+## [0.3.0] — 2026-07-24
+
+### Changed
+
+- Runtime-aligned Microsoft platform dependencies now carry per-target-framework
+  version floors instead of a single shared floor. In a library a
+  `PackageReference` version is a minimum NuGet forces on every consumer
+  (lowest-applicable-version resolution), so the previous single `10.0.x` floor on
+  `Microsoft.Extensions.DependencyInjection.Abstractions` forced `net8.0` consumers
+  off their own LTS servicing line. The `net8.0` assembly now floors it at `8.0.2`
+  and the `net10.0` assembly at `10.0.10`, each on its own runtime-aligned line.
+  `Spectre.Console` and `Spectre.Console.Cli` version independently of the
+  runtime and remain single common floors.
+- Updated NuGet dependencies to their latest stable versions: `Spectre.Console`
+  0.57.2 (and the test-only `Spectre.Console.Testing` 0.57.2) and
+  `Microsoft.SourceLink.GitHub` 10.0.301, plus the test-only
+  `Microsoft.Extensions.DependencyInjection` 10.0.10 and `Microsoft.NET.Test.Sdk`
+  18.8.1. `Spectre.Console.Cli` remains 0.55.0 — its latest stable, which only
+  requires `Spectre.Console >= 0.55.0`.
