prepare for v0.2.7 release

This release is mostly around performance improvements.

Overall changes in benchmark performance since v0.2.6: Direct bench: -6.7% Inverse bench: -22.5%

• Prefer built in math methods over custom implementations in geomath module. This is an internal refactor and shouldn't affect users.
• Speed up Direct/Inverse methods by hardcoding GEODESIC_ORDER. In practice this was already hardcoded in some places, so there was no benefit to having it a configurable parameter. Direct bench: -4.4823% Inverse bench: -15.856%
  • See https://github.com/georust/geographiclib-rs/pull/70
• Speed up Direct/Inverse methods a little by simplifying atan2d Direct bench: -2.8% Inverse bench: -2.5%
  • See https://github.com/georust/geographiclib-rs/pull/71
• Speed up Inverse methods a little by using constantly sized arrays, rather than slices. Inverse bench: -5%
  • See https://github.com/georust/geographiclib-rs/pull/72

prepare for v0.2.6 release

• Exclude test fixture data and development scripts from published crate to reduce published crate size by ~20kb
  • Thanks to @weiznich!
  • https://github.com/georust/geographiclib-rs/pull/66
  • https://github.com/georust/geographiclib-rs/pull/67

prepare for 0.2.5 release

• Make GeodesicLine public, which can be more efficient when placing multiple points along a single line.
  • https://github.com/georust/geographiclib-rs/pull/63
  • Thanks to @JMdoubleU for their work here.

prepare for 0.2.4 release

• Performance improvements for direct and indirect geodesic calculations
• Remove lazy_static dependency
• Thanks to contributor @valarauca for their work on performance and code cleanup.

prepare for 0.2.3. release

New Features

• Added PolygonArea to allow calculating perimeter and area of a polygon on a geodesic.
• Added accurate feature (enabled by default) for highly accurate PolygonArea calculations.

This patch release includes only small clippy/lint fixes, and should not appreciably affect behavior. Thanks to @Quba1 for the cleanup!

• https://github.com/georust/geographiclib-rs/pull/45

prepare for 0.2.1 release

This patch release has no API changes, but fixes some correctness issues around some of the edge cases represented in Karney's GeodSolveXX tests.

My gratitude to Charles Karney for publishing good tests and especially to Stony Lohr (@stonylohr) for implementing them here.

And also thank you to Stony for building out our CI and your other project maintenance work!
