Am I understood correctly that add-on maintainers broke backward compatibility (changed sourcetype) starting with 3.8.1 version ? Or it was our bug?

Can we talk with them to understand the reason? Probably they will rollback this change if add-on not very popular :)

If we need to provide new sourcetype, probably good idea will be use some env var like BLUECOAT_NEW_FORMAT=false and will determine that we need assign old or new sourcetype for bluecoat. If will help us to prevent of breaking backward compatibility

that's a good question, 3.8.1 was released in September 2022 and I don't have access to older versions to check if that was changed on the TA side or there was a bug in SC4S

especially that bluecoat:proxysg:access:syslog is more consistent with the rest than bluecoat:proxysg:syslog

@mstopa-splunk you are right, it's impossible to check, because they deleted previous versions :)

Only 3.8.1 available on Splunkbase :)

@ikheifets-splunk please see how this has been done previously:

Note:[¶](https://splunk.github.io/splunk-connect-for-syslog/main/sources/vendor/Dell/sonicwall/#note)
The sourcetype has been changed in version 2.35.0 making it compliant with corresponding TA.

the practice seems to be updating the sourcetype and adding the note
