Release digest: May 25 - June 1, 2026 (Week 22)

Added

AuthProxy (Release v2.4.0): Source/Aspire class library (Aspire.Hosting 9.5.2) with AuthProxyResource : ContainerResource pointing at cratis/authproxy and a full set of fluent extension methods on IResourceBuilder<T> where T : IResourceWithEnvironment — works on both container and project resources
AuthProxy (Release v2.4.0): OidcProviderType enum (Custom, Microsoft, Google, GitHub, Apple) in the Aspire library — standalone, no dependency on the AuthProxy web project
AuthProxy (Release v2.4.0): Documentation/aspire/index.md — how-to guide covering container vs project resource setup, all With* extension methods, the OidcProviderType enum, tenant selection, invites & lobby, identity details resolution, resource-based endpoint references, and cross-links to the existing configuration reference
AuthProxy (Release v2.4.0): publish-nuget job in .github/workflows/publish.yml using OIDC trusted publishing (NuGet/login@v1) — packs and pushes only Source/Aspire/Aspire.csproj as Cratis.AuthProxy.Aspire to NuGet.org; runs independently of the Docker pipeline

Components (Release v2.0.0): Added PrimeReact 10 and 11 compatibility for the token layer — each --cratis-* token resolves the PrimeReact v11 design token (@primeuix/themes) first and falls back to the v10 theme variable, so the same build works across both majors.
Components (Release v2.0.0): Added pt, ptOptions, unstyled, and className forwarding on single-widget wrappers.

Components (Release v2.0.0): Added a migration guide covering peer dependency changes, visual changes, provider setup, and optional styling capabilities.
Components (Release v2.0.0): Added a Storybook Styling toolbar with previews for Lara Dark Blue, Lara Light Blue, Custom palette, Unstyled bare, and Unstyled + Tailwind pt.
