Regarding future versions, according to the announcement post by Senior Research Developer at Oracle Labs Thomas Wuerthinger, v20 will release next year in 2020. With this schedule, a new major version arrives yearly, with updates in between handling bug issues and security enhancements.

He writes:

These releases are going to be built from master and include the latest bits. We intend to make the update process smooth and only gradually introduce new features. This means first having major changes behind an experimental flag and only later enabling that flag by default. This allows us to keep a high velocity for the project while allowing users to adjust well in advance.
