is there somewhere where we can see which reader/writer versions are supported in each delta lake release? i was hoping to find that here i saw the following log and wanted to verify that changing the version wouldn't break for existing spark applications before updating the min version requirements
Copy code
Please upgrade your Delta table to reader version 2 and writer version 5
 and change the column mapping mode to 'name' mapping. You can use the following command:

 ALTER TABLE <table_name> SET TBLPROPERTIES (
   'delta.columnMapping.mode' = 'name',
   'delta.minReaderVersion' = '2',
   'delta.minWriterVersion' = '5')
this doc has some more info but i'm still not seeing a link to which delta releases support which versions https://github.com/delta-io/delta/blob/master/PROTOCOL.md#writer-version-requirements
