- updated to version 2.4.3
* Bugs:
* Restored Ruby 1.9.2 support by using +private_constant+ conditionally.
Fixes {#77}[https://github.com/halostatue/mime-types/issues/77] found by
Kris Leech (@krisleech). The conditional use of +private_constant+ here
will be removed for mime-types 3.0, when Ruby 1.9.2 support will be
unconditionally removed.

== 2.4.2 / 2014-10-15

* Bugs:
* Aaron Patterson (@tenderlove) found a loading bug and provided a fix that
nearly doubled registry load performance
({#74}[https://github.com/halostatue/mime-types/pull/74]).
* Godfrey Chan (@chancancode) provided a prophylactic security fix to use
JSON.parse instead of JSON.load in
{#75}[https://github.com/halostatue/mime-types/pull/75]. This provides a
20% improvement over the already improved result, resulting in a total 55%
performance boost.
