     createHref() now normalizes generated pathnames to one leading slash, including absolute URLs and hrefs generated with baseURL. Leading slashes in root wildcard values no longer round-trip unchanged. Pathname wildcard values containing standalone . or .. segments now throw CreateHrefError with details.type === 'invalid-pathname-wildcard'.

     Pass path fragments without extra leading slashes, and resolve any intended dot segments before generating an href. Multi-segment paths, internal and trailing slashes, and dotted filenames remain supported.

      createHref('/*path', {
     -  path: '/docs/../readme.md',
     +  path: 'readme.md',
      }, { baseURL: 'https://example.com/' })

   • Declare package modules as side-effect-free.

   • Reject backslashes in createHref() hostname variables and wildcards so generated URLs retain the intended hostname.

   • Count variable scans and capture comparisons toward maxMatchWork so matching stops when optional or wildcard patterns exceed the configured work limit.

     Route matching now uses delimiter-bounded params and a bounded state compiler (see #11651). Pathname params possessively capture through hyphens but stop at raw / or ., so UUIDs remain intact and createHref() percent-encodes dots in param values for round-tripping. Patterns such as /:year-:month must migrate to one inseparable param such as /:date, or place captures in separate delimiter-bounded segments.

     Patterns may contain any number of separated wildcards and optional groups without eagerly expanding variants or using backtracking regular expressions. Adjacent wildcards, empty optionals, params followed by non-delimiter text, and ambiguous adjacent optional capture schemas now throw ParseError. Repeated capture names remain valid: the last participating capture wins in params, while paramsMeta retains every capture in source order.

     Static pattern text is decoded during matching, while raw and percent-encoded / and . retain distinct structural meaning. Matchers also accept configurable pattern-size, matcher-size, and match-work limits through MatcherOptions.limits; exceeding a limit throws MatcherResourceError with structured details.

     createHref(pattern, params, searchParams) now accepts an options object as its third argument. Move existing search parameters to createHref(pattern, params, { searchParams }).

     Matchers now accept relative URL strings when an absolute baseURL is provided to match() or matchAll(). createHref() accepts the same baseURL option and returns path-relative references for same-origin targets while leaving cross-origin targets absolute. The searchParams option accepts both typed plain objects and URLSearchParams; repeated URLSearchParams entries retain their order.
