Syngestures 2.0 is a major release and a rewrite of the core functionality. The daemon no longer has a runtime dependency on evtest (see #1) and now uses libevdev to obtain gesture events from the input device.
This change should make installing and using syngestures easier on all platforms (pre-compiled, statically linked binaries are available below).
Other changes include a significant improvement to performance and a decrease in resource consumption while interpreting events (i.e. while the touchpad is in use), from the already performant baseline of Syngestures 1.0. There have been quite a number of other improvements and changes, you can see the full changelog for reference. One notable improvement is to the sensitivity for gestures, which should be less finicky in this release.
Note that this has resulted in a change to installation instructions, in particular you need to make sure that your user account has the needed permissions to open the input device handle; usually this is as simple as adding your account to the input group (if it's not already a member). Otherwise, you would have to run syngestures as root, which we don't recommend!
