1.3.1

1.3.1

• FIX: Fix issue with undefined namespaces.

1.3.0

1.3.0

• NEW: Add support for :scope.
• NEW: :user-invalid, :playing, :paused, and :local-link will not cause a failure, but all will match nothing as their use cases are not possible in an environment outside a web browser.
• FIX: Fix [attr~=value] handling of whitespace. According to the spec, if the value contains whitespace, or is an empty string, it should not match anything.
• FIX: Precompile internal patterns for pseudo-classes to prevent having to parse them again.

1.2.1

1.2.1

• FIX: More descriptive exceptions. Exceptions will also now mention position in the pattern that is problematic.
• FIX: filter ignores NavigableString objects in normal iterables and Tag iterables. Basically, it filters all Beautiful Soup document parts regardless of iterable type where as it used to only filter out a NavigableString in a Tag object. This is viewed as fixing an inconsistency.
• FIX: DEBUG flag has been added to help with debugging CSS selector parsing. This is mainly for development.
• FIX: If forced to search for language in meta tag, and no language is found, cache that there is no language in the meta tag to prevent searching again during the current select.
• FIX: If a non BeautifulSoup/Tag object is given to the API to compare against, raise a TypeError.

1.2.0

1.2.0

• NEW: Add Python 2.7 support.
• NEW: Remove old pre 1.0 deprecations.

1.1.0

1.1.0

• NEW: Adds support for [attr!=value] which is equivalent to :not([attr=value]).
• NEW: Add support for :active, :focus, :hover, :visited, :target, :focus-within, :focus-visible, :target-within, :current()/:current, :past, and :future, but they will never match as these states don't exist in the Soup Sieve environment.
• NEW: Add support for :checked, :enabled, :disabled, :required, :optional, :default, and :placeholder-shown which will only match in HTML documents as these concepts are not defined in XML.
• NEW: Add support for :link and :any-link, both of which will target all <a>, <area>, and <link> elements with an href attribute as all links will be treated as unvisited in Soup Sieve.
• NEW: Add support for :lang() (CSS4) which works in XML and HTML.
• NEW: Users must install Beautiful Soup themselves. This requirement is removed in the hopes that Beautiful Soup may use this in the future.
• FIX: Attributes in the form prefix:attr can be matched with the form [prefix\:attr] without specifying a namespaces if desired.
• FIX: Fix exception when [type] is used (with no value).

1.0.2

1.0.2

• FIX: Use proper CSS identifier patterns for tag names, classes, ids, etc. Things like #3 or #-3 should not match and should require #\33 or #-\33.
• FIX: Do not raise NotImplementedError for supported pseudo classes/elements with bad syntax, instead raise SyntaxError.

1.0.1

1.0.1

• FIX: When giving a tag to select, it should only return the children of that tag, never the tag itself.
• FIX: For informational purposes, raise a NotImplementedError when an unsupported pseudo class is used.

1.0.0

1.0.0

• NEW: Official 1.0.0 release.

1.0.0b2

1.0.0b2

• FIX: CSS selectors should be evaluated with CSS whitespace rules.
• FIX: Processing instructions, CDATA, and declarations should all be ignored in :contains and child considerations for :empty.
• FIX: In Beautiful Soup, the document itself is the first tag. Do not match the "document" tag by returning false for any tag that doesn't have a parent.

1.0.0b1

1.0.0b1

• NEW: Add support for non-standard :contains() selector.
• FIX: Compare pseudo class names case insensitively when matching unexpected cases.
• FIX: Don't allow attribute case flags when no attribute value is defined.
