I reviewed the upcoming changes to SNFLK (release bundle 2022_01) to check whether there are any major changes.
Here are things I think could theoretically affect userland SQL in transformations and workspaces:
- COPY INTO to external location difference in regex matching (internal usage by Keboola Connection is not affected)
- Changes to JS stored procedures error handling
- New behavior of COMMIT of transactions that timed out or has been aborted
You can see all pending changes in behavior change log.
