-### Issues
-If you are upgrading from an older version (prior to v1.0.0-rc4) you may see an error similar to the below when starting OpenRefine:
-```
-Exception in thread "main" java.lang.Error: class org.apache.lucene.index.IndexFormatTooOldException:
-org.apache.lucene.index.IndexFormatTooOldException: Format version is not supported (resource 
-BufferedChecksumIndexInput(MMapIndexInput(path="C:\PATH\OpenRefine\cache\rdfExtension\export\luceneIndex
-\segments_1"))): -11 (needs to be between 1071082519 and 1071082519). 
-This version of Lucene only supports indexes created with 
-release 5.0 and later. 
-```
-This is due to an upgrade in the version of Lucene used. 
-To solve this you will need to remove the old Lucene index and restart OpenRefine, i.e., for the example above delete 
-```C:\PATH\OpenRefine\cache\rdfExtension\export\luceneIndex```.
-For Linux this will be under ```~/.local/share/openrefine/cache/rdfExtension/export/luceneIndex```
