 # Changelog
 
+## Unreleased
+
+### Fixed
+- Verdicts with invalid plotline IDs are now skipped instead of applied

+- CLI callback inherits PipelineCallback to prevent AttributeError on batch mode
+
+### Added
+- CLI progress output: prints status after each pipeline pass
+- `write-synopses` creates folder named after show (`mad-men/`) instead of generic `synopses/`

+- Per-episode theme in output JSON
+
+### Changed
+- Plotline count limits in prompts: max 5 (non-ensemble), 5–6 (ensemble)

+- Pass 2 CLI default changed from parallel to batch
+
