 ## [0.2.0] - 2026-01-22
 
-### Changed
-- Refactored core traversal logic to a **single-pass, in-memory tree construction** algorithm. This visits every file exactly once, replacing the previous $O(N \times Depth)$ behavior with $O(N)$.
-- Switched default CSV output to use the `csv` crate for robust escaping (fixes issues with filenames containing commas).
-- Optimized JSON output to use zero-copy serialization, improving performance and memory usage.
-
 ### Added
-- Added `MANUAL.md` with comprehensive usage documentation.
-- Added comprehensive test suite (unit and integration tests).
-- Added performance benchmarks using `criterion`.
+- **Comparison Mode**: Added `--compare` flag to display total size vs. non-ignored size (respecting `.gitignore`).
+- **Unit Control**: Added `--units <binary|decimal>` flag to toggle standard IEC (MiB) vs. SI (MB) unit systems.
+- **Precision Control**: Added `--precision <number>` to control decimal places in output (default: 2).
+- **Physical vs. Logical Distinction**: Explicitly show **Apparent Size** (logical) and **Disk Usage** (actual blocks consumed) in all output formats.
+- **Release Assets**:
+    - Project **Makefile** for easy system-wide installation via `make install`.
+    - Universal **`scripts/release.sh`** for generating optimized binaries, man pages, shell completions, and `.deb` packages.
+    - Official **man page** (`sized.1`) for standard Unix documentation documentation.
+    - Updated **Homebrew Formula** for tap-based distribution.
+- **Improved Errors**: Graceful handling for inaccessible directories (e.g., system protected folders) with "Access Denied" status.
+- Added a full user guide in `MANUAL.md`.
+
+### Changed
+- **Performance Overhaul**:
+    - Replaced serial/par-bridge traversal with `ignore::WalkParallel` for true multi-threaded directory scanning.
+    - Implemented **dynamic thread allocation** to balance CPU load between directory breadth and depth.
+    - Refactored core logic to a **single-pass, in-memory tree construction** algorithm ($O(N)$ complexity).
+- **Architecture**: Refactored the project into a usable Rust library (`src/lib.rs`) and a thin CLI wrapper (`src/main.rs`).
+- **Dependencies**:
+    - Switched to `byte-unit` for more flexible and accurate unit formatting.
+    - Replaced `walkdir` with `ignore` for faster traversal and native `.gitignore` support.
+    - Replaced `atty` and `chrono` with standard library features and the lightweight `time` crate.
+- **Serialization**: Optimized JSON and CSV output for zero-copy performance and detailed metric reporting.
+
+### Fixed
+- Resolved performance bottleneck in extremely deep directory structures.
+- Fixed inconsistent total size reporting when `.gitignore` was active.
 
 ### Removed
-- Removed `walkdir` dependency (replaced by `ignore::WalkBuilder` for all traversal).
-- Removed `humansize` (consolidated to `byte-unit`).
-- Removed `chrono` (replaced with lightweight `time`).
-- Removed `atty` (unused).
-
+- Dependency on `walkdir`, `humansize`, `chrono`, and `atty`.
 
 ## [0.1.0] - 2026-01-22
 
 ### Added
-- Core directory traversal and size calculation logic.
-- Parallel processing using `rayon` for high performance.
-- Rich table output format using `comfy-table` with colored entries.
-- Recursive depth control via `-d`/`--depth`.
-- Minimum size filtering via `-m`/`--min-size`.
-- Multi-column sorting support (`--sort`).
-- Relative path display by default, with `-f`/`--path-full` override.
-- "Total size" summary with dual units (Binary/Decimal) and block counts.
-- Concurrency control via `-j`/`--threads`.
-- `.gitignore` and `.ignore` file support via `-i`/`--ignore`.
-- Multiple output formats: Text (Table), CSV, JSON (`--format`).
-- Save to file functionality with auto-naming (`--save`).
-- Shell completion generation (`--completions`).
+- Initial release with core directory traversal and size calculation.
+- Basic parallel processing using `rayon`.
+- Rich table output via `comfy-table`.
+- Basic filtering (`--min-size`, `--depth`) and sorting (`--sort`).

 ## Installation
 
-Currently, `sized` can be installed from source:
+### From Binaries (Recommended)
+Download the latest pre-compiled binaries from the [Gitea Releases](https://gitea.speelman.ca/gamertan/sized/releases) page.
 
