I've just released Sup 1.1. It includes various bug fixes around character encodings, plus Ruby 3.0 and 3.1 support. The new release is available from Rubygems and Github. == 1.1 / 2022-05-23 * #588, #577: Sup is now compatible with and tested on Ruby 3.0 and Ruby 3.1. (Dan Callaghan) * When the Sup gem installs xapian-ruby, it will install to the user gem directory if the system gem directory is not writable. (Iain Parris) * #571: To and From addresses of enclosed messages are now displayed normally, instead of as Redwood::Person objects. (Iain Parris) * #570: Fixed wording when displaying enclosed messages without Date header. (Iain Parris) * #205, #602: UTF-8 header values are now accepted and handled correctly, as per RFC6532. (Dan Callaghan) * #585: Text/plain attachments with invalid charset are now displayed as US-ASCII (with high bytes replaced) instead of crashing. (Dan Callaghan) * #424: Spaces are now accepted in RFC2047-encoded header words, even though the RFC forbids them. (Dan Callaghan) * Invalid RFC2047-encoded header words are now displayed in their raw form, rather than trying to forcibly transcode them to UTF-8, as per the RFC's recommendation. (Dan Callaghan) * Sup now decodes UTF-7 correctly instead of crashing. (Dan Callaghan) -- Dan Callaghan
