Only test coverage. We didn't run direct testing to 0.14.2 - we also deliberately made the decision not to remove some older code that would have broken 0.14 upgrades until the next major release.
It all depends on your risk tolerance - we didn't make any file format changes to bitcask so your data should be safe. If you wanted to try it, I would take a backup of the ring directory in case you had to downgrade the node again for any reason. On the newly upgraded node you could run riak_core_capability:all(). on the riak console, that would double-check that the settings matched the required rolling upgrade settings, and make sure you do a diff of your app.config/vm.args against the new package to check there aren't any settings missing.
