GPU:

• 1Dcartesian geometry now available.
• Compilation simplified and better documented.
• Improved performance of particle sorting.

Features:

• Relativistic field initialization now supports multiple species and both direction propagations.
• Added the argument phase_offset in laser definitions such as LaserGaussian2D.
• The LaserGaussianAM definition will only use one coordinate for its focus argument
  (the transverse coordinate of the focus in this geometry is zero).
• Small improvements in PML for envelope model (AM and 2D).
• Deprecated smilei_rand_max.
• New namelist variables smilei_omp_threads and smilei_total_cores.

Happi:

• In Scalar, it is now possible to make an operation on scalars such as "Uelm+Ukin".
• The list of available scalars can be obtained from getScalars().
• New arguments xoffset and yoffset to shift plot coordinates.
• New argument timestep_indices as an alternative to timesteps.
• Changed coordinate reference for 2D probe in 3D or AM geometry
  (zero is the box origin projected orthogonally on the probe plane).

Documentation:

• Dark theme (click the switch on the bottom left, or set browser preferences).

Bug fixes :

• dump_minutes often failed to write some checkpoint files.
• "auto" limits in ParticleBinning could fail with only one side on "auto".
• CFL condition is more accurately determined in AMcylindrical and the feature timestep_over_CFL should be more reliable in that geometry.
