wk 0.6.0

• Fixed wk_affine_rescale() to apply the translate and scale operations in the correct order (#94).
• Add wk_handle_slice() and wk_chunk_map_feature() to support a chunk + apply workflow when working with large vectors (#101, #107).
• C and R code was rewritten to avoid materializing ALTREP vectors (#103, #109).
• Added a wk_crs_proj_definition() generic for foreign CRS objects (#110, #112).
• Added wk_crs_longlat() helper to help promote authority-compliant CRS choices (#112).
• Added wk_is_geodesic(), wk_set_geodesic(), and argument geodesic in wkt() and wkb() as a flag for objects whose edges must be interpolated along a spherical/ellipsoidal trajectory (#112).
• Added sf::st_geometry() and sf::st_sfc() methods for wk geometry vectors for better integration with sf (#113, #114).
• Refactored well-known text parser to be more reusable and faster (#115, #104).
• Minor performance enhancement for is.na() and validate_wk_wkb() when called on a very long wkb() vector (#117).
• Fixed issue with validate_wk_wkb() and validate_wk_wkt(), which failed for most valid objects (#119).
• Added wk_envelope() and wk_envelope_handler() to compute feature-wise bounding boxes (#120, #122).
• Fixed headers and tests to pass on big endian systems (#105, #122).
• Incorporated the geodesic attribute into vctrs methods, data frame columns, and bbox/envelope calculation (#124, #125).
• Fix as_xy() for nested data frames and geodesic objects (#126, #128).
• Remove deprecated wkb_problems(), wkt_problems(), wkb_format(), and wkt_format() (#129).
• wk_plot() is now an S3 generic (#130).

wk 0.5.0

• Fixed bugs relating to the behaviour of wk classes as vectors (#64, #65, #67, #70).
• crc() objects are now correctly exported as polygons with a closed loop (#66, #70).
• Added wk_vertices() and wk_coords() to extract individual coordinate values from geometries with optional identifying information. For advanced users, the wk_vertex_filter() can be used as part of a pipeline to export coordinates as point geometries to another handler (#69, #71).
• Added wk_flatten() to extract geometries from collections. For advanced users, the wk_flatten_filter() can be used as part of a pipeline (#75, #78).
• options("max.print") is now respected by all vector classes (#72, #74).
• Moved implementation of plot methods from wkutils to wk to simplify the dependency structure of both packages (#80, #76).
• Added wk_polygon(), wk_linestring(), and wk_collection() to construct polygons, lines, and collections. For advanced users, wk_polygon_filter(), wk_linestring_filter(), and wk_collection_filter() can be used as part of a pipeline (#77, #84).
• Added a C-level transform struct that can be used to simplify the the common pattern of transforming coordinates. These structs can be created by other packages; however, the wk_trans_affine() and wk_trans_set() transforms are also built using this feature. These are run using the new wk_transform() function and power the new wk_set_z(), wk_set_m(), wk_drop_z(), wk_drop_m(), functions (#87, #88, #89).

wk 0.4.1

• Fix LTO and MacOS 3.6.2 check errors (#61).

wk 0.4.0

• Removed wksxp() in favour of improved sf::st_sfc() support (#21).
• Rewrite existing readers, writers, and handlers, using a new C API (#13).
• Use new C API in favour of header-only approach for all wk functions (#19, #22).
• Use cpp11 to manage safe use of callables that may longjmp from C++.
• Vector classes now propagate attr(, "crs"), and check that operations that involve more than one vector have compatable CRS objects as determined by wk_crs_equal().
• Added an R-level framework for other packages to implement wk readers and handlers: wk_handle(), wk_translate(), and wk_writer() (#37).
• Added a native reader and writer for sf::st_sfc() objects and implemented R-level generics for sfc, sfg, sf, and bbox objects (#28, #29, #38, #45).
• Implement crc() vector class to represent circles (#40).
• Added a 2D cartesian bounding box handler (wk_bbox()) (#42).
• Refactored unit tests reflecting use of the new API and for improved test coverage (#44, #45, #46).
• Added wk_meta(), wk_vector_meta(), and wk_count() to inspect properties of vectors (#53).
• Modified all internal handlers such that they work with vectors of unknown length (#54).

wk 0.3.4

• Fixed reference to wkutils::plot.wk_wksxp(), which no longer exists.

wk 0.3.3

• Fixed WKB import of ZM geometries that do not use EWKB.
• Added xy(), xyz(), xym() and xyzm() classes to efficiently store point geometries.
• Added the rct() vector class to efficiently store two-dimensional rectangles.
• Fixed the CRAN check failure caused by a circular dependency with the wkutils package.
• Added S3 methods to coerce sf objects to and from wkt(), wkb() and wksxp().

wk 0.3.2

• Fixed EWKB output for collections and multi-geometries that included SRID (#3).
• Fixed CRAN check errors related to exception handling on MacOS/R 3.6.2.

wk 0.3.1

• Added a NEWS.md file to track changes to the package.
