v1.6.0

• New features:
  • Add support for 2x2 metatiles (and 512px tiles). See #163, #166, and #169.
  • Cut child 256px tiles from 512px parent in the 2x2 metatile, rather than re-requesting that 256px bbox from database. See #158.
  • Pass nominal zoom instead of coordinates. See #161.
• Enhancements:
  • Drop parts of MultiPolygons which lie outside the clip boundary of the tile (primarily affects buildings and water layers). See #171.
  • Make queue sizes configurable, and default to smaller queue size to accomodate larger 2x2 metatiles. See #172.
  • Move existing tiles of interest (TOI) instead of copying it to avoid AWS Redis failover. See #122.
  • Load new TOI from file 'toi.txt', just as the TOI dump process saves to 'toi.txt'. See #122.
• Bug fixes:
  • Delete rejected jobs from SQS queue. See #173.
  • Trap MemoryError and let ops recover process. See #174.
  • Fix LinearRing error. See #175.

v1.5.0

• Emit additional metrics during intersection

v1.4.0

• When checking to see if a tile has changed, compare ZIP file contents only. (See #152)
• On WOF neighbourhood update, return a better error message for invalid dates. (See #154)
• Remove unused "layers to format" functionality. (See #155)

v1.3.0

• Roll back the use of psycopg2 connection pools. (See #149)

v1.2.1

• Fix connection leak: Track connections before trying to use them. (See #150)
• Fix issue processing WOF data with z coordinates: Ignore extra coordinates, e.g: z, in reprojection. (See #148)

v1.1.2

This is a backport of fixes to fix a production issue while we sort out v1.2.0, which has some issues around connection handling.

• Ignore extra coordinates (e.g: z) in reprojection function. See #148.

v1.2.0

• Improve performance of GeoJSON and TopoJSON format generation by using ujson (See #139)
• Improve performance of MVT format generation by using builtin round function (See #144)
• Reduce database pressure by use psycopg2 connection pools (See #141)
• Reduce database requests by registering hstore/json (See #142)
• Reduce memory usage during tile seeding (See #126)
• Expose unique option for seeding tile generator (See #127)
• Support long zooms (See #130)

v1.1.1

• Use queue name from message to acknowledge message. See #134.

v1.1.0

• Add command to dump the tiles of interest list to a text file
• Add support for generating metatiles
• Add priority queues implementation
• Increase topojson scale from 1024 -> 4096

v1.0.1

• Add bbox filter to test for partial overlapping, rather than intersecting, the bbox.
