I used fscrawler 2.7 to index my pdf files.
I've just noticed this on 'localhost:9200' " **minimum index compatibility version" : "6.0.0-betal**" (see below)
At what 'index compatibility version' will I need to re-index my files with the next version of fscrawler?
Do you have an estimate of when this is likely to be?
Thus year, next year . . . ?

The elasticsearch version you are is compatible with FSCrawler 2.7 SNAPSHOT.
