- A new room is now described completely at the moment it is created, because
that is the only moment the server accepts most of it: topic, a public
address people can type elsewhere, who may read the history, whom to invite
right away, whether only moderators may write, whether everyone invited
starts with the creator's rights, and whether the room stays on this server.
Encryption stays where it was, as the one decision that cannot be undone.
- A message that cannot be decrypted now says why. The reason was there all
along - the protocol library works it out and hands it over - and it was
being thrown away, so every case read the same. The one that matters is
"the sender did not share the key because they consider this device
insecure", which names a setting on the other side instead of leaving both
people guessing.
- Six dialogs were stuck in portrait on a device that is held sideways, among
them the warning about unverified recipients, which appeared rotated by
ninety degrees. They turn with the device now, and the short ones scroll so
their input field cannot end up behind the keyboard.
- Tapping a quote jumps to the message it quotes. That was never wired up at
all, and the same jump used by "show in conversation" for a pinned message
only ever worked when the message happened to be loaded already: it waited
for the row count to change, and a page of history that renders as nothing -
a stretch of membership changes does it - never changes that count. It now
retries on its own and says so when the message is beyond the loaded
history, instead of doing nothing at all.
- A picture can carry a caption, and an answer can carry a picture. Picking a
file used to send it on the spot, which made all three impossible at once:
no caption, no reply, and no way back after tapping the wrong thumbnail.
There is now a page between picking and sending that shows what is about to
go out, quotes the message being answered, and takes the caption. Both
belong there because neither can be added afterwards.
