute is the empty string, as opposed to
-  None. [bug=1915583]
-
-* Performance improvement when processing tags that speeds up overall
-  tree construction by 2%. Patch by Morotti. [bug=1899358]
-
-* Corrected the use of special string container classes in cases when a
-  single tag may contain strings with different containers; such as
-  the <template> tag, which may contain both TemplateString objects
-  and Comment objects. [bug=1913406]
-
-* The html.parser tree builder can now handle named entities
-  found in the HTML5 spec in much the same way that the html5lib
-  tree builder does. Note that the lxml HTML tree builder doesn't handle
-  named entities this way. [bug=1924908]
-
-* Added a second way to pass specify encodings to UnicodeDammit and
-  EncodingDetector, based on the order of precedence defined in the
-  HTML5 spec, starting at:
-  https://html.spec.whatwg.org/multipage/parsing.html#parsing-with-a-known-character-encoding
-
-  Encodings in 'known_definite_encodings' are tried first, then
-  byte-order-mark sniffing is run, then encodings in 'user_encodings'
-  are tried. The old argument, 'override_encodings', is now a
-  deprecated alias for 'known_definite_encodings'.
-
-  This changes the default behavior of the html.parser and lxml tree
-  builders, in a way that may slightly improve encoding
-  detection but will probably have no effect. [bug=1889014]
-
-* Improve the warning issued when a directory name (as opposed to
-  the name of a regular file) is passed as markup into the BeautifulSoup
-  constructor. [bug=1913628]
-
-= 4.9.3 (20201003)
-
-This is the final release of Beautiful Soup to support Python
-2. Beautiful Soup's official support for Python 2 ended on 01 January,
-2021. In the Launchpad Git repository, the final revision to support
-Python 2 was revision 70f546b1e689a70e2f103795efce6d261a3dadf7; it is
-tagged as "python2".
-
-* Implemented a significant performance optimization to the process of
-  searching the parse tree. Patch by Morotti. [bug=1898212]
-
-= 4.9.2 (20200926)
-
-* Fixed a bug that caused too many tags to be popped from the tag
-  stack during tree building, when encountering a closing tag that had
-  no matching opening tag. [bug=1880420]
-
-* Fixed a bug that inconsistently moved elements over when passing
-  a Tag, rather than a list, into Tag.extend(). [bug=1885710]
-
-* Specify the soupsieve dependency in a way that complies with
-  PEP 508. Patch by Mike Nerone. [bug=1893696]
-
-* Change the signatures for BeautifulSoup.insert_before and insert_after
-  (which are not implemented) to match PageElement.insert_before and
-  insert_after, quieting warnings in some IDEs. [bug=1897120]
-
-= 4.9.1 (20200517)
-
-* Added a keyword argument 'on_duplicate_attribute' to the
-  BeautifulSoupHTMLParser constructor (used by the html.parser tree
-  builder) which lets you customize the handling of markup that
-  contains the same attribute more than once, as in:
-  <a href="url1" href="url2"> [bug=1878209]
-
-* Added a distinct subclass, GuessedAtParserWarning, for the warning
-  issued when BeautifulSoup is instantiated without a parser being
-  specified. [bug=1873787]
-
-* Added a distinct subclass, MarkupResemblesLocatorWarning, for the
-  warning issued when BeautifulSoup is instantiated with 'markup' that
-  actually seems to be a URL or the path to a file on
-  disk. [bug=1873787]
-
-* The new NavigableString subclasses (Stylesheet, Script, and
-  TemplateString) can now be imported directly from the bs4 package.
-
-* If you encode a document with a Python-specific encoding like
-  'unicode_escape', that encoding is no longer mentioned in the final
-  XML or HTML document. Instead, encoding information is omitted or
-  left blank. [bug=1874955]
-
-* Fixed test failures when run against soupselect 2.0. Patch by Tomáš
-  Chvátal. [bug=1872279]
-
-= 4.9.0 (20200405)
-
-* Added PageElement.decomposed, a new property which lets you
-  check whether you've already called decompose() on a Tag or
-  NavigableString.
-
-* Embedded CSS and Javascript is now stored in distinct Stylesheet and
-  Script tags, which are ignored by methods like get_text() since most
-  people don't consider this sort of content to be 'text'. This
-  feature is not supported by the html5lib treebuilder. [bug=1868861]
-
-* Added a Russian translation by 'authoress' to the repository.
