Mime-types 2.1 Released

mime-types version 2.1 has been released!

The mime-types library provides a library and registry for information
about
MIME content type definitions. It can be used to determine defined
filename
extensions for MIME types, or to use filename extensions to look up the
likely
MIME type definitions.

MIME content types are used in MIME-compliant communications, as in
e-mail or
HTTP traffic, to indicate the type of content which is transmitted. The
mime-types library provides the ability for detailed information about
MIME
entities (provided as an enumerable collection of MIME::Type objects) to
be
determined and used programmatically. There are many types defined by
RFCs and
vendors, so the list is long but by definition incomplete; don’t
hesitate to to
add additional type definitions (see Contributing.rdoc). The primary
sources
for MIME type definitions found in mime-types is the IANA collection of
registrations (see below for the link), RFCs, and W3C recommendations.

This is release 2.1, mostly changing how the MIME type registry is
updated from
the IANA registry (the format of which was incompatibly changed shortly
before
this release) and taking advantage of the extra data available from IANA
registry in the form of MIME::Type#xrefs. In addition, the {LTSW
list}[http://www.ltsw.se/knbase/internet/mime.htp] has been dropped as a
supported list.

As a reminder, mime-types 2.x is no longer compatible with Ruby 1.8 and
mime-types 1.x is only being maintained for security issues. No new MIME
types
or features will be added.

mime-types (previously called MIME::Types for Ruby) was originally based
on
MIME::Types for Perl by Mark Overmeer, copyright 2001 - 2009. It is
built to
conform to the MIME types of RFCs 2045 and 2231. It tracks the {IANA
Media
Types
registry}[https://www.iana.org/assignments/media-types/media-types.xhtml]
with some types added by the users of mime-types.

Changes:

2.1 / 2014-01-25

  • API Changes (MIME::Type):
    • Added MIME::Type#xrefs and MIME::Type#xref_urls that have better
      handling
      of types of reference information. MIME::Type#references= has been
      deprecated. In a future release, both MIME::Type#references will be
      turned
      into a short-hand view on MIME::Type#xrefs, MIME::Type#urls will be
      an
      alias for MIME::Type#xref_urls, and MIME::Type#references= will be
      removed.
  • New or Updated MIME Types:
    • This information is now tracked in History-Types.rdoc.
  • MIME Type Development Tools
    • The IANA registry format changed, breaking the IANA registry tool
      previously used. Rewrote IANADownloader and IANADownloader::Parser
      as
      IANARegistryParser using the XML form.
    • The LTSW list has been dropped as it has not been updated since
  • The default Apache MIME types configuration list is now used to
    enrich MIME
    type data with additional extension information.
