when receiving a FCM push message for a channel the user is no longer in (this can happen when the disable command failed) an attempt will be made to explicitly unregister from the app server (which in turn will then send item-not-found on next push)
some nokia devices with Android 9 fail to start the service from the activity sometimes. since this is probably a race it should be save to ignore this
XMPP uris in the style of `xmpp:test@domain.tld?body=Something` can be used to
directly share a message with a specific contact. Previously the text was
always appended to the message currently in draft. The message was never send
automatically. Essentially those links where treated like normal text share
intents (for example when sharing a URL from the browser) but without the
contact selection.
There is a concern (CVE-2018-18467) that when this URI is invoked automatically
and the user is currently drafting a long message to that particular contact
the text could be inserted in the draft field (input box) without the user
noticing.
To circumvent that the text shared over XMPP uris that contain a particular
contact is now appended only if the draft box is currently empty.
Sharing text normally (**with** manual contact selection) is still treated the
same; meaning the shared text will be appended to the current draft. This is
intended behaviour to make the
'Hey I have this cool link here;' *open browser*, *share link* - secenario
work.
