+## v20260101-06-run-checks-shift-multiselect-fix
+
+- Fixed Shift-click behavior on the Run Checks page to properly select a range of rows via checkboxes.
+- Prevented default browser text selection when using Shift during checkbox selection.
+- Implemented tracking of the last selected checkbox to enable continuous range selection.
+- Ensured multiselect only applies to checkbox interactions and not table row text.