+### From Source
 ```bash
-git clone <repository_url>
+git clone https://gitea.speelman.ca/gamertan/sized.git
 cd sized
-cargo install --path .
+make install # Installs binary and man page
 ```
 
 ## Basic Usage
 
-By default, `sized` analyzes the current directory recursively and displays a table of the immediate children, sorted by name.
+By default, `sized` analyzes the current directory recursively and displays a table of the immediate children.
 
 ```bash
-sized
+sized [path]
 ```
 
-To analyze a specific path:
+### Key Concepts
+- **Apparent Size**: The logical size of the entry (file length). This is what most file explorers show.
+- **Disk Usage**: The actual physical space consumed on disk (Blocks * 512 bytes). This is the "true" footprint.
+- **Blocks**: The actual filesystem blocks allocated. Useful for identifying sparse files or filesystem overhead.
+
+### Path Display
+- **Relative Path** (Default): `sized` shows paths relative to the current directory.
+- **Full Path**: Use `-f` or `--path-full` to see absolute paths (e.g., `/Users/dev/project`).
+- **Relative Toggle**: Use `--path-relative` to explicitly force relative paths (useful if overriding aliases).
+
+### Depth Control (`-d` / `--depth`)
+By default, `sized` shows the immediate children of the target directory (depth 0). You can increase the recursion depth shown in the output.
+
 ```bash
-sized /path/to/directory
+# Show current directory and its children's children
+sized -d 1
 ```
 
-The output includes:
-- **Type**: Icon indicating if it's a directory (📁) or file (📄).
-- **Name**: The relative path to the entry.
-- **Size**: Human-readable size (e.g., 10 MB, 2.5 GB).
-- **% of Parent**: The percentage of the total size of the *current view* (immediate children) that this entry consumes.
-- **Last Modified**: Time since the file was last modified.
-
-### Total Size Header
-The header displays the total size of the scanned directory in both Binary (MiB/GiB) and Decimal (MB/GB) units, along with the total block count.
+> [!NOTE]
+> Regardless of the display depth, `sized` always calculates the *total* size of all subdirectories accurately by traversing the entire tree.
 
 ## Filtering and Sorting
 
 ### Sorting (`--sort`)
-Sort the output table by a specific column.
+Sort the output table by a specific column. `sized` supports multi-column sorting.
 
-**Syntax**: `--sort <COLUMN:DIRECTION>`
-- **Columns**: `name`, `size`, `type`
-- **Directions**: `asc` (ascending), `desc` (descending)
+**Syntax**: `--sort <COLUMN:DIRECTION>,[COLUMN:DIRECTION]`
+- **Columns**: `name` (n), `size` (s), `type` (t), `blocks` (b)
+- **Directions**: `asc` (a), `dsc` (d)
 
 **Examples**:
 ```bash
 # Sort by size (largest first) - Default behavior
-sized --sort size:desc
+sized --sort size:dsc
 
-# Sort by name (A-Z)
-sized --sort name:asc
+# Primary sort by Type, secondary sort by Size descending
+sized --sort type:asc,size:dsc
 ```
 
 ### Minimum Size (`-m` / `--min-size`)
-Hide entries smaller than a specific size to reduce noise.
+Hide entries smaller than a specific size to reduce noise. Supports standard units (KB, MB, GB, etc.).
 
-**Examples**:
 ```bash
-# Show only files/dirs larger than 10 MB
-sized -m 10MB
-
-# Show only files/dirs larger than 1 GB
-sized --min-size 1GB
+# Show only items larger than 100MB
+sized -m 100MB
 ```
 
-### Depth Control (`-d` / `--depth`)
-Limit the recursion depth for the *calculation*. Note that the display currently shows immediate children, but this flag controls how deep `sized` looks to calculate directory sizes.
-*(Note: Deeply nested directory sizes are always fully calculated unless limited)*
+### Limiting Results (`-n` / `--number`)
+Limit the number of rows displayed in each table.
 
 ```bash
-sized -d 2
+# Show only the top 10 largest items
+sized --sort size:dsc -n 10
 ```

 ## Advanced Features
 
-### Path Display
-- **Default**: Relative paths (`./folder`)
-- **Full Path**: Use `-f` or `--path-full` to see absolute paths (`/users/name/folder`).
-- **Relative Path**: Use `--path-relative` to explicitly force relative paths.
+### Unit System (`--units`)
+Switch between Binary (IEC) and Decimal (SI) units for the output.
 
