Changelog

Sourced from werkzeug's changelog.

Version 3.1.8

Released 2026-04-02

• Request.host and get_host return the empty string if the header is missing or has invalid characters. :issue:3142

Version 3.1.7

Released 2026-03-23

• parse_list_header preserves partially quoted items, discards empty items, and returns empty for unclosed quoted values. :pr:3128
• WWWAuthenticate.to_header does not produce a trailing space when there are no parameters. :issue:3127
• Transfer-Encoding is parsed as a set. :pr:3134
• Request.host, get_host, and host_is_trusted validate the characters of the value. An empty value is no longer allowed. A Unix socket server address is ignored. The trusted_list argument to host_is_trusted is optional. :pr:3113
• Fix multipart form parser handling of newline at boundary. :issue:3088
• Response.make_conditional sets the Accept-Ranges header even if it is not a satisfiable range request. :issue:3108
• merge_slashes merges any number of consecutive slashes. :issue:3121

Version 3.1.6

Released 2026-02-19

• safe_join on Windows does not allow special devices names in multi-segment paths. :ghsa:29vq-49wr-vm6x
• Response.make_conditional sets the Accept-Ranges header even if it is not a satisfiable range request. :issue:3108

Version 3.1.5

Released 2026-01-08

• safe_join on Windows does not allow more special device names, regardless of extension or surrounding spaces. :ghsa:87hc-h4r5-73f7
• The multipart form parser handles a \r\n sequence at a chunk boundary. This fixes the previous attempt, which caused incorrect content lengths. :issue:3065 :issue:3077
