Xtrack version 0.3.2

New features:

• Possibility to freeze a subset of particles coordinates during tracking
• pip installation works without -e

Xtrack version 0.3.0

New features:

• .copy method for Particles and BeamElement objects
• Generation of backtracking elements for basic elements
• Generation of backtracker from tracker
• Added new aperture shapes (LimitRectEllipse and LimitPolygon)
• Introduced LossLocationRefinement

Xtrack version 0.2.4

Bugfix:

• Memory leak in particles monitor

Xtrack version 0.2.3

Bugfix:

• Solved issue in Particles.set_particle

Added example:

• Direct check against SixTrack

Xtrack version 0.2.2

New feature

• Introduced random number generator accessible inside kernels

Xtrack version 0.2.1

New features:

• Use non-aligned objects in tracker instances, aligned objects elsewhere
• Use get_test_contexts from xobjects

Xtrack version 0.2.0

New features:

• Added BeamInteraction element to handle processes that produce secondary particles
• Removed num_particles attribute in from Particles class. Replaced with _capacity, _num_active_particles,_num_lost_particles. The last two are updated only on CPU while on gpu the information must be retrieved from Particles.state.

Other clean up and fixes are also included.

Xtrack version 0.1.2

Fix:

• Scale transverse momenta in LocalParticle_update_p0c

Xtrack Version 0.1.1

Fix:

• (zeta, delta) update in linear transfer matrix

Xtrack version 0.1.0

New features:

• Electron lens element has been introduced (thanks @phermes)
• Linear Transfer matrix element has been introduced (thanks @xbuffat).
• PyHEADTAIL interface has been improved to support slicing features (thanks @xbuffat)
• Multithreading via OpenMP is now fully supported (it can be enabled when creating the context, e.g. xo.ContextCpu(omp_num_threads=8). At the source code level the developer needs to use the annotation \\start_per_particle_block which introduces the necessary directives (see documentation).
• Particles coordinate names in xtrack, xline and xpart have been aligned. Now it is possible to create xtrack particles form xpart or xline particles simply by xtrackpart = xt.Particles(**xpartpart.to_dict()). The function xt.pyparticles_to_xtrack_dict has been removed.
