0.6.0

Added

Export Presets

• Added support for reloading an externally changed file or continuing with the in-editor version.
• Added shared editor hooks for browser autosave, desktop document bridging, schema export generation, and asset path handling.

• Released the Electron desktop package as titanbase-desktop@0.1.0.

Desktop App

• Added the free OSS apps/desktop Electron application using the shared visual editor and schema packages.
• Added file-backed open, save, Save As, SQL import, compare, migration-draft export, and all schema export workflows through native dialogs.
• Added a narrow typed preload bridge with context isolation, renderer sandboxing, and Node integration disabled.
• Added native application menus and shortcuts, recent files, OS file-open events, drag and drop, unsaved-change prompts, and safe close handling.
• Added deterministic desktop file-state and filesystem safety helper tests.
• Added a larger default desktop window, draggable topbar regions, runtime app icons, and Electron Builder targets for macOS dmg/zip, Windows nsis, and Linux AppImage/deb.
• Added dedicated desktop icon assets in apps/desktop/build.

• Added desktop app documentation covering status, local-first behavior, security model, limitations, and roadmap.
• Added a shared desktop file adapter to @titanbase/editor while preserving existing browser picker and download behavior.
• Clarified that Titanbase Desktop loads its bundled local renderer in production and does not depend on the hosted website.
• Changed desktop Save As defaults to use a slugified project-name .titan.json filename.
• Added source-kind context to the editor file status so desktop users can distinguish blank, template, .titan.json, and SQL-imported schemas.

0.5.0

Added

Schema Diff

• Added the framework-independent diffSchemas() API to @titanbase/core.
• Added deterministic project, table, column, relation, index, enum, and enum-value changes with stable matching and conservative rename detection.
• Added destructive and breaking change classification, matching warnings, summary counters, and semantic metadata filtering.
• Added a local Compare action and schema diff modal with grouped changes, severity badges, before/after values, object selection, and invalid-file handling.

PostgreSQL Migration Drafts

• Added the deterministic generatePostgresMigrationDraft() API to @titanbase/export-postgres.
• Added draft SQL for table, column, constraint, foreign-key, index, enum-addition, rename, and comment changes.
• Added destructive and breaking metadata plus explicit review warnings for data loss, casts, inferred constraint names, locking, and enum limitations.
• Added a migration preview flow from Schema Diff with warning review, SQL copy, and .sql download actions.
• Added focused migration-draft tests and PostgreSQL import-to-migration integration coverage.

Changed

• Extracted shared PostgreSQL identifier, type, column, table, index, and foreign-key formatting helpers for consistent full exports and migration drafts.

0.4.0

Added

Editor

• Added per-action call-to-action affordances on the start screen cards (Create schema, Browse templates, Open file, Import SQL) that reveal on hover.
• Added an explicit responsive viewport configuration for correct mobile rendering and safe-area handling.
• Added actionable project, table, column, relation, index, enum, and metadata diagnostics.
• Added diagnostic entity context, help text, severity counts, issue codes, and direct object selection.
• Added local PostgreSQL .sql import entry points to the start screen, toolbar, empty canvas, and Project Overview.
• Added a non-blocking import report for unsupported SQL and a failure state that preserves the current schema.

Importers

• Added @titanbase/import-postgres with deterministic browser-safe PostgreSQL DDL parsing.
• Added support for enums, tables, column and table constraints, foreign keys, indexes, comments, quoted identifiers, and namespaces.
• Added line-aware warnings for unsupported statements, expression indexes, unsupported constraints, and unresolved references.
• Added 25 importer tests, including a PostgreSQL import/export integration scenario.

Changed

• Reworked the start screen action cards into a balanced, uniform grid with consistent icons, a refined "Recommended" badge, and equal heights.
• Made the start screen scrollable on mobile and stacked the hero, header, and cards for small viewports.
• Compacted the editor toolbar (smaller logo, tighter spacing and controls) and moved the Website and Docs links to the end of the toolbar as icon-only buttons with tooltips.
• Shortened the toolbar "Import SQL" action label to "Import".
• Made the editor toolbar horizontally scrollable so all actions stay reachable on narrow screens.

Fixed

• Fixed the start screen cards rendering as an unbalanced 3 + 1 layout; they now reflow cleanly across breakpoints (4 → 2 → 1 columns) with no orphaned card.
• Fixed the editor canvas not panning on touch devices by removing the oversized shell min-width that pushed content beyond the viewport.
• Fixed the inspector sidebar being clipped off-screen and its collapse control becoming unreachable on narrower windows.
• Fixed the start screen header overlapping the Docs/GitHub actions on small screens.
• Fixed the oversized website mark icon by setting explicit dimensions.

• Improved Prisma identifier mapping, enum defaults, unique constraints, and ambiguous relation handling.
• Improved Drizzle dependency ordering, reserved identifiers, safe defaults, minimal imports, and cyclic relation warnings.
• Updated README and roadmap to reflect the available local exporters and current product scope.

Fixed

• Prevented generated Prisma relations from referencing non-unique target fields.
• Prevented duplicate Prisma unique constraints when a column is already unique.
