[0.5.0]- 2026-04-27

This is a major release introducing multi-file patch support, git binary diff handling, and no_std compatibility.

Breaking Changes

• #73 The crate is now no_std by default. Patch::to_bytes() and PatchFormatter::write_patch_into() now require the std feature. Add features = ["std"] to restore them.
• #46 Color support is now behind the color feature flag. Previously color was always available. Now PatchFormatter::with_color() requires enabling the color feature. The underlying implementation switched from nu-ansi-term to anstyle.

Added

• #55 #59 #61 #66 #74 #76 Multi-file patch support. Parse and apply unified diff and git diff output containing multiple files, including create, delete, modify, rename, and copy operations. Git binary patches (literal and delta) are supported behind the binary feature flag.
• #80 New apply example demonstrating multi-file patch application.

Fixed

• #51 #82 Patch::from_str / from_bytes no longer error on trailing non-patch content after a complete hunk, matching GNU patch and git apply behavior.
• #65 Return an error instead of panicking on non-UTF-8 escaped filenames when parsing as str.
• #47 Fix quoted filename escaping: handle \a, \b, \f, \v, 3-digit octal escapes (\0xx–\3xx), and quote all control characters.
• #83 Fix arithmetic overflow panic when parsing hunk headers with extremely large range values.
