v0.8.0-alpha

• [docs] Move documentation into this vector-datasource repo.
• Add bay, straight, fjord to water layer.

• Minor changes to support database migrations.

v0.7.0

• Release date: 2016-01-19.
• At mid and low zooms, roads have some properties dropped and are then merged together. This produces a huge reduction in the number of features in a tile and helps reduce both tile size and rendering time. Issue, Issue.
• Gym / fitness POIs are now available with kind: fitness in the pois layer. Issue.
• Swimming pools are now available with kind: swimming_pool in the water layer. Issue.
• Prisons are now available with kind: prison in both the pois and landuse layers. Issue.

• Aeroway gates are now available with kind: gate and aeroway: gate in the pois layer. Issue.
• Motorway links no longer show at zooms 10 and below. Issue.
• Buildings are now clipped to a 3x expanded tile boundary. This limits the maximum extent of buildings and can help if you've been experiencing rendering artefacts with very large buildings. Issue, Issue.
• Zoos and other tourist attractions have been "fixed up", and now contain a much wider range of features, as well as including more attributes such as surface type. Issue.
• Requires: tileserver v0.5.0 and tilequeue v0.7.0 and TileStache v0.7.0

v0.6.0

• Railway platforms are now present in the transit layer. Issue.
• Features related to winter sports are now present; with pistes in the roads layer as kind:piste, winter sports areas / resorts in the landuse layer with kind:winter_sports and various pois related to ski/snowboard hire available in the pois layer. Pistes issue. Areas issue, POIs issue.
• IATA codes are included as the iata property on airports for which the data is available in the pois and landuse layers. Issue.
• Pier lines are now included in the roads layer with kind:path, man_made:pier. Issue.

• Wine shops are now included in the pois layer. Issue
• Alcohol shops are now included in the pois layer. Issue
• The population attribute in the places layer is now always an integer. Issue.
• Requires: tileserver v0.5.0 and tilequeue v0.6.0 and TileStache v0.6.0

v0.5.3

• Release date: 2015-12-07. Live in prod: 2015-12-07.
• Fix bug where school points were not being exported as POIs. Ticket.
• Requires: tileserver v0.4.1 and tilequeue v0.5.1 and TileStache v0.5.1

v0.5.2

• Release date: 2015-12-04. Live in prod: 2015-12-04.
• Make hospital POIs visible at zoom 14 by default, instead of 15. Ticket.
• Fix regression which dropped parking aisles. Ticket.
• Requires: tileserver v0.4.1 and tilequeue v0.5.1 and TileStache v0.5.1

v0.5.1

• Release date: 2015-11-24. Live in prod: 2015-11-24.
• Update landuse query to use existing index
• Requires: tileserver v0.4.1 and tilequeue v0.5.1 and TileStache v0.5.1

v0.5.0

• Release date: 2015-11-13.
• Filter out duplicate POIs in pois, landuse, and buildings layers, preferring poi layer features. Includes density filter.
• Add neighbourhoods (and macrohoods and microhoods) from Who's On First in the places layer. New properties: min_zoom, max_zoom, kind_tile_rank, is_landuse_aoi.
• Remove neighbourhoods from OpenStreetMap.
• Add kind_tile_rank to kind=station features to enable filtering out of less important transit stations at low zooms (to reduce crowding). Weights stations that are shown at lower zoom levels by lines going through them. Lower numbers = more important.
• Stop duplicating building footprints into the landuse layer, and exclude building=no features. Include all building properties at all zooms (was limited to high zooms).
• Use addr:housename as building name if feature is a POI
• Add aerialway line features into the roads layer.
• Add back missing roads on park and other landuse boundaries that went missing when landuse_kind intercut was added.
• Add service levels to railroads features in roads layer to distinguish importance.
• Updated High Road classifier (zoom range, sort order) for service roads, including pedestrian streets, paths, and forest tracks so they are visible earlier.
• Add volume on building layer polygons to enable more sophisticated client-side filtering at mid zooms.
• Add city_wall lines and barrier lines to boundaries layer.
• Fix minor bug around missing water layer boundary lines.
• Add area to water boundary lines (so filtering of boundary lines can match polygons).
• Add townhall, laundry, dry_cleaner, and ferry_terminal to pois layer.
• Move centroid calculation out of database to post-processing step
• Updated formats to contain api_key parameter in tilejson metadata URL
• Requires: tileserver v0.4.1 and tilequeue v0.5.0 and TileStache v0.5.0

v0.4.1

• Release date: 2015-10-13
• Create new indexes to speed up query times
• Reduce boundaries query payload size
• Requires: tileserver v0.4.0 and tilequeue v0.4.1 and TileStache v0.4.1

v0.4.0

• Release date: 2015-10-06
• Fix regression in v0.3.0 where zooms 0 to zoom 8 country and region (state, province) features from OpenStreetMap were dropped from tiles (rolling back a change in v0.2.0)
• Greater diversity of label placements for POIs, landuse, and buildings result in more balanced selection of features visible at mid and high (neighborhood) zooms. The feature's minimum recommended visible zoom is now included as a property (eg: min_zoom=10.7763), useful for determining feature priority in client-side label collisions. Currently visibility should be calculated combined with area filters, we'll move that serverside in later releases.
• Add label positions for water bodies to the water layer noted as label_position=yes.
• Add label positions for buildings to the buildings layer noted as label_position=yes.
• Landuse label positions are now additionally available in the landuse layer directly, noted with label_position=yes.
• WARNING: The existing landuse-labels layer will be depreciated in a later release.
• Add location and layer tags to buildings features in the buildings layer to determine if something is location=underground or layer=-1 (like BART stations in San Francisco).
• Administrative boundary line improvements are back in the boundaries layer: now based on OSM relations, includes localized left- and right-names, and adds maritime_boundary=yes when the boundary is out in the deep sea. Note that this is slightly different than the maritime=yes tag that comes directly from OSM as we're calculating it using a custom spatial mask that will be improved over time.
• Add ferry lines starting at zoom 8 to road layer.
• Add airport runway lines starting at zoom 9 in the roads layer. Can be combined with landuse_kind attributes to throttle visibility.
• Requires: tileserver v0.4.0 and tilequeue v0.4.0 and TileStache v0.4.0
