Release Notes - v0.7.3

Release Window

2025-08-29 to 2025-09-15

Overview

This minor release series covers v0.7.3.0 through v0.7.3.9. The focus was stabilizing prompt construction, image-generation retries, and Modular Mechanics state handling while also introducing the first ETCH MCP server tooling, version bump support, and a cleaner story-node generation pipeline.

Highlights

• Added profanity-filter retry handling for image-generation content-policy failures.
• Sanitized and validated story node IDs across create and edit flows.
• Refactored image prompt fields and conditional layer prompt visibility.
• Introduced the ETCH MCP server, version tooling, and early MCP debug/logging infrastructure.
• Cleaned up story-node generation flow and added markdown and HTML support for story text.

Patch Milestones

v0.7.3.0 to v0.7.3.1

• Added logging for content-policy failures and a second-pass prompt retry path.
• Fixed token replacement order so combined prompts resolve placeholders correctly.
• Prevented invalid option output when no valid choice is returned from generation.
• Removed deprecated prompt-generation code and consolidated image prompt handling.
• Refined prompt field behavior and conditional layer visibility in the authoring UI.

v0.7.3.2 to v0.7.3.6

• Added the first ETCH MCP server implementation and configuration.
• Added parameter definitions, input-schema fixes, and register-tool fixes for MCP operations.
• Added version bump tooling and follow-up fixes so version operations became part of the MCP workflow.
• Improved MCP debug logging, recent-log output, and tool-call visibility during development.

v0.7.3.7 to v0.7.3.9

• Landed backend test fixes and cleanup work after the MCP rollout.
• Refactored story-node generation for a cleaner and more maintainable flow.
• Added $ prefix support in variable handling.
• Added markdown and HTML support for story text rendering.
• Tightened node ID validation in both UI and backend processing.

Other Notable Improvements

• Improved Modular Mechanics cache behavior and variable refresh when navigating back to the initial node.
• Updated cache refresh behavior after node saves so edits appear more reliably without stale state.
• Added theme metadata validation cleanup alongside the prompt refactor work.
• Improved CI and deployment behavior by moving modules into the backend and fixing build and unit-test execution.

Migration Notes

• Node IDs are normalized more aggressively and invalid characters are rejected or sanitized before save.
• Story text can now include markdown and HTML, so downstream rendering paths should assume richer formatted content.
• Version bumping is now part of the MCP tooling flow rather than a manual-only process.
