10.0.2

Added

• Document the historical Cmd module breaking changes between Fabulous 2.4.x and 10.0.1 (removed Cmd.ofSub/Cmd.dispatch, the Cmd.OfAsync/Cmd.OfTask relocations, and the two-continuation either signature) in docs/guides/migration.md (#1336, #1337, #1338, #1339).

Changed

• Bump the Microsoft.NET.Test.Sdk version from 18.9.0 to 18.10.0 in Directory.Packages.props (Repo Assist).
• Bump BenchmarkDotNet from 0.14.0 to 0.15.8 and Microsoft.NET.Test.Sdk from 18.10.0 to 18.10.1 in Directory.Packages.props (Repo Assist).
• Revert the FSharp.Core package version floor bump from 10.1.401 back to 10.0.100 in Directory.Packages.props, after CI (#1351, #1354) confirmed it triggers a NullReferenceException in Apple's ILStrip post-processing tool when building the net10.0-ios sample target, keeping the Microsoft.NET.Test.Sdk/BenchmarkDotNet bumps intact (Repo Assist, #1355).
• Suppress the 60 FS0044 deprecation warnings from MAUI's own [Obsolete] attributes on SwitchCell/EntryCell/Page.IsBusy/SafeArea by adding #nowarn "44" to Views/Cells/_Cell.fs, EntryCell.fs, SwitchCell.fs, Views/Pages/_Page.fs, ContentPage.fs, and Views/Layouts/_Layout.fs, ahead of the 10.0.2 release (Repo Assist, #1344).
• Replace the immutable Set-based subscription-diffing in Sub.Internal.diff/Sub.Internal.NewSubs.calculate with a mutable HashSet, avoiding repeated O(log n) tree-node allocations on every Program update cycle (Repo Assist, #1202).
• Optimize StackArray3.combine to avoid an intermediate array allocation when merging a Few-cased value with a Many-cased array, writing directly into the final result array instead of allocating via toArray/Array.append (Repo Assist, #1234).
• Bump the Avalonia package version from 12.1.1 to 12.1.2 in Directory.Build.props (Repo Assist, #1317).
• Bump the fabulous-avalonia template's default Avalonia/Avalonia.Desktop/Avalonia.Android/Avalonia.iOS/Avalonia.Themes.Fluent package versions from 11.3.0 to 12.1.1 in templates/avalonia/**/.template.config/template.json (@kant2002, #1321).
• Document that the fabulous-avalonia single-project template's net10.0-android/net10.0-ios target frameworks require the android/ios .NET workloads, and document the previously-unlisted desktop-only fabulous-avalonia-desktop template as a workload-free alternative, in the Avalonia tutorial, get-started guide, and templates README (Repo Assist, #1319, #1326).
• Add Windows-from-Visual-Studio debugging guidance (Solution Platform selector, MSIX-packaged vs. unpackaged apps) to the MAUI tutorial and get-started guide (#1306, #1307, #1308, #1309, #1310, #1334, #1335).
• Fix formatting and clarify instructions in the Avalonia get-started guide and tutorial (#1329, #1330, #1331).
• Replace the dead Discord "Contact us" link with a mailto link in the website header (#1313).

Fixed

• Add unit tests for StackArray3's add, get, find, and combine operations, covering the Few/Many representation transitions and error paths that previously had no test coverage (Repo Assist).
• Route exceptions thrown by the leading-edge emit call in DispatchThrottle.Dispatch to onError, matching the error handling already used by the timer callback and FlushAsync, so a throwing dispatch handler no longer crashes the caller's dispatch thread (Repo Assist).
