This page lists the incompatible changes to the style scheme file format.
The <author>
tags are no longer supported, so you should
remove them.
The support for the parent-scheme
attribute has been removed. It
was unused. If you relied on it, copy and adapt the content of the parent
scheme.
The support for the line-background
attribute (for the
<style>
tag) has been removed.
You need to add the kind
attribute (for light/dark), a new
mandatory attribute.
The version
attribute of the <style-scheme>
element is no longer supported, so you should remove it.
The parser is now a bit more strict, check if there are warning messages printed in the terminal if a style scheme fails to load.
