[0.3.2] - 2026-01-11¶

Print Macros: Drop-in print!/println! replacements that shadow std macros with rich markup support.
print!, println!, eprint!, eprintln! - styled output macros
print_raw!, println_raw!, eprint_raw!, eprintln_raw! - raw output (no parsing)
rprint!, rprintln! - non-shadowing aliases
Spinner Styles: 80+ spinner styles for SpinnerColumn:
SpinnerColumn::new().with_style(SpinnerStyle::Moon)
Emoji spinners: Moon, Earth, Clock, Hearts, Star
ASCII spinners: Arrow, BouncingBar, GrowHorizontal, Aesthetic
SpinnerStyle::all_names() to list available styles

Progress Bars: Significantly improved Progress module (Python-rich parity):
Added BarColumn with distinct characters for filled, pointer, and empty states.
Implemented pulsing animation for indeterminate tasks (unknown total).
Added refresh(), start(), and stop() methods for flicker-free rendering.
Added run() method for context-manager style usage.
Added sub-character precision (smooth updates) using 8th-block unicode characters.
Added expand option for full-width progress bars.

Documentation: Fixed track() demo glitch where output would wrap and stack incorrectly.
Example: docs_track example works reliably on all terminal widths.

CI: Resolved Rustfmt failures and Windows-specific line ending mismatches in byte-level tests.

README: Polished Documentation section with high-fidelity badges and corrected links.

Professional Visuals: Integrated high-fidelity terminal animations via VHS.
Visual README: Overhauled landing page with centered branding and feature gallery.
Interactive Tapes: Added .tape files for automating all project demonstrations.
Security Audit: Completed full codebase scan for secrets and sensitive data.
Project Logo: Official Rocket Crab branding integrated across all docs.

Layout: New tiling layout engine (Layout, split_row, split_column).
Live: Live display updating (Live context manager).
Prompt: Interactive user input handling (Prompt.ask).
Inspect: Object introspection tool (inspect()) for Rust and Python objects.
Filesize: Utilities for human-readable file sizes (decimal, binary).
Bindings: Full Python bindings for all new modules.
Benchmarks: Comparisons for Layout and Inspect scenarios.
CI: Strict enforcing of atomic commits and formatting.

Syntax Highlighting Performance: Optimized Syntax rendering speed by 3.5x (14.5s -> 4.2s for 1000 iterations) by using OnceLock for global syntax/theme set caching. This resolved a major bottleneck where large binary dumps were reloaded on every instantiation.

Core Library: Implemented Rust port of Rich's core components:
Console with style and color support.
Table with auto-sizing and unicode borders.
Tree for hierarchical data.
Panel and Rule layouts.
Progress bars with spinners.
Markdown rendering via pulldown-cmark.
Syntax highlighting via syntect.
Traceback beautiful error reporting.
Logging handler.
Python Bindings: Full ABI3-compatible Python extension module (fast_rich) exposing all core components.
Benchmarks: Comprehensive suite proving 2x-24x performance improvements over Python rich.
Logging: 24x faster.
Columns: 23x faster.
Table: 17x faster.
Tree: 11x faster.
Markdown: 9x faster.
