why statement based replication method (repmodel) for table (pg_dist_partition) is not given in the doc for v12.1?

[AbhijeetPandey4Tech]

I have upgraded my Citus version to 12.1 and saw by default statement based replication model was in place, upon checking the document for v12.1 the repmodel column shows just two methods - 2pc for ref tables i.e 't' and postgresql streaming replication 's'

but my tables are showing 'c' repmodel,

my question is - why it is not present in the documentation? Can someone please refer where I can find more details about it?
