# centerline 0.2.4 (2025-09-09)

UPDATES

• compatibility with ggplot2 4.0.0

centerline 0.2.3 (2025-03-19)

UPDATES

• updated the geomtextpath version to 0.1.5

centerline 0.2.2 (2025-03-16)

UPDATES

• the raybevel package is back on CRAN
• Added the explicit R>= 4.1.0 dependency

centerline 0.2.1 (2024-11-05)

UPDATES

• the raybevel package was removed from CRAN on October 22, 2024. It is not a core dependency, but it is crucial for some functions in the centerline pkg. To maintain raybevel::skeletonize accessibility for the cnt_skeleton function, raybevel is temporarily installed from GitHub.

centerline 0.2 (2024-10-01)

UPDATES

• geom_cnt_* function family for plotting centerlines with ggplot2

centerline 0.1.3 (2024-09-29)

UPDATES

• Switched from rlang to checkmate for type checks
• Web-only vignettes to reduce package size

centerline 0.1.2 (2024-09-28)

UPDATES

• Website launched with some vignettes.

centerline 0.1.1 (2024-09-27)

UPDATES

• Added a new argument to the cnt_skeleton() function — method. It should be either "voronoi" or "straight". Depending on it, the generating skeleton method will change.

centerline 0.1 (2024-09-24)

UPDATES

• CRAN first submission

centerline 0.0.5 (2024-09-23)

UPDATES

• Major refactoring of all core functions which led to a more stable results
• Test coverage increased

Bug fixes

• Fix #2
• Fix #5

centerline 0.0.4 (2024-09-13)

UPDATES

• Two times increase in centerline guessing due to a change in the search algorithm.
• Centerline guessing now occurs by calculating the longest path between skeleton nodes, rather than polygon nodes as it was previously. As a result, the final output is smoother at the edges.

Bug fixes

• Fix #1
• Fix #3

centerline 0.0.3 (2024-05-17)

UPDATES

• Got rid of the rmapshaper dependency. Similar performance achieved only with geos in the backend.
• Full geos support.
• More tests covering cnt_skeleton have been added.
• Transition from SpatVector to geos_geometry and vice versa now happens faster through the wk package, not through sf as before.

centerline 0.0.2 (2024-05-07)

UPDATES

• cnt_path_guess performs 1.25 times faster due to a wiser usage of the igraph and geos packages. The tidygraph dependency has been removed.
• Now, the cnt_path family returns one LINESTRING, not a collection of LINESTRINGS.

centerline 0.0.1 (2024-03-16)

NEW FEATURES

• New function added cnt_path_guess which returns the longest centerline based on polygon only

UPDATES

• Twofold speed increase by converting from terra objects to geos over wk package nor sf as it was earlier.
• Added ability to densify the input polygon through geos::geos_densify

centerline 0.0.0.9000 (2024-03-01)

NEW FEATURES

• Core functionality is added through the cnt_skeleton function
• Super easy routing is implemented with cnt_path function, which can be applied in cases with predefined starting and ending points
