v4.5.0

New Shims

• parseFloat('-0') should return -0 in Opera 12 (#371)
• Provide and replace Date UTC methods (#360)

Robustness

• cache Date getUTC* methods so that Date#toISOString doesn’t observably look them up on the receiver
• use a cached and shimmed String#trim

Tests

• up to node v5.5
• add parallelshell and use it in a few tasks

Refactors

• rename cached methods to avoid linter warnings

Dev Deps

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

Docs

• Update license year to 2016 (#374)
