Conductor 0.1.42

[0.1.42] - 2026-10-06

Added

• Template filter fromjson: added a fromjson Jinja filter that parses
  JSON text into native values, the inverse of the existing json filter. MCP
  step results (for example output.content[0].text) can now be parsed inside
  templates to build arguments for downstream steps. (#579)
• Docker execution backend for containerized script steps: executes type: script
  workflow steps inside short-lived containers against a run-scoped shared named
  volume (conductor-ws-<run_id>). Execution environment documents declare docker
  profiles with configurable container image, target platform, network mode,
  container user, init process, read-only root filesystem, Linux capability drops,
  privilege escalation blocks, memory-backed /tmp tmpfs mounts, and CPU, memory,
  and PID resource constraints. Conductor automatically collects the workflow's
  content-addressed run bundle closure and stages it into the shared volume before
  execution, isolating script steps while preserving shared workspace state across
  steps within the run. (#584)
• Opt-in live-validation harness and operator runbook for Claude subscription
  billing mode. (#586)

Changed

• Dependabot-authored pull requests no longer require changelog fragments:
  the check recognizes Dependabot from the pull request author while continuing
  to reject direct CHANGELOG.md edits and validate any fragment changes. (#578)
