Attribute type control; maxzoom guessing; non-mbtiles output; tile-join layer control

1.17.1

• Add -T option to coerce the types of feature attributes

1.17.0

• Add -zg option to guess an appropriate maxzoom

1.16.17

• Clean up JSON parsing at the end of each FeatureCollection
  to avoid running out of memory

1.16.16

• Add tile-join options to include or exclude specific layers

1.16.15

• Add --output-to-directory and --no-tile-compression options

1.16.14

• Add --description option for mbtiles metadata
• Clean up some utility functions

1.16.13

• Add --detect-longitude-wraparound option

1.16.12

• Stop processing higher zooms when a feature reaches its explicit maxzoom tag

Remove polygon splitting; add option to decode specific layers

1.16.11

• Remove polygon splitting, since polygon cleaning is now fast enough

1.16.10

• Add a tippecanoe-decode option to specify layer names

1.16.9

• Clean up layer name handling to fix layer merging crash

1.16.8

• Fix some code that could sometimes try to divide by zero
• Add check for $TIPPECANOE_MAX_THREADS environmental variable

1.16.7

• Fix area of placeholders for degenerate multipolygons

1.16.6

• Upgrade Wagyu to 0.3.0; downgrade C++ requirement to C++ 11

1.16.5

• Add -z and -Z options to tippecanoe-decode

1.16.4

• Use Wagyu's quick_lr_clip() instead of a separate implementation

Polygon and layer tag bug fixes

• Upgrade Wagyu to bfbf2893
• Associate attributes with the right layer when explicitly tagged
• Choose a deeper starting tile than 0/0/0 if there is one that contains all the features

Switch to Wagyu for polygon topology correction

• Switch from Clipper to Wagyu for polygon topology correction
• Prevent tile-join from creating multiple attributes with the same name
• Fix compiler warnings and uninitialized variables

Bug fix for --drop-smallest-as-needed

Stop --drop-smallest-as-needed from always dropping all points

New strategies for making tiles smaller

• New strategies for making tiles smaller, with uniform behavior across
  the whole zoom level: --increase-gamma-as-needed,
  --drop-densest-as-needed, --drop-fraction-as-needed,
  --drop-smallest-as-needed.
• Option to specify the maximum tile size in bytes
• Option to turn off tiny polygon reduction
• Better error checking in JSON parsing

Consistent feature dropping

• Make -B/-r feature-dropping consistent between tiles and zoom levels

Better polygon simplification; layer merging in tile-join

• Add --detect-shared-borders option for better polygon simplification
• Enforce that string feature attributes must be encoded as UTF-8
• Whitespace after commas in tile-join .csv input is no longer significant
• Tile-join is multithreaded and can merge multiple vector mbtiles files together

Add the ability to specify layer names within the GeoJSON input

• Add the ability to specify layer names within the GeoJSON input

Fix feature IDs in tile-join and rare polygon clipping errors

• Don't try to revive a placeholder for a degenerate polygon that had negative area
• Pass feature IDs through in tile-join
