Hi, This is a suggestion, I think its useful to have a version with the siddhi extension name, The same extension can exists with different versions. Idea is if extension get change and new version arrives, no need to change existing queries.
Ex -: currency_1.0.siddhiext In the query should call the extension with the version. Then currency new extension arrives it may be 2.0. Will this be useful?
