Subject Re: Tomcat 4.1.29 versus Tomcat 5

If that is the case, it will be a loooong time until there will be a tomcat 
5.1. Since tomcat 5 went through so many public betas and originated from 
fairly stable tomcat 4.1 code - the quality tomcat 5 "stable" release is 
quite good. There weren't really any showstoppers requiring a quick minor 
release. (Kudos to Remy!)

There was a discussion about tomcat 5.1, but there aren't really any reasons 
to branch to 5.1 as compared to just enhancing the 5.0 branch.

5.0.17 should be tagged very soon from talk on the dev list.
