Changes in version 0.1.10                        

  - Corrected bugs in analyseLP() (in LPfuncs.R) and analyseHP() (in
    HPfuncs.R) that caused crashes when testing for CP or BT points.
    Erroneously, the Jacobian matrix of the model function was computed,
    while it should have been the Jacobian of the extended system

  - Corrected bugs in assigning names to the elements of the tangent
    vector in analyseLP() (in LPfuncs.R) and analyseHP() (in HPfuncs.R)

                 Changes in version 0.1.9 (2025-02-15)                  

  - Corrected a bug in bifpar1plot.R resulting in dashed lines being
    used to draw curves of stable equilibria

  - Corrected a bug in bifpar1plot.R that labelled bifurcation points
    wrongly in 3D plots if some bifurcation points were off-scale

                 Changes in version 0.1.8 (2023-12-04)                  

  - Corrected the checking whether variables had gone of scale during
    limit cycle continuation

  - Updated the DESCRIPTION file as some of the required packages (e.g.
    shiny) are no longer available for the earlier R versions

  - Built-in protection in bif1parplot.R against absence of "eigvals"
    from the curve list

  - Introduced a function deBifReset() to reload the package in case of
    computational problems

  - Implemented a routine that computes the multipliers of a limit
    cycle, relying on the built-in function solve() to solve for the
    inverse of a matrix and for the generalized eigenvalues. These
    multipliers are subsequently used to plot the limit cycle either
    with a solid line in case it is stable or with a dashed line when
    unstable

                 Changes in version 0.1.7 (2023-01-18)                  

  - Changed the use of the function sprintf() to snprintf() in the
    underlying C code as sprintf() has been deprecated in macOS 13

  - Corrected a bug (superfluous checking of the value of 'ycol' in case
    length(state) == 1) in phaseServerFuncs.R that prevented the
    preventing of all steady states

  - Corrected a missing value TRUE/FALSE error that occurred when
    phaseplane() was started for a 1-dimensional model for the very
    first time

  - Corrected a bug in phasePlot2D.R that generated an error when
    selecting a variable with index > 2 in a model with more than 2
    variables

  - Added an argument 'verify_fa = FALSE' to various calls to
    shiny::icon() in phaseUI.R and bifUI.R to prevent error messages
    from the FontAwesome package

                        Changes in version 0.1.6                        

  - Introduced a new numerical option "Initial step size" to control the
    initial step along a solution curve

  - Changed the default grid dimension in the Portrait tab of
    phaseplane() to 8 and allowed this setting to be varied between 3
    and 20

  - Reduced the font sizes in the menus of both phaseplane() and
    bifurcation()

                 Changes in version 0.1.5 (2022-04-08)                  

  - Changed the calls to the Lapack routines dgetrf, dgecon and dgesvx
    to correctly pass string from C to Fortran following ‘Writing R
    Extensions’ §6.6.1

  - Changed computation of derivatives in phaseplane() to solve problems
    with derivative functions that are not vectorizable. Derivatives are
    now only calculated when either parameter change or the plot options
    change.

  - Stricter checking of input curves in bifurcation() and phaseplane()
    to prevent crashes when the parameter list has been changed

  - Show steady state details in phaseplane for all tabs >= 3 and
    improved the checking on the steady state solutions in phaseplane()

  - Corrected bug in 3D plotting of bifurcation graph that resulted in
    wrong axis labeling

  - First point localisation in 2 parameter plot automatically swaps
    variables if unsuccessful

  - Bugs solved for full report of computations

  - Removed the on.exit() call at the start of bifurcation(), which
    generated a warning about the absence of a graphic context

  - Changed the on-exit() calls in phaseplane to correctly plot the
    steady state points

  - Wrapped the call to deSolve time integration method into tryCatch()
    to catch errors occurring during the time integration

                 Changes in version 0.1.0 (2022-03-14)                  

  - First official version to be submitted to CRAN. The intensive
    computational parts (solving for solution points, solving for limit
    cycles) are now carried out by C-code. The package has been tested
    intensively by a group of BSc students during a 4-day class

                        Changes in version 0.0.5                        

  - Compared the computation of the limit cycle condition and the
    jacobian of the limit cycle condition with the same computations in
    Matcont. The jacobian and the limit cycle condition differ less
    than 1.0E-5 from each other, showing the correctness of the code
