-**Features**
-
-- Add ``TreeSequence.extend_edges`` method that extends ancestral haplotypes
-  using recombination information, leading to unary nodes in many trees and
-  fewer edges. (:user:`petrelharp`, :user:`hfr1tz3`, :user:`avabamf`, :pr:`2651`)
-
-- Add ``Table.drop_metadata`` to make clearing metadata from tables easy.
-  (:user:`jeromekelleher`, :pr:`2944`)
-
 **Bugfixes**
 
 - Fix to the folded, expected allele frequency spectrum (i.e.,
   `TreeSequence.allele_frequency_spectrum(mode="branch", polarised=False)`,
   which was half as big as it should have been. (:user:`petrelharp`,
   :user:`nspope`, :pr:`2933`)
