Hi,

The ruby-gettext project has been released gettext 3.0.0.

Web: http://ruby-gettext.github.io/
Install: gem install gettext

Gettext gem is the localization(L10N) library and tools
which is modeled after GNU gettext package.

Gettext gem includes command line tools to manager .po and
.mo. They are implemented by pure Ruby. GNU gettext also
provides these tools but they are implemented by C. Ruby
users can install these tools easily rather than GNU
gettext.


Gettext 3.0.0 removed many deprecated APIs and improves
internal APIs. We want to keep backward compatibility as
much as possible but some existing codes may be broken by
gettext gem API change. If your code breaks by gettext gem
3.0.0, please report your problem to GitHub Issues. (*) We
will fix the problem and release a new version.
