 ### Installation remarks
 
+March 2026: From v1.2.6 on, seem to work with phenix/1.21 versions. v1.2.8 is compiled with phenix/1.21 version and needs to be tested to see whether it works.
+
 According to Elke de Zitter (as of Spring 2024) Xtrapol8 only runs with the phenix/1.19 version. 
 --> check for new releases...
