+ ### (Issue #2096 ) Introduction of flipped relation symbol for ` Relation.Binary.Bundles.Preorder `
826
+
827
+ * Previously, the relation symbol ` _∼_ ` was (notationally) symmetric, so that its
828
+ converse relation could only be discussed * semantically* in terms of ` flip _∼_ `
829
+ in ` Relation.Binary.Properties.Preorder ` , ` Relation.Binary.Construct.Flip.{Ord|EqAndOrd} `
830
+
831
+ * Now, the symbol ` _∼_ ` has been renamed to a new symbol ` _≲_ ` , with ` _≳_ `
832
+ introduced as a definition in ` Relation.Binary.Bundles.Preorder ` whose properties
833
+ in ` Relation.Binary.Properties.Preorder ` now refer to it. Partial backwards compatible
834
+ has been achieved by redeclaring a deprecated version of the old name in the record.
835
+ Therefore, only _ declarations_ of ` PartialOrder ` records will need their field names
836
+ updating.
837
+
838
+ * NB (issue #2098 ) the corresponding situation regarding the ` flip ` ped
839
+ relation symbols ` _≥_ ` , ` _>_ ` has not (yet) been addressed.
