* Fixed a bug where `FeatureGroup``removeLayer` would unbind popups of removed layers even if the popups were not put by the group (affected [Leaflet.markercluster](https://github.com/danzel/Leaflet.markercluster) plugin) (by [@danzel](https://github.com/danzel)). [#861](https://github.com/Leaflet/Leaflet/pull/861)
Leaflet 0.4 contains several API improvements that allow simpler, jQuery-like syntax ([example](https://gist.github.com/3038879)) while being backwards compatible with the previous approach (so you can use both styles):
* Improved most methods and options to accept `LatLng`, `LatLngBounds`, `Point` and `Bounds` values in an array form (e.g. `map.panTo([lat, lng])` will be the same as `map.panTo(new L.LatLng(lat, lng))`)
* Added `addTo` method to all layer classes, e.g. `marker.addTo(map)` is equivalent to `map.addLayer(marker)`
* Added factory methods to most classes to be able to write code without `new` keyword, named the same as classes but starting with a lowercase letter, e.g. `L.map('map')` is the same as `new L.Map('map')`
* Improved zooming so that you don't get a blank map when you zoom in or out twice quickly (by [@danzel](https://github.com/danzel)). [#7](https://github.com/Leaflet/Leaflet/issues/7) [#729](https://github.com/Leaflet/Leaflet/pull/729)
* Drag-panning now works even when there are markers in the starting point (helps on maps with lots of markers). [#506](https://github.com/Leaflet/Leaflet/issues/506)
* Added `TileLayer``detectRetina` option (`false` by default) that makes tiles show in a higher resolution on iOS retina displays (by [@Mithgol](https://github.com/Mithgol)). [#586](https://github.com/Leaflet/Leaflet/pull/586)
GeoJSON API was improved to be simpler and more flexible ([example](https://gist.github.com/3062900)). The changes are not backwards-compatible, so be sure to update your old code.
* Added `style` option for styling vector layers, passed either as an object or as a function (to style vector layers according to GeoJSON properties).
* Added `filter` option to leave out features that don't correspond to a certain criteria (e.g. based on properties).
* Added `onEachFeature` option to execute certain code on each feature layer based on its properties (binding popups, etc).
* Changed `pointToLayer` function signature to provide `geojson` in addition to `latlng` when creating point features for more flexibility.
Icon API was improved to be more flexible, but one of the changes is backwards-incompatible: you now need to pass different icon properties (like `iconUrl`) inside an options object ([example](https://gist.github.com/3076084)).
* Converted `Icon` properties to options, changed constructor signature to `Icon(options)`.
* Made all `Icon` options except `iconUrl` optional (if not specified, they'll be chosen automatically or implemented using CSS). Anchor is centered by default (if size is specified), and otherwise can be set through CSS using negative margins.
* Improved `on` and `off` methods to also accept `(eventHash[, context])`, as well as multiple space-separated events (by [@Guiswa](https://github.com/Guiswa)). [#770](https://github.com/Leaflet/Leaflet/pull/770)
* Improved `off` to remove all listeners of the event if no function was specified (by [@Guiswa](https://github.com/Guiswa)). [#770](https://github.com/Leaflet/Leaflet/pull/770) [#691](https://github.com/Leaflet/Leaflet/issues/691)
* Added `TileLayer``setZIndex` method for controlling the order of tile layers (thanks to [@mattcurrie](https://github.com/mattcurrie)). [#837](https://github.com/Leaflet/Leaflet/pull/837)

* Added `TileLayer.WMS``setParams` method for setting WMS parameters at runtime (by [@greeninfo](https://github.com/greeninfo)). [#719](https://github.com/Leaflet/Leaflet/issues/719)
