+## [0.8.11] - 2026-04-24
+
+### Fixed
+- `poshmcp build` now works correctly when run outside the PoshMcp repository directory. The embedded Dockerfile is now materialized to a temporary file before invoking docker, preventing "Dockerfile not found" errors.
+
+## [0.8.10] - 2026-04-24
+
+### Added
+- `--appsettings` option for `poshmcp build` command allows users to bundle a local `appsettings.json` file into their container image at build time, simplifying configuration management in containerized deployments.
+
+## [0.8.9] - 2026-04-24
+
+### Added
+- `examples/Dockerfile.user` now includes documented PSModule paths showing where PowerShell modules are available in the container (`/usr/local/share/powershell/Modules` for AllUsers, `/opt/microsoft/powershell/7/Modules` for built-in, `/home/appuser/.local/share/powershell/Modules` for CurrentUser).
+- Commented `COPY` directive examples in `Dockerfile.user` demonstrating how to easily copy local modules and startup scripts into the container.
