+- Fixed the pre-release workflow publishing its source distribution under the released version instead of the pre-release one. `build_sdist.sh` ran `git reset --hard` and `git clean -xdf`, which discarded the `pyproject.toml` version that the preceding step had just stamped, so a run that built `1.1.0a0` wheels built a `1.1.0` sdist and PyPI rejected it as a duplicate. `pre_build.sh` already resets the tree, so the second reset is gone. It also no longer destroys uncommitted work when the script is run locally. ([#413](https://github.com/qBraid/pyqasm/pull/413))
 - Added a `SECURITY.md` with a private vulnerability disclosure path. There was no documented way to report one, leaving a public issue or a guessed email address as the only options. Reports now go through this repository's GitHub security advisory form. ([#383](https://github.com/qBraid/pyqasm/pull/383))
