A new release of libinput, 0.8, is available. This release contains a few of API/ABI breaks. You will likely need to update your code. Symbols deprecated since 0.6 were removed too. The soname was bumped to reflect the ABI changes.
Main changes: * Improved documentation. We have moved much of the wiki page into the doxygen system, the API docs now also explain higher-level concepts. * As usual, much of the effort went into improved touchpad support. For example, it is not necessary anymore to lift all fingers when switching from scrolling to pointer movement. * Scroll event types were merged. Previously we supplied horiz/vert scrolling as separate event, even in diagnonal scrolling. Now each scroll event may contain one or more axes. * Support for axis sources: a scroll event can be of source finger, wheel or continuous. This enables callers to implement kinetic ("fling") scrolling. * Scroll wheel events now return the data in degrees. A matching udev hwdb system is in place to adjust this when needed. A "discrete" scroll value is available if you're interested in the clicks only. * Left-handed configuration was renamed. For future tablet support, the button-based naming was inappropriate. A simple search/replace fixes this. API additions and changes: Userdata on a libinput context can now be changed after initialization: libinput_set_user_data() Scroll events have seen a revamp, with some features added and others changed in an API-incompatible way. The affected calls are: libinput_event_pointer_get_axis_source() libinput_event_pointer_has_axis() libinput_event_pointer_get_axis_value() libinput_event_pointer_get_axis_value_discrete() The source is one of finger, wheel or continuous (for button scrolling). Each event may now contain more than one axis, so you must check if the axis is available in an event. Retrieving a value for an unset axis is a bug. For wheel events, the returned value is now the angle in degrees. If you need wheel clicks instead, use the discrete value. Left-handed configuration has seen a rename. No actual changes but the rename requires API updates in callers. The new calls are: libinput_device_config_left_handed_is_available() libinput_device_config_left_handed_set() libinput_device_config_left_handed_get() libinput_device_config_left_handed_get_default() We have a few pending features that I decided not to merge for 0.8, expect 0.9 to follow very soon (most likely API/ABI compatible).
