# Changes

## 0.7.18 - 2025-12-01

- Renamed features `use-rstar`, `use-rstar-0_8`, etc. to simply `rstar`, `rstar-0_8`, etc. (removing the `use-` prefix)
  and deprecated the old spelling.
  - <https://github.com/georust/geo/pull/1447>
- You can now serialize `rstar::AABB<Point>` and `rstar::AABB<Coord>` when enabling the `rstar` and `serde` features.
  - <https://github.com/georust/geo/pull/1450>

## 0.7.17 - 2025-07-25

- Add support to `wkt!` geometry creation macro for `LINE`, `RECT`, and `TRIANGLE` geometries.
  - <https://github.com/georust/geo/pull/1389>
- Add `empty` convenience initializer for constructing empty geometries
  - <https://github.com/georust/geo/pull/1363>
- Fix Clippy warning (surfaced in Rust 1.89) related to lifetime elision

## 0.7.16 - 2025-03-24

- Add `LineString::rev_lines` to iterate segments from end to start
  - <https://github.com/georust/geo/pull/1321>
- Add more concise Debug output for geometries (like WKT).
  NOTE: because geo-types allows some representations which are not supported by standard WKT, not all debug output is valid WKT. Do not attempt to treat debug as a stable format - it's unsuitable for interacting with programmatically. See the [`wkt` crate](https://crates.io/crates/wkt) for that.
  - https://github.com/georust/geo/pull/1302
- Rect and Triangle's `lines` and `coords` iterators and `to_polygon` method now return ccw-oriented geometry
  - https://github.com/georust/geo/pull/1308
- Implement approx::UlpsEq for geo-types, allowing a new kind of approximate equality check, based on counting the number of floats between two numbers.
  - https://github.com/georust/geo/pull/1312

## 0.7.15 - 2025-01-14

- Implement `RTreeObject` for `Triangle`.
- Implement `AsRef<Coord>` for `Point` and `Coord`.

## 0.7.14

  - <https://github.com/georust/geo/pull/1216>
- Add rstar compatibility for MultiPolygon
- Add multi-threading support to Multi\* geometries.
  - Feature-gated (`multithreading`), disabled by default, enabled by default when `geo-types` is used by `geo`

## 0.7.13

- POSSIBLY BREAKING: Minimum supported version of Rust (MSRV) is now 1.70
  - <https://github.com/georust/geo/pull/1134>
- Add feature for rstar v0.12.0
- Add num_rings and num_interior_rings methods to polygons.

  <https://github.com/georust/geo/pull/1071>
- Add `wkt!` macro to define geometries at compile time.
  <https://github.com/georust/geo/pull/1063>

## 0.7.11

- Bump rstar dependency
  <https://github.com/georust/geo/pull/1030>

## 0.7.10

- Implement `From<&Line>` for `LineString`

## 0.7.9

- Return `DoubleEndedIterator` from `LineString::points` and `LineString::points_mut`
  - <https://github.com/georust/geo/pull/951>
- POSSIBLY BREAKING: Minimum supported version of Rust (MSRV) is now 1.63
- Add `no_std` compatibility when the new default `std` feature is disabled
  - <https://github.com/georust/geo/pull/936>
- Support `rstar` version `0.10` in feature `use-rstar_0_10`.

## 0.7.8

- Rename `Coordinate` to `Coord`; add deprecated `Coordinate` that is an alias for `Coord`
- Pin `arbitrary` version to 1.1.3 until our MSRV catches up with its latest release
- Add `point.x_mut()` and `point.y_mut()` methods on `Points`
- Changed license field to [SPDX 2.1 license expression](https://spdx.dev/spdx-specification-21-web-version/#h.jxpfx0ykyb60)
  - <https://github.com/georust/geo/pull/928>
- Fix typo in deprecated attribute, which will become a compiler error in a future version of rustc.
  - <https://github.com/georust/geo/pull/932>

## 0.7.7

- Fixed: using empty `polygon![]` macro no longer requires including `line_string!` macro

## 0.7.6

- You may now specify `Geometry` rather than `Geometry<f64>` since we've added
  a default trait implementation. You may still explicitly declare the numeric
  type as f64, or any other implementation of `CoordNum`, but this should save
  you some typing if you're using f64. The same change applies to `Coordinates`
  and all the geometry variants, like `Point`, `LineString`, etc.
  - <https://github.com/georust/geo/pull/832>
- the `geometry` module now re-exports all the inner geometry variants, so you
  can `use geo_types::geometry::*` to concisely include `Point`, `LineString`, etc.
  - <https://github.com/georust/geo/pull/853>

## 0.7.5

- Add `split_x` and `split_y` methods on `Rect`
  - <https://github.com/georust/geo/pull/823>
- Add support for `Polygon` in `RTree`
  - <https://github.com/georust/geo/pull/351>
- Deprecate `GeometryCollection::from(single_geom)` in favor of `GeometryCollection::from(vec![single_geom])`
  - <https://github.com/georust/geo/pull/821>

## 0.7.4

- BREAKING: Make `Rect::to_lines` return lines in winding order for `Rect::to_polygon`.
  - <https://github.com/georust/geo/pull/757>
- Note: All crates have been migrated to Rust 2021 edition. The MSRV when installing the latest dependencies has increased to 1.56.
  - <https://github.com/georust/geo/pull/741>
- Macros `coord!`, `point!`, `line_string!`, and `polygon!` now support trailing commas such as `coord! { x: 181.2, y: 51.79, }`
  - <https://github.com/georust/geo/pull/752>
- Internal cleanup: Explicitly declare `use-rstar_0_8` and `use-rstar_0_9` features to be explicit which rstar version is being used. For backward compatibility, the `use-rstar` feature will still enable `use-rstar_0_8`.
  - <https://github.com/georust/geo/pull/759>
- Add missing size_hint() method for point and coordinate iterators on LineString
  - <https://github.com/georust/geo/issues/762>
- Add ExactsizeIterator impl for Points iterator on LineString
  - <https://github.com/georust/geo/pull/767>
- Extend `point!` macro to support single coordinate expression arguments `point!(coordinate)` (coordinate can be created with the `coord!` macro)
  - <https://github.com/georust/geo/pull/775>
- `LineString`, `MultiPoint`, `MultiPolygon`, `Triangle`, `MultiLineString` now have a new constructor `new(...)`. `GeometryCollection` has a `new_from(...)` constructor. `GeometryCollection::new()` has been deprecated - use `GeometryCollection::default()` instead. Do not use tuple constructors like ~~`MultiPoint(...)`~~ for any of the geo-types. Use `MultiPoint::new(...)` and similar ones instead.
