Changes in version 1.2.2                        

  - New function averageTrajectories() to average trajectories (or
    cycles)

                        Changes in version 1.2.1                        

  - When using trajectoryDistances with "cycles" objects the elements to
    be compared are cycles and dates are used for time comparison.
  - Bug correction in extractCycles() by N. Djeghri

                 Changes in version 1.2.0 (2025-11-11)                  

  - New functions trajectoryConvergencePlot() and cycleShiftArrows() by
    N. Djeghri
  - New functions trajectoryCorrespondence(), trajectoryRMA() and
    trajectoryRMAPlot() by N. Djeghri
  - Dependency from MannKendall package removed. Now the Mann-Kendall
    test is performed by calls to cor.test(method = "kendall")

                 Changes in version 1.1.1 (2025-08-28)                  

  - Trajectory subsetting according to time window limits
  - Bug correction in trajectory definition (missing surveys but
    existing times)
  - Bug correction in trajectory asymmetric tests (where done as
    symmetric previously)

                 Changes in version 1.1.0 (2025-05-05)                  

  - New functions is.metric() and is.synchronous().
  - Update of function trajectoryInternalVariation() (former
    trajectoryVariability()).
  - New function dynamicVariation().
  - New function variationDecomposition() for synchronous trajectories.
  - New function interpolateTrajectories() for interpolation to given
    times.
  - Function trajectoryConvergence() modified to allow a global
    convergence test (type = "multiple").

                 Changes in version 1.0.0 (2025-04-17)                  

  - Trajectory data structures have been introduced.
  - New functions for cyclical trajectory analysis (Djeghri et
    al, 2026).
  - New ETA metrics trajectoryVariability() and trajectorySpeeds().
  - Permutational test added for trajectoryDirectionality().
  - New function trajectoryMetrics() for evaluation of multiple metrics.
  - New function trajectoryWindowMetrics() for metrics evaluated over
    moving windows.
  - New function trajectoryShifts() to compare trajectories that are
    similar in shape but differ in speed.
  - New dissimilarity metric for trajectories, taking into account
    differences in time.

                        Changes in version 0.2.1                        

  - Update of function 'centerTrajectories' to add flexibility in
    trajectory centroid definition.
  - New vignette to illustrate centering.
  - Improvement of trajectoryProjection() to return relative position
    within selected segments, also when orthogonal projection does not
    exist.

                        Changes in version 0.2.0                        

  - New function 'smoothTrajectories' added.
  - Update of vignette 'Introduction to to Ecological Trajectory
    Analysis (ETA)'.
  - Correction of squared distances to centroid (GitHub issue #3).
  - EQA between individual states and dynamic envelopes (experimental).
