bensadeh/tailspin 6.0.0 on GitHub

Highlight HEAD, CONNECT, and OPTIONS HTTP methods by default (#261, thanks @g0l4!)
Add builtin keyword highlighting for undefined, NULL, nil, NIL, NaN, FALSE, and TRUE
File truncation detection in follow mode
Support for parentheses in URL paths (e.g. Wikipedia-style URLs) with balanced parenthesis detection
Clear error message for --exec on Windows instead of a generic
failure (#232)

Fix zombie processes when using --exec by properly waiting on the child process after it exits
Surface the actual error when the stream processor fails during initial read, instead of a generic channel-receive error
Gracefully handle broken pipe (e.g. tspin | head) instead of panicking
--follow not working on certain filesystems (NFS, FUSE, Docker bind mounts, etc.) by replacing linemux with a polling-based file reader (#240)
Crash when reading files with non-UTF-8 content (#31)
URLs wrapped in parentheses or single quotes incorrectly including surrounding delimiters in the highlight
Files with symlinks in their path could not be opened consistently (#244, #134)
Quoted regions now highlight correctly while preserving inner
highlights (#171)

HighlighterBuilder methods now take owned self instead of &mut self, enabling full method chaining (e.g. Highlighter::builder().with_number_highlighter(...).build())
Differentiate between Regexp Errors and Aho-Corasick Errors
Feature-gate CLI dependencies (tokio, clap, rayon, etc.) so library consumers can use default-features = false to avoid compiling them

IPv6 highlighting is now opt-in via --extras ipv6 instead of being enabled by default
Breaking (CLI): --enable ip-addresses / --disable ip-addresses renamed to --enable ipv4 / --disable ipv4
Builtin keyword highlighting of true changed from red to green
Breaking (config): The quotes_token key in the [quotes] section of theme config files has been renamed to quote_token. Existing config files using the old key will silently fall back to the default (")
Breaking (crate): QuotesConfig renamed to QuoteConfig and its quotes_token field renamed to quote_token

Use SIMD-accelerated memchr for newline detection in buffered reader
Cache ANSI escape sequence finders using LazyLock statics instead of recreating per call
Reduced string allocations across highlighters by replacing format!() with write!(), eliminating per-match allocations, and increasing pre-allocation buffers

Enable LTO, single codegen unit, and strip = true for release builds
Trimmed and modernized dependencies: replaced async-trait with native async traits, miette with anyhow, ctrlc with tokio signals; removed uuid
