 ## [Unreleased]
 
+### Added
+- Allowed double clicking on entries in the "jump to preprocessed files" dialogue window to open the file.
+- Preprocessor comment blocks can now fold each if/ifdef/elseif/else block separately, rather than the entire block from #if -> #endif
+- Added a plugin settings screen
+- Preprocessor fold regions
+   - can optionally collapse inactive regions by default (based on preprocessor condition checks)
+   - can optionally collapse all by default
+- Preprocessor condition checking
+   - now support chained checks e.g. `//#if this && that`
+   - now support loader checks e.g. `//#if FABRIC && !FORGE`
+   - now correctly checks conditions that need to be false, such as the #if/elseif's preceding an #else/elseif block being tested
+- Preprocessor jump to file action
+   - now also correctly moves you to the same caret position and scrolls to it
+   - can now differentiate files based on the preprocessor conditions that apply at the caret position
+   - can now optionally hide those differentiated results
+   - can now press the down arrow from the search bar to navigate to the list (keyboard navigation streamlining)
+- can optionally highlight formatting/clarity problems such as:
+   - #if directive not being indented further than it's containing preprocessor block
+   - #else/elseif/endif directives not having a matching indent with their initial #if directive 
+- Added an option to disable the `//$$ ` insertion on new lines
+<img width="750" height="405" alt="image" src="https://github.com/user-attachments/assets/dc364ea4-3502-45e0-88ec-e12c8c5bee76" />
+- Added an action to toggle all preprocessor comments `//$$ ` for the selected lines
+- Added an action to toggle all preprocessor comments `//$$ ` for the entire preprocessor block the caret is within
+- Further keyboard navigation improvements to file jump action
+
+### Fixed
+- Fixed sorting of entries in the "jump to preprocessed files" dialogue window.
+- Fixed kotlin k2 mode not registering correctly and always ignoring the optional kotlin-plugin.xml, and thus no working kotlin file folding in k2
+- Fixed/improved `PreprocessorNewLineHandler` noticably
+- Several bugs from the previous preprocessor condition checking fixed, including the `prevSibling` iterating not correctly finding previous directives
+- Correct version checking has replaced some logic that used `mainVersion` for all files, `mainVersion` is still a fallback if this fails
+
+### Updated
+- Changed preprocessor comment styling to have more muted colours & use italics
+<img width="381" height="218" alt="image" src="https://github.com/user-attachments/assets/2009d6aa-baa6-4117-adcf-c53e47941b83" />
+- Added support for override files within `versions/<version>/src/` to the "jump to preprocessed files" action.
+- Improved the visual clarity of the list in the "jump to preprocessed files" dialogue window.
+- Improved keyboard navigation of the "jump to preprocessed files" dialogue window.
+- Having ! before a condition identifer is no longer highlighted as an error, e.g. `!FABRIC`
