Hello Linux Geeksters. As you may know, RedNotebook is a journal app, with calendar support. Among others, it allows the users to add taggs, use bold and italic caracters, has support for images, spell check features, automatic saving and backup functions, and many others.

The latest version available is RedNotebook 1.10, which has been released recently, coming with the below changes:
- Write data to temporary files first to prevent corrupted month files.
- Add format button for monospace font. Automatically add the correct format for code blocks.