-
-* Fixed an unhandled exception when formatting a Tag that had been
-  decomposed.[bug=1857767]
-
-* Fixed a bug that happened when passing a Unicode filename containing
-  non-ASCII characters as markup into Beautiful Soup, on a system that
-  allows Unicode filenames. [bug=1866717]
-
-* Added a performance optimization to PageElement.extract(). Patch by
-  Arthur Darcet.
-
-= 4.8.2 (20191224)
-
-* Added Python docstrings to all public methods of the most commonly
-  used classes.
-
-* Added a Chinese translation by Deron Wang and a Brazilian Portuguese
-  translation by Cezar Peixeiro to the repository.
-
-* Fixed two deprecation warnings. Patches by Colin
-  Watson and Nicholas Neumann. [bug=1847592] [bug=1855301]
-
-* The html.parser tree builder now correctly handles DOCTYPEs that are
-  not uppercase. [bug=1848401]
-
-* PageElement.select() now returns a ResultSet rather than a regular
-  list, making it consistent with methods like find_all().
-
-= 4.8.1 (20191006)
-
-* When the html.parser or html5lib parsers are in use, Beautiful Soup
-  will, by default, record the position in the original document where
-  each tag was encountered. This includes line number (Tag.sourceline)
-  and position within a line (Tag.sourcepos).  Based on code by Chris
-  Mayo. [bug=1742921]
-
-* When instantiating a BeautifulSoup object, it's now possible to
-   provide a dictionary ('element_classes') of the classes you'd like to be
-   instantiated instead of Tag, NavigableString, etc.
-
-* Fixed the definition of the default XML namespace when using
-   lxml 4.4. Patch by Isaac Muse. [bug=1840141]
-
-* Fixed a crash when pretty-printing tags that were not created
-   during initial parsing. [bug=1838903]
-
-* Copying a Tag preserves information that was originally obtained from
-   the TreeBuilder used to build the original Tag. [bug=1838903]
-
-* Raise an explanatory exception when the underlying parser
-   completely rejects the incoming markup. [bug=1838877]
-
-* Avoid a crash when trying to detect the declared encoding of a
-   Unicode document. [bug=1838877]
-
-* Avoid a crash when unpickling certain parse trees generated
-   using html5lib on Python 3. [bug=1843545]
-
-= 4.8.0 (20190720, "One Small Soup")
-
-This release focuses on making it easier to customize Beautiful Soup's
-input mechanism (the TreeBuilder) and output mechanism (the Formatter).
-
-* You can customize the TreeBuilder object by passing keyword
-  arguments into the BeautifulSoup constructor. Those keyword
-  arguments will be passed along into the TreeBuilder constructor.
-
-  The main reason to do this right now is to change how which
-  attributes are treated as multi-valued attributes (the way 'class'
-  is treated by default). You can do this with the
-  'multi_valued_attributes' argument. [bug=1832978]
-
-* The role of Formatter objects has been greatly expanded. The Formatter
-  class now controls the following:
-
-  - The function to call to perform entity substitution. (This was
-    previously Formatter's only job.)
-  - Which tags should be treated as containing CDATA and have their
-    contents exempt from entity substitution.
-  - The order in which a tag's attributes are output. [bug=1812422]
-  - Whether or not to put a '/' inside a void element, e.g. '<br/>' vs '<br>'
-
-  All preexisting code should work as before.
-
-* Added a new method to the API, Tag.smooth(), which consolidates
-  multiple adjacent NavigableString elements. [bug=1697296]
-
-* &apos; (which is valid in XML, XHTML, and HTML 5, but not HTML 4) is always
-  recognized as a named entity and converted to a single quote. [bug=1818721]
-
-= 4.7.1 (20190106)
-
-* Fixed a significant performance problem introduced in 4.7.0. [bug=1810617]
-
-* Fixed an incorrectly raised exception when inserting a tag before or
-  after an identical tag. [bug=1810692]
-
-* Beautiful Soup will no longer try to keep track of namespaces that
-  are not defined with a prefix; this can confuse soupselect. [bug=1810680]
-
-* Tried even harder to avoid the deprecation warning originally fixed in
-   4.6.1. [bug=1778909]
-
-= 4.7.0 (20181231)
-
-* Beautiful Soup's CSS Selector implementation has been replaced by a
-  dependency on Isaac Muse's SoupSieve project (the soupsieve package
-  on PyPI). The good news is that SoupSieve has a much more robust and
-  complete implementation of CSS selectors, resolving a large number
-  of longstanding issues. The bad news is that from this point onward,
-  SoupSieve must be installed if you want to use the select() method.
