+# Version 1.8.0
+
+- Plugin Manager now supports checking and downloading plugin updates to ensure plugins can be updated
+- Plugin Manager now properly uninstalls plugins when requested rather than doing nothing
+- Installing plugins now displays a progress bar when downloading and no longer hangs the application when downloading a big plugin
+- Project loading now displays a loading message when loading big projects and no longer hangs the application when loading
+- New preferences options and menus are now available! All existing preferences have been moved into new sub categories
+- The UI preference category now has the Show Advanced Parameters preference
+- The Updates preference category has two ney options to prevent the automatic checking of application or plugin updates
+- The Theme category has remain untouched and all other preferences have been moved to the Processing category
+- Added a new preference in the Processing category called "Separate Events". This allows events to have their own values, and not be collapsed into a single value
+- Export To CSV Viewer export options now perform the actions they claim rather than having no functionality
+- Logs on a per participant basis are now available to be viewed from within the application
+- They can be accessed by right clicking a participant bubble and selecting "Show Logs". Logs will be empty if they have not been processed
+- Fixed a regression where opening a folder would no longer load all the files in that folder
+- Improved code stability and functionality

 # Version 1.7.1

 DESCRIPTION = """0. Raw ROI Comparison (run_inter_group_second_level_analysis)
 \nCompares one ROI's raw response magnitude between two independent groups (e.g. control vs. target) for a given condition, using Welch's t-test. A significant result means the two populations differ in this ROI's response magnitude for this condition. It does not tell you whether that difference is a real, localized, task-specific effect or a generic between-population difference - different overall vascular reactivity, arousal, or skull/scalp optical properties can produce the exact same statistical signature, and two independently recruited groups (especially patients vs. healthy controls) are considerably more likely to differ this way than two subsets of one study population.
