What’s new in Omeka 2.4
PHP 5.2 support dropped
Keeping up with adjusted support by our various third-party libraries, the lack of upstream support or updates, and its substantial age, Omeka 2.4 no longer supports PHP 5.2. PHP 5.3.2 is required at a minimum.
REST API changes
The item resource’s index now accepts tags, excludeTags,
hasImage, and range as GET parameters. These behave the same as
their preexisting counterparts on the regular items browse page.
