Release 5.0.x
LemonTree 5.0.0
Release Date
10.08.2026
Info
We would like to inform you that with the LemonTree 5.0.0 release, we will stop supporting the 32-bit version of Enterprise Architect as well as Jet-based repositories (.eap, .eapx). This step has become necessary because the demand for these legacy technologies has declined significantly, while their continued maintenance ties up resources that we will invest in developing new and innovative features with greater value to our customers.
