+### Fixed

+- **Windows uninstaller crash — `StrReplaceAll` not found** — NSIS requires functions called from the `Uninstall` section to be defined as `Function un.FunctionName`. `StrReplaceAll` was defined as a plain function, causing `makensis` to abort with "Call must be used with function names starting with 'un.'". Renamed to `un.StrReplaceAll` and updated both call sites. ([#119](https://github.com/iamvirul/deepdiff-db/pull/119))
