This is a new release 3.2 of the Joomla plugin Google Maps that restores the kml proxy feature in a secure way that was removed in the previous version because of security risks. It protects against automation because the plugin checks if the url/content is authorised and used in the article that the visitor of the website requested. The kml proxy is by default switched off in the configuration of the plugin and makes the proxy for kml files method not available. 
Also it solves some problems for responsive templates.
It can be downloaded at Joomlacode. The file with J15 in the name is for Joomla 1.5 and the file J25_J3x in the name is for Joomla 2.5/3.x.
The new version has the following new features:
  • Added language possibilities for GeoXML and gotoaddress form
  • Open infowindow in KML by parameter (GeoXML)
Solves the following errors:
  • New authorisation for Twitter
  • Security risks in kml proxy
  • Problem of standalone Joomla application for kml proxy, twitter and css settings
  • Problem with clouds
  • Standard use Google Maps API version stable instead of development
  • Support for language with multiple dialects (Portugese/Chinese)
  • Problem with zoom and center in lightbox
  • Solves problems with responsive templates
The update will automatically update in Joomla 2.5/3.x.
If you still use Joomla 1.5, you must update it yourself.
If you use the plugin with version lower that 3.0 then please, read this article
Language support for English, French, Italian, Spanish and Swedish for all the parameters. Please send language files thru my website so I can add them to the plugin.
Have fun with the plugin.
Kind regards Mike
