I am working on the assumption that the Readme referred to is the one on this page: https://knowledge.windriver.com/en-us/000_Products/000/010/010/000/000_Wind_River_Linux_6.0.0.20 Do we try to list all defects fixed in every release? I have compared 18, 19, and 20 and find a mixture. LIN6-6919 and LIN6-7027 are fixed in 18, but not 19 or 20. There are some fixed only in 19, and only in 20, and some in both 19 and 20. There are many that are fixed in 18, and 19, but not 20.
