Why struts version 2.3.4.1 and not 2.4?

Having an argument with my team members on the api difference and versioning I was stucked when it came to struts with four periods i.e. 2.3.4.1 (a bit weird) . I want to know why it has not picked version 2.4 but 2.3.4.1 ?? Where does the api difference cam in?

See this compatibility table for all struts API versions. There is a minor ABI break between 2.3.4 and 2.3.4.1 in the org.apache.struts2.util.TokenHelper class, but overall compatibility is still 99.9%.

Apache has guidelines on release numbering:

Minor Releases

Minor releases signify enhancements to a component that do not necessitate a major release. Developers may perform a minor release if the release is at least external-interface-compatible with the previous release.

Point Releases

A point release typically involves simple bug fixes or optimizations that do not introduce new features. Developers may perform a point release if the release is at least interface-compatible with the previous release.

So unless there are new API additions (which I have not looked at) you would not bump up the minor version number.

2.4 would be a "minor release".

2.3.4 (the last point release) only lists internal changes.

2.3.4.1 is not even a "point release", more like a patch, which seems to match the release notes, which say "Struts 2.3.4.1 includes important security fixes."
