+
+## 1.26.0
+
+Released 2015-01-27
+
+Announcements:
+ - Upgrades windshaft to 0.35.0, supports mapconfig version `1.3.0`
+
+
+## 1.25.0
+
+Released 2015-01-26
+
+Announcements:
+ - No more signed maps (#227 and #238)
+    - Splits template maps endpoint into its own controller
+    - Removes TemplateMaps dependency on SignedMaps
+     - Token validation is done against the template
+     - Template is always extended with default values for auth and placeholders
+     - MapConfig is extended, in order to validate auth_tokens, with template info:
+        - template name
+        - template auth
+     - No more locks to create, update or delete templates
+        - Trusting in redis' hash semantics
+        - Some tradeoffs:
+            * A client having more templates than allowed by a race condition between limit (HLEN) check and creation (HSET)
+            * Updating a template could happen while deleting it, resulting in a new template
+            * Templates already instantiated will be accessible through their layergroup so it is possible to continue requesting tiles/grids/etc.
+     - Authorisation is now handled by template maps
+    - Template instantiation returns new instances with default values if they are missing
+
+
+New features:
+ - Basic layergroup validation on named map creation/update (#196)
+ - Add named maps surrogate keys and call invalidation on template modification/deletion (#247)
+    - Extends TemplateMaps backend with EventEmitter
+        - Emits for create, update and delete templates
+    - VarnishHttpCacheBackend will invalidate a varnish instance via HTTP PURGE method
+        - In the future there could be more backends, for instance to invalidate a CDN.
+    - NamedMapsEntry has the responsibility to generate a cache key for a named map
+        - It probably should receive a template/named map instead of owner and template name
+    - SurrogateKeysCache is responsible to tag responses with a header
+        - It also is responsible for invalidations given an Invalidation Backend
+        - In the future it could have several backends so it can invalidates different caches
+    - SurrogateKeysCache is subscribed to TemplateMaps events to do the invalidations

-**TILES**
-
-[GET] subdomain.cartodb.com/tiles/:table_name/:z/:x/:y.[png|png8|grid.json]
-
-Args:
-
-* sql - plain SQL arguments
-* interactivity - specify the column to use in UTFGrid
-* cache_buster - Specify an identifier for the internal tile cache.
-                 Requesting tiles with the same cache_buster value may
-                 result in being served a cached version of the tile
-                 (even when requesting a tile for the first time, as tiles
-                 can be prepared in advance)
-* cache_policy - Set to "persist" to have the server send an Cache-Control
-                 header requesting caching devices to keep the response
-                 cached as much as possible. This is best used with a
-                 timestamp value in cache_buster for manual control of
-                 updates.
-* geom_type - override the cartodb default
-* style - override the default map style with Carto
+The [docs directory](https://github.com/CartoDB/Windshaft-cartodb/tree/master/docs) contains different documentation

-**STYLE**
+Examples
+--------
 
-[GET/POST] subdomain.cartodb.com/tiles/:table_name/style
-
-Args:
-
-* style - the style in CartoCSS you want to set
-* style_version - the version of the style for POST
-* style_convert - request conversion to target version (both POST and GET)
-
-
-**INFOWINDOW**
-
-[GET] subdomain.cartodb.com/tiles/:table_name/infowindow
-
-Args:
-
-* infowindow - returns contents of infowindow from CartoDB.
-
-
-**MAP METADATA**
-
-[GET] subdomain.cartodb.com/tiles/:table_name/map_metadata
-
-Args:
-
-* infowindow - returns contents of infowindow from CartoDB.
-
-
-All GET requests are wrappable with JSONP using callback argument,
-including the UTFGrid map tile call.

 ## Maps API
 
-The CartoDB Maps API allows you to generate maps based on data hosted in your CartoDB account and style them using CartoCSS. The API generates a XYZ based URL to fetch Web Mercator projected tiles using web clients like Leaflet, Google Maps, OpenLayers.
+The CartoDB Maps API allows you to generate maps based on data hosted in your CartoDB account and you can apply custom SQL and CartoCSS to the data. The API generates a XYZ-based URL to fetch Web Mercator projected tiles using web clients such as [Leaflet](http://leafletjs.com), [Google Maps](https://developers.google.com/maps/), or [OpenLayers](http://openlayers.org/).
 
 You can create two types of maps with the Maps API:
 
 - **Anonymous maps**  
-  Maps that can be created using your CartoDB public data. Any client can change the read-only SQL and CartoCSS parameters that generate the map tiles. These maps can be created from a JavaScript application alone and no authenticated calls are needed. See [this CartoDB.js example]({{ '/cartodb-platform/cartodb-js.html' | prepend: site.baseurl }}).

