Version 7.0.1

2020-06-01

Bug Fixes:

  • Update dependencies to avoid security vulnerabilities

Version 7.0.0

2020-05-14

Breaking changes:

  • Drop support for Node.js 10

Version 6.0.0

2020-04-05

Breaking changes:

  • Stops providing several classes and delegating how to build this library to the clients (e.g: Windshaft-CartoDB). Now it provides a factory method that creates the required backend instances and exposes them along with the MapConfig model and the Datasource helper. Everything else is removed, even the version info of dependencies such as grainstore, node-mapnik, and mapnik.
  • New signature for onTileErrorStrategy:
    • From onTileErrorStrategy(err, tile, headers, stats, format, callback) to async onTileErrorStrategy(err, format)
    • From callbacks to promises to match with the new internal signature for renderers
  • Improved renderer reporting:
    • Now renderer.getStats() returns a Map<key, value> with information about renderer's performance

Announcements:

  • Bumps acorn from 7.1.0 to 7.1.1
  • Bootstrap system fonts to register them into mapnik and make them accessible to CartoCSS Renderer in Grainstore
  • Rename MapValidatorBackend by MapValidator
  • Now rendererCache implements a new method .getStats() -> Map<key, value> where accumulates stats from different renderers alive in the cache
  • Upgrades @carto/cartonik to version 0.8.0
  • New signature for renderers:
    • .getTile(z, x, y, callback) => .getTile(format, z, x, y) -> Promise
    • .getMetadata(callback) => .getMetadata() -> Promise
    • .close(callback) => .close() -> Promise
  • Removes format argument in adaptor's constructors as is no longer needed.
  • In renderers, applied some ES7/8 features: classes, async/await, spread syntax, etc..
  • Fix test that fails quietly
  • Removed jshint as linter in favour of eslint to check syntax, find problems, and enforce code style
  • Remove deprecated coverage tool istanbul, using nyc instead
  • Stop using two different tools for package management, testing, and any other developer workflow
    • Removes Makefile and related bash scripts
    • Use npm scripts as the only tool for testing, CI and linting.
    • Simplified CI configuration
  • Improved documentation:
    • Merge different documents file into README.md
    • Remove outdated sections
    • Update old sections
    • Added missing sections

Version 1.0.0

2015-09-30

From Semantic Versioning:

Major version zero (0.y.z) is for initial development. Anything may change at any time. The public API should not be considered stable.

As we are following Semantic Versioning and we didn't release any major > 0 we could change anything with next minor bump but I would like to make this version 1.0.0 so this stays as the first public API.

A lot of things have changed/moved/disappeared, internal API has nothing to do with previous one.

List of changes:

  • RendererCache now works with MapConfig providers (needs documentation).
  • Backends hold a RendererCache, so they also work with MapConfig providers
  • More specific backends: tiles, previews, map, validator, attributes
  • Express no longer a dependency
  • Makefile picks tests with find, no need to add files manually
  • Example contains a basic server similar to original windshaft's server
  • Test environment now extends development
  • Mapnik factory no longer supports snapToGrid and clipByBox2d
  • RendererFactory now supports a mapnik filter to retrieve all mapnik layers
  • Starts using debug to no output to stdout by default
  • Removes stats code: profiler, client, reporter
  • Major rewrite of tests to not rely on server
  • Support for MVT format in mapnik renderer
  • Official support for plain layer type: options include color and imageUrl.

See Multilayer-API.md for more details.
  • Layergroup creation returns metadata for all layers (#338) Keeps backwards compatibility for torque metadata
