ENHANCEMENTS

• Significant performance improvements to reduce p99 file sizes globally (-45%) at all zooms to under 200 kb, with some improvements for low-zoom p50 sizes. Changes include: geometry simplification at low zooms, pushing some features like unclassified roads to the next zoom, dropping names on short lines and dropping other properties at mid-zooms to also allow more aggressive merges to multi-lines and multi-polygons, and more sophisticated handling of max zoom and overzoom tiles for buildings and addresses. Further reductions can be achieved by configuring Tapalcatl to selectively drop layers and name translations (eg to drop earth and transit layers or only keep English and Urdu names) depending on your business needs. (Above) Chart shows sizes in kilobytes, based on commonly requested top 100,000 tiles at 512 pixel zooms. NOTE: all other zooms in this document use nominal 256 pixel zooms, offset by 1.
• Internationalization is now feature complete by extending disputed boundary point-of-view handling fully into mid- and high-zooms with extensive paired data edits upstream in OpenStreetMap, using Natural Earth as a sanity check for country names, and consideration of common and less common edge cases, including Taiwan and Somaliland.
• MapLibre support with buffered tiles and connivence properties like pre-calculating shield text length allow Tilezen tiles to more easily be styled in MapLibre and MapboxGL, thus extending support beyond Tangram.
• boundaries: Add disputed boundary line point-of-view (POV) for mid- and high-zoom features sourced from OpenStreetMap (OSM), including extensive upstream editing in OSM to match Natural Earth's low-zoom disputed area modeling in earlier releases. New unrecognized_dispute kind and disputed_by property. (Issue #1901)
• boundaries: Add missing Cyprus line-of-control (aka "green line") as it has custom admin_level tagging. (Issue #1898)
• boundaries: Add Ukraine point-of-view for disputed boundaries. (Issue #1911)
• boundaries: Add disputed boundary in South China Sea scoped to China's point-of-view (POV). (Issue #1983)
• boundaries: Mark some Natural Earth low-zoom boundaries as default unrecognized, including for Abkhazia, Donbass, Nagorno-Karabakh, Northern Cyprus, Somaliland, South Ossetia, and Transnistria. (Pull request #2072)
• buildings: Add additional non-OpenStreetMap buildings from the Microsoft sidecar in Daylight distribution.
• places: Always validate OpenStreetMap-sourced country, dependency and disputed labels against Natural Earth and new ISO and TLC point-of-views. (Issue #2075, #2076, and #2077 and pull request #2069)
• places: Add recasted Australia "suburbs" from OpenStreetMap as locality features to match local expectations. (Pull request #2070)

• all layers: Vary the MVT tile extent so 8192 is only used on max_zoom (and 4096 earlier) to optimize file size while preserving overzooming. (Issue #1985)
• all layers: Are now MVT v2 spec compliant, via related changes in Tilezen's mapbox-vector-tile v2.0.0 release.

BUG FIXES

• boundaries: Show all missing disputed lines for point-of-view (POV) in low-zooms (remove min_zoom filter). (Issue #1970)
• boundaries: French region lines show too early, switch all from funky scale_rank mapping to Natural Earth's min_zoom property. (Issue #2062)
• boundaries: Drop additional ID and name properties at mid-zooms and merge lines at high-zooms. (Issue #2007)
• boundaries: Revert poor tolerance config change from earlier release, this improves visual look for 512-pixel tiles in MapboxGL-based styles. (Issue #1980)
• boundaries: Fix some incorrectly marked maritime boundaries with new buffered land masking file. (Pull request #2073)
• buildings: Add root_id = id to simplify MapboxGL-based styles. (Issue #2092)
• buildings: Remove small buildings, reduce building geometry details, and remove some properties at mid- and high-zooms. (Pull request #2052)

Drop more bus, walking, and bicycle network properties at low- and mid-zooms. Drop general road shield properties at earlier zooms by kind. Drop other properties at earlier zooms. Selectively drop landuse_kind from mid-zooms by kind. Shift unclassified roads min_zoom back to 12 from 11 as that's more common outside the USA than previously explored and negatively affected tile size. (Issue #2008)
• roads: Remove additional low- and mid-zoom ferry and aeroway properties to enable more line merging. (Issue #2017, issue #2018, and pull request #2056)
• roads: Revert poor tolerance config change from earlier release, this improves visual look for 512-pixel tiles in MapboxGL-based styles. (Issue #1980)

