Thanks. None of these analyzers have changed in the last few months (certainly not the last few days or weeks).
Typically, this means something has changed with the files that are a part of your project. Something is included that wasn’t before (or an exclusion was removed).
You can see exactly what files are being analyzed if you turn on DEBUG logging and look at the scanner logs. This would also point to any languages you didn’t think were a part of the analysis.
It’s even better if you are able to compare previous logs from an analysis – although you probably don’t have DEBUG loggin turned on, you can still the languages and number of files indexed.
