util.sasl.scram: Mention if clients try PLUS without channel binding This isn't normal, but is it invalid? Likely a client bug in any case.

mod_mam: Store only incoming errors Unclear if clients normally ever send error messages, but there may be locally generated bounces sent on behalf of local sessions.

mod_csi_simple: Explicitly mention iq stanzas Should be more obvious that all iq stanzas are considered important. Changes behavior for invalid things in the default namespace.

mod_csi_simple: Clarify what might not be stanzas here

mod_csi_simple: Consider nonzas important This case was previously handled by fall-trough at the end of the function.

mod_csi_simple: Explicitly consider errors important This was already the case for presence and iq stanzas but not messages.

mod_register_limits: Fix text reason field name for 'throttled' Copy-paste mistake presumably

mod_register_ibr: Fix reporting of registration rejection reason When the reason is reported as an util.error object the `reason` field is empty and the reason text should be extacted from the error object.

mod_register_limits: Fix typo error name (fix #1539 p2) (thanks Ge0rG) Probably because autocomplete.

mod_register_limits: Fix order of arguments to util.error (fix #1539 p1) (thanks Ge0rG)
