# Changelog

## 1.2.0

* Update dependencies
* Update mapnik-reference to support new Mapnik API version ([#498](https://github.com/mapbox/carto/issues/498))

## 1.1.0

* Update dependencies
* Update mapnik-reference to support new Mapnik API version ([#494](https://github.com/mapbox/carto/issues/494))

## 1.0.1

* Fix a error in the serialization process. ([#473](https://github.com/mapbox/carto/issues/488))

## 1.0.0

* Documentation is now available on https://cartocss.readthedocs.io. ([#473](https://github.com/mapbox/carto/issues/473))
* Warnings are emitted if properties are used that are `deprecated`, `unstable` or `experimental`.
There is a new command line / API switch (`-q / --quiet` / `quiet`) to suppress those warnings. ([#474](https://github.com/mapbox/carto/issues/474))
* Warnings are emitted if a layer has no associated styles or styles do not match a corresponding layer selector. ([#29](https://github.com/mapbox/carto/issues/29))
* New command line switch `-f / --file` to specify a file for output instead of `stdout`.
* carto now honors variable redefinition and uses the last defined value instead of the first one ([#338](https://github.com/mapbox/carto/issues/338)).
* All parameters of XML tags are now ouput in alphabetical order. This makes output more predictable.
* carto is now able to output a JSON variant of Mapnik XML. There is a new command line / API switch
(`-o / --output` / `outputFormat`) to choose the output format. Possible values are `mapnik` (default)
for Mapnik XML and `json` for the JSON variant (part of [#413](https://github.com/mapbox/carto/issues/413)).
For Mapnik XML all character data as tag content is now prefixed with CDATA.
* Expressions are allowed in filters e.g. `[height] % 50 = 0` or `[height] + 10 = 0`, fields have to be properly written within brackets
([#377](https://github.com/mapbox/carto/issues/377))
* carto now accepts custom references for validating rules (part of [#413](https://github.com/mapbox/carto/issues/413))
* The JavaScript API has been documented ([#479](https://github.com/mapbox/carto/issues/479))
* New symbolizer rules (work on the whole symbolizer) enable control of symbolizer serialization. Write e.g. `line: none` to suppress output
of the line symbolizer for this definition. Write e.g. `marker: auto` to output a markers symbolizer with default values. Symbolizer rules
are considered an advanced features and are never inherited to other definitions ([#477](https://github.com/mapbox/carto/pull/477)).
* Remove `millstone` from optional dependencies again ([#482](https://github.com/mapbox/carto/issues/482)).

### Breaking changes

#### Stylesheets

* The deprecated `name` attribute for layers is no longer supported. Use `id` instead.
* The deprecated color functions `husl` and `husla` are no longer supported. Use `hsluv` and `hsluva` instead.
* If you define a variable with the same name twice the latest defined value is now used in contrast to the first defined one as before.
* All parameters of XML tags are now ouput in alphabetical order. If you somehow depend on the order
of parameters (e.g. for tests) expect them to change.

#### API

* `carto.Renderer.render` and `carto.Renderer.renderMSS` now return an object `{ msg: Array, data: String }` instead of just a
string. `data` contains the output as before and `msg` now contains an array of error or warning objects.
In case of errors `data` is `null`.
* carto now only throws errors in case of program failures. All other style processing
related errors can be found in the `msg` property (see above).
* The constructor of `carto.Renderer` now only takes one options object
instead of a `env` and `options` parameter.
* The option `mapnik_version` and `validation_data` of `carto.Renderer` have
been renamed to `version` and `validationData` respectively.
* `carto.Renderer` now checks each option before forwarding them to the rendering
chain. Supported options are defined in the documentation. If you use a option that is
missing please open a issue.
