recipients need at least Android 5 to play the message; however
Conversations has been Android 5+ for a while now

Off by default

When replying to or mentioning a null-thread message, re-use the thread
id of any existing forked thread from a previous reply to that message
if there is one, so that not everyone replying to a null thread message
ends up generating a new thread when most of the time they mean to all
end up in the same new thread.

Of course user may tap thread icon at any time if they actually want a
second fork.

Mentions still do not generate a new thread since their association is
not tracked, but will follow the forked thread if it exists.

This switches the SQL based backup format to something JSON based.

The SQL based format has always been prone to SQL injections that, for example, could delete other messages or preexisting accounts in the app. This hasn’t been a concern this far because why would anyone purposely try to restore a faulty backup? However the argument has been made that a user can be socially engineered to restore an exploited backup file.
Before version 2.12.8 a third party app could even trigger the restore process, leaving the backup password entry dialog the only hurdle.
On top of that it has been demonstrated that a backup file can be crafted in a way that puts preexisting credentials into a 'pending' message to an attacker ultimately leading to that information being leaked.

While destorying information has always been deemed an acceptable risk, leaking information is one step too far.

Starting with Conversations 2.12.9 Conversations will no longer be able to read v1 backup files. This means if you are restoring on a new device and you have a v1 backup file you must first install Conversations <= 2.12.8, restore the backup, and then upgrade to Conversations >= 2.12.9.

ceb2txt¹ has support for v2 backup files. Conceivably ceb2txt could be extended to convert between v1 and v2 file formats. (ceb2txt already recreates the database from v1 files; It is relatively straight forward to create v2 files from that database. Pull requests welcome.)
