For Alcatel 4400 R1.x.x the last release was R1.5.3 ? This question is for the ancestors of the Alcatel-Lucent OmniPCX Enterprise. 
If I remember it right the R1.4 and R1.5 branches were developed in parallel. So technically for R1.x you have both last Release for R1.4 and last release for R1.5.But yes, 1.5.3 was last one.
