Deluge BitTorrent Client 2.0 Released With Sequential Downloads, Now Uses Python3 And Gtk3

Deluge BitTorrent client has reached version 2.0 stable recently, after more than 2 years since the previous stable release. The new stable Deluge version comes with major changes, including code ported to Python 3, Gtk UI ported to Gtk 2, sequential downloads support, a new logo, and much more.

Deluge is a free and open source BitTorrent client that runs on Linux, Windows, macOS and *BSD. It's written in Python, and it includes a text console, a web interface, and a graphical desktop interface that uses Gtk.

The application uses a client / server (daemon) model, and features:

Allows connecting remotely to the Deluge daemon
BitTorrent Protocol Encryption
UPnP, DHT, NAT-PMP, LSD and Peer Exchange support
Proxy support
Private Torrents
Global and per-torrent speed limits
Configurable bandwidth scheduler
Password protection
Magnet links
A plugin system

Deluge ships with a few built-in plugins, including a plugin to automatically adding torrent files from a monitored folder, blocklists, execute commands on events, auto extract files on completion, scheduler, and more.

There are also quite a few third-party plugins available, which extend its functionality, like auto shutdown, batch renamer, smart move, RSS plugins, and many others.

Blocklist Plugin: Implemented whitelist support to both core and Gtk UI

Two minor versions (2.0.1 and 2.0.2) were released shortly after the Deluge 2.0 release, to fix a few minor issues.

It should be noted that Deluge 2.0 is not compatible with Deluge 1.x (both clients and daemons). Also, 3rd party plugins may need to be updated to work with the latest Deluge 2.0 series.
