v0.2.0

Added

• render <project.json> command for project-based multi-scene rendering.
• Project config support for scenes, outputs, reusable defaults, and
  project-level summary manifests.
• Scene actions and mid-capture timeline segments including pause,
  scroll, click, hover, press, type, and scroll-to.
• Multi-output rendering with per-output viewport, audio, subtitles,
  transitions, and encoder settings.
• Node library exports for project loading, render planning, and render
  execution.
• JSON Schema and sample project config for editor validation and onboarding.
• Scene-to-scene crossfade transitions.
• Subtitle support for both soft and burn-in modes with .srt, .vtt, and
  .webvtt inputs.
• finalVideo encoder controls for final mp4 and webm outputs.
• intermediateArtifact profiles for scene clip generation.

Changed

• Render orchestration now uses an explicit render-plan layer that separates
  scene capture from final composition.
• Render manifests now use schema version 2 and separate captureMetrics
  from artifactMetrics.
• Probe handling now records explicit status and warnings, and fails fast when
  precise clip timing is required by composition capabilities such as
  crossfade.

v0.1.9

Added

• TTY-aware progress bar during frame rendering; falls back to milestone percentages in non-TTY environments.
• --force flag to overwrite an existing output file.
• --version / -V flag to print the current version.
• --help / -h at both top-level and subcommand level.
• Graceful cancellation via SIGINT / SIGTERM with partial-output cleanup.
• Capture summary printed to stderr on completion (file size, duration, frame count, pages, manifest path).
• FFmpeg availability pre-check with platform-specific install instructions.
• Frame-count safety limit (36,000 frames) and FPS cap (120) to prevent runaway captures.
• --hide-selector input validation (rejects selectors containing { or }).
• URL credential sanitization — userinfo is stripped from all logs and manifests.

Changed

• Font loading now times out after 10 s instead of waiting indefinitely.
• Preflight page measurement stops after 20 iterations to avoid infinite loops on dynamically-loading pages.
• Browser session properly closes when context creation fails.
• FFmpeg encoder supports abort with SIGTERM → SIGKILL escalation.
• Manifest status field now includes a cancelled value.
• Error messages throughout the CLI include actionable hints and expected formats.
• Help text now shows default values, max constraints, and usage examples.
