Thunderbird announced today the availability of their public roadmaps where they are making it easier for end-users to comprehend what they are currently working on for this mail client not only for the desktop builds but also their Android and iOS versions too.

Thunderbird has launched a new roadmap site to make it easier to digest the current and planned development activities for the Thunderbird desktop and mobile products. They intend to communicate roadmap changes here as well as keeping them up to date moving forward.

Some of the current desktop roadmap items for Thunderbird include finalizing its Microsoft Exchange protocol support to work across all versions of Exchange and Microsoft 365 -- including calendar and address book integration. Thunderbird is also working on its global "Panorama" database that will roll-out for testing. Plus improvements and extensions to Thunderbird's add-on APIs are also in the works.

Some of the planned items for Thunderbird on the desktop include enhancing the first time user experience, refreshing the calendar UI/UX, improving the Thunderbird settings interface, and encryption and security improvements.

For Thunderbird on Android and Apple iOS they are working to modernize the source code they obtained from K9, message view and message list improvements, and HTML signature support.

Thunderbird also road-mapped their services and infrastructure efforts with plans to complete the Send UI, active session tracking, multi-factor authentication support, improving the Pro add-on integration, and enhancing their proof-of-concept webmail view for Thunderbird Pro.
