The popular open-source e-book management tool, Calibre, has just released version 8.15, bringing improvements in the Comments editor, bug fixes, and updates to its news-source catalog.

The e-book viewer adds a small enhancement: hovering over a highlight now displays the date it was created. The Comments editor receives two updates focused on text handling. Case-change operations now preserve as much existing formatting as possible, improving accuracy when editing styled text.

In addition, new keyboard shortcuts have been introduced for all case-change actions. Users can select text, open the right-click menu, and view the new shortcut list.
