We are releasing the M8.2 patch to our latest M8 milestone to add a new openAttachment endpoint to the RPC interface.
Upgrading is recommended if you want to access the openAttachment interface. This change has an API addition.
You can read the documentation, and download the code from the release-M8 branch in our git repository. It is also available via Maven Central/JCenter and so you can upgrade your CorDapps to use it by switching to version 0.8.2 in your build files.
- RPC API: Added an openAttachment endpoint to the RPC interface and tests for the open, upload and exists attachment RPC interfaces.
