+## [2.1.1] - 2026-04-17
+
+### Fixed
+- **bssh-server panic on client connection**: `new_client_with_addr` called `block_on()` inside the tokio async runtime to check the auth rate limiter ban list, causing an immediate "Cannot start a runtime from within a runtime" panic on every incoming connection. Added non-blocking `AuthRateLimiter::try_is_banned()` using `RwLock::try_read()`. (#185)
+- **bssh-server auth rejection after successful verification**: All `SshHandler` constructors created a local `SessionInfo` that was never registered with `SessionManager`. After public key or password verification succeeded, `authenticate_session()` returned `SessionNotFound`, rejecting the client. Fixed by deferring session creation to the authentication flow via `SessionManager::create_session()`. (#185)
+
+### Changed
+- Improved Launchpad PPA packaging for Rust 2024 edition: updated `debian/rules` variants, added `debian/sanitize-vendor.py` for vendored crate checksum sanitization, fixed hidden path handling
+- Added `.pyc` files to `.gitignore`
