v4.3.0

New Shims (shim)

• Array#push: in IE <= 7, Array#push was not generic (#336)
• Array#push in Opera 10.6 has a super weird bug when pushing undefined
• Array#join: In IE <= 7, passing undefined didn't use the default separator (#333)
• Error#toString: prints out the proper message in IE 7 and below (#334)
• Number#toPrecision: IE 7 and below incorrectly throw when an explicit undefined precision is passed (#340)

Fixes (shim)

• String#lastIndexOf: ensure the correct length in IE 8
• ensure parseInt accepts negative and plus-prefixed hex values (#332)

Robustness

• Use a bound Array#push instead of relying on Function#call

Dev Deps

• update eslint, @ljharb/eslint-config, jscs

Tests

• Add some conditionals to avoid impossible-to-fix test failures in IE 6-8, due to it being unable to distinguish between undefined and an absent index (#114)
• Fix false negatives in IE 6-8 with jasmine comparing arrays to arraylikes (#114)
• add additional Array#shift tests (#337)
• Add additional Array#splice tests (#339)
• Add Array#pop tests, just in case (#338)
• include global tests in HTML test files
• Make sure the HTML tests run with the right charset
• ensure node v0.8 tests stay passing.
• Prevent nondeterminism in the tests - this sometime produced values that are one ms off
• test on node v5.0
• fix npm upgrades for older nodes
