Deno 1.0.5 Released (and 1.04, and 1.0.3) — Things move so fast in the world of Deno that we’ve had three releases since the last issue alone. We’ll wrap up some of the new features into this one post, though:

  • std/hash now supports SHA512 and HMAC-SHA512.
  • std/encoding can now encode Base64 (by wrapping btoa and atob)
  • The REPL now executes code in strict mode.
  • std/http supports 101, 103 (Early Hints) and 425 (Too Early) codes.
  • Lots of fixes, as you'd expect.
  • And, of course, lots more.
To upgrade: deno upgrade --version 1.0.5

Here's the 1.0.4 notes and 1.0.3 notes if you want to trawl through.
