Hi all,

I'm pleased to announce the release of stalld v1.27.1, now available
at kernel.org, GitLab, and GitHub.

Overview

This release includes two behavior changes to improve usability and
error handling, along with extensive test infrastructure improvements.

Behavior Changes

Syslog Logging Now Opt-In (Wander Lairson Costa)
- Syslog output is now disabled by default
- Use -s/--log_syslog to enable syslog logging
- systemd service file updated to preserve existing behavior
- Prevents unwanted syslog traffic when using verbose mode

Exit on Invalid CPU Affinity (Wander Lairson Costa)
- stalld now exits with an error on invalid -a/--affinity arguments
- Previously invalid affinity settings were silently ignored

Test Infrastructure (33 commits)

- Added event-driven helpers replacing fixed sleep delays
- New pass()/fail() functions for consistent reporting
- Improved test reliability and maintainability
- Fixed various test bugs and path issues

Upgrade Notes

If you run stalld manually (not via systemd) and rely on syslog
logging, add the -s flag to your command line. The systemd service
file already includes this flag.
