Dropped support for node 0.12, 4, 5 and 7.
This is an upgrade to leveldown-hyper@~2.0.0 which depends on abstract-leveldown@~5.0.0 which in turn contains breaking changes to .batch(). Though this is negated by levelup, we decided to release a new major version in the event of dependents reaching down into db.db.
The parts that make up level-hyper have been refactored to increase modularity. This is an upgrade to level-packager@~4.0.0, which in turn upgraded to levelup@^3.0.0. The responsibility of encoding keys and values moved from levelup to encoding-down, which comes bundled with level-packager.
Being a convenience package, level-hyper glues the parts back together to form a drop-in replacement for the users of levelup@1, while staying fully compatible with level-hyper@1. One thing we do get for free, is native Promise support.
const db = level('db')
await db.put('foo', 'bar')
console.log(await db.get('foo'))This does not affect the existing callback API, functionality-wise or performance-wise.