ENHANCEMENTS

• boundaries: Add more kind:* point-of-view (POV) from Natural Earth for low zooms for disputed boundary lines, expanding on the v1.7 effort to also include region boundary disputes. (Issue #1840)
  • 
  • To handle disagreements about the location of borders, the kind may be prefixed with unrecognized_, e.g: unrecognized_country (was unrecognized in v1.7), unrecognized_macroregion, unrecognized_region, unrecognized_county for differing viewpoints (see kind:xx below).
  • kind:xx: alternate kind according to the viewpoint of country code xx. If you want to show features according to a particular viewpoint, then use kind:xx if it exists and fall back to kind if not. The range of values is the same as for kind. Note that the viewpoints are either lower-case ISO 3166-1 alpha-2 codes or the pseudo-code iso.
• boundaries: Add OSM alternate viewpoints for country, region, and counties boundaries. (Issue #1810)
  • We track two kinds of features from OSM for indicating disputes:
    1. claims, which have boundary=claim, claimed_by=*, admin_level=* tags. These indicate borders which aren't generally recognized, but should appear in the viewpoint of the claimed_by= value. additionally, extra viewpoints which don't make a claim for themselves but still want the claimant's view reflected in their own can be specified in a recognized_by=* tag.
    2. disputes which have dispute=yes or disputed=yes, plus a list of disputant viewpoints in the disputed_by=* tag. when a viewpoint is listed in disputed_by then the boundary will have its kind:xx set to unrecognized_* (where XX is the viewpoint / country code and * is the kind of boundary it is).
• earth: The former OpenStreetMapData.com source is now hosted by FOSSGIS at osmdata.openstreetmap.de and the source property has been updated. Issues (#1855) and (#1859)
• landuse: Add kind_detail for aerodrome enhancement and backfill kind_detail on aerodromes with values, public, private, military_public, airfield, international, regional, gliding, and add optional aerodrome_passenger_count property indicating the number of passengers through the aerodrome per year sourced from Wikidata. (Issues #1277 and #1873)
• places: Backfill country_capital and region_capital booleans from Natural Earth on high-zoom OSM features, including point-of-view. (Issue #1810)
• places: Add point-of-view (POV) to capitals from Natural Earth data to all zooms. (Issue #1840)
  • country_capital:xx: when present, either true or false to override the country_capital value for XX's viewpoint. Note that the viewpoints are either lower-case ISO 3166-1 alpha-2 codes or the pseudo-code iso, same as for kind:xx on boundaries.
  • region_capital:xx: when present, either true or false to override the region_capital value for XX's viewpoint. Note that the viewpoints are either lower-case ISO 3166-1 alpha-2 codes or the pseudo-code iso, same as for kind:xx on boundaries.
• places: Add wikidata_id Wikidata ID concordance to features. (Issue #858)
• pois: Add optional Wikidata wikidata_id concordances. (Issue #858)
• pois: Add kind_detail for aerodrome enhancement and backfill kind_detail on aerodromes with values, public, private, military_public, airfield, international, regional, gliding. (Issues #1277 and #1873)
• pois: Distinguish military airfield from generic aerodrome. (Issue #1580)
• roads: Ensure runways get kind_detail polish by intersecting them with landuse aerodrome polygons using new overlap function. (Issue #1852)
• roads: Add missing railway types of disused, miniature, preserved. (Issue #955)
• water: Add optional Wikidata wikidata_id concordances. (Issue #858)

• buildings: Check that building height is in a sensible range by limiting tallest structures to 1000 meters. (Issue #1850)
• earth: Add variable min_zoom to low zoom features from Natural Earth. (Issue #1287)
• places: Update Who's On First dump to reflect new and deprecated neigbourhoods. Issues (#1808) and (#1869)
• pois: Prefer elevator over subway_entrance when both are true. (Issue #1876)

• pois: Prefer bus_stop over generic transit platforms. (Issue #1874)
• pois: Improve the collision_rank of fast_food POIs by adjusting several other's rank. (Issue #1875)
• pois: Correct generator kind_detail values by using a new OpenStreetMap property. (Issue #1578):

• roads: Add low-zoom toll property from Natural Earth to match earlier high-zoom data from OpenStreetMap. (Issue #1817)
• roads: Add new road construction kind with kind_detail from the usual kind from zoom 12+. (Issue #394)
  • kind_detail: motorway, motorway_link, trunk, primary, secondary, tertiary, trunk_link, unclassified, residential, road, primary_link, secondary_link, living_street, service, pedestrian, track, cycleway, bridleway, tertiary_link, footway, steps, `corridor
• water: Reduce the marine water labels visible at zoom 8 by limiting number of bays in the tile to the largest 10. (Issue #1838)
  • The kinds bay, strait and fjord are ranked by size and given a kind_tile_rank property that starts from 1 and counts up as the feature gets smaller. Note that the ranking is done on a "metatile", which means that each tile (of size 256px, 512px or other) won't necessarily contain the full range from 1 to N of kind_tile_ranks.
• water: Water boundary lines now indicate intermittent property (playas), matching their polygons. (Issue #1249)

