+## [4.1.4] - 2026-01-29
+
+### Added
+- **New `turbo` restore profile** 🚀 - Maximum restore speed, matches native `pg_restore -j8`
+  - `ClusterParallelism = 2` (restore 2 DBs concurrently)
+  - `Jobs = 8` (8 parallel pg_restore jobs)
+  - `BufferedIO = true` (32KB write buffers for faster extraction)
+  - Works on 16GB+ RAM, 4+ cores
+  - Usage: `dbbackup restore cluster backup.tar.gz --profile=turbo --confirm`
+
+- **Restore startup performance logging** - Shows actual parallelism settings at restore start
+  - Logs profile name, cluster_parallelism, pg_restore_jobs, buffered_io
+  - Helps verify settings before long restore operations
+
+- **Buffered I/O optimization** - 32KB write buffers during tar extraction (turbo profile)
+  - Reduces system call overhead
+  - Improves I/O throughput for large archives
+
+### Fixed
+- **TUI now respects saved profile settings** - Previously TUI forced `conservative` profile on every launch, ignoring user's saved configuration. Now properly loads and respects saved settings.
+
+### Changed
+- TUI default profile changed from forced `conservative` to `balanced` (only when no profile configured)
+- `LargeDBMode` no longer forced on TUI startup - user controls it via settings
+
+## [4.1.3] - 2026-01-27
+
+### Added
+- **`--config` / `-c` global flag** - Specify config file path from anywhere
+  - Example: `dbbackup --config /opt/dbbackup/.dbbackup.conf backup single mydb`
+  - No longer need to `cd` to config directory before running commands
+  - Works with all subcommands (backup, restore, verify, etc.)
+
 ## [4.1.2] - 2026-01-27

 ### Potato Profile (`--profile=potato`) 🥔
 **Easter egg:** Same as conservative, for servers running on a potato.
 
+### Turbo Profile (`--profile=turbo`) 🚀
+**NEW! Best for:** Maximum restore speed - matches native pg_restore -j8 performance.
+
+**Settings:**
+- Parallel databases: 2 (balanced I/O)
+- pg_restore jobs: 8 (like `pg_restore -j8`)
+- Buffered I/O: 32KB write buffers for faster extraction
+- Optimized for large databases
+
+**When to use:**
+- Dedicated database server
+- Need fastest possible restore (DR scenarios)
+- Server has 16GB+ RAM, 4+ cores
+- Large databases (100GB+)
+- You want dbbackup to match pg_restore speed
+
+**Example:**
+```bash
+dbbackup restore cluster backup.tar.gz --profile=turbo --confirm
+```
+
+**TUI Usage:**
+1. Go to Settings → Resource Profile
+2. Press Enter to cycle until you see "turbo"
+3. Save settings and run restore
+