-
-  You don't have to change anything lf you installed Beautiful Soup
-  through pip (SoupSieve will be automatically installed when you
-  upgrade Beautiful Soup) or if you don't use CSS selectors from
-  within Beautiful Soup.
-
-  SoupSieve documentation: https://facelessuser.github.io/soupsieve/
-
-* Added the PageElement.extend() method, which works like list.append().
-   [bug=1514970]
-
-* PageElement.insert_before() and insert_after() now take a variable
-   number of arguments. [bug=1514970]
-
-* Fix a number of problems with the tree builder that caused
-  trees that were superficially okay, but which fell apart when bits
-  were extracted. Patch by Isaac Muse. [bug=1782928,1809910]
-
-* Fixed a problem with the tree builder in which elements that
-  contained no content (such as empty comments and all-whitespace
-  elements) were not being treated as part of the tree. Patch by Isaac
-  Muse. [bug=1798699]
-
-* Fixed a problem with multi-valued attributes where the value
-  contained whitespace. Thanks to Jens Svalgaard for the
-  fix. [bug=1787453]
-
-* Clarified ambiguous license statements in the source code. Beautiful
-  Soup is released under the MIT license, and has been since 4.4.0.
-
-* This file has been renamed from NEWS.txt to CHANGELOG.
-
-= 4.6.3 (20180812)
-
-* Exactly the same as 4.6.2. Re-released to make the README file
-  render properly on PyPI.
-
-= 4.6.2 (20180812)
-
-* Fix an exception when a custom formatter was asked to format a void
-  element. [bug=1784408]
-
-= 4.6.1 (20180728)
-
-* Stop data loss when encountering an empty numeric entity, and
-  possibly in other cases.  Thanks to tos.kamiya for the fix. [bug=1698503]
-
-* Preserve XML namespaces introduced inside an XML document, not just
-   the ones introduced at the top level. [bug=1718787]
-
-* Added a new formatter, "html5", which represents void elements
-   as "<element>" rather than "<element/>".  [bug=1716272]
-
-* Fixed a problem where the html.parser tree builder interpreted
-  a string like "&foo " as the character entity "&foo;"  [bug=1728706]
-
-* Correctly handle invalid HTML numeric character entities like &#147;
-  which reference code points that are not Unicode code points. Note
-  that this is only fixed when Beautiful Soup is used with the
-  html.parser parser -- html5lib already worked and I couldn't fix it
-  with lxml.  [bug=1782933]
-
-* Improved the warning given when no parser is specified. [bug=1780571]
-
-* When markup contains duplicate elements, a select() call that
-  includes multiple match clauses will match all relevant
-  elements. [bug=1770596]
-
-* Fixed code that was causing deprecation warnings in recent Python 3
-  versions. Includes a patch from Ville Skyttä. [bug=1778909] [bug=1689496]
-
-* Fixed a Windows crash in diagnose() when checking whether a long
-  markup string is a filename. [bug=1737121]
-
-* Stopped HTMLParser from raising an exception in very rare cases of
-  bad markup. [bug=1708831]
-
-* Fixed a bug where find_all() was not working when asked to find a
-  tag with a namespaced name in an XML document that was parsed as
-  HTML. [bug=1723783]
-
-* You can get finer control over formatting by subclassing
-  bs4.element.Formatter and passing a Formatter instance into (e.g.)
-  encode(). [bug=1716272]
-
-* You can pass a dictionary of `attrs` into
-  BeautifulSoup.new_tag. This makes it possible to create a tag with
-  an attribute like 'name' that would otherwise be masked by another
-  argument of new_tag. [bug=1779276]
-
-* Clarified the deprecation warning when accessing tag.fooTag, to cover
-  the possibility that you might really have been looking for a tag
-  called 'fooTag'.
-
-= 4.6.0 (20170507) =
-
-* Added the `Tag.get_attribute_list` method, which acts like `Tag.get` for
-  getting the value of an attribute, but which always returns a list,
-  whether or not the attribute is a multi-value attribute. [bug=1678589]
-
-* It's now possible to use a tag's namespace prefix when searching,
-  e.g. soup.find('namespace:tag') [bug=1655332]
-
-* Improved the handling of empty-element tags like <br> when using the
-  html.parser parser. [bug=1676935]
-
-* HTML parsers treat all HTML4 and HTML5 empty element tags (aka void
-  element tags) correctly. [bug=1656909]
-
-* Namespace prefix is preserved when an XML tag is copied. Thanks
-  to Vikas for a patch and test. [bug=1685172]
-
-= 4.5.3 (20170102) =
-
-* Fixed foster parenting when html5lib is the tree builder. Thanks to
-  Geoffrey Sneddon for a patch and test.