-### Concurrency (`-j` / `--threads`)
-`sized` uses parallel processing. By default, it uses a number of threads equal to your CPU cores. You can limit this for system stability or increase it (though usually not clear).
+- **Binary** (Default): GiB, MiB, KiB (multiples of 1024).
+- **Decimal**: GB, MB, KB (multiples of 1000).
 
 ```bash
-# Limit to 4 threads
-sized -j 4
+# Use decimal units (SI)
+sized --units decimal
 ```
 
-### Gitignore Support (`-i` / `--ignore`)
-Respect `.gitignore` and `.ignore` files. This is useful for checking the size of a project *as it would be committed*, ignoring `target/`, `node_modules/`, etc.
+### Precision (`--precision`)
+Specify the number of decimal places for formatted sizes. Defaults to `2`.
 
 ```bash
+# Higher precision for small files
+sized --precision 4
+```
+
+### Comparison Mode (`--compare`)
+Compare the total physical size of a directory against its "filtered" size (files that would be included in a commit, respecting `.gitignore`).
+
+```bash
+# Show both total and non-ignored metrics
+sized -i --compare
+```
+This adds **"Filtered"** rows and headers to the output, allowing you to see how much space is consumed by ignored files (like `node_modules` or `target`).
+
+### Gitignore Support (`-i` / `--ignore`)
+Respect `.ignore` and `.gitignore` files during traversal. This is highly recommended for developer workflows.
+
+```bash
+# Exclude git-ignored files from calculations
 sized -i
 ```
 
-### Exporting Data (`--save`)
-Save the output directly to a file. If you use `_AUTO_` (or provide no argument to the flag), it generates a filename with the current timestamp.
+### Concurrency (`-j` / `--threads`)
+`sized` uses parallel processing powered by `rayon` and `ignore`. By default, it uses a number of threads equal to your logical CPU cores.
 
 ```bash
-# Save to a specific file
-sized --save report.txt
+# Limit to 4 threads on a high-core system
+sized -j 4
+```
 
-# Save to a timestamped file (e.g., 20250122-120000_sized_report.txt)
+### Exporting Data (`--save`)
+Save the output directly to a file. If no filename is provided, `sized` generates a timestamped one (e.g., `sized_report_20260122_1430.txt`).
+
+```bash
+# Save to an auto-generated file
 sized --save
+
+# Save to a specific path
+sized --save reports/my_audit.json --format json
 ```

+# Project Release Process
+
+This document defines the process for versioning and distributing the `sized` project independently of the Git hosting provider (GitHub, GitLab, Gitea).
+
+## 1. Versioning and Tagging
+
+The project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). 
+
+1.  Synchronize the version in `Cargo.toml`.
+2.  Update `CHANGELOG.md` with the release notes.
+3.  Commit and create a git tag:
+    ```bash
+    git tag -a v0.2.0 -m "Release v0.2.0"
+    ```
+
+## 2. Asset Generation
+
+The `scripts/release.sh` script is the authoritative way to generate release assets locally or in any CI environment. 
+
+```bash
+./scripts/release.sh
+```
+
+This script generates:
+-   **Optimized Binary**: The production-ready `sized` executable.
+-   **Documentation**: The `sized.1` man page.
+-   **Shell Completions**: Scripts for Bash, Zsh, and Fish.
+-   **System Installers**: A `.deb` package for Debian-based Linux distributions.
+
+All assets are gathered in the `dist/v<VERSION>/` directory.
+
+## 3. Distribution Channels
+
+### crates.io
+To update the project on the central Rust registry:
+```bash
+cargo publish
+```
+
+### System Package Managers
+For Homebrew, GitLab, or Gitea-based distribution:
+1.  Push the git tag to your SCM.
+2.  Run the release script to generate assets.
+3.  Attach the contents of the `dist/` folder to your SCM's "Release" or "Tag" entry.
+4.  Update downstream formulas (like `homebrew-tap`) with the new source URL and SHA256 of the generated tarball.
+
+## 4. Automation & Hooks
+
+To automate asset generation locally, you can use a git `post-checkout` or a wrapper script. Since gitea and gitlab use different CI formats, it is recommended to simply call `./scripts/release.sh` within your preferred CI runner (e.g., `gitlab-ci.yml` or `gitea-actions`).
+
+## 5. Manual Installation
+For system-wide installation from source, use the `Makefile`:
+```bash
+make install
+```
+Defaults to `PREFIX=/usr/local`. Overridable via `PREFIX=/your/path make install`.
