[0.6.0] - 2026-09-05

Classification.nearest_point_on_line/3 snaps WGS84 points to LineString and MultiLineString segments with raw distance and route-location metadata
Classification.point_on_line?/3 tests line membership with an inclusive, unit-aware geodesic tolerance
Measure.line_slice/3 snaps two points and extracts their LineString section in source route order
Measure.point_to_line_distance/3 measures the raw distance using the same snapping semantics

Measure.final_bearing/2 — computes the bearing at the destination point (as opposed to bearing/2 which gives the initial bearing at the origin)
Helpers.assert_wgs84!/1 and guards on all public geodesic functions against non-WGS84 SRIDs
Math.approx/2 for rounding Point coordinates to a given precision

Measure.distance/3 now returns raw geodesic values; callers can use Math.rounded/2 for display rounding
Measure.close_to/4 uses raw distance and includes points exactly at the maximum threshold
Classification.nearest_point/3 ranks candidates by raw distance
Empty geometries now return zero for aggregate measurements, :error for point-producing measurements, and false for polygon containment
WGS84 validation now checks every member of geometry and point collections recursively
Length and area APIs now reject unsupported units with explicit ArgumentError messages
Newly constructed WGS84 geometry and measurement-derived points now carry srid: 4326; coordinate-only transformations preserve the source SRID
Circle and destination options consistently use :units; unknown option names now raise instead of silently using defaults
The supported runtime floor is now Elixir 1.15 / OTP 26, with CI coverage through Elixir 1.18 / OTP 28
Non-WGS84 SRID errors now explain reprojection, the nil assumption, and how to correct stale WGS84 metadata explicitly

Measure.along/3 now geodesically interpolates mid-segment points instead of snapping to the nearest vertex
Measure.length_of/2 now measures independent geometry paths without adding fictitious segments between them

First release.
