mod_muc_moderation: Copy XEP-0421 occupant-id from retracted message Lets clients correlate the sender of whatever was retracted by moderators. Behavior limited to Prosody 0.12, otherwise there are no assurances of the origin of the occupant-id tag. Ref #1816

mod_muc_block_pm: Advertise that Moderators are allowed to send PMs But there appears to be no way in XEP-0045 to advertise that Anyone can send PMs *to* Moderators.

mod_muc_block_pm: Allow private messages to yourself No harm in it. Beagle apparently uses it for XEP-0333 in public channels

mod_http_oauth2: Show errors on device flow user code entry page If the user enters the code incorrectly, having to click back to try again is no fun. Instead, show the error and the code entry form again.

mod_http_oauth2: Namespace the various codes to minimize confusion Both for the programmer and in OAuth flows. While unlikely, it should not be possible to cause weirdness e.g. by typing a client id and authorization code into the device code entry.

mod_default_bookmarks: Include 'autojoin' in examples The text does mention this, but who reads that?

mod_http_oauth2: Improve a description in schema

editorconfig: Document established conventions

mod_muc_limits: Drop unsupported Prosody versions from Compatibility table

mod_muc_limits: Set syntax of config snippets to enable syntax highlighting
