 	  optimization is not strictly necessary with modern Coq versions.
 
 	* Added companion matrix of a polynomial `companionmx p` and the
-	  theorems: companionmxK, map_mx_companion and companion_map_poly
+	  theorems: companionmxK, map_mx_companion and companion_map_poly.
+
+	* Extended generic theory about monotonocity (*mono* and *homo* lemmas).
+
+	* Added: homoW_in, inj_homo_in, mono_inj_in, anti_mono_in,
+	  total_homo_mono_in, homoW, inj_homo, monoj, anti_mono,
+	  total_homo_mono.
+
+	* Extended theory about homo and mono for leq/or and Num.le
+
+	* Renamed: (together with the _in suffix counterpart)
+	  mono_inj -> incr_inj
+	  nmono_inj -> decr_inj
+	  leq_mono_inj -> incnr_inj
+	  leq_nmono_inj -> decnr_inj
+	  homo_inj_ltn_lt -> incnr_inj
+	  nhomo_inj_ltn_lt -> decnr_inj

+	  nhomo_inj_ltn_lt -> inj_nhomo_ltnr
+	  homo_mono -> ler_mono
+	  nhomo_mono -> ler_nmono
+
+	* Added sorted_lt_nth, ltn_index, sorted_le_nth, leq_index.
+
+	* Generalized extremum_spec and its theory, added extremum and
+	  extremumP, generalizing arg_min for an arbitrary eqType with an
+	  order relation on it (rather than nat). Redefined arg_min and
+	  arg_max with it.
+
+	* Added [arg minr_( i < n | P ) F] and [arg maxr_( i < n | P ) F]
+	  with all their variants, following the same convention as for nat.
+
+	* Added missing contra* lemma: contra_neqN, contra_neqF,
+	  contra_neqT, contra_neq_eq, contra_eq_neq.
+
+	* Addded missing seq theorems: take_subseq, drop_subseq
 
 	* Reshuffled theorems inside files and packages:
 	  * countalg goes from the field to the algebra package
