- June 2, 2021 Reviewed all schedules and repositioned RU before all other commands within any line using the RU command
- August 10, 2021 New HH.Rtn from Volodya which fixes the issue where HS/HL does not get saved into the bfile, so if their avg files are lost, it cannot be recreated. Currently this is being tested on 039 and 111.
- January 22, 2022 Updated re-sb.rtn received from Volodya. Fixes the issue where SB Brewer can potentially drop out of schedule during an RU. A scenario can exist where it looks for a line of code in the re-sb.rtn that was thought to be unnecessary and removed. Adjustments made and re-sb.rtn updated in the program master directory.

- March 24, 2021 the wrong fr.rtn was pushed (Was still in development) which caused issues with resetting the micrometers
