The new API version allows you to upload files!
In v2, we've introduced the possibility to add attachments to your notes documents directly from your mobile phone or browser.
If you've been doing any configuration lately, you might have noticed a new input field appearing in the form editor. The field "File Upload" allows you to upload attachments directly to richtext fields in your documents. You can either specify a name for the richtext field, or leave it empty. If left empty, a new field will be created in your document called "_notes2mobileFileUpload".
In this first stage, we have only rolled out the new changes to the web client. The sharepoint and mobile versions will soon follow, we are still doing a bit of testing for these platforms!
