[RELEASE] OSS driver 4.1.0 and DSE driver 2.1.0

[Olivier Michallat]

We've just released the latest version of our drivers.

The main feature is the new object mapper (JAVA-2078). Like in previous versions, it relies on annotations to configure mapped entities and queries. However, there are a few notable differences:

• it uses compile-time annotation processing instead of runtime reflection;
• the "mapper" and "accessor" concepts have been unified into a single "DAO" component, that handles both pre-defined CRUD patterns, and user-provided queries.

For a complete tour, refer to the driver manual:

• on docs.datastax.com (might take a little while to sync, if you get a 404 use the next link)
• direct GitHub link
