v5.0.3

Happy Monday, y'all! We've got another npm release for you with the fruits of our ongoing bugsquashing efforts. You can expect at least one more this week, but probably more -- and as we announced last week, we'll be merging fixes more rapidly into the npmc canary so you can get everything as soon as possible!

Hope y'all are enjoying npm5 in the meantime, and don't hesitate to file issues for anything you find! The goal is to get this release rock-solid as soon as we can. 💚

• 6e12a5cc0 Bump several dependencies to get improvements and bugfixes:
  • cacache: content files (the tarballs) are now read-only.
  • pacote: fix failing clones with bad heads, send extra TLS-related opts to proxy, enable global auth configurations and _auth-based auth.
  • ssri: stop crashing with can't call method find of undefined when running into a weird opts.integrity/opts.algorithms conflict during verification.
