• Check that the user provided a valid token when running buf registry login.
• Add buf mod open that opens a module's homepage in a browser.
• Add buf completion command to generate auto-completion scripts in commonly used shells.
• Add --disable-symlinks flag to the breaking, build, export, generate, lint, ls-files, push
  commands. By default, the CLI will follow symlinks except on Windows, and this disables following
  symlinks.
• Add --include-wkt flag to buf generate. When this flag is specified alongside
  --include-imports, this will result in the Well-Known Types
  being generated as well. Most language runtimes have the Well-Known Types included as part
  of the core library, making generating the Well-Known Types separately undesirable.
• Remove buf protoc. This was a pre-v1.0 demonstration to show that buf compilation
  produces equivalent results to mainline protoc, however buf is working on building
  a better Protobuf future that provides easier mechanics than our former protoc-based
  world. buf protoc itself added no benefit over mainline protoc beyond being considerably
  faster and allowing parallel compilation. If protoc is required, move back to mainline protoc
  until you can upgrade to buf. See #915 for more
  details.
• Context modifier no longer overrides an existing token on the context. This allows buf registry login
  to properly check the user provided token without the token being overriden by the CLI interceptor.
• Removed the buf config init command in favor of buf mod init.
• Removed the buf config ls-breaking-rules command in favor of buf mod ls-breaking-rules.
• Removed the buf config ls-lint-rules command in favor of buf mod ls-lint-rules.
• Removed the buf config migrate-v1beta1 command in favor of buf beta migrate-v1beta1.
• Add buf beta decode command to decode message with provided image source and message type.
• Disable --config flag for workspaces.
• Move default config version from v1beta1 to v1.
