Subject: [PATCH] test against supported Rails 4.2
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Rails 4.2 env entry was removed from Travis CI as a simple workaround for failing tests in 593de1b86b57f9070c5904c5491bcfc32f1df089. As Rails 4.2 is still supported (see the latest merge commit – https://github.com/caxlsx/axlsx_rails/commit/237cbbde1a3e763ee208b08424c03d4f00e93cd6) it should be tested against in Travis CI as well.

See https://docs.travis-ci.com/user/languages/ruby/#bundler-20.
