Version relates to analyzers and the like rather than to internals such as index format. I don't recall what exactly has changed between 4.0 and 4.3.1 but you're probably safe to change it and use LUCENE_43.
Take a look at the javadoc for StandardAnalyzer - that lists some versions and what changed with that version. -- Ian.
