iOS Roadmap

Active

• Full Email Writing and Reading ExperienceImplement the full reading and writing email experience on mobile, including initial support for encrypted messages (OpenPGP and S/MIME with existing libraries). WYSIWYG is now wrapping up. The next piece is to connect the protocol and database to render email.
• JMAP Support - ExplorationAlready 80% finished. The intention is to implement the full protocol with all the basic infrastructure in place.

Planned

• JMAP Support - Complete ImplementationSupport the JMAP protocol as one of the first extra protocols we ship with by default outside of IMAP. Currently we are prioritizing IMAP and a first user release.
• DatabaseWe’re changing how we cache the email to be able to consume the UI faster, and moving the database work for after the first version is out to the users.

Shipped
