Full Changelog: v0.60.0...v0.61.0

Xsuite version 0.60.0

Changes:

• Introduce capability to correct beam trajectory and closed orbit using response matrix (SVD or MICADO)
• Update optimizer API (e.g. Optimizer.enable(targets.., vary=...) instead of Optimizer.enable_vary() and Optimizer.enable_targets().
• Add hkick and vkick in Line table.
• Fix in XRotation.

Full Changelog: v0.57.2...v0.57.3

Xtrack version 0.57.2

Changes:

• Introduce Line.get_ibs_growth_rates(...)
• Introduce Line._insert_thick_elements_at_s(...)
• Replace _allow_backtrack with _allow_loss_refinement
• Add s_tol in element insertion methods.

Full Changelog: v0.57.1...v0.57.2

Xtrack version 0.57.1

Changes:

• Introduce new particles properties: kin_px, kin_py, kin_ps, kin_xprime, kin_yprime.
• Adapt tests (to avoid issue of cpymad)

Xtrack version 0.57.0

Changes:

• Introduce more compact json format (parameters equal to defaults are not stored)
• Slicing done with slice-elements referring to the parent. Parent element can be updated also after the slicing and slice elements are updated accordingly. As a result no expression is generated when slicing an element.
• Introduced Replica class to have multiple instances of the same element.
• Element lengths and magnet strengths correctly extracted for replicas and slices in Line.attr, Line.get_table() and Line.twiss().
• Introduced shift_x, shift_y and rot_s_rad properties to all elements in order to introduce misalignments.
• Introduced aperture associated to an element. If present, this is taken into account when slicing the element.
• TwissTable.reverse() reverses also the magnet strengths.
• More efficient and general survey (vertical bends are correctly handled).
• Rationalize element insertion (uses slicing capabilities).
• Removed only_markers flag in twiss.
• Removed element compounds (superseded by capabilities described above).
