The user guide opened from the app now uses the site's new address (www.ja1bus.com). Features and behavior are unchanged.

Released October 13, 2026Link to this version

Added "Sequential number" (001.png) and "Sequential number + description" (001_Open settings.png) to the file naming options. Images for manuals and guides can be saved with names that keep them in the order you took them.
With "Sequential number + description", a window opens when you save so that you can enter a description, which becomes part of the file name.
The capture dialog and the image editor now show where the image is saved. With sequential numbers, you can switch the folder with "Change folder".

The buttons in the capture dialog are now the same size in two columns and three rows, with the most frequently used buttons in the bottom row.
Settings now shows only the boxes for the selected file naming, and detailed explanations can be expanded. The window scrolls if it does not fit on the screen.
The folder last used with "Save as" is now remembered even after AreaShot exits.

Added "MIT License", "Source code" and "Third-party notices" to the lower left of Settings. You can view the full license text in the app.

Fixed "Save as" sometimes replacing an existing file without asking when an unsupported extension was entered and the selected type's extension was added.
Fixed the original image sometimes being lost, or a partly written file being left, when saving failed partway (for example, when the disk was full).
File name patterns that start with a reserved Windows name, such as CON.capture, are now changed to a usable name (CON_.capture) when saving.
