Leaflet-IIIF v2.0.0 presents a slightly backwards incompatible enhancement that many users will find useful.

Enhancements

#68 Updates examples to use Leaflet v1.3.1 #68 Adds support for Leaflet's minZoom and minNativeZoom options calculating automatically.

Major Changes

The changes added #68 will automatically recalculate zooms for a given map based on the map size and the preferred tilesize coming from the IIIF server. Many users will find this useful, especially with IIIF servers that are preferring to deliver large tiles (1024).

Updates jQuery version. Not a requirement for Leaflet-IIIF to work, but gets a security patch.

Added option setMaxBounds #63

Thanks @dhdemerson

Fixes a bug where an explicit tileSize was not being honored. Also sets a default tileSize if not specified or in an info.json response.

Update package.json to only include relevant files

Adds support for leaflet v1.0.0
