v3.1.0
- Correctly catch SIGHUP (when terminal closes, terminate DTail)
- Print connection stats every other second only if connection count has changed or when SIGUSR1 received.
- A first Ctrl+C now displays connection stats. A second Ctrl+C in a row terminates DTail.
- Removal of drun command (simplify dtail source code)
- Code refactoring, especially around regex handling
