This update adds support for ItemsAdder v3.3.0 onwards.
To keep support for older versions are there now 2 zip files:
GridBlocks-<version>-old.zip
for ItemsAdder v3.2.5 and olderGridBlocks-<version>-new.zip
for ItemsAdder v3.3.0 and newer
For those who don't know already: ItemsAdder v3.3.0 changed its folder structures. The add-ons now go into a folder called contents
.
I've created a blog post to address these changes and how to migrate this:
