Transfer queueing
After transfer queueing was introduced, it frequently caused crashes or freezing when working with remote location. This problem was solved by introducing a waiting queue. To be released in Thunar 4.17.4.

This patch will not be backported. If you have this problem with Thunar 4.16, it is recommended to set parallel transfer to “Always” to avoid this problem.

You might ask about how it was done before. How can a job can be queued when there is no queue? The answer is simple. Since every transfer job runs on a separate thread, it is possible to play a game of musical chairs. Every thread tries to be the only active thread, and if a thread fails to start, it waits until the next opportunity arises. This is easy to implement when parallel transfer is already implemented. But unfortunately, the game did not go well.
WIP: Introduction of an execution safety flag
(I recommend reading Thunar !156 for the context.)
Since the executable bit is not enough to confirm that the file is safe to execute, I am implementing an additional metadata (execution safety flag). Thunar will check this flag even if the execution bit is on, so a user has to confirm that they know that they are launching an executable. This data is contained in GVFS-metadata, and will remember SHA-256 hash value of that file. This will work as a per-file option to allow launching the executable.
I already finished coding a feature to save a hash value per-file and using it to verify executable, and will be added to libxfce4util soon. Interface with this safety flag is still work-in-progress, though.
WIP: MTP freeze
Recently, there are a lot of issue reports about MTP, and most of the complaints are about freeze. A directory under mtp:// that contains a lot of files tends to cause problems. One problem is that icon renderer reads file contents and might clog the main event loop, so I am experimenting with icon rendering right now. Trying to change directory while a directory is loading also freezes the environment, so requesting a file list of the current directory (or cancelling it) might be blocking for some reason.
