  Magnetic reconnection in strongly magnetized (low-beta), weakly collisional
plasmas is investigated using a novel fluid-kinetic model [Zocco &
Schekochihin, Phys. Plasmas 18, 102309 (2011)] which retains non-isothermal
electron kinetics. It is shown that electron heating via Landau damping (linear
phase mixing) is the dominant dissipation mechanism. In time, electron heating
occurs after the peak of the reconnection rate; in space, it is concentrated
along the separatrices of the magnetic island. For sufficiently large systems,
the peak reconnection rate is $cE_{max}\approx 0.2v_AB_{y,0}$, where $v_A$ is
the Alfv\'en speed based on the reconnecting field $B_{y,0}$. The island
saturation width is the same as in MHD models except for small systems, when it
becomes comparable to the kinetic scales.
