What's New in Aspire 13.5.4

Patch release for Aspire 13.5 that fixes Kafka health-check resource leaks, DevTunnel errors with automatically selected regions, misleading Azure emulator dashboard entries, and unintended changes to generated starter apps, plus Homebrew compatibility and Radius API diagnostic updates.

🐛 Fixes

• 📨 Kafka health checks leaked producers and polling threads — Each AppHost health-check execution created a new Kafka producer without disposing it, accumulating background threads over time. Health checks now reuse a producer per Kafka resource and dispose it with the AppHost, while keeping multiple Kafka resources independently configured. Fixes #20091. (#20094, backport of #20092, @davidfowl)

• 🌐 DevTunnels could fail when the region was selected automatically — Tunnel setup and health checks now use the cluster-qualified tunnel ID returned by the DevTunnel CLI for port operations and access queries. This fixes failures when a bare tunnel ID cannot be resolved for those operations. Regression introduced in 13.3. Fixes #18790. (#19853, backport of #19230, @Vladipz)

• ☁️ Emulator-only AppHosts showed an unused Azure environment — The dashboard now hides the azure-environment resource when no Azure resources require cloud provisioning, instead of leaving it visible in Not started. It remains visible for apps that combine local emulators with resources requiring Azure provisioning. No AppHost changes are needed. Fixes #19617. (#19998, backport of #19843, @eerhardt)

• 🧩 Starter app generation could alter unrelated JavaScript values — Dynamic port replacement could also replace matching numeric literals in bundled JavaScript, including Bootstrap timing values. Port substitutions are now restricted to localhost: URLs, preserving the original library files while still configuring the requested ports. Fixes #20030. (#20110, backport of #20031, @bart-vmware, @JamesNK)

• 🍎 Updated the Aspire Homebrew cask for Homebrew 6.x — Replaced deprecated cask URL and post-install syntax with the supported equivalents, resolving compatibility issues with current Homebrew while preserving install-channel metadata. (#20119, backport of #19965, @askpt, @joperezr)

• 🧪 Radius cloud-provider callback interfaces now carry the experimental diagnostic — IAwsRadiusProviderBuilder and IAzureRadiusProviderBuilder are now marked with ASPIRERADIUS003, matching the existing WithAwsProvider and WithAzureProvider methods. Code referencing these interfaces directly must now acknowledge the same experimental API diagnostic. (#19874, @sebastienros)
