## 2.14.0
Released 2015-09-30
Summary: this starts using Windshaft as library (aka version 1.0.0), it no longer extends old Windshaft server.
Announcements:
- Upgrades windshaft to [1.0.0](https://github.com/CartoDB/Windshaft/releases/tag/1.0.0)
New features:
- Named tiles: /api/v1/map/named/:name/:layer/:z/:x/:y.:format
Ported from Windshaft pre-library:
- Almost all acceptance tests, some unit and some integration tests
- Stats + profiler
New features:
- Named maps MapConfig provider
- Base controller with: req2params, send response/error mechanisms
- Authentication/Authorization moves to its own API so it can be reused
- Surrogate-Key headers for named maps and affected tables
Improvements:
- No more fake requests to emulate map config instantiations
- As named maps previews are using named map MapConfigProvider it doesn't need to load the MapConfig
- Controllers using Windshaft's backends to request resources through MapConfig providers
- Express 4.x, as Windshaft no longer provides an HTTP server, here we start using latest major version of Express.
- assert.response implemented using request
- All tests validate there are no unexpected keys in Redis and keys requested to be deleted after a test are present
- Test suite in Makefile generated with `find`
- Image comparison with `mapnik.Image.compare`
- Doesn't emit Named map update event on unmodified templates
TODO:
- Named map provider checks on every request if named map has changed to reload it (actually reset it so MapConfig has to be regenerated). See https://github.com/CartoDB/Windshaft-cartodb/commit/f553efa69e83fdf296154ab1b7b49aa08957c04e. This is done this way because when running the Service in a cluster there is no communication between different instances so when a named map gets updated in one of the them the rest is not aware/notified of the change. In the future there should be a mechanism to synch this changes between instance:
* endpoint
* redis pub/sub
* backdoor

## 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
