Historical Note Support of ArrayBuffer values was restored in 3.0.0.

Historical Note This release introduced the boolean binaryKeys and arrayKeys properties on the constructor, indicating whether the environment supports binary and array keys respectively. These properties may become private.

Historical Note The vendored IndexedDBShim is still included, but likely to be removed.

Historical Note Though we upgraded browserify to 16.2.2, the effective version used in tests is 13.3.0 because we switched from beefy to airtap, which ships with its own browserify dependency.
