Add an option to drop more points in dense areas than in sparse areas

2.12.0

• Add --drop-denser option to drop points in dense clusters in preference
  to those in sparse areas.

Limit guessed maxzoom to avoid spending too many tiles on polygon fill

2.11.0

• Change sqlite3 schema to deduplicate identical tiles
• Limit guessed maxzoom to avoid spending too many tiles on polygon fill

2.10.0

Do label generation after simplification, not before

2.9.1

• Do label generation after simplification, not before.

Generate label points; order by feature size

2.9.0

• Add an option to generate label points in place of polygons
• Add --order-smallest-first and --order-largest-first options
• When tiny polygons are being aggregated into dust, keep the attributes of the largest.

Visvalingam simplification; simplification option at maxzoom; winding order fix

2.8.1

• Improve precision of polygon ring area calculations

2.8.0

• Add the option to use a different simplification level at maxzoom

2.7.0

Fix crash in tile-join caused by wrong-way comparison

2.6.3

• Fix crash in tile-join caused by wrong-way comparison

Stop adding features to a tile if it can't possibly work, to limit memory use

2.6.2

• Stop adding features to a tile if it can't possibly work, to limit memory use
• Add --integer and --fraction options to tippecanoe-decode
• Carry strategies field from tileset metadata through tile-join

Better maxzoom and drop rate guessing

2.6.0

• Add another drop rate guessing options, from the same metrics -zg uses
• Reduce maxzooms being guessed a little:
  • Use 1.5 standard deviations, not 2, as the minimum distinguishable
  • Give overlapping polygons and linestrings more distinct indices

Extra coordinate precision; feature ordering by attribute; compression improvements

• Add an option to add extra detail at maxzoom that does not factor into guessing
• Restore the intended behavior that tiny polygons don't get further simplified
• Add an option to use single-precision floating point in tiles
• Improve polygon simplification by choosing a better start/end point
• Sort attribute values in tiles to make them compress a little better
• Fix dropping of "largest" points when there are duplicate points
• Add an option to prevent guessing a basezoom higher than the maxzoom
• Add --order-by and --order-descending options
