This document describes breaking changes and how to upgrade. For a complete list of changes including minor and patch releases, please refer to the changelog.
Dropped support for node 0.12, 4, 5, and 7.
If you're using node v10 you'll need at least leveldown-hyper@2.0.0 to successfully compile.
This major release contains an upgrade to abstract-leveldown with a breaking change for the array version of .batch(). This change ensures all elements in the batch array are objects.
If you previously passed arrays to .batch() that contained undefined or null, they would be silently ignored. Now this will produce an error.
