 # [23.10.1] - 2023/12/07
 * [UI]: Fixed issue where filter inputs required focus when they are opened on the project samples page. See [PR 1503](https://github.com/phac-nml/irida/pull/1503)
 * [UI]: Fixed bug preventing sorting and paging on the project members page. See [PR 1504](https://github.com/phac-nml/irida/pull/1504)
+* [Developer]: Fixed race condition where FastQC file processor would start on incomplete file by filtering out files on non complete sequencing runs. [PR 1506](https://github.com/phac-nml/irida/pull/1506)
  
 ## [23.10] - 2023/10/15
 * [Developer]: Added functionality to delete sequence files from file system when a sequence run is removed. [See PR 1468](https://github.com/phac-nml/irida/pull/1468)
