+## [v0.41.7] - 2026-04-18
+
+### Added
+
+- Optional **.NET SDK** installation via `--install-dotnet` (defaults to **.NET 10** LTS channel) and `--install-dotnet=8|9|10` on both **Desktop** and **Server** editions. Linux uses the Microsoft APT repository when available, with fallback to the official `dotnet-install.sh` script; macOS (Desktop) uses `dotnet-install.sh` under `~/.dotnet`.
+- Shell PATH support for user-local .NET (`DOTNET_ROOT`, `~/.dotnet`, `~/.dotnet/tools`) in `conf/zshrc-*.zsh` when `~/.dotnet` exists.
+
+### Changed
+
+- Roadmap and installation summary show **.NET** in the relevant step title when `--install-dotnet` is used, or when an existing **.NET SDK** is detected (Desktop step 5; Server **AI CLI Tools** step). Detection checks `~/.dotnet/dotnet`, `/usr/bin/dotnet`, `/usr/share/dotnet/dotnet`, and uses `bash -c` with `PATH` including `snap/bin` where needed.

Si pasas `--install-dotnet` o ya hay un SDK .NET detectado, el paso **Herramientas AI CLI** en la hoja de ruta y en el resumen final incluye una nota sobre **.NET**. También propone configurar la identidad de Git si aún no está definida. Al final de la instalación, si no se pasó `--manager`, el script preguntará interactivamente si se desea configurar la máquina como Manager de Docker Swarm.
