What are the major differences between the Erlang 26.x and 27.x series that could be relevant to Trend Micro's detection or blocking behavior

Could you clarify the differences between the Erlang 26.x series and the Erlang 27.x and 28.x series? Trend Micro appears to block Erlang 27.x and 28.x, but not Erlang 25.x or 26.x. Are there any significant changes in these newer versions that could explain why they are being blocked?
