1.3.1

• Restored the ability to easily bypass all caches: X-TileStrata-CacheSkip: *

1.3.0

• Changed behavior of X-TileStrata-CacheSkip header. Now the value is expected to be in the format of [layer]/[file],[layer]/[file],.... This allows for granular control of what's being rebuilt when using tilestrata-dependency (0.4.0 required).
• Upgraded etag library.

1.2.0

• Added: "minZoom" layer option.
• Added: "maxZoom" layer option.

1.1.0

• Added: Introduced layer options. As of this release, there's a single "bbox" option that defines the extent of the layer. Any requests outside of this region will yield a 404 Not Found without touching any of the caches, providers, etc.

.layer('mylayer', {bbox: [
    -111.37390136718749,
    45.3297027614069,
    -111.11228942871094,
    45.47746617959318
]})

1.0.2

• Added X-TileStrata-CacheHit header to responses coming from a cache, not providers. Useful for debugging and plugins that monitor metrics (e.g. tilestrata-datadog)

1.0.1

• Bugfix: Fixed potential race condition. Response hooks that mutate headers could inadvertently affect the headers that end up being cached.

1.0.0

• Addition: Serve "robots.txt" so that search engines don't pick up tiles for image search.
• Addition: Added "qs" (query string) property to TileRequest.
• Change: Changed response hooks to be able to modify the response's headers, buffer, and status.
• Change: Plugins are now implemented via a single use() method instead of distinct registerProvider, registerCache, registerRequestHook, etc methods.

Breaking Changes

• Response hooks now must provide a reshook property instead of hook.
• Request hooks now must provide a reqhook property instead of hook.
• Response hooks now receive the response buffer, headers, and status bundled up in an object result. With this style, any of those properties can be overridden easily by changing them in the object.

Chaining Syntax: Almost all of the API has changed to follow a chaining syntax. The purpose of the change is to make layer configuration files much more readable and less verbose.

// old way
server.registerLayer(function(layer) {
   layer.setName('mylayer');
   layer.registerRoute('t.png', function(handler) {
       handler.registerCache(disk({...}));
       handler.registerProvider(mapnik({...}));
   });
   layer.registerRoute('[email protected]', function(handler) {
       handler.registerCache(disk({...}));
       handler.registerProvider(mapnik({...}));
   });
});

// new way
server.layer('mylayer')
   .route('t.png')
       .use(disk({...}))
       .use(mapnik({...}))
   .route('[email protected]')
       .use(disk({...}))
       .use(mapnik({...}));

0.7.1

• Log errors to console w/verbose debugging information.
• Added no-cache headers on requests that fail (500 status).

0.7.0

• Made listen() accept identical arguments to the http.Server listen() method. This makes it possible to set the hostname or bind to a socket instead.

strata.listen(8080, callback);
strata.listen(8080, '127.0.0.1', callback);
strata.listen(8080, '0.0.0.0', callback);

0.6.1

• Fixed default value for method on TileRequest objects. This fix is only precautionary – the problem being addressed shouldn't affect normal functioning of TileStrata.
