v0.7.0

Zygote v0.7.0

Diff since v0.6.75

Breaking changes:

• Now Zygote doesn't always unthunk ChainRulesCore's thunks, saving computation and memory in some situations. This may break some ChainRules' rules that are not correctly written, but no changes are usually required. (#966)

Merged pull requests:

• Utilize ChainRulesCore thunks (#966) (@oschulz)
