Quick question - did you encounter any configuration changes to the promtail config that would need to be considered for the version bump?

We are running this role with an overwritten version right now in our staging environment.
So far we haven't any issues.

The only changes in the configuration I could find are these two point which are documented in the changelogs. These only ad functionality and don't break anything:

• 2060 introduces the Replace stage, which lets you find and replace or remove text inside a log line. Combined with 2422 and 2480, you can now find and replace sensitive data in a log line like a password or email address and replace it with ****, or hash the value to prevent readability, while still being able to trace the value through your logs. Last on the list of pipeline additions,
• 2496 adds a Drop pipeline stage, which lets you drop log lines based on several criteria options including regex matching content, line length, or the age of the log line. The last two are useful to prevent sending to Loki logs that you know would be rejected based on configured limits in the Loki server.
