A new release of Leaflet.Deflate is now available. Leaflet.Deflate 2.1 introduces a new option, greedyCollapse, to specify when features will collapse.
With greedyCollapse set to true, a feature collapses when either its width or height falls below the specified threshold. This is the default, and it matches the behaviour from previous versions. Set greedyCollapse to false, and features will collapse only of both width and height fall below the specified threshold. This behaviour comes in handy when you have many “long” features on your map.
My thanks to Simonas Gildutis for contributing the new feature.
