Changelog

1.4.3 (30-Oct-2017)

• Change parsing of qualified lists to retain the initial ordering whenever possible. The algorithm prefers explicit highest quality (1.0) preferences over inferred highest quality preferences. It also retains the initial ordering in the presence of multiple highest quality matches. This affects headers.parse_accept_charset(), headers.parse_accept_encoding(), and headers.parse_accept_language().

1.4.2 (04-Jul-2017)

• Add formatting of HTTP Link header using str(header).

1.4.1 (03-Apr-2017)

• Add some documentation about exceptions raised during header parsing.

1.4.0 (18-Oct-2016)

• Fixed parsing of lists like max-age=5, x-foo="prune". The previous versions incorrectly produced ['max-age=5', 'x-foo="prune'].
• Added headers.parse_accept_encoding() which parses HTTP Accept-Encoding header values into a list.
• Added headers.parse_accept_language() which parses HTTP Accept-Language header values into a list.

1.3.0 (11-Aug-2016)

• Added headers.parse_cache_control() which parses HTTP Cache-Control header values into a dictionary.
• Renamed headers.parse_http_accept_header() to headers.parse_accept(), adding a wrapper function that raises a deprecation function when invoking headers.parse_http_accept_header().
• Renamed headers.parse_link_header() to headers.parse_link(), adding a wrapper function that raises a deprecation function when invoking headers.parse_link_header().
• Renamed headers.parse_list_header() to headers.parse_list(), adding a wrapper function that raises a deprecation function when invoking headers.parse_list_header().

1.2.2 (27-May-2015)

• Added headers.parse_list_header() which parses generic comma- separated list headers with support for quoted parts.
• Added headers.parse_accept_charset() which parses an HTTP Accept-Charset header into a sorted list.

1.2.1 (25-May-2015)

• algorithms.select_content_type() claims to work with datastructures.ContentType` values but it was requiring the augmented ones returned from algorithms.parse_http_accept_header(). IOW, the algorithm required that the quality attribute exist. RFC 7231#section-5.3.1 states that missing quality values are treated as 1.0.

1.2.0 (19-Apr-2015)

• Added support for RFC 5988 Link headers. This consists of headers.parse_link_header() and datastructures.LinkHeader

1.1.1 (10-Feb-2015)

• Removed setupext module since it was causing problems with source distributions.

1.1.0 (26-Oct-2014)

• Added algorithms.rewrite_url()

1.0.0 (21-Sep-2014)

• Initial implementation containing the following functionality: - algorithms.select_content_type() - datastructures.ContentType - errors.NoMatch - errors.RootException - headers.parse_content_type() - headers.parse_http_accept_header()
