Breaking changes

  • Require Elixir 1.18+ and Erlang/OTP 28+.
  • Use PhoenixAssetPipeline.HTML.Engine for HEEx templates.
  • Add :phoenix_asset_pipeline_prepare before Elixir and :phoenix_asset_pipeline after :app.
  • Replace the previous asset tasks and storage with the manifest pipeline.
  • Remove phoenix_asset_pipeline.assets.build, phoenix_asset_pipeline.assets.deploy, and packaged image/SVG scripts.
  • Move development rebuilds from endpoint watchers to PhoenixAssetPipeline.Watcher.
  • Default :manifest_mode to :cached; production builds must select :precompiled and provide an exact :bun_version plus assets/bun.lock.

Highlights

  • Build JS, Tailwind CSS, SVG sprites, optimized images, static files, and the manifest in one pipeline.
  • Namespace internal sprite IDs by default and support cache-aware root metadata from metadata_file.
  • Minify module-scope classes before Elixir compilation and reserve identical mappings during CSS rewriting.
  • Resolve function and HEEx class expressions from the current manifest at runtime.
  • Rewrite CSS selectors and Tailwind custom properties in native passes without Elixir byte scanning.
  • Deduplicate content, cache build outputs, and compress production assets with four bounded workers.
  • Serve sparse Brotli, gzip, deflate, and Zstandard representations with range and conditional request support.
  • Store dynamic manifests in indexed ETS generations and generate precompiled production manifests.
  • Provide manifest-backed HTML helpers, components, CSP helpers, early hints, LiveView integration, and static plugs.
