 # Changelog
 
+## [0.1.0](https://github.com/Krasner/Img2Num/compare/cpp-v0.2.0...cpp-v0.1.0) (2026-10-07)
+
+
+### ⚠ BREAKING CHANGES
+
+* **core:** prevent holes during SVG generation ([#429](https://github.com/Krasner/Img2Num/issues/429))
+* **core:** img2num::labels_to_svg now returns std::string instead of char*. Callers using the C++ API must update their code to capture the return value as std::string and remove any associated std::free / delete[] calls. Callers using the C binding (cimg2num) are unaffected at the ABI level but should use img2num_free_svg to deallocate the returned buffer.
+* **api:** remove draw_contour_borders from labels_to_svg ([#283](https://github.com/Krasner/Img2Num/issues/283))
