Leaflet GeoJSON API proposal

geojson.js

var geojson = L.geoJson(data, {

	// style for all vector layers (color, opacity, etc.), either function or object (optional)
	style: function (feature) {
		return feature.properties && feature.properties.style;
	},
	
	// function for creating layers for GeoJSON point features (optional)
	pointToLayer: function (feature, latlng) {
		return L.marker(latlng, {
			icon: myCustomIcon,
			title: feature.properties && feature.properties.name
		});
	},
	
	// function that gets called on every created feature layer (optional)
	onEachFeature: function (feature, layer) {
		var content = feature.properties && feature.properties.popupContent;
		if (content) {
			layer.bindPopup(content);
		}
	},
	
	// function that decides whether to show a feature or not (optional)
	filter: function (feature, layer) {
		return !(feature.properties && feature.properties.isHidden);
	}
	
}).addTo(map);

// add more GeoJSON data
geojson.addData(moreData);

map.fitBounds(geojson.getBounds());

my plugin mapsmarker.com offers the feature to add layer maps whose markers are loaded via GeoJSON. Since v0.4 this feature is broken.
According to the doc, the GeoJSON API has changed and is not backward-compatible. The shown example of the new API above
doesnt show, what exactly has to be changed in order to get old code working (in contrast to marker icon changes at https://gist.github.com/3076084) :-/

Here´s the code I used with leaflet <0.4 to load markers via GeoJSON. Can anyone please help, what has to be changed in order to work with 0.4?
And heres a link to a GeoJSON-File which gets loaded on layer maps: http://current.mapsmarker.com/wp-content/plugins/leaflet-maps-marker/leaflet-geojson.php?layer=14&callback=jsonp&full=yes
Many thanks!

var layers = {};
var geojson = new L.GeoJSON();
geojson.on("featureparse", function(e) {
if (typeof e.properties.text != 'undefined') e.layer.bindPopup(e.properties.text);
if (e.properties.icon != '') e.layer.options.icon = new L.Icon("/" + e.properties.icon);
if (e.properties.icon == '') e.layer.options.icon = new L.Icon("");
if (e.properties.text == '') e.layer.options.clickable = false;
layers[e.properties.layer] = e.properties.layername;
if (typeof markers[e.properties.layer] == 'undefined') markers[e.properties.layer] = [];
markers[e.properties.layer].push(e.layer);
});
var geojsonObj;

geojson.addGeoJSON(geojsonObj);
selectlayer.addLayer(mapcentermarker).addLayer(geojson);

i want to get feature properties and want to show in a div. Plz fine some solution.

var marker, popupContent, properties;
            marker = e.layer;
            properties = marker.feature.properties;
            popupContent = '<div class="popup"><h3><a href="/places/' + properties.id + '" target="marker">' + properties.name + '</a></h3><p class="popup-num">' + properties.description + ' Point of Interest No. ' + properties.id + '</p></div>';

            return marker.bindPopup(popupContent, {
                closeButton: false,
                minWidth: 300
            }).addTo(map);

all goes on 'layeradd' event, hope I'm not too late.

Thanks for sharing this code this really help to solve my problem.