-  
-* Fixed yet another problem that caused the html5lib tree builder to
-  create a disconnected parse tree. [bug=1629825]
-
-= 4.5.2 (20170102) =
-
-* Apart from the version number, this release is identical to
-  4.5.3. Due to user error, it could not be completely uploaded to
-  PyPI. Use 4.5.3 instead.
-
-= 4.5.1 (20160802) =
-
-* Fixed a crash when passing Unicode markup that contained a
-  processing instruction into the lxml HTML parser on Python
-  3. [bug=1608048]
-
-= 4.5.0 (20160719) =
-
-* Beautiful Soup is no longer compatible with Python 2.6. This
-  actually happened a few releases ago, but it's now official.
-
-* Beautiful Soup will now work with versions of html5lib greater than
-  0.99999999. [bug=1603299]
-
-* If a search against each individual value of a multi-valued
-  attribute fails, the search will be run one final time against the
-  complete attribute value considered as a single string. That is, if
-  a tag has class="foo bar" and neither "foo" nor "bar" matches, but
-  "foo bar" does, the tag is now considered a match.
-
-  This happened in previous versions, but only when the value being
-  searched for was a string. Now it also works when that value is
-  a regular expression, a list of strings, etc. [bug=1476868]
-
-* Fixed a bug that deranged the tree when a whitespace element was
-  reparented into a tag that contained an identical whitespace
-  element. [bug=1505351]
-
-* Added support for CSS selector values that contain quoted spaces,
-  such as tag[style="display: foo"]. [bug=1540588]
-
-* Corrected handling of XML processing instructions. [bug=1504393]
-
-* Corrected an encoding error that happened when a BeautifulSoup
-  object was copied. [bug=1554439]
-
-* The contents of <textarea> tags will no longer be modified when the
-  tree is prettified. [bug=1555829]
-
-* When a BeautifulSoup object is pickled but its tree builder cannot
-  be pickled, its .builder attribute is set to None instead of being
-  destroyed. This avoids a performance problem once the object is
-  unpickled. [bug=1523629]
-
-* Specify the file and line number when warning about a
-  BeautifulSoup object being instantiated without a parser being
-  specified. [bug=1574647]
-
-* The `limit` argument to `select()` now works correctly, though it's
-  not implemented very efficiently. [bug=1520530]
-
-* Fixed a Python 3 ByteWarning when a URL was passed in as though it
-  were markup. Thanks to James Salter for a patch and
-  test. [bug=1533762]
-
-* We don't run the check for a filename passed in as markup if the
-  'filename' contains a less-than character; the less-than character
-  indicates it's most likely a very small document. [bug=1577864]
-
-= 4.4.1 (20150928) =
-
-* Fixed a bug that deranged the tree when part of it was
-  removed. Thanks to Eric Weiser for the patch and John Wiseman for a
-  test. [bug=1481520]
-
-* Fixed a parse bug with the html5lib tree-builder. Thanks to Roel
-  Kramer for the patch. [bug=1483781]
-
-* Improved the implementation of CSS selector grouping. Thanks to
-  Orangain for the patch. [bug=1484543]
-
-* Fixed the test_detect_utf8 test so that it works when chardet is
-  installed. [bug=1471359]
-
-* Corrected the output of Declaration objects. [bug=1477847]
-
-
-= 4.4.0 (20150703) =
-
-Especially important changes:
-
-* Added a warning when you instantiate a BeautifulSoup object without
-  explicitly naming a parser. [bug=1398866]
-
-* __repr__ now returns an ASCII bytestring in Python 2, and a Unicode
-  string in Python 3, instead of a UTF8-encoded bytestring in both
-  versions. In Python 3, __str__ now returns a Unicode string instead
-  of a bytestring. [bug=1420131]
-
-* The `text` argument to the find_* methods is now called `string`,
-  which is more accurate. `text` still works, but `string` is the
-  argument described in the documentation. `text` may eventually
-  change its meaning, but not for a very long time. [bug=1366856]
-
-* Changed the way soup objects work under copy.copy(). Copying a
-  NavigableString or a Tag will give you a new NavigableString that's
-  equal to the old one but not connected to the parse tree. Patch by
-  Martijn Peters. [bug=1307490]
-
-* Started using a standard MIT license. [bug=1294662]
-
-* Added a Chinese translation of the documentation by Delong .w.
