OpenLayers is developed and supported by a number of organizations around the world. We are also looking for sponsors to help support the community. If you are in a position where you want to support the development of OpenLayers, but do not have development resources to share, you may be interested in supporting through our sponsorship program.
As a framework, OpenLayers is intended to separate map tools from map data so that all the tools can operate on all the data sources. This separation breaks the proprietary silos that earlier GIS revolutions have taught civilization to avoid. The mapping revolution on the public Web should benefit from the experience of history.
Releases are made available on the downloads page. The code is also available in our Subversion repository. Using Subversion, you can keep up to the absolute bleeding edge of the code. If you wish to report a bug in the API, and you are able to use Subversion, please see if the bug has been fixed in Subversion first: OpenLayers is under rapid development, so things change quickly.
OpenLayers is still undergoing rapid development, so expect a lot to change in the next few weeks and months. We need your support! Please check the wiki for the very latest updates and documentation, and thank you for taking an interest.
