 # Changelog
 
+## 2025-08-31 - 5.6.1 - fix(daemon)
+Ensure robust process shutdown and improve logs/subscriber diagnostics
+
+- Make ProcessWrapper.stop asynchronous and awaitable to avoid race conditions when stopping processes
+- Signal entire process groups on POSIX (kill by negative PID) and fall back to per-PID signalling; escalate to SIGKILL after a timeout
+- Await processWrapper.stop() from ProcessMonitor when enforcing memory limits or handling exits/errors to ensure child processes are cleaned up
+- Add logs:subscribers IPC endpoint and corresponding types to inspect current subscribers for a process log topic
+- Add optional CLI debug output in logs command (enabled via TSPM_DEBUG=true) to print subscriber counts and details
+- Support passing request.lines to getLogs handler in daemon to limit returned log entries
+
+## 2025-08-30 - 5.6.0 - feat(processmonitor)
+Add CPU monitoring and display CPU in process list
+
+- CLI: show a CPU column in the `tspm list` output (adds formatting and placeholder name display)
+- Daemon: ProcessMonitor now collects CPU usage for the process group in addition to memory
+- Daemon: ProcessMonitor exposes getLastCpuUsage() and ProcessManager syncs CPU values into IProcessInfo
+- Non-breaking: UI and internal stats enriched to surface CPU metrics for processes
+
+## 2025-08-30 - 5.5.0 - feat(logs)
+Improve logs streaming and backlog delivery; add CLI filters and ndjson output
+
+- CLI: add new logs options: --since, --stderr-only, --stdout-only and --ndjson; enhance streaming output and gap detection
+- CLI: fetch backlog conditionally (honoring --since) and print filtered results before live streaming
+- Client: add TspmIpcClient.requestLogsBacklogStream, onStream and onBacklogTopic helpers to receive backlog chunks and streams
+- Daemon: add logs:subscribe IPC handler to stream backlog entries to requesting client in small batches
+- Protocol: extend IPC types with LogsSubscribeRequest/Response and register 'logs:subscribe' method
+- Dependency: bump @push.rocks/smartipc to ^2.3.0 to support the streaming/IPC changes
+
 ## 2025-08-30 - 5.4.2 - fix(cli/process/logs)
 Reset log sequence on process restart to avoid false log gap warnings

+- `--lines <n>`           Number of lines to show (default: 50)
-- `--follow` - Stream logs in real-time (like `tail -f`)

+Notes:
+- Follow mode prints a small recent backlog, then streams older entries incrementally (to avoid large payloads) and continues with live logs.
+- Log sequences are restart-aware; TSPM detects run changes and keeps output consistent across restarts.

+#### Version check and service refresh
+
+Check CLI vs daemon versions and refresh the systemd service if they differ:
+
+```bash
+tspm -v
+# tspm CLI: 5.x.y
+# Daemon: running v5.x.z (pid 1234)
+# Version mismatch detected → optionally refresh the systemd service (equivalent to `tspm disable && tspm enable`).
+```
+This is helpful after upgrades where the system service still references an older CLI path.
+
 ### System Service Management
 
 Run TSPM as a system service (systemd) for production deployments.
