v3.9.0

Added

• Mailing lists, unsubscribing and bulk sweeps. mailingLists (and fastmail lists) groups every email carrying List-Unsubscribe by sender, with counts, unread counts and the newest unsubscribe links; unsubscribe (and fastmail unsubscribe) leaves a list by RFC 8058 one-click POST, restricted to public HTTPS addresses with no redirects, or by its mailto: address, PREVIEW then CONFIRM; Email.unsubscribe parses the headers on any email; sweepEmails moves, marks read or marks spam everything a filter matches; markAsNotSpam (and fastmail not-spam) undoes a spam verdict. Spam verdicts now set $junk/$notjunk as well as moving the email. Fastmail's filter rules are not reachable over JMAP, so they are not managed here.

Internal

• Builds use the latest stable Rust. mise installs rust at latest.
