What's New is an index, not a publisher: every entry below links to the vendor's own release notes, which are the authoritative source. Entries are labelled where they are hand-curated sample data, pre-releases, or drawn from a secondary source such as a developer blog.

##### 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.)
