Re: Different between 5.x and 6.x

[Filipe Silva]

Hi Bernhard,

Connector/J 5.1 series is the current recommended version to use.

You wouldn't want to use Connector/J 6.0 series at all since it bumped to 8.0 between 6.0.6 and 8.0.7. Although it doesn't look like, those two are consecutive (development) releases of the same product. This is so because MySQL server and connectors (as well as a few other satellite products) are aligned to the major version from now on.

So, the next major version I advise you to use is Connector/J 8.0.x. But I would recommend you to only use it in production environments after becoming GA - current version is Connector/J 8.0.9 and it is a release candidate.

Main differences between Connector/J 5.1 and 8.0 series are:
- Connector/J 8.0 requires Java 8 or above.
- Internal major refactoring.
- Support for X DevAPI (https://dev.mysql.com/doc/x-devapi-userguide/en/).
