What started in version 1.5 with NewsBlur, Inoreader, AOL Reader and The Old Reader and more importantly a more streamlined internal architecture for adding new services, now bears its fruits with version 1.6 and even more services. Newly supported in 1.6 are the selfhosted Tiny Tiny RSS and the read-it-later services Readability, Instapaper and Pocket.
