The wait it over - Sync 3.0 is now available!

Yes! - See the announcement of Sync 3.0 thread.

.!sync files are temporary files created whilst data is being received. They are safe to delete, however, if they relate to a file currently in the process of being received, that file will begin transfer again from the start.

Please check the date/time is correct on your device and on all other connected devices in your mesh.

There actually exists portable versions of Sync - however, this feature was officially dropped some time ago as of Sync 1.2.82 (although continued to work for early 1.3.x builds too)... so if you can find one of those builds, you can run Sync portable. Otherwise, this thread is certainly the right place to request that portability be brought back

If you go to "My Devices", and select one of your connected peers, Sync will display the version of Sync running on that device (along with its IP and MAC addresses)

The changelog has now been updated to 2.5.9. There are only minor cosmetic changes in this update.

You may like to check out Resilio Connect which offers centralized management of permissions/shares. I suspect these Connect-specific "Enterprise" options won't be back-ported into Sync Business

Sounds more like it may potentially be a bug. I've moved this to the troubleshooting forum, but you may also wish to open a support ticket.

As the conf file is essentially a JSON file, each line in a section (apart from the last) needs to end with a comma.

There is - you can enable debug logging. Do be aware though that Sync can't sync files that are open/locked/in-use by other applications - which may be the reason why some of your files are not immediately syncing

The "folder_rescan_interval" advanced setting can be used to set a recurring interval at which your folders are re-scanned for changes. If changes are not being picked up automatically, this regular re-scanning setting should pick them up.

The team are aware of this issue and are working on a resolution - please see this post.

Have you tried unticking the "Show notifications" option (Settings -> General), and changing the advanced Power User setting "enable_file_system_notifications" to false?

Don't worry - 2.5 will come to auto-update in due course. New builds are always announced here on the forums in the first instance and initially only available for manual install/update. The main reason auto-update isn't usually enabled at the same time as a new build is announced here, is to allow the team to capture any significant issues from the sub-set of users who manually update, that perhaps weren't picked up in testing/QA phase, before pushing a new version out to everyone. Typically it can be anywhere from a few days to a few weeks before auto-update is enabled.
