The OpenLayers dev team is proud to announce the 4th release candidate of OpenLayers 2.12! This RC fixes the following bugs:

• The Layer.getServerZoom method introduced a regression that may trigger when using XYZ layers as overlays.
• The calculation of maxResolution based on tileSize is incorrect for single tile layers.
• The GPX format does transform geometries when necessary, but does serialize the transformed coords.
• The BBOX strategy may fetch data while the layer is out of range.

See   https://github.com/openlayers/openlayers/issues?milestone=5&state=closed for details.

We invite you to help us test the 2.12 release candidate! To test 2.12 in your applications, include the following tag in your OpenLayers-powered page:
