Tiki and Cypht webmail interoperability started with Tiki20 (2019). Tiki had a webmail since the early days but it was buggy, lacked features and was not improving. Since it would require too much work (and some specific expertise about email protocols) to get it up to modern standards, it was determined a better strategy to integrate an existing project (despite tradeoffs like feature overlap, integration challenges, etc.). See also: Why did Tiki pick Cypht? Major work has been done since that time in Cypht, and in Tiki 21, 22, 23, 24, 25 and 26. Work is ongoing, so it's recommended to run the latest 26.x (and 27.x when released) from Git or Daily Build. Most enhancements and many fixes will not be backported as there are lots of changes. Please see this known issue. In June 2023, Cypht became a community project and Jason (the original author) is no longer the most active contributor. Jason is now more in an advisor mode. Cypht 1.4.0 was released in 2023-07. For the period of 2022-08-08 to 2023-08-08, there were 246 code commits, which represents an increase of 50 (25%) from previous 12 months.
