Hi, All. We know that there were some struggles to migrate from Apache ORC 1.5 to ORC 1.6 due to API compatibility.
Now, we are more careful at ORC 1.7, but I'm wondering if we have an official
policy for Apache ORC versioning.
If it's not clear, I'd like to suggest to follow `Semantic Versioning` in
Apache ORC project and to document it in Apache ORC website officially.
