This page lists various breaking and non-breaking theme changes that providers of custom themes will want to incorporate.

2025.12.0

The way the options screens work has been reworked.

All elements that start with any of these names should be entirely removed:

  • OptionsGame
  • OptionsGraphics
  • OptionsSound
  • OptionsInput
  • OptionsLyrics
  • OptionsThemes
  • OptionsRecord
  • OptionsAdvanced
  • OptionsNetwork
  • OptionsWebcam
  • OptionsJukebox

Copy (and if desired: modify) all elements that start with these names from Deluxe.ini or Modern.ini:

  • OptionsSub
  • OptionsNetworkLegend

2026.2.0

Themes now support extending (across themes) and inheritance (within a theme).

Extending

Instead of duplicating an entire theme, a theme only needs to:

  • [Theme].BaseTheme = Modern (or any other theme that does not define BaseTheme)
  • Define the changed elements completely with all attributes.
  • Define any elements you want to disable with a single attribute Enabled = 0. This only works on optional elements, these usually end in *Text1/2/3/... or *Static1/2/3/....

Inheritance

Basically instead of doing this:

Theme code with lots of duplication ``` [MainButtonSolo] X = 95 Y = 270 W = 150 H = 50 Tex = Button Color = ColorLight DColor = ColorDark Type = Transparent Texts = 1 Reflection = 1 ReflectionSpacing = 15 DeSelectReflectionSpacing = 280 Fade = 1 FadeText = 1 SelectH = 150 FadeTex = ButtonFade FadeTexPos = 0 [MainButtonMulti] X = 250 Y = 270 W = 150 H = 50 Tex = Button Color = ColorLight DColor = ColorDark Type = Transparent Texts = 1 Reflection = 1 ReflectionSpacing = 15 DeSelectReflectionSpacing = 280 Fade = 1 FadeText = 1 SelectH = 150 FadeTex = ButtonFade FadeTexPos = 0 ```

you can write MainMuttonMulti as:

[MainButtonMulti]
Inherits = MainButtonSolo
X = 250

In this case, MainButtonSolo can also be defined by the BaseTheme.

Note: Enabled = 0 can’t be inherited. In the above example, if you were to set [MainButtonSolo].Enabled = 0, this doesn’t magically also disable the MainButtonMulti.

2026.3.0

Any theme element whose name starts with SongCarousel, SongSlotMachine, SongSlide or SongMosaic is obsolete.
