We've fixed a mistake that caused the user-entered settings to fail to save.

We've fixed a bug that got past us in the last build. Now the sight planner again shows you the names of the objects in the sky!

We've updated the magnetic deviation model for 2025, and fixed some minor typos and bugs in the app.

We've been busy fixing bugs and making the app better!

We've found that in Dark mode the app does not display properly. While we are fixing this problem, we have this build which is always in Light mode.

We've fixed a display issue where a control's color was the same as the background, fixed some missing icons, and fixed some bugs.

We've fixed a bug when reviewing sights and using archived sights.

Updated the world magnetic model to 2020.
