  Releasing 0.7.3
  Hi @encode/httpx-maintainers!
  
  It’s been 21 days since 0.7.2 was released, and we’ve got [a bunch of features](https://github.com/encode/httpx/compare/0.7.2...HEAD) ready for 0.7.3 already, eg:
  
  - Digest auth
  - SSLKEYLOGFILE
  - Response.elapsed
  - A host of bug fixes
  
  So regardless of what gets merged until then I think it’s time to release the next version. :)
  
  As suggested by @sethmlarson I-cant-remember-where I’d like to take on this release. I’ll probably take the opportunity to document the release process as well - #313. 👍
  
  Probably will do tonight.