-
-New features:
-
-* Introduced the select_one() method, which uses a CSS selector but
-  only returns the first match, instead of a list of
-  matches. [bug=1349367]
-
-* You can now create a Tag object without specifying a
-  TreeBuilder. Patch by Martijn Pieters. [bug=1307471]
-
-* You can now create a NavigableString or a subclass just by invoking
-  the constructor. [bug=1294315]
-
-* Added an `exclude_encodings` argument to UnicodeDammit and to the
-  Beautiful Soup constructor, which lets you prohibit the detection of
-  an encoding that you know is wrong. [bug=1469408]
-
-* The select() method now supports selector grouping. Patch by
-  Francisco Canas [bug=1191917]
-
-Bug fixes:
-
-* Fixed yet another problem that caused the html5lib tree builder to
-  create a disconnected parse tree. [bug=1237763]
-
-* Force object_was_parsed() to keep the tree intact even when an element
-  from later in the document is moved into place. [bug=1430633]
-
-* Fixed yet another bug that caused a disconnected tree when html5lib
-  copied an element from one part of the tree to another. [bug=1270611]
-
-* Fixed a bug where Element.extract() could create an infinite loop in
-  the remaining tree.
-
-* The select() method can now find tags whose names contain
-  dashes. Patch by Francisco Canas. [bug=1276211]
-
-* The select() method can now find tags with attributes whose names
-  contain dashes. Patch by Marek Kapolka. [bug=1304007]
-
-* Improved the lxml tree builder's handling of processing
-  instructions. [bug=1294645]
-
-* Restored the helpful syntax error that happens when you try to
-  import the Python 2 edition of Beautiful Soup under Python
-  3. [bug=1213387]
-
-* In Python 3.4 and above, set the new convert_charrefs argument to
-  the html.parser constructor to avoid a warning and future
-  failures. Patch by Stefano Revera. [bug=1375721]
-
-* The warning when you pass in a filename or URL as markup will now be
-  displayed correctly even if the filename or URL is a Unicode
-  string. [bug=1268888]
-
-* If the initial <html> tag contains a CDATA list attribute such as
-  'class', the html5lib tree builder will now turn its value into a
-  list, as it would with any other tag. [bug=1296481]
-
-* Fixed an import error in Python 3.5 caused by the removal of the
-  HTMLParseError class. [bug=1420063]
-
-* Improved docstring for encode_contents() and
-  decode_contents(). [bug=1441543]
-
-* Fixed a crash in Unicode, Dammit's encoding detector when the name
-  of the encoding itself contained invalid bytes. [bug=1360913]
-
-* Improved the exception raised when you call .unwrap() or
-  .replace_with() on an element that's not attached to a tree.
-
-* Raise a NotImplementedError whenever an unsupported CSS pseudoclass
-  is used in select(). Previously some cases did not result in a
-  NotImplementedError.
-
-* It's now possible to pickle a BeautifulSoup object no matter which
-  tree builder was used to create it. However, the only tree builder
-  that survives the pickling process is the HTMLParserTreeBuilder
-  ('html.parser'). If you unpickle a BeautifulSoup object created with
-  some other tree builder, soup.builder will be None. [bug=1231545]

-         `features`. You only need to use this if you've implemented a
-         custom TreeBuilder.
-
-        :param parse_only: A SoupStrainer. Only parts of the document
-         matching the SoupStrainer will be considered. This is useful
-         when parsing part of a document that would otherwise be too
-         large to fit into memory.
-
-        :param from_encoding: A string indicating the encoding of the
-         document to be parsed. Pass this in if Beautiful Soup is
-         guessing wrongly about the document's encoding.
-
-        :param exclude_encodings: A list of strings indicating
-         encodings known to be wrong. Pass this in if you don't know
-         the document's encoding but you know Beautiful Soup's guess is
-         wrong.
-
-        :param element_classes: A dictionary mapping BeautifulSoup
-         classes like Tag and NavigableString, to other classes you'd
-         like to be instantiated instead as the parse tree is
-         built. This is useful for subclassing Tag or NavigableString
-         to modify default behavior.
-
-        :param kwargs: For backwards compatibility purposes, the
-         constructor accepts certain keyword arguments used in
-         Beautiful Soup 3. None of these arguments do anything in
-         Beautiful Soup 4; they will result in a warning and then be
-         ignored.
-         
-         Apart from this, any keyword arguments passed into the
-         BeautifulSoup constructor are propagated to the TreeBuilder
-         constructor. This makes it possible to configure a
-         TreeBuilder by passing in arguments, not just by saying which
