Xtrack version 0.26.5

Changes:

• Fix: allow Line.insert_element to replace Marker elements.

Xtrack version 0.26.4

Changes:

• Fix in loss location refinement: backtracking through Marker elements allowed by default.

Xtrack version 0.26.3

Changes:

• Fix segfault in multi-foam monitor when at_turn is negative.
• Set at_turn negative in twiss to avoid writing in installed monitors.

Full Changelog: v0.26.2...v0.26.3

Xtrack version 0.26.2

Changes:

• Fix issue with tracking timing on GPU
• Added example measuring tracking time on GPU

Xtrack version 0.26.1

Changes:

• Explicitly specified tolerances and steps in tests for Tracker.match (was inducing test failures on certain machines)

Xtrack version 0.26.0

Changes:

• Improve Tracker.match: introduce "BFGS" optimizer used when number of knobs is different from the number of targets. Introduced possibility to specify tolerances on the targets and steps for the knobs.
• Introduce test with c_minus matching.
• Introduce TwissTable.get_normalized_coordinates(...).
• Introduce new elements XRotation and YRotation.
• Fix issue with Tracker.twiss(at_s=...) in the presence of synchrotron radiation.
• Fix in "Elens" (missing /*gpuglmem*/ on one pointer).
• Optimization in tapering code.
• Change method for marker insertion in twiss(at_s=...)
• Update in tests: different contexts are checked using decorator from xobjects.

Xtrack version 0.25.0

Changes:

• Possibility to use prebuilt kernels instead of compiling just in time.
• In tracker.compensate_radiation_energy_loss added record_iterations flag.
• Added Marker element type and modified mad loader to use markers instead of zero-length drifts.
• In line optimizers, added possibility of preserving all markers or selected ones.
• Added Line.from_sequence constructor.
• Added some missing backtracking elements.
• Added "exact" drift mode.

Xtrack version 0.23.5

Changes

• Tracker.twiss can find closed orbit for a given z0 coordinate
• Tracker.twiss computes Mais-Ripken coupled beta function and c-minus coupling coefficient.
• Tapering correctly handles cavities with zero voltage.
• Changed default parameters for aperture elements.
• Add granular flaky_assertions contexts to flaky tests.
• Fix wrong memory space for pointer in tracker, resulting in compile error on AMD and Intel OpenCL contexts.

Full Changelog: v0.23.4...v0.23.5

Xtrack version 0.23.4

Changes:

• Add beamstrahlung option to configure_radiation

Full Changelog: v0.23.3...v0.23.4

Xtrack version 0.23.3

Changes:

• Introduce Tracker.optimize_for_tracking method, that performs line rationalisation to maximise tracking speed
• Introduce timing of the track session in Tracker.track
