STRICT_R_HEADERS=1 (#222).wk_crs() and wk_set_crs() methods for bbox (#213)wkb() vectors (#196, #204).xy(NA, NA) is now read as a null feature instead of POINT EMPTY. This preserves the invariant that null features can also be identified using is.na() (#205).xy(NaN, NaN) is now read as POINT EMPTY and is.na(xy(NaN, NaN)) now returns FALSE. This means that both EMPTY and null points can roundtrip through xy() (#205).wk_meta() now contains a new column is_empty, which is TRUE for any feature that contains at least one non-empty coordinate. This allows more efficient detection of features with zero coordinates (#197, #199).sfc_writer() to correctly attach the classes attribute to sfc output with mixed geometry types (#195).sfc_writer() now has an argument promote_multi to write any input as the MULTI variant. This makes it more likely that an input vector will be read as a single geometry type (#198).wk_collection_filter() now correctly increments the part_id when calling the child handler (@brownag, #194).wkb_to_hex() (@anthonynorth, #183).vctrs::vec_proxy_equal() for wkb() vctrs (@anthonynorth, #183).sfc_writer(), which had returned NULL for some inputs (e.g., via wk_collection()) (@anthonynorth, #182, #186).wk_clockwise() and wk_counterclockwise() to re-wind polygon rings (@anthonynorth, #188).wk_coords<-() for in-place modification of coordinates (@mdsumner, #187).wk_trans_explicit() migrated from crs2crs (@mdsumner, #187).as.data.frame.default(), which no longer occurs in r-devel (#166).validate_wk_wkt() now errors for an object that does not inherit from ‘wk_wkt’ (#123, #146).wk_crs_projjson() to get a JSON representation of a CRS object. To make lookup possible based on shortcut-style CRS objects (e.g., "EPSG:4326" or 4326), added data objects wk_proj_crs_view and wk_proj_crs_json that contain cached versions of rendered PROJJSON based on the latest PROJ version (#147).wk_crs_proj_definition() method for wk_crs_inherit() (#136, #147).sfc_writer() for all wk classes, making conversions faster and fixing at least one issue with conversion of NA geometries to sf (#135).wk_plot() now plots NULL/NA geometries and mixed geometry types more reliably (#142, #143, #149).POINT Z EMPTY) (#141, #150).wk_polygon() doubled some points when the input contained closed rings (#134, #151).wk_count() exposed uninitialized values for empty input (#139, #153).xy_writer() now opportunistically avoids allocating vectors for Z or M values unless they are actually needed (#131, #154).wk_example() to access them and set various properties (#155).-Wstrict-prototypes (#157, #158).wk_chunk_map_feature() in favour of using chunking strategies directly (#132, #159).wk_coords() for xy() objects (#138, #160).rct_xmin(), rct_xmax(), rct_ymin(), rct_ymax(), rct_width(), rct_height(), crc_center(), crc_x(), crc_y(), crc_r(), xy_x(), xy_y(), xy_z(), and xy_m() (#144, #161).rct_intersects(), rct_contains(), and rct_intersection() (#161).wk_affine_rescale() to apply the translate and scale operations in the correct order (#94).wk_handle_slice() and wk_chunk_map_feature() to support a chunk + apply workflow when working with large vectors (#101, #107).wk_crs_proj_definition() generic for foreign CRS objects (#110, #112).wk_crs_longlat() helper to help promote authority-compliant CRS choices (#112).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).sf::st_geometry() and sf::st_sfc() methods for wk geometry vectors for better integration with sf (#113, #114).is.na() and validate_wk_wkb() when called on a very long wkb() vector (#117).validate_wk_wkb() and validate_wk_wkt(), which failed for most valid objects (#119).wk_envelope() and wk_envelope_handler() to compute feature-wise bounding boxes (#120, #122).as_xy() for nested data frames and geodesic objects (#126, #128).wkb_problems(), wkt_problems(), wkb_format(), and wkt_format() (#129).wk_plot() is now an S3 generic (#130).crc() objects are now correctly exported as polygons with a closed loop (#66, #70).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).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).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).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).wksxp() in favour of improved sf::st_sfc() support (#21).attr(, "crs"), and check that operations that involve more than one vector have compatable CRS objects as determined by wk_crs_equal().wk_handle(), wk_translate(), and wk_writer() (#37).sf::st_sfc() objects and implemented R-level generics for sfc, sfg, sf, and bbox objects (#28, #29, #38, #45).crc() vector class to represent circles (#40).wk_bbox()) (#42).wk_meta(), wk_vector_meta(), and wk_count() to inspect properties of vectors (#53).xy(), xyz(), xym() and xyzm() classes to efficiently store point geometries.rct() vector class to efficiently store two-dimensional rectangles.wkt(), wkb() and wksxp().
