1.4.3

• [CHORE] optimize encode traversal internals and hot paths with lower allocation overhead
• [CHORE] add internal KeyPathNode path caching for lazy materialization and dot-encoded path reuse

• [FIX] avoid mutating caller-owned root list/tuple elements when EncodeOptions.filter is callable
• [CHORE] remove unused KeyPathNode.total_length state to keep nodes lightweight
• [CHORE] expand encode regression and internal helper tests (path caching, list format generators, strict-null formatting, mutation safety)

1.4.2

1.4.2

• [CHORE] optimize decode by skipping dot-in-keys normalization when "%2" is not present in key segments

PyPI: https://pypi.org/project/qs_codec/1.4.2/

1.4.1

1.4.1

• [FIX] harden encoder traversal to an iterative implementation to avoid recursion-based crashes on very deep nested input
• [FIX] harden decode merge path (Utils.merge) with iterative traversal to prevent RecursionError on deep conflicting merges
