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.
* 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:
Scroll events have seen a revamp, with some features added and others
changed in an API-incompatible way. The affected calls are:
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:
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).
