Software Update: Syncthing 1.8.0

Version 1.8.0 of Syncthing has been released. Syncthing is an open source program that allows files to be synchronized between two computers. This happens just like with BitTorrent Sync without a central server in between, as is the case with storage services such as Dropbox, Google Drive, OneDrive and iCloud. The software is available for Windows, Linux, macOS and Android, among others. There are also packages for Synology and Qnap. The following changes and improvements have been made in this release:

This release:

  • Adds the experimental copyRangeMethod config on folders, for use on filesystems with copy-on-write support. please see for details.
  • Adds TCP hole punching, used to establish high performance TCP connections in certain NAT scenarios where only relay or QUIC connections could be used previously.
  • Adds a configuration to file versioning for how often to run cleanup. This defaults to once an hour, but is configurable from very frequently to never.

Bug fixes:

  • #5425: Allow editing ignore patterns texterea in GUI’s folder dialog even when #include fails
  • #6733: strelaysrv can’t propely unmarshall a response when joining a pool
