Changelog

All notable changes to this project will be documented in this file.

[1.5.0] - 2026-03-29

Added

• wfe-rustlang: New crate with Rust toolchain step executors
  • Cargo steps: cargo-build, cargo-test, cargo-check, cargo-clippy, cargo-fmt, cargo-doc, cargo-publish
  • External tool steps with auto-install: cargo-audit, cargo-deny, cargo-nextest, cargo-llvm-cov
  • Rustup steps: rust-install, rustup-toolchain, rustup-component, rustup-target
  • cargo-doc-mdx: generates MDX documentation from rustdoc JSON output using the rustdoc-types crate
• wfe-yaml: rustlang feature flag enabling all cargo/rustup step types
• wfe-yaml: Schema fields for Rust steps (package, features, toolchain, profile, output_dir, etc.)
• wfe-containerd: Remote daemon support via WFE_IO_DIR environment variable
• wfe-containerd: Image chain ID resolution from content store for proper rootfs snapshots
• wfe-containerd: Docker-default Linux capabilities for root containers
• Lima wfe-test VM config (Alpine + containerd + BuildKit, TCP socat proxy)
• Containerd integration tests running Rust toolchain in containers

Fixed

• wfe-containerd: Empty rootfs — snapshot parent now resolved from image chain ID instead of empty string
• wfe-containerd: FIFO deadlock with remote daemons — replaced with regular file I/O
• wfe-containerd: sh: not found — use absolute /bin/sh path in OCI process spec
• wfe-containerd: setgroups: Operation not permitted — grant capabilities when running as UID 0

Changed

• Lima wfe-test VM uses Alpine apk packages instead of GitHub release binaries
• Container tests use TCP proxy (http://127.0.0.1:2500) instead of Unix socket forwarding
• CI pipeline (workflows.yaml) updated with wfe-rustlang in test, package, and publish steps

879 tests. 88.8% coverage on wfe-rustlang.

[1.4.0] - 2026-03-26

Added

• Type-safe when: conditions on workflow steps with compile-time validation
• Full boolean combinator set: all (AND), any (OR), none (NOR), one_of (XOR), not (NOT)
• Task file includes with cycle detection
• Self-hosting CI pipeline (workflows.yaml) demonstrating all features
• readFile() op for deno runtime
• Auto-typed ##wfe[output] annotations (bool, number conversion)
• Multi-workflow YAML files, SubWorkflow step type, typed input/output schemas
• HostContext for programmatic child workflow invocation
• BuildKit image builder and containerd container runner as standalone crates
• gRPC clients generated from official upstream proto files (tonic 0.14)

Fixed

• Pipeline coverage step produces valid JSON, deno reads it with readFile()
• Host context field added to container executor test contexts
• .outputs. paths resolved flat for child workflows
• Pointer status conversion for Skipped in postgres provider

629 tests. 87.7% coverage.
