-**Historical Note** As a result of removing `IDBWrapper`, only modern browsers with a non-prefixed `window.indexedDB` are supported in this release. IE10 and Firefox 52 are known to be broken. The current test matrix of `level-js` includes the latest versions of Chrome, Firefox, Safari, Edge and IE.

 **Historical Note** Though `level-js` now passes the full `abstract-leveldown` test suite, fulfulling the snapshot guarantee (reads not being affected by simultaneous writes) means a loss of backpressure as iterators have to keep reading from their IndexedDB cursors. Memory consumption might increase if an iterator is not consumed fast enough. A future release will have an option to favor backpressure over snapshot guarantees.
