v4.5.10

Fixes

• Safari 11 throws on .sort({}), but not on .sort(null)
• ensure the shimmed parseInt throws with Symbols (#450)
• skip over localStorage, which can’t be accessed on file://
• Accessing window.top.{constructor|prototype} throws error in iOS (#445)
• avoid width and height on window, to prevent reflow (ljharb/object-keys#31)
• ensure minified literal of 1000000000000000128 stays as that literal (#441)

Robustness

• always prefer String(x) over x.toString()

Tests

• up to node v9.3, v8.9, v7.10, v6.12, v5.12, v4.8; improve test matrix; use nvm install-latest-npm; comment out OS X builds; pin included builds to LTS
• parseInt: add another test for NaN parsing (#433)

Dev Deps

• uglify-js: add --support-ie8 and peg to v2.7.x since it doesn’t follow semver
• [Dev Deps] update eslint, @ljharb/eslint-config, jscs, uglify-js, semver; remove concurrently (#421)
