# Changelog

All notable changes to this project are documented here.

## [3.0.1] - 2026-04-16

### Changed

- **Rewrote all documentation**: The README, DOCUMENTATION, and CHANGELOG all read way too robotic and stiff — rewrote everything from scratch to sound like a human actually wrote it.
- **Expanded technical docs**: `DOCUMENTATION.md` now covers the full rendering pipeline step-by-step (normal estimation, Z-buffering, font bitmap layout, 3-point light rig, projection), with a configuration reference table and an actual example of how the bitmap font data maps to pixels.
- **README overhaul**: Cleaner structure, controls in a table, straightforward descriptions of what the project does instead of overengineered marketing-speak.

## [3.0.0] - 2026-04-16

### Added

- **Interactive TUI**: You can now change text, toggle settings, and control rotation without restarting the program. The terminal is put into raw, non-blocking mode via `termios.h` so keypresses register instantly.
- **Live text input**: Type alphanumeric characters while it's running and the 3D model updates immediately to show your new text.
- **Keybinding bar**: A help overlay at the bottom of the screen shows all available controls (space to pause, c for color mode, w/s for speed, etc.).
- **TUI module**: Added `tui.h` and `tui.c` as a separate module to keep the input handling code out of the renderer.

### Changed

- **Cleaned up comments**: Removed the old Doxygen-style block comments that were mostly restating what the code already said. Replaced them with shorter inline comments focused on explaining *why*, not *what*.
- **Makefile cleanup**: Simplified build targets, improved the comments so they're actually useful.

### Fixed

- **Terminal restore on exit**: The program now properly restores terminal settings (canonical mode, echo) when you quit or hit Ctrl+C. Before this, interrupting the process could leave your terminal in a broken state where it wouldn't echo input or handle line editing correctly.
