Changelog

4.0.0 - 2026-07-06

Changed

• Major performance rewrite across the whole package
• set/get/getOrNull/removeValue: paths are compiled once and cached per isolate; traversal is a tight, allocation-free loop (2.6–4.5x faster)
• visit: the quadratic per-node ancestors allocation is gone; one reused ancestor stack per traversal (26x faster at depth 1000, ~400x at depth 5000)
• ls: shared path buffer instead of per-node string interpolation (~3x faster)
• deepCopy: bulk map cloning with nested patching (~2x faster)
• deeplEquals: lockstep iteration without per-entry allocation (~20% faster)
• Added JsonPathSegment and compileJsonPath for pre-compiled paths
• Added a benchmark suite under benchmark/

Breaking changes

• VisitProp uses positional parameters now: migrate json.visit(({key, value, parent, ancestors}) {...}) to json.visit((key, value, parent, ancestors) {...})
• visit's ancestors argument is a live, read-only view that is only valid during the callback; copy it with List.of(ancestors) if you retain it
• Path strings are validated eagerly when first compiled: an invalid segment anywhere in a path throws Invalid path segment ... even if the walk would previously have failed earlier with a missing-path error or returned null
