Changes in version 1.0.3 (2014-12-02)

New features or changed behaviour of old functions

    o   read.linearmask() allows for multiple Line objects within each
    Lines object of a SpatialLinesDataFrame

    o   subset.linearmask() acquires argument droplinesbeyond for
    cleaning the SLDF attribute

    o   snapPointsToLinearMask() now snaps to the vertices of the graph
    attribute, rather than trying to use the maptools function snapPointsToLines()

    o   showpath() also returns mask coordinates along each selected path

    o   checkmoves() new utility function for detecting extreme moves

    o   plot.linearmask() now uses plot.mask allowing a wider range of options

Other

    o   first CRAN release

    o   addedge and deleteedge renamed addedges and deleteedges

    o   vignette considers breaks in graph and new secr function 'checkmoves'


Changes in version 1.0.1 (2014-11-02)

New features or changed behaviour of old functions

    o   read.linearmask will read directly from a polyline shapefile

    o   interpoint distances within a line are coerced to the correct spacing value
        (no longer simple Euclidean distances) 

    o   direct and precise algorithm for placing mask points along lines (no longer calls spsample) 

    o   edge editing functions redefined; function showedges() replaces showskips()

    o   make.line() enhanced (randomstart, endbuffer, clusters, multiline masks etc.)

    o   new function cleanskips() removes superfluous joins (automatic in read.linearmask)

Bugs fixed

    o   none yet

Other

    o   now 'Depends' on igraph package (always loaded)

    o   no longer exports alongmask() (use make.line())
