+# Patchloom for VS Code
+
+This release aligns the extension with [Patchloom CLI v0.7.0](https://github.com/patchloom/patchloom/releases/tag/patchloom-v0.7.0) and completes platform parity for the managed installer.
+
+## Aligned with Patchloom CLI v0.7.0
+
+v0.7.0 renamed CLI arguments to match what LLMs naturally generate. The extension's Quick Action **Replace text** now uses the v0.7.0 syntax (`patchloom replace <old> --new <new> <file>`), and the MCP e2e test suite is updated for the `selector` to `key` parameter rename in doc tools.
+
+If you use the Replace quick action, update the CLI to v0.7.0+ before upgrading the extension.
+
+## Full platform parity for managed install
+
+The managed installer now covers all 8 targets shipped by the CLI. Three new platforms added in this release:
+
+| Target | Use case |
+|--------|----------|
+| `aarch64-pc-windows-msvc` | Windows ARM64 (Surface Pro X, Snapdragon laptops) |
+| `x86_64-unknown-linux-musl` | Alpine dev containers, musl-based CI runners |
+| `aarch64-unknown-linux-musl` | Alpine ARM64 dev containers |
+
+Musl detection is automatic: the extension checks for `/lib/ld-musl-<arch>.so.1` and downloads the correct binary. No configuration needed.
+
+## Install or update the CLI
+
+```bash
+brew upgrade patchloom                  # Homebrew
+cargo install patchloom                 # from source
+```
+
+Or run **Patchloom: Update Patchloom** from the VS Code command palette if you use the managed installer.
