Interface:

Smooth highlighting of tabs and settings features when hovering the cursor over them within the mod's settings menu.

Default transparency is now 30%.

Descriptions for each feature are now much more detailed (a new, comprehensive description has been added, while a brief summary remains at the bottom).

A new "Culling" tab has been introduced, consolidating all culling-related features; this helps declutter the settings menu and improves its overall appearance.

The black search bar has been removed and replaced with a transparent one that matches the menu's background color.

The default color theme for the settings menu is now "Ocean" instead of "Amethyst."

A new option has been added to the "Mobs & Entities" tab, allowing you to disable the light emitted by any entity to which Radonium adds lighting.

With the new "decoration thinning percentage" slider, you can now control how much decor is removed.

Compatibility:

Compatibility with the Polytone mod and its latest versions has been added.

Improvements:

Optimization of lighting and particles has been improved for when a large number of blocks are broken.

The "aggressive VRAM mode" has been improved.

Now, proper light is cast onto the player's hand and the object they are holding, and it no longer glitches.

The slider on the right can now be moved using a cursor or a finger.

New features:

A new light-culling feature for underwater and above-water environments (if the player is underwater, they won’t see light from above the water, and if the player 
is above water, they won’t see light from underwater).

Light has been added to the flying fire projectile, as well as to various other instances.

Additionally, blazes now cast a beautiful light of their own.
