🐛 Fixes

• 3c0aa37 fix: restore Roslyn 4.8 band so .NET 8 SDK users work again @glennawatson

🔗 Full Changelog: v3.0.0...3.1.0

🙌 Contributions

💖 Thanks to all the contributors: @glennawatson

⚠️ Breaking change — Roslyn 4.8 / 4.12 support dropped

3.0.0 ships only the roslyn4.14 and roslyn5.0 analyzer bands. The roslyn4.8 and roslyn4.12 bands were removed, because per the Visual Studio 2022 lifecycle only 17.14 (Roslyn 4.14) remains a serviced VS 2022 baseline (17.8 / Roslyn 4.8 and 17.12 / Roslyn 4.12 are end of support).

Minimum requirements (updated)

Action required: build with Visual Studio 2022 17.14+ / a Roslyn 4.14+ SDK, and reference ReactiveUI 23.2.28 or later. If you must stay on an older toolchain, remain on the 2.x line of this package.

🗞️ What's Changed
