+## [4.0.0](https://github.com/mcarvin8/config-disassembler-node/compare/v3.4.4...v4.0.0) (2026-09-09)
+
+
+### ⚠ BREAKING CHANGES
+
+* **xml:** disassemble/reassemble/parseXml/verifyXmlRoundtrip now return Promises instead of resolving synchronously. Any caller that invoked these without awaiting the result must add await, or it will no longer wait for the file to actually be processed.
+* switch native bindings from Neon to napi-rs ([#19](https://github.com/mcarvin8/config-disassembler-node/issues/19))
+
