• Improved Electron theme backgrounds and dialog focus handling for better visual polish and accessibility.
• Refined Electron startup logic and DMG packaging configuration, including centered DMG layout and a switch to gray background for installer visuals.

Internal

• Updated Electron Builder configuration and related scripts to support refined packaging and theme behavior.
• Consolidated and cleaned up desktop-specific auth context and action definitions across server and client layers.

What's Changed

AI Features & Reliability

• Enabled AI actions (e.g., table summaries, schema explanations, tab title generation) to use the cloud proxy on desktop clients, improving consistency and reliability across platforms.
• Fixed an error in AI model execution that caused failures during tab title generation and other AI-driven insights—now handles model errors gracefully and surfaces clearer feedback.

Query Audit Stability

• Resolved two critical issues preventing the query audit feature from opening or functioning correctly on desktop, including entitlement checks and UI initialization errors in the sidebar navigation.

Internal

• Refactored AI execution pathways to consistently route through the cloud AI proxy, simplifying logic and unifying behavior across web and desktop environments.

What's Changed

Features

• Added support for using the cloud AI proxy for AI-powered actions in the desktop environment, enabling more reliable and scalable AI execution across features like table summaries, schema explanations, column tagging, and tab title generation.

Fixes

• Fixed an error that prevented the query audit panel from opening correctly in the SQL console.
• Resolved an AI model execution error that caused failures during tab title generation and other AI-driven operations.

Improvements

• Unified AI request routing to consistently use the cloud AI proxy across SQL console components—including Copilot modes, saved queries sidebar, and tab management—improving reliability and maintainability.

Internal

• Updated i18n translation files (English, Spanish, Japanese, Chinese) to reflect new or adjusted AI-related UI strings.

What's Changed

Improvements

• Enhanced table structure tooltip: Column details (e.g., data type, nullability, description) are now merged into the structure tooltip in the table browser, providing richer context without navigating away from the overview.
• Improved email verification UI: The verify email panel layout is widened and action buttons (e.g., “Resend email”, “Go to dashboard”) are horizontally aligned for better visual consistency and usability.

Localization

• Centralized i18n locales: Shared translation strings across the web app have been consolidated into packages/i18n, improving maintainability and consistency for English, Spanish, Japanese, and Chinese locales.

Internal

• Codebase refactoring: Several components and AI-related modules (e.g., column tagging, cloud proxy model, tab title generation) were updated to support the unified tooltip and localization changes—enabling cleaner extensibility and reducing duplication.

What's Changed

Features & Improvements

• Guest sign-in experience: Added loading state during guest authentication and initialized user ID plumbing across auth flows and session recovery components.
• Connection dialog redesign: Refactored the connection creation/edit dialog into a sectioned side navigation layout for improved clarity and usability.
• TLS configuration UI: Refined TLS controls in the connection dialog, including updated certificate field presentation and form organization.
• Data source filtering: Improved metadata filtering UI for data sources—enhanced search, filter controls, and localization support across all languages.
• Connection cards: Added a “Prod” badge to indicate production data sources; refined card actions and updated the delete confirmation dialog for better user feedback.

Fixes

• SQL Console stability: Fixed database list loading failure when first entering the SQL Console with a ClickHouse connection.

Internal

• Merged coordinated PRs (#279, #280) to align frontend changes across auth, connections, and SQL console modules.

What's Changed

Fixes

• Resolved MCP-related errors preventing proper initialization and auto-opening of the MCP proxy in Electron and web environments.
• Fixed session recovery synchronization issues on desktop platforms.

Improvements

• Redesigned the sign-in page for improved usability and consistency across desktop and web, including updated translations for English, Spanish, Japanese, and Chinese.
• Enhanced the SQL console result inspector panel with refined layout and behavior for better data exploration.

Internal

• Updated Electron app dependencies and package metadata to support latest MCP integration changes.

What's Changed

Fixes

• Fixed an error that prevented users from opening email verification links during sign-in, sign-up, and email verification flows.

Improvements

• Updated localization files across English, Spanish, Japanese, and Chinese to ensure consistent and accurate messaging for authentication UI components.

Internal

• Integrated plugin-related dependencies and configurations as part of the plugins feature merge.
