v1.0.0-pre2

• Release date: 2016-08-31 (dev build only as public preview 2016-09-07)

• See detailed Breaking changes, New features, Bug fixes, and Internal Changes sections below.

• Requires: tileserver v0.8.0-pre2 and tilequeue v0.11.0-pre2

  BREAKING CHANGES (v1.0.0-pre2)

• all layers: Revert to 2 letter language codes to remove client 3-char to 2-char shim logic, with better fallbacks. (#972)

• boundaries, places, and roads layers: Remove raw Natural Earth scalerank (see min_zoom instead) and labelrank properties. (#992)

• buildings layer: remove label placements from low- and mid-zooms, keep at zoom 16+. (#679)

• landuse layer: Low- and mid-zoom landuse polygons are now merged within the same kind values to significantly reduce file size. Some properties, like name, id, sport, religion, and surface are dropped, and the area is recalculated for new combo polygons. Planned work will add back some detail by adding scale_rank classes pre-merge (matching buildings layer behavior). (#583)

• landuse layer: Remove label placements for cemetery, farm, forest, forest, golf_course, grave_yard, military, national_park, natural_forest, natural_wood, nature_reserve, park, pitch, plant, protected_area, quarry, recreation_ground, substation, village_green, wastewater_plant, water_works, winter_sports, wood, works features, moving them to pois layer. Remaining label placements are recommended for text only label treatment.(#742)

• landuse layer: remove label placements from low- and mid-zooms, keep at zoom 15+. (#679)

• places layer: Additional locality changes for places layer to normalize place layer kinds: capital changes to country_capital, state_capital changes to region_capital, scientific_station localities get their own kind_detail, and other bug fixes for (#840). (#931)

• pois layer: Remove the cuisine property (see new kind_detail instead). (#719)

• pois layer: Modify default min_zoom for gate features. Gates on major roads are now visible at zoom 14, gates on intermediate roads at zoom 15, gates on minor roads at zoom 16, and gates not on roads at zoom 17 (was all zoom 15). (#820)

• roads layer: Remove aerialway, highway, piste_type, railway, in favor of coalescing their values into a new kind_detail property (and change incorrect subkind reference in documentation to kind_detail). (#970)

• transit layer: rename root_relation_id property to root_id, matching new building layer configuration. (#969 and #653)

• water layer: Remove duplicative and poor resolution sea polygons (but keep their label centroids) to save Venice and other cities from early global warming! This also addressed excessive sea labels in most Mapzen house styles. (#951)

  NEW FEATURES (v1.0.0-pre2)

• tilejson: Major upgrade to reflect all layers and properties. (#938)

• versioning: Add semantic versioning (semver) document detailing the promises Tilezen makes about major, minor, and patch versions and data model changes. (#948)

• buildings layer: Building parts may receive a root_id corresponding to the building feature, if any, with which they intersect. (#653)

• landuse layer: Add graveyard features. (#742)

• landuse layer: Add camp_site features for camp grounds. (#875)

• pois layer: Add cemetery, farm, forest, forest, golf_course, military, national_park, natural_forest, natural_wood, nature_reserve, park, pitch, plant, protected_area, quarry, recreation_ground, substation, village_green, wastewater_plant, water_works, winter_sports, wood, works features with adjusted zoom ranges over their previous availability in the landuse layer as label placements. All remaining label placements in the landuse layer are no longer recommended for icon label treatment. (#742)

• pois layer: Add graveyard features. (#742)

• pois layer: Add art gallery features. (#990)

• pois layer: Add kind_detail property sourced from sport for pitch features and sourced from cuisine for biergarten, pub, bar, restaurant, fast_food, cafe kinds (removing the cuisine property). (#719)

• roads layer: To support highway shields a new shield_text property has been added, network values have been normalized (and bicycle networks are now excluded). An example: for "US 101" we now store network of US:US and shield_text of 101. Multiple shields are supported via optional all_networks and all_shield_texts lists (which work in GeoJSON and TopoJSON but not MVT formats, follow mapbox-vector-tile/#64 for a fix). The ref property remains available but is less useful for shield construction. (#192 and #896)

  BUG FIXES (v1.0.0-pre2)

• all layers: Support fractional zoom for POIs, places, and other featues which were only appearing at the next whole integer tile, and rounds min_zoom values to 2 decimal places. For example: a feature with min_zoom of 14.8 was only appearing in zoom 15 tiles when it should have appeared in the zoom 14 tile. (#976)

• boundaries layer: Correct bug where sort_key mapping wasn't updated for new boundary kind values from v1.0.0-pre1. (#1012)

• places layer: Adjust default zoom ranges for Natural Earth localities at the low-zooms and Natural Earth and OpenStreetMap localities at mid- and high-zooms. (#981 and #982)

• places layer: Exclude region_capital=false properties. (#1003 and #931)

• pois layer: Add OpenStreetMap source attribution per feature. (#922)

• pois layer: Start querying for pois at z4, not z2 (matching the landuse layer). (#994)

• pois layer: Show large camp_site features at earlier zooms. (#875)

• pois layer: Removed transit halt, station, stop, and tram_stop features marked as historic. (#661)

• pois and landuse layers: Normalize operator values for United States National Park Service, United States Forest Service, and National Parks & WildlWildlifeife Service NSW in the U.S.A. and Australia. (#927)

• roads layer: Pedestrian paths and piers were missing bicycle: designated and related tags. Now that they are exported, they are correctly also decorated as is_bicycle_related: True. (#832)

• roads layer: Add additional properties sidewalk_left and sidewalk_right to all road layer features. (#605 and #986)

• roads layer: Remove crossing, sidewalk, sidewalk_left and sidewalk_right properties for road merge. (#993)

• roads layer: Drop meaningless id property on merged features. (#952)

• transit layer: Add OpenStreetMap source attribution per feature. (#935)

  DOCUMENTATION CHANGES (v1.0.0-pre2)

• documentation: Update earth layer documentation to reflect additional line and point geometry types. (#808)

• documentation: Update boundaries and landuse layer documentation to reflect barriers moving into the landuse layer. (#932)

• documentation: Update places layer documentation to reflect new kind and kind_detail values, locality, suburb, quarter, state, province, region, capital, and other changes. (#934)

• documentation: Update buildings layer documentation to reflect new kind and kind_detail values and building_part changes. (#933) and related (#842)

• documentation: Update roads layer documentation to reflect new kind and kind_detail values, and remove erroneous reference to exit. (#936)

• contributing: Adding a step to create a test_config.yaml file. (#1001)

  INTERNAL CHANGES (v1.0.0-pre2)

• performance: Move label centroid calculation to database to reduce network pressure on the database (post processing transform needed too much geometry) in landuse, water, earth, and buildings layers. (#965)

• performance: Add pois indexes for OpenStreetMap polygon and point tables to improve query time. (#983)

• database: Convert Postgres PostGIS database to utilize osm2pgsql's --hstore-all option. (#876)

• database: Convert Postgres PostGIS database projection to EPSG:3857. (#908)

• database: Convert min_zoom properties to REAL from INT to support fractional values. (#976)

• import: Remove default -W UTF-8 from data import config for shp2pgsql. (#946)

• import: Add shim in apply non planet sql to better accommodate invalid geometries. Track longer term fix in #979. (#1003)

• indexes: Update road indexes to refer to mz_road_level alone. (#956)

• tests: Correct test failure for hotels as upstream data had changed. (#959)

• tests: Ensure that when config_all_layers is set, the all layer is requested. (#974)
