 Notable changes are recorded here.
 
+# WoofWare.Myriad.Plugins 2.1.45, WoofWare.Myriad.Plugins.Attributes 3.1.7
+
+The NuGet packages are now attested to through [GitHub Attestations](https://github.blog/2024-05-02-introducing-artifact-attestations-now-in-public-beta/).
+You can run `gh attestation verify ~/.nuget/packages/woofware.myriad.plugins/2.1.45/woofware.myriad.plugins.2.1.45.nupkg -o Smaug123`, for example, to verify with GitHub that the GitHub Actions pipeline on this repository produced a nupkg file with the same hash as the one you were served from NuGet.
+
+# 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.

 Some helpers in [Myriad](https://github.com/MoiraeSoftware/myriad/) which might be useful.
 
-These are currently somewhat experimental, and I personally am their primary customer.
+Currently implemented:
-The `RemoveOptions` generator in particular is extremely half-baked.
+
+* `JsonParse` (to stamp out `jsonParse : JsonNode -> 'T` methods).
+* `JsonSerialize` (to stamp out `toJsonNode : 'T -> JsonNode` methods).
+* `HttpClient` (to stamp out a [RestEase](https://github.com/canton7/RestEase)-style HTTP client).
+* `GenerateMock` (to stamp out a record type corresponding to an interface, like a compile-time [Foq](https://github.com/fsprojects/Foq)).
+* `CreateCatamorphism` (to stamp out a non-stack-overflowing [catamorphism](https://fsharpforfunandprofit.com/posts/recursive-types-and-folds/) for a discriminated union).
+* `RemoveOptions` (to strip `option` modifiers from a type) - this one is particularly half-baked!
 
 If you would like to ensure that your particular use-case remains unbroken, please do contribute tests to this repository.
 The `ConsumePlugin` assembly contains a number of invocations of these source generators,
 so you just need to add copies of your types to that assembly to ensure that I will at least notice if I break the build;
 and if you add tests to `WoofWare.Myriad.Plugins.Test` then I will also notice if I break the runtime semantics of the generated code.
