  • The post states the fix is already released in v0.11.5, but v0.11.5 does not appear to be released/tagged yet (latest tag is v0.11.4). This reads as a completed release rather than an upcoming one, which can mislead readers.
Fix released in Errbit version: v0.11.5.

  • The suggested workaround relies on the email client sanitizing HTML, which isn't a reliable mitigation and doesn't help self-hosters who need an immediate server-side fix. Consider pointing to a concrete workaround (apply the patch from the linked PR / replace the affected template line) or disabling comment notification emails until upgrading.
Workaround: Make sure that you are using an email client that properly
sanitizes the HTML body of the email.
