Joomla! 2.5 extension developer resources
I was compiling a quick-list with the Joomla! 1.6, 1.7 and 2.5 resources my developers and I used when we were converting ccInvoices and ccNewsletter to be Joomla! 1.6+ compatible, and thought the list might be useful to others.
The resources are actually easy to find, you just need to know where to look (and who to follow on twitter). But for those in a hurry, here is our own “Joomla! 2.5 Resources” document.
The section “Joomla! 2.5 extensions” applies mostly to extensions that are built from scratch for Joomla! 1.6+. the section “Joomla! 1.5+ extensions” applies to Joomla! 1.5 extensions that are being upgraded to also work in Joomla! 1.6 > 2.5.

Joomla! 2.5 Extensions
The best extension examples are probably in Joomla! itself. Just install the latest version and have a look at com_weblinks and other extensions.
