Does Paragraph publish new edited versions of a post to Arweave, or just the initial version? Would it be too expensive for every version to be published the Arweave?
We save new edited versions as well (only when you publish it again - not when you're just working on a draft). The Arweave tx on your post will update and point to the newest version upon publish. Arweave is extremely inexpensive so we try to save as much as possible
