+First **development** release: the proxy is usable end-to-end for TCP, managed local stubs, and **remote Linux targets** over SSH. Pre-release semver (`-dev.N`) signals API and CLI may still evolve before **0.2.0**.

+- **`transport = remote_ssh`**: run `gdbserver` on a remote host via OpenSSH; optional **`upload_local` / `upload_remote`** to **`scp`** the ELF before connect; optional **`RSGDB_SSH_PASSWORD`** + **`sshpass`** for non-interactive password auth.
+- **Example** [`examples/board_test_app/`](examples/board_test_app/README.md): tiny aarch64 Linux smoke binary, [`rsgdb.remote.toml`](examples/board_test_app/rsgdb.remote.toml), [`install_ssh_key.sh`](examples/board_test_app/install_ssh_key.sh), [`debug_remote.sh`](examples/board_test_app/debug_remote.sh) (SSH key preflight + GDB batch smoke).
+- **Design principles** (README): ease, automation, reliability for embedded remote debugging.
+- **Documentation**: Linux target SSH setup, CONTRIBUTING cross-links, config examples for `remote_ssh`.

+### Changed
 
-## [0.1.0] - 2026-03-27
+- **Configuration** (`[backend.remote_ssh]`, validation): user, optional host override, SSH port, identity, upload paths, gdbserver argv with `{port}` placeholder.
+- **Proxy**: backend connect path supports remote SSH session lifecycle alongside TCP and native spawn.
 
-### Added
-- Initial release
-- Project foundation and structure
+### Notes

+- **Stability**: Suitable for daily development and field trials; treat semver pre-releases as **unstable** for automation that pins exact versions.
+- **Validation**: `./scripts/validate_local.sh` matches CI (fmt, `cargo test --all-features`, clippy `-D warnings`, `cargo doc`).

 This runs **`cargo tree -d`** (duplicate transitive versions — often benign, e.g. `thiserror` v1 via `svd-parser` and v2 via `tracing-appender`), **`cargo audit`** against [RustSec](https://github.com/RustSec/advisory-db) (install: `cargo install cargo-audit`), and **`cargo outdated --workspace`** if `cargo-outdated` is installed (`cargo install cargo-outdated`).
