v0.2.0

✨ Feature

• Added an announcements system: admins can create, edit, pin, enable, disable, and schedule Markdown announcements; users can view, sort, close, or dismiss them for the day.
• Added redemption codes for balance credits and subscription time, with admin bulk creation, copy, export, enable, disable, delete, availability, remaining-count, and expiration management.
• Added subscription entitlement queues so users can see current and upcoming benefits; renewals extend time, while upgrades take effect immediately and preserve later benefits.
• Added conversation JSON export with conversation metadata, messages, runs, and compatibility information.
• Added message editing: editing user messages creates a new branch, and assistant replies can be revised with an “Edited” marker.
• Added image editing workflows based on uploaded images, including using generated images as follow-up edit inputs.
• Added streaming image generation and richer image generation previews, result display, and follow-up actions.
• Added drag-and-drop file upload, bulk file deletion, and a storage quota panel with unlimited quota display.
• Added chat preferences for font size, automatic title generation, and default file deletion when deleting conversations.
• Added an HTML visual prompt toggle to guide complex replies toward safe inline HTML layouts.
• Added visual model capability configuration for default options, option controls, image streaming, and official native tools.
• Added an official native tool catalog and tool pricing configuration for OpenAI, Google, Anthropic, xAI, and related providers.
• Added model access scopes and upstream source binding, allowing models to be public or internal-only and manually bound to existing upstream models.
• Added itemized upstream API key management with masked display, key append, deletion marking, and save-time application.

⚡ Optimization

• Improved version detection: the backend version endpoint now returns a buildID, and the frontend prompts users to refresh after a new deployment is detected.
• Improved subscription UX with clearer subscribe, renew, upgrade, unavailable, and payment-impact states.
• Improved payment configuration and order handling, including USD-to-CNY guidance and payment currency resolution.
• Improved model option passthrough with better protocol normalization, Google image parameters, native tool payload merging, and filter status hints.
• Improved the chat model options panel with side-by-side JSON and visual editing, option descriptions, filter states, and default restoration.
• Improved admin model management with clearer capability JSON guidance, parameter previews, source binding, and bulk status actions.
• Improved admin tool management by organizing MCP tools and official native-tool related controls under a clearer tools area.
• Improved rate limiting with a global toggle, public endpoint tiers, authentication protection, and standard rate-limit response headers.
• Improved static asset caching to reduce repeated requests for LobeHub vendor icons, export data, and logo carousel images.
• Improved generation reliability by marking pending messages when generation is canceled, making interrupted or refreshed sessions more accurate.
• Improved conversation branch selection and recent-list loading to reduce display mismatches from switching, pagination, and request races.
• Improved Markdown, KaTeX, and safe HTML rendering for more stable formula styling and inline visual layouts.
• Improved responsive layouts for mobile attachments, file previews, admin tables, and settings dialogs.
