What's Changed

Major changes to how the command line generation tool autocxx_gen works. If you're just using cargo you probably don't need to worry about this, but if you're using other build systems you'll almost certainly need to make changes.

• Remove make_unique. by @adetaylor in https://github.com/google/autocxx/pull/1040

This release also upgrades some of our dependencies:

• Upgrade to clap 3 by @gabriel-viviani (thanks!) in https://github.com/google/autocxx/pull/1037
