The wiki describes the tree after 6.3.3 as it lands on master: the settings store, the audit trail and alerts, what a domain does to a message, remote-domain policy, a backup that carries everything, and the rest of three batches
Twenty-seven pages, each written from the code at 3233b0cc4 and then checked sentence by sentence against it by a second reader: 166 claims verified, 23 corrected before this commit. Everything the tree holds that no release has is labelled as in the tree after 6.3.3 and not yet released, and the next release is called that rather than given a number.
The changes page carries the four schema steps 6042 to 6045 in section 2, the second and third batches in section 4e beside the first, the gate for 3233b0cc4 (2,410 tests, 2,402 passed, none failed, 8 skipped; the Linux figures are a placeholder until that run lands), and in section 5 the changes an upgrade makes with no switch - above all that the database is the settings store, that an edit to [Settings] in hMailServer.ini is undone at the next start and reported as HM5804, what to do instead, and that the password pepper stays in the file and out of every backup, so a restore onto new hardware needs it brought along. Fourteen pages that told a reader to edit the file now say how the same setting is changed once the store lands, and what an edit to the file does then; the settings reference says the table of INI keys is closed. The feature pages cover the backup that carries every per-account store, the audit trail and alerts with what each does not yet record or raise, syslog export, per-domain reports, remote-domain policy and mandatory TLS, SPF as RFC 7208, hmctl's configuration document, the tours, and the REST routes counted at the commit rather than guessed at.
The checking found things the tree itself gets wrong, which are recorded for the next batch rather than papered over here: hmctl's configuration document has an empty ini section because it reads a route that answers names only; the packaged Linux ini's RestApiPort=0 is adopted into the store at first start, so the packaging README's edit-the-file way of turning the REST listener on no longer works; the OpenAPI text for the ini routes and the note the server writes into hMailServer.ini still describe the file as the store; and five repository documents say what their wiki copies said before this commit.
