# Analyze

```{versionchanged} 3.0
`FilterCriteria` and `TrendCriteria` enums, plus the `Analyzer` wrapper and `BaseEnum.from_cli` helper, were replaced by {class}`~patcher.core.analyze.TitleFilter` and {class}`~patcher.core.analyze.TrendAnalysis`. Each former enum value is now a method on the respective class with its own signature.
```
