v0.8.18

earthbuild v0.8.18

Full Changelog: v0.8.17...v0.8.18

This release completes most of the earthly → earth rename, adds OpenTelemetry
tracing, and removes the Earthly Cloud API. It also folds in ~250 dependency
bumps.

Breaking changes

• CLI binary renamed earthly → earth. CI configs, scripts, and PATH
  references that invoke earthly need to switch to earth.
  (#337,
  #346,
  #502,
  #691)
• EARTHLY_* env vars and built-in ARGs are deprecated in favor of
  EARTH_* equivalents. Usage now logs a warning; removal is planned for
  v0.9.0. See the migration guide.
  (#631,
  #710)
• Earthly Cloud API removed. Cloud-backed features (remote cache/satellites
  via the old Cloud API) are gone. (#324)
• Exec-form RUN no longer shell-wrapped. RUN ["cmd", "arg"] now execs
  directly instead of being wrapped in a shell — matches Dockerfile semantics,
  but changes behavior for anyone relying on shell expansion in exec-form RUN.
  (#242)
• Line continuations inside quoted strings are now stripped during parsing
  — a parser behavior change for Earthfiles with backslash-newlines inside
  quotes. (#694)
• Internal build target names changed to earthbuild-*, and CI-internal
  workflow inputs renamed to *_EARTH_* — only affects forks/contributors
  building from source. (#647,
  #645)

New functionality

• OpenTelemetry tracing, with a Grafana backend wired up for GitHub Actions.
  (#322,
  #455)
• Content-hash based caching plus new EARTH_GIT_* built-in args.
  (#341)
• Better error diagnostics on build failures. (#568)
• Earthfile lookup now walks up parent directories, so earth can be run
  from a subdirectory of a project. (#638)
• CLI now prints which buildkit it's using when it's non-standard, and
  correctly tags the buildkitd binary the CLI points at.
  (#390,
  #456)
• Go build flags support. (#320)
• New Ubuntu 26.04 dind image (Ubuntu 23.04 dropped).
  (#509)
• Manual kick-off for staging releases. (#436)
• New logo, dark/light-mode adaptive. (#450)
• Soft warning on PROJECT and --auto-skip usage to gather deprecation
  feedback. (#709)
