Largely, nothing. Some people have publicly observed that certain Municipal Liaisons have been stripped of their ML status. Some have further speculated that something strange is going on.
In actuality, we sent out a message to MLs in early February and asked for folks to step forward with their intentions to continue as MLs (or not) in 2024. Those who definitively said they plan to not continue are the people who we have gradually begun to reclassify on the forums. MLs who said definitively that they will continue in 2024, as well as those who said they were still thinking about it, have maintained their current status pending final decision about their 2024 plans.
