Metered Plans Changelog

Version 1.5.2 - Released on 2026-05-12

Fix: Prevent latent infinite recursion in the main-site write-through path. The pre_update_option_{$key} filter callback write_through_to_main_site() called switch_to_blog(MAIN) and update_option(), which would re-fire the same filter and re-enter the method without a recursion guard — the symmetric counterpart of the 1.5.1 read-path bug. Adds the same two-part guard: short-circuit when already on the main site, and a per-option in-flight $resolving_write flag with try/finally.

Version 1.5.1 - Released on 2026-05-12

Fix: Prevent infinite recursion in main-site option override. The pre_option_{$key} filter callback override_with_main_site_option() called switch_to_blog(MAIN) and get_option(), which re-fired the same filter and re-entered the method without a recursion guard. On networks with many sites and many BerlinDB tables, this caused 89,000+ switch_to_blog events per subsite admin request, exhausting PHP memory and returning HTTP 500. The callback now short-circuits when already on the main site and uses an in-flight resolving guard for defence-in-depth.
