Basically it depends on what you're intending to do with the dissector.
If you're keeping it private, within a company you may want to just run the stable release version.
If you're going to submit the dissector back to the Wireshark project, then as per the Wireshark Development Submitting Patches wiki page, you should base your change off master (i.e. development). Bug fixes only can be backported to the stable versions, a new dissector will only be in the development version until that's released (see the LifeCycle wiki page for more notes about releases and backports) .
