s2 1.1.2

• Fixed test for as.data.frame() for s2_cell() to comply with new wk
  version and the latest release of R (#207).
• Fix unary union of an empty multipolygon (#208).
• Added #include <cstdint> to an Abseil header to fix compilation with
  gcc13 (#209, #210).
• Update internal Abseil to 20220623.1 LTS (#213).

s2 1.1.1

• Fix new CRAN check warnings (#202, #203).

s2 1.1.0

• Fix for s2 build on Windows with R <= 3.6.x (#142)
• Fix for s2 build on MacOS with multiple openssl versions (#142, #145, #146)
• Fix for s2 build on 32-bit openssl (#143, #147)
• Added s2_convex_hull() and s2_convex_hull_agg() (@spiry34, #150,
  #151, #163).
• Added max_distance argument to s2_closest_edges(), making
  distance-constrained k-nearest neighbours possible (#125, #156, #162).
• Added a spherical s2_point_on_surface() implementation for polygons
  (@kylebutts, #152, #161)
• Added a s2_cell_union() vector class to represent cell coverings and
  operators to generate them from an s2 geography vector (e.g.,
  s2_covering_cell_ids()). Cell unions are useful as compact representations
  of spherical geometry and can be used like a bounding box to determine
  a possible intersection with one or more geographies (#85, #94, #164).
• Refactored the simple features compatability layer into a standalone
  code base for potential future use in a Python adaptation (#165).
• Migrate input and output to non-deprecated wk package handlers and writers
  (#101, #165, #168).
• Make s2_union_agg() more efficient using a recursive merge strategy
  (#103, #165).
• Fix package build on Raspberry Pi (#169, #171).
• Fix warning on clang14 when compiling with -O0 (#167, #172).
• Added s2_prepared_dwithin() and fixed s2_dwithin_matrix() such that it
  efficiently uses the index (#157, #174).
• Updated s2_lnglat() and s2_point() to use wk::xy() (a record-style
  vctr) to represent point coordinates. This is much faster than the previous
  representation which relied on list() of external pointers (#181, #159).
• Added arguments planar and tessellate_tol_m to s2_as_text(),
  s2_as_binary(). Use planar = TRUE and set tessellate_tol_m to the
  maximum error for your use-case to automatically subdivide edges to
  preserve or "straight" lines in Plate carree projection on import (#182).
• Added arguments planar and tessellate_tol_m to s2_geog_from_text(), and
  s2_geog_from_wkb(). Use planar = TRUE and set tessellate_tol_m to the
  maximum error for your use-case to automatically subdivide edges to
  ensure or "straight" lines in Plate carree projection on export (#182).

s2 1.0.7

• Update the internal copy of s2geometry to use updated Abseil,
  fixing a compiler warning on gcc-11 (#79, #134).

s2 1.0.6

• Added support for STRICT_R_HEADERS (@eddelbuettel, #118).
• Fixed a bug where the result of s2_centroid_agg() did not
  behave like a normal point in distance calculations (#119, #121).
• Fixed a Windows UCRT check failure and updated openssl linking
  (@jeroen, #122).
