v0.3.0

Added

• Global Control Overrides: Introduced thread-safe set_override(level: ColorLevel) and clear_override() APIs, allowing developers to programmatically bypass environment cascades and explicitly lock down terminal styling preferences at runtime.

• Hex Color Construction: Added Color::from_hex(...) for creating RGB colors from "#RRGGBB" or "RRGGBB" hex strings, including support for compile-time const color definitions

• CSS Colors: Added CSSColor struct, providing the complete set of CSS named colors as Color constants. All standard 140 CSS color names and aliases are now available for convenient compile-time color selection.

• Panel Layouts: Added a generic Panel layout container supporting nested frames, custom titles, and automatic padding calculated via unicode-width.

Removed

• Apple Terminal Strikethrough Fallback: Removed the custom character-stitching fallback loop for macOS Terminal.app to resolve layout corruption, string data bloat, and ANSI tracking de-synchronization. The library now universally emits standard SGR 9 escape sequences across all environments.

v0.2.0

Added

• Apple Terminal Strikethrough Fallback: Implemented an automated fallback engine for macOS Terminal.app that dynamically embeds Unicode combining long stroke characters (\u{0336}) through printable text strings to resolve its native lack of \x1b[9m ANSI sequence support.

• Zero-Allocation Lazy Evaluation: Introduced StyledRef to lazily stream ANSI text styling configurations directly to formatting targets via fmt::Display implementation, completely eliminating heap allocations on formatting passes.

Breaking Changes

• Reference-Bound Style::apply API: The signature of Style::apply now accepts arguments by shared reference (&T) instead of taking ownership by value. Passing owned primitives or numeric constants manually now explicitly requires a reference borrow prefix (e.g., style.apply(&34) instead of style.apply(34)). Normal string literals remain unaffected as they naturally satisfy the reference type bound (&str).

v0.1.0

Added

• Multi-Tier Colors: Full support for 16 standard ANSI colors, 256-color palettes, and 24-bit TrueColor RGB.
• Smart Downsampling: Automatic fallback math to translate rich RGB colors down to 256 or 16 colors depending on terminal support.
• Environment Detection: Strict compliance with NO_COLOR, FORCE_COLOR, TTY status checking (stdout.is_terminal()), COLORTERM, and TERM.
• Fluent API: Builder pattern interface (Style::new()) to programmatically stack properties like colors, bold, italic, underline, dim, strikethrough, and inversion.
• Logging Macros: make_style! for declarative style creation and sprintln! for direct formatting output.
• Performance: Zero external dependencies and thread-safe environment caching via OnceLock.
