wk 0.9.2

• Add wk_crs() and wk_set_crs() methods for bbox (#213)
• Fix wk_trans inconsistent meta flags handling (#217)
• Ensure package builds on arm64 for Windows (#220)

wk 0.9.1

• Fix format strings/arguments for R-devel (#209).

wk 0.9.0

Breaking changes

• The common well-known binary representation of POINT EMPTY (i.e.,
  POINT (nan nan)) is now handled as POINT EMPTY allowing empty points
  to roundtrip through 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).

Bugfixes and improvements

• 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).
• Updated PROJ data to use the latest pull of the database packaged with
  PROJ 9.3.0 (#201).
• The wk package now compiles once again on gcc 4.8 (#203, #206).
• Fixed sfc_writer() to correctly attach the classes attribute to
  sfc output with mixed geometry types (#195).
• Function 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).
• The wk_collection_filter() now correctly increments the part_id when
  calling the child handler (@brownag, #194).

wk 0.8.0

• Added wkb_to_hex() (@anthonynorth, #183).
• Implemented vctrs::vec_proxy_equal() for wkb() vctrs
  (@anthonynorth, #183).
• Fixed sfc_writer(), which had returned NULL for some inputs
  (e.g., via wk_collection()) (@anthonynorth, #182, #186).
• Added wk_clockwise() and wk_counterclockwise() to re-wind polygon rings
  (@anthonynorth, #188).
• New replacement-function mode for wk_coords<-() for in-place modification
  of coordinates (@mdsumner, #187).
• New function wk_trans_explicit() migrated from crs2crs (@mdsumner, #187).

wk 0.7.3

• Fix tests for updated waldo package (#178).

wk 0.7.2

• Fix use-after-free warnings.

wk 0.7.1

• Fix implicit reliance on error as.data.frame.default(),
  which no longer occurs in r-devel (#166).

wk 0.7.0

• Remove legacy headers that are no longer used by any downstream package
  (#146).
• validate_wk_wkt() now errors for an object that does not inherit from
  'wk_wkt' (#123, #146).
• Added 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).
• Added a wk_crs_proj_definition() method for wk_crs_inherit() (#136,
  #147).
• Conversion to sf now uses the 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).
• Exported EMPTY geometries to well-known text now include dimension
  (e.g., POINT Z EMPTY) (#141, #150).
• Fixed bug where wk_polygon() doubled some points when the input contained
  closed rings (#134, #151).
• Fixed bug where wk_count() exposed uninitialized values for empty input
  (#139, #153).
• The xy_writer() now opportunistically avoids allocating vectors for Z
  or M values unless they are actually needed (#131, #154).
• Added example WKT for all geometry types and dimensions plus helper
  wk_example() to access them and set various properties (#155).
• Fixes warnings when compiling with -Wstrict-prototypes (#157, #158).
• Removed wk_chunk_map_feature() in favour of using chunking strategies
  directly (#132, #159).
• Optimized wk_coords() for xy() objects (#138, #160).
• Added accessor methods for record-style vectors: 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).
• Added rectangle operators rct_intersects(), rct_contains(),
  and rct_intersection() (#161).

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).
