We have released beta 25 of Bun. This new release brings with it a whole host of improvements, most important of which is a new network transport that connects faster and more reliably - this means that your files will be backed up sooner and the backup status reflected earlier.
We also tweaked various internal settings to make the file scanning process faster and smoother. In addition, some small bugs have been fixed as well.
Beta 25 is available on automatic update, so you should be running it presently.
