#### `.batch(array)` enforces objects
|
|
|
|
This major release contains an upgrade to `abstract-leveldown` with a [breaking change](https://github.com/Level/abstract-leveldown/commit/a2621ad70571f6ade9d2be42632ece042e068805) 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.
|
|
|
|
## v3
|
|
|
|
Dropped support for node 0.12. No other breaking changes.
