 ### [Unreleased]
 
-...
+#### Added
 
+- Hidden rows and columns now are **NOT** exported by default; checkboxes
+  to enable export of hidden cells (per row and/or per-column) are
+  now provided
 
 ### [1.1.0] - 2019-01-08
 
 #### Added
 
- * New information box on the form indicates the sheet and range of
-   cells currently set to be exported
- * New warning added, if the separator appears in the data to be exported;
-   this should minimize accidental generation of files that cannot be
-   used subsequently, due to the excess separator characters

+  cells currently set to be exported
+- New warning added, if the separator appears in the data to be exported;
+  this should minimize accidental generation of files that cannot be
+  used subsequently, due to the excess separator characters
 
 #### Changed
 
- * UserForm now reappears in its prior location when closed
-   and re-opened, instead of always reappearing in the center
-   of the Excel window.
- * Selection of multiple areas now results in an "<invalid selection>"
-   message in the new information box; and, greying out of the 'Export'
-   button instead of a warning message after clicking 'Export'
- * Selection of entire rows/columns now sets for export the intersection
-   of the selection and the UsedRange of the worksheet. Selection of an
-   entire row/column outside the UsedRange of the worksheet gives an
-   "<invalid selection>" message in the new information box and disables
-   the 'Export' button

 #### Fixed
 
- * Userform now disappears when a chart-sheet is selected, and reappears
-   when a worksheet is re-selected. Userform will silently refuse to open
-   if triggered when a chart-sheet is active
- * Error handling added around folder selection and output file opening
-   for write/append