+### Use with CartoDB.js
+Named maps can be used with CartoDB.js by specifying a named map in a layer source as follows. Named maps are treated almost the same as other layer source types in most other ways.
+
+```js
+var layerSource = {
+  user_name: '{your_user_name}', 
+  type: 'namedmap', 
+  named_map: { 
+    name: '{template_name}', 
+	layers: [{ 
+	  layer_name: "layer1", 
+      interactivity: "column1, column2, ..." 
+	}] 
+  } 
+}
+
+cartodb.createLayer('map_dom_id',layerSource)
+  .addTo(map_object);
+
+```
+
+[CartoDB.js](http://docs.cartodb.com/cartodb-platform/cartodb-js.html) has methods for accessing your named maps.
+
+1. [layer.setParams()](http://docs.cartodb.com/cartodb-platform/cartodb-js.html#layersetparamskey-value) allows you to change the template variables (in the placeholders object) via JavaScript 
+2. [layer.setAuthToken()](http://docs.cartodb.com/cartodb-platform/cartodb-js.html#layersetauthtokenauthtoken) allows you to set the auth tokens to create the layer
+
+##Static Maps API
+
+The Static Maps API can be initiated using both named and anonymous maps using the 'layergroupid' token. The API can be used to create static images of parts of maps and thumbnails for use in web design, graphic design, print, field work, and many other applications that require standard image formats.
+
+### Maps API endpoints
+
+Begin by instantiating either a named or anonymous map using the `layergroupid token` as demonstrated in the Maps API documentation above. The `layergroupsid token` calls to the map and allows for parameters in the definition to generate static images. 
+
+##### Definition
+
+<div class="code-title notitle code-request"></div>
+```bash
+GET /api/v1/map/static/center/:token/:z/:lat/:lng/:width/:height.:format
+```
+
+##### Params
+
+* **:token**: the layergroupid token from the map instantiation
+* **:z**: the zoom level of the map
+* **:lat**: the latitude for the center of the map
+* **:lng**: the longitude for the center of the map
+* **:width**: the width in pixels for the output image
+* **:height**: the height in pixels for the output image
+* **:format**: the format for the image, supported types: `png`, `jpg`
+  * **jpg** will have a default quality of 85.
+
+#### Bounding Box
+
+##### Definition
+
+<div class="code-title notitle code-request"></div>
+```bash
+GET /api/v1/map/static/bbox/:token/:bbox/:width/:height.:format`
+```
+
+##### Params
+
+* **:token**: the layergroupid token from the map instantiation
+* **:bbox**: the bounding box in WGS 84 (EPSG:4326), comma separated values for:
+    - LowerCorner longitude, in decimal degrees (aka most western)
+    - LowerCorner latitude, in decimal degrees (aka most southern)
+    - UpperCorner longitude, in decimal degrees (aka most eastern)
+    - UpperCorner latitude, in decimal degrees (aka most northern)
+* **:width**: the width in pixels for the output image
+* **:height**: the height in pixels for the output image
+* **:format**: the format for the image, supported types: `png`, `jpg`
+  * **jpg** will have a default quality of 85.
+
+Note: you can see this endpoint as:
+
+```bash
+GET /api/v1/map/static/bbox/:token/:west,:south,:east,:north/:width/:height.:format`
+```
+
+####Layers
+
+The Static Maps API allows for multiple layers of incorporation into the `MapConfig` to allow for maximum versatility in creating a static map. The examples below were used to generate the static image example in the next section, and appear in the specific order designated.
+
+**Basemaps**
+
+```javascript
+    {
+      "type": "http",
+      "options": {
+        "urlTemplate": "http://{s}.basemaps.cartocdn.com/dark_nolabels/{z}/{x}/{y}.png",
+        "subdomains": [
+          "a",
+          "b",
+          "c"
+        ]
+      }
+    },
+```
+
+By manipulating the `"urlTemplate"` custom basemaps can be used in generating static images. Supported map types for the Static Maps API are:
+
+          'http://{s}.basemaps.cartocdn.com/dark_all/{z}/{x}/{y}.png',
+          'http://{s}.basemaps.cartocdn.com/dark_nolabels/{z}/{x}/{y}.png',

+
+Additoinally, static images from Torque maps and other map layers can be used together to generate highly customizable and versatile static maps.
+
+
+####Caching
+
+It is important to note that generated images are cached from the live data referenced with the `layergroupid token` on the specified CartoDB account. This means that if the data changes, the cached image will also change. When linking dynamically, it is important to take into consideration the state of the data and longevity of the static image to avoid broken images or changes in how the image is displayed. To obtain a static snapshot of the map as it is today and preserve the image long-term regardless of changes in data, the image must be saved and stored locally.
+
+####Limits
+
+* While images can encompass an entirety of a map, the default limit for pixel range is 8192 x 8192.
+* Image resolution by default is set to 72 DPI
+* JPEG quality by default is 85% 
+* Timeout limits for generating static maps are the same across the CartoDB Editor and Platform. It is important to ensure timely processing of queries.
+
+
+### Examples
+
+After instantiating a map from a CartoDB account:
+
+<div class="code-title code-request with-result">REQUEST</div>
+```bash
+ GET /api/v1/map/static/center/4b615ff367e498e770e7d05e99181873:1420231989550.8699/14/40.71502926732618/-73.96039009094238/600/400.png

+# 1. Purpose
+
+This specification describes an extension for
+[MapConfig 1.3.0](https://github.com/CartoDB/Windshaft/blob/master/doc/MapConfig-1.3.0.md) version.
+
+
+# 2. Changes over specification
+
+This extension introduces a new layer type so it's possible to use a named map by its name as a layer.
+
+## 2.1 Named layers definition
+
+```javascript
+{
+    // REQUIRED
+    // string, `named` is the only supported value
+    type: "named",
+
+    // REQUIRED
+    // object, set `named` map layers configuration
+    options: {
+
+        // REQUIRED
+        // string, the name for the named map to use
+        name: "world_borders",
+
+        // OPTIONAL
+        // object, the replacement values for the named map's template placeholders
+        // See https://github.com/CartoDB/Windshaft-cartodb/blob/master/docs/Map-API.md#instantiate-1 for more details
+        config: {
+            "color": "#000"
+        },
+
+        // OPTIONAL
+        // string array, the authorized tokens in case the named map has auth method set to `token`
+        // See https://github.com/CartoDB/Windshaft-cartodb/blob/master/docs/Map-API.md#named-maps-1 for more details
+        auth_tokens: [
+            "token1",
+            "token2"
+        ]
+    }
+}
+```
+
+## 2.2 Limitations
+
+1. A Named Map will not allow to have `named` type layers inside their templates layergroup's layers definition.
+2. A `named` layer does not allow Named Maps form other accounts, it's only possible to use Named Maps from the very
+same user account.
