Syncthing 2.1.0 download

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:2.1.0 or ghcr.io/syncthing/syncthing:2.1.0
