Major changes in 2.1

  • Devices and folders can now be grouped in the GUI by setting the new group attribute.

  • HTTP and HTTPS proxies with support for CONNECT can now be used, in addition to the existing support for SOCKS proxies (the environment variable all_proxy=https://...).

  • Block indexing can be turned off for folders where it's more desirable to optimise for reduced database size and overhead than minimal transfer size (the blockIndexing attribute on folder configuration).

  • GUI login session duration can be configured to be longer or shorter than the default one week, or set to infinitely long. The cookie path can also be adjusted. (The sessionCookieDurationS and sessionCookiePath attributes in the GUI configuration.)

This release is also available as:

  • APT repository: https://apt.syncthing.net/

  • Docker image: docker.io/syncthing/syncthing:2.1.3 or ghcr.io/syncthing/syncthing:2.1.3 ({docker,ghcr}.io/syncthing/syncthing:2 to follow just the major version)
