v0.16.0

0.16.0 (2026-08-27)

⚠ BREAKING CHANGES

• notify: notify.silence.windows may now list more than 5 entries when notify.slack.silence_button is off. Nothing that validated before stops validating — the bound is only relaxed, so no working deployment breaks on upgrade. What to watch for: a Matrix-only deployment that adopts a longer preset list will fail validation at startup if notify.slack.silence_button is later enabled. The error names notify.silence.windows and the flag; trim the list to between 2 and 5 entries, or leave the flag off.
