I've spent some time in the past year dealing with changes to my code due to Python v2->v3 and R v3->v4 changes. It got me curious as to some of the older languages that are still in use.
I know COBOL still sees occasional updates and functionality upgrades. I would assume that their mission-critical nature makes those changes smaller and more backward-compatible, but I don't really know and couldn't find it with a web search.
What and when were the last changes to COBOL that was on the same rough order as the Python 2->3 changes?

What was changed is a long list, therefore not shown.
COBOL 2002:
Removed 18 language elements that were made obsolete in COBOL 85.
Added 54 reserved words that would cause syntax errors if not used in conformance with the 2002 standard.
Added the FLAG-85 directive to identify 10 cases where the same syntax could have different results than the 1985 standard.
