v2.4.42

[2.4.42] - 2026-05-07

Fixed

• Newspack_Performance_Aggregator\SettingsSync::maybe_queue_sync — fail-closed polarity now matches the file's documented intent and Newspack_Event_Aggregator\SettingsSync (class-settings-sync.php:113). Previously, missing or non-true enable_workers was not treated as "skip" — the test was isset && false === $config['enable_workers'], which let null/missing/empty count as "yes hub-mode" and silently fanned tuning settings (log_events, custom_events, etc.) out to remote spokes. The file's own comment ("Only hub nodes (enable_workers=true) should sync settings") was the canonical intent; the code was the bug. New test: SettingsSyncTest::test_maybe_queue_sync_skips_when_workers_unset. (newspack-performance-aggregator/includes/class-settings-sync.php)
