+- Support key prefixes for Linux desktop environments (e.g. `[gnome]`, `[kde]`

+- Support custom key prefixes (e.g. `[win10]` or `[test]`) in properties files.
+  (issue #649)
+- Support multi-prefixed keys (e.g. `[dark][gnome]TitlePane.buttonBackground`).

     `com.formdev.flatlaf.intellijthemes.materialthemeuilite` from `Flat<theme>`

   - Removed `Gruvbox Dark Medium` and `Gruvbox Dark Soft` themes.
+- Prefixed keys in properties files (e.g. `[dark]Button.background` or
+  `[win]Button.arc`) are now handled earlier than before. In previous versions,
+  prefixed keys always had higher priority than unprefixed keys and did always
+  overwrite unprefixed keys. Now prefixed keys are handled in same order as
+  unprefixed keys, which means that if a key is prefixed and unprefixed (e.g.
+  `[win]Button.arc` and `Button.arc`), the one which is last specified in
+  properties file is used.\
+  Following worked in previous versions, but now `Button.arc` is always `6`:
+  ~~~properties
+  [win]Button.arc = 12
+  Button.arc = 6
+  ~~~
+  This works in new (and old) versions:
+  ~~~properties
+  Button.arc = 6
+  [win]Button.arc = 12
+  ~~~
