 ## [Unreleased]
 
+## [0.4.4] - 2026-06-16
+
+UI motion polish, high refresh rate, performance fixes, and security improvements release. Git tag **`0.4.4`**.
+
+### Added
+
+- **Motion tokens core (UI-A1)** — `QueryaMotion` core durations and curves, providing a single source of truth for all animations.
+- **Token adoption (UI-A2)** — replace magic/scattered duration and curve literals with standardized tokens.
+- **Smoother transitions (UI-A3)** — menu/dropdown enter fade+scale, dialog blur/scale retune, tree height animation (`QueryaAnimatedExpand`), and workspace tab content cross-fade (`QueryaCrossFadeStack`).
+- **High refresh rate (UI-A4)** — unlock native ProMotion on macOS 14+, active Hz logging at startup, and FPS/Hz debug overlay.
+- **Reduced motion setting (UI-A5)** — Preferences toggle (`Full` / `Reduced` / `Off`) and automatic OS reduced-motion configuration matching.
+- **Docs & performance checks (UI-A6)** — per-OS measured refresh-rate verification table, DevTools performance checklists, and release QA items.
+- **SQLite Database Support Plan (0.4.5)** — design and implementation roadmap for local SQLite file connector support.
+
+### Fixed
+
+- **Memory: SQL Result Capping (Issue #184)** — PostgreSQL and MySQL query execution now limits client memory usage by applying query LIMITs database-side and streaming rows using `rowsStream` (breaking early).
+- **Performance: MongoDB Client-side Pagination (Issue #185)** — uses `SelectorBuilder` skip/limit operators on the server instead of client-side stream buffering.
+- **Performance: N+1 secure storage lookups (Issue #186)** — parallelizes connection secrets hydration on startup.
+- **Performance: Redis Key Scanning round-trips (Issue #187)** — runs type and TTL lookups concurrently for key batches.
+- **Security: Theme Remote Installation SSRF (Issue #183)** — parses and filters IPv6 and private/loopback/multicast/mapped hosts using `InternetAddress.tryParse`.
+- **UX: Focus leak on QueryaCrossFadeStack** — wraps inactive children in `ExcludeFocus` and `ExcludeSemantics` to prevent tab-indexing into off-screen tabs.

+7. **Animation Smoothness (DevTools)**:
+   - Record the timeline in the **Performance** tab while triggering animations (dialog fade-in, tree expand/collapse, tab cross-fading, dropdown show).
+   - Ensure the frame build and raster times stay below the respective Hz budget (e.g., < 8.3 ms on a 120 Hz monitor).
+8. **Reduced Motion**:
+   - Turn on "Reduce Motion" in your OS settings or select **Preferences → Appearance → Motion → Off** (or **Reduced** for 50% speed).
+   - Verify that transitions complete instantly (**0 ms** for Off) or are appropriately shortened.

+# Planned release 0.4.5 — SQLite Database Connector
+
+**Status:** **Planned** (GitHub milestone [**0.4.5**](https://github.com/QueryaHub/Querya-Desktop/milestones), epic **#194**).  
+**Depends on:** **0.4.4** UI motion polish (shipped).
+
+Theme: Add support for local SQLite database file connections. This allows users to select `.db`, `.sqlite`, or `.sqlite3` files from their disk, browse their schema, run arbitrary SQL queries in a dedicated workspace, and view paginated table grids.
+
+## Why
+
+- **Highly Requested**: SQLite is one of the most requested local database connectors by developers who want to inspect local app databases, cache files, or development databases.
+- **Zero-Increase Bundle Size**: SQLite support can be fully implemented using the existing `sqflite_common_ffi` package already bundled for `LocalDb`, keeping the binary lightweight and dependency-clean.
+
+## Scope
+
+| ID | Issue | Scope | Summary |
+|----|-------|--------|---------|
+| **SQL-S1** | #195 | `sqlite`, `core` | **Core Driver** — implement `SqliteConnection` wrapping `sqflite_common_ffi` and `SqliteService` to manage active connection handles to local files. |
+| **SQL-S2** | #196 | `sqlite`, `core` | **Schema Resolver** — read tables, views, and indexes metadata via `sqlite_master` catalog tables and column info via `PRAGMA table_info`. |
+| **SQL-S3** | #197 | `sqlite`, `ui` | **Connection Form** — create `SqliteConnectionForm` integrating native OS file picker (`file_selector` package) and a "Read-Only" safety toggle. |
+| **SQL-S4** | #198 | `sqlite`, `ui` | **Sidebar Integration** — render SQLite connections and their schema nodes in `ConnectionsPanel` connection tree. |
+| **SQL-S5** | #199 | `sqlite`, `ui` | **Workspace & Table View** — implement `SqliteWorkspaceHome` (SQL editor) and a paginated `SqliteTableView` database browser. |
+| **SQL-S6** | #200 | `sqlite`, `test` | **Test Coverage** — write unit tests for connection driver and widget/integration tests for workspace actions. |
+
+## Suggested PR order
+
+1. SQL-S1 & SQL-S2 — SQLite connection driver and catalog schema parser
+2. SQL-S3 — Connection form with file picker dialog
+3. SQL-S4 — Sidebar connection tree integration
+4. SQL-S5 — SQLite SQL workspace editor and paginated data table
+5. SQL-S6 — Tests and verification
+
+## Out of scope for 0.4.5
+
+- **SQLCipher / Encrypted SQLite files** — deferred to **0.4.6+** (requires compiling/linking SQLCipher binary dependencies).
+- **In-Memory SQLite Database connections** — deferred.
+- **Local DB migration to another engine**.

+- [ ] **Motion Full** — set to **Full**, check that all animations run normally.
+- [ ] **Motion Reduced** — set to **Reduced**, check that animations are visibly faster (durations cut in half).
+- [ ] **Motion Off** — set to **Off**, check that animations complete instantly (0 ms).
+- [ ] **OS Reduced Motion** — enable reduced motion in OS settings. The app should automatically disable animations (acting as Off) regardless of in-app Full/Reduced settings (OS setting wins).
