 - The BLAZES option will assign events that are exported directly from the software [BLAZES](https://git.research.dezeeuw.ca/tyler/blazes)
 - Moved the updating logic to a seperate file for better reusability and generalization
 - Fixed 'Toggle Status Bar' having no effect on the visibility of the status bar
+- Fixed a bug when updating optode positions that would prevent .txt files from being selected. Fixes [Issue 54](https://git.research.dezeeuw.ca/tyler/flares/issues/54)
+- Fixed a missing dependency in the standalone application when attempting to use an .xlsx file to update optode positions
