Blog post slugs no longer carry the hex suffix that produced URLs like /dad-s-death--4fc1a3. The slug is set at publish time, capped at 80 characters, and stays put even if you edit the title later. If you need a fresh one, there's an explicit regenerate option. Any old URLs — including ones from previous regenerations — redirect permanently to the current canonical URL, so links you've already shared keep their value.
URL-seeded workflows no longer kick off automatically when you create them. The spreadsheet now shows an "Analyzed URL" column with a Run button on each row. Clicking it analyzes that URL and chains into idea generation. Rows you'd already analyzed before this change show as "Already analyzed" and go straight to idea generation.
