 Notable changes are recorded here.
 
-# WoofWare.Myriad.Plugins 1.4 -> 2.0
+# WoofWare.Myriad.Plugins 2.1.33
+
+`JsonParse` can now deserialize the discriminated unions which `JsonSerialize` wrote out.
+
+# WoofWare.Myriad.Plugins 2.1.32, WoofWare.Myriad.Plugins.Attributes 3.1.4
+
+`JsonSerialize` can now serialize many discriminated unions.
+(This operation is inherently opinionated, because JSON does not model discriminated unions.)
+
+# WoofWare.Myriad.Plugins 2.1.20, WoofWare.Myriad.Plugins.Attributes 3.0.1
+
+We now bundle copies of the RestEase attributes in `WoofWare.Myriad.Plugins.Attributes`, in case you don't want to take a dependency on RestEase.
+
+# WoofWare.Myriad.Plugins 2.1.15
+
+The `GenerateMock` generator now permits a limited amount of inheritance in the record we're mocking out (specifically, `IDisposable`).
+
+# WoofWare.Myriad.Plugins 2.1.8
+
+No change to the packages, but this is when we started creating and tagging GitHub releases, which are a better source of truth than this file.
+
+# WoofWare.Myriad.Plugins 2.0
 
 This transition split the attributes (e.g. `[<JsonParseAttribute>]`) into their own assembly, WoofWare.Myriad.Plugins.Attributes.
 The new assembly has minimal dependencies, so you may safely use it from your own code.