• roads: Major changes to network and shield_text to support fallback international road shields. When no network is provided by a ref is, a 2-char country code will be exported as the network value based on the location of the road, like AM or US. Issue #135.
• roads: Minor changes to network and shield_text to support USA road shields, including modifier postfix: US:AK, US:AL, US:AR, US:AZ, US:BIA, US:BLM, US:CA, US:CO, US:CT, US:DC, US:DE, US:FL, US:FSH, US:FSR, US:GA, US:HI, US:I:Alternate, US:I:Business, US:I:Bypass, US:I:Connector, US:I:Historic, US:I:Scenic, US:I:Spur, US:I:Toll, US:I:Truck, US:I, US:IA, US:ID, US:IL, US:IN, US:KS, US:KY, US:LA, US:MA, US:MD, US:ME, US:MI, US:MN, US:MO, US:MS, US:MT, US:NC, US:ND, US:NE, US:NH, US:NJ, US:NM, US:NV, US:NY, US:OH, US:OK, US:OR, US:PA, US:RI, US:SC, US:SD, US:TN, US:TX, US:US:Alternate, US:US:Business, US:US:Bypass, US:US:Connector, US:US:Historic, US:US:Scenic, US:US:Spur, US:US:Toll, US:US:Truck, US:US, US:UT, US:VA, US:VT, US:WA, US:WI, US:WV, and US:WY. Issue #1387.
• roads: Modify min_zoom of track kind to show 1 zooms earlier by default when surface is gravel or tracktype is not grade3, grade4, or grade5. Issue #1251.
• roads: Modify min_zoom of track kind to show 2 zooms earlier by default when surface is paved, asphalt, concrete or tracktype is grade1 (but not for access private). Issue #1251.
• roads: Modify min_zoom of unclassified kind to show 1 zoom earlier by default. Issue #1250.
• roads: Show important cycling and walking routes at earlier zooms by adjusting the min_zoom of path, major_road, and minor_road kinds. This means that min_zoom values are now variable for features of the same kind, depending on their importance in the bicycle and walking networks; in earlier releases they all shared the same min_zoom. See #1172.
• water: Add fountain kind.
• water: Add reef kind, with optional kind_detail values of coral, rock, and sand.

BUG FIXES

• boundaries: Restore full border to Gaza Strip. Issue #1257.
• landuse: MVT format now includes many more polygons that were dropped in earlier versions that used different format driver.
• places: Fix spelling of ~60 locality (city) names at low-zooms in places layer by taking Natural Earth update. #1140.
• roads: European primary network calculation now prefers local networks instead of e-road. Issue #1483.
• roads: Add surface property at more zooms. Issue #1252.
• water: Fix missing ocean water by making Natural Earth ne_10m_ocean features OGC valid in PostGIS.

DOCUMENTATION CHANGES

• Correct the Greek language 2-char code from gr to el in the Semantic Versioning statement.
• Change references to Mapzen (RIP) to Tilezen.
• Update MapboxGL demo, thanks to Apollo Mapping
• Use service wording changes (Less > Fewer)
• Updated Layers documentation for v1.5 schema changes.
• TODO: Updated tilejson/tilejson.json.erb for v1.5 schema changes.

INTERNAL CHANGES

• Change references to Who's On First gazetteer source to whosonfirst.org from whosonfirst.mapzen.com.
• Refactors to support RAWR tile builds in queries/jinja and elsewhere.
• Add support for multiple localized names from Natural Earth 4.x by adding new transform convert_ne_l10n_name for 2-char language codes.
• Use a Tilezen curated country admin polygon layer to determine country codes PIP for intermediate processing (this layer is not exported in final tiles).
• Add new function to calculate linear overlap with polygons, useful for road in country calculation.
• Add new function to calculate point in polygon (PIP), useful in POI in country calculation.
• Updates to Tilezen curated buffered_land layer for marine boundary lines.
• Be more robust to only add database columns when they don't already exist.
• Support easier creation of generative tests for points, lines, and polygons.
• Continued migration to generative tests instead of live-data OpenStreetMap tests via Overpass.
• Switch to generating MVT format with Coanacatl, which wraps Wagyu and VTZero.
• Requires Postgresql 9.5. Issue #1319.
• Upgrade to CircleCI 2.0 for continuous integration.
• Refactor all OpenStreetMap to Tilezen ETL logic for network and ref > shield_text to support international road shields based on fuzzy data and missing country code data, including specific functions per country.
• Add max_zoom_filter to remove features with a max_zoom if it's < nominal zoom.
• Add whitelist for fence kind_detail values.
• This will be the last set of database migrations provided. All future releases will assume "global" RAWR tile builds.
