Prompt Optimizer v2.8.0

Summary

• Expanded text-to-image evaluation with multimodal review, result inspection, and original-prompt analysis.
• Smoothed the reference-image workflow from dialog design and prompt migration to safer preview and download actions.
• Strengthened the platform foundation with Cloudflare-backed providers and a more reliable desktop packaging setup.

Highlights

• Expanded the text-to-image workflow with multimodal evaluation, result review, and original-prompt analysis.
• Made reference-image workflows much smoother, from dialog design and prompt migration to safer preview and download actions.
• Strengthened the model and packaging foundations with new Cloudflare-backed providers and a more reliable desktop release setup.

Product Updates

Desktop

• Upgraded the desktop packaging toolchain to electron-builder 26.8.2.
• Removed repository-level Electron mirror defaults that could interfere with CI release builds.

Web

• Redesigned the text-to-image reference dialog so style migration and reference replication feel more direct.
• Added the new text-to-image evaluation workflow to the UI, including analysis and evaluation entry points around image generation.
• Improved preview downloads, temporary-variable state persistence, and several smaller interaction details in headers, popovers, and navigation guards.

Core/Infra

• Added Cloudflare-backed text and image providers, plus multimodal support for text-to-image evaluation.
• Rebuilt the reference-prompt pipeline to better support composition, migration, compare evaluation, and result evaluation flows.
• Normalized legacy template identifiers and wrapped evidence payloads in structured JSON blocks so evaluation behavior stays more consistent.

Fixes

• Fixed the preview download hit area and normalized URL-based image results.
• Hardened safe image preview downloads and stabilized the Cloudflare-backed reference-image flow.
• Backfilled missing built-in model API keys and aligned evaluation fixtures with the updated image workflow.

Breaking Changes / Upgrade Notes

• None. Existing saved data and current workspaces should continue to work without migration steps.

Developer Notes

• This release reshapes a large part of the image prompt pipeline. If you maintain custom templates or evaluation prompts, expect more structured evidence blocks and more explicit stage-aware evaluation paths.
• The commit range from v2.7.0 to v2.8.0 also includes repo cleanup, dependency alignment, and documentation reshaping work, but the user-facing center of gravity is clearly the image evaluation stack.
