Example: From 1.8 to 1.9, command blocks changed substantially. ▪ Commands will not work on newer versions that changed command formatting.
Example: If a command was made in 1.8.0, it will most likely work in 1.8.2 or 1.8.9, etc. ▪ Some commands might work on versions that came after they were published.
