The ICO has shared a detailed roadmap of their plans for new and updated guidance, and it’s a big list.
Some items are in development whilst a few have been issued, but it helps to know where their focus is, and you can see the whole list and more information at https://ico.org.uk/about-the-ico/what-we-do/our-plans-for-new-and-updated-guidance/.
I still hope that they get around to putting a date on their pages, so you can identify the latest information where there are two different versions of guidance.
