+# Version 1.1.4
+
+- Fixed some display text to now display the correct information
+- A new option under Analysis has been added to export the data from a specified participant as a csv file. Fixes [Issue 19](https://git.research.dezeeuw.ca/tyler/flares/issues/19), [Issue 27](https://git.research.dezeeuw.ca/tyler/flares/issues/27)
+- Added 2 new parameters - TIME_WINDOW_START and TIME_WINDOW_END. Fixes [Issue 29](https://git.research.dezeeuw.ca/tyler/flares/issues/29)
+- These parameters affect the visualization of the significance and contrast images but do not change the total time modeled underneath
+- Fixed the duration of annotations edited from a BORIS file from 0 seconds to their proper duration
+- Added the annotation information to each participant under their "File information" window
+- Fixed Macs not being able to save snirfs attempting to be updated from BORIS files, and in general the updated files not respecting the path chosen by the user
+
+
+# Version 1.1.3
+
+- Added back the ability to use the fOLD dataset. Fixes [Issue 23](https://git.research.dezeeuw.ca/tyler/flares/issues/23)
+- 5th option has been added under Analysis to get to fOLD channels per participant
+- Added an option to cancel the running process. Fixes [Issue 15](https://git.research.dezeeuw.ca/tyler/flares/issues/15)
+- Prevented graph images from showing when participants are being processed. Fixes [Issue 24](https://git.research.dezeeuw.ca/tyler/flares/issues/24)
+- Allow the option to remove all events of a type from all loaded snirfs. Fixes [Issue 25](https://git.research.dezeeuw.ca/tyler/flares/issues/25)
+- Added new icons in the menu bar
+- Added a terminal to interact with the app in a more command-like form
+- Currently the terminal has no functionality but some features for batch operations will be coming soon!
+- Inter-Group viewer now has the option to visualize the average response on the brain of all participants in the group. Fixes [Issue 26](https://git.research.dezeeuw.ca/tyler/flares/issues/24)
+- Fixed the description under "Update events in snirf file..."
+
+
+# Version 1.1.2
+
+- Fixed incorrect colormaps being applied
+- Added functionality to utilize external event markers from a file. Fixes [Issue 6](https://git.research.dezeeuw.ca/tyler/flares/issues/6)

 # Version 1.1.1
