Xpart version 0.5.2

New feature:

• Introduced flags remove_underscored, remove_unused_space, remove_redundant_variables, keep_rng_state, keep_rng_state, compact in Particles.to_dict and Particles.to_pandas

Xpart version 0.5.1

Fix:

• Solves issue with unallocated slots in Particles.__init__, Particles.to_dict and Particles.from_dict.

Xpart version 0.5.0

New feature:

• Energy variables in Particles (delta, psigma, rvv, rpp) are now linked using xobjects.LinkedArray (e.g. part.delta[3] = 0.1 automatically updates also psigma, rvv, cpp)

Xpart version 0.4.0

New features:

• LocalParticle_add_to_energy can add to p_z only or to all momentum components (needed for synchrotron radiation)
• Added LocalParticle_generate_random_double and LocalParticle_generate_random_double to random number generator (needed for synchrotron radiation)

Xpart version 0.3.2

Fix:

• Include header files in pypi package

Xpart version 0.3.0

New features:

• Generation of halo and pencil distributions.
• Particles.to_dict creates by default a copy of the data on CPU.
• Introduced Particles.merge and Particles.filter methods.
• Introduced Particles.to_pandas and Particles.from_pandas methods.
• Introduced examples on how to save/load particles from/to file.
• build_particles and generate_matched_gaussian_bunch can find automatically the closed orbit and the one-turn matrix from a xtrack.Tracker object.
• Introduced explicit modes (set, shift, normalized_transverse) as input of the build_particles function.
• generate_longitudinal can use a xtrack.Tracker object to find the required machine parameters (RF voltage, harmonics, phases, momentum compaction factor).

Fix

• In the Particles.from_dict method all energy variables are taken from the dictionary (before they were all recomputed from delta)

Xpart version 0.2.0

Change in the Xsuite package structure:

• The xline package is removed
  • xline.Line becomes xtrack.Line
  • instead of xline.Drift, xline.Multipole etc. use directly xt.Drift, xt.Multipole
  • The Tracker objects are automatically updated when the line is modified (no need to regenerate the tracker)
• There is only one Particles class within Xsuite
  • xline.Partices and xtrack.Particles to be replaced by xpart.Particles
• The reference python implementation of the main elements, which used to be in xline, is moved to a small package called ducktrack, installed together with xtrack, to be used only for testing purposes (not part of normal tracking workflow)

New features

• Added build_particles function allowing to build a particles object from a reference particles plus arrays with geometric or normalized coordinates
• Added tools to compute and symplectify one-turn matrices (moved from pymask)
• Random number generator moved from xtrack togehter with the Particle class
• Ported PyHEADTAIL interface from xtrack
