Release 6.4.3

Shopclass 6.4.3

This release fixes security issues in the admin plugins screen, listing editing, password reset
e-mails on some Docker setups, redirects and sign-in forms. New hourly spam limits can be set in
Settings → Spam and bots. Sites updating from 6.3 now finish the update when PHP's cache does not
re-check files.
