# Release Notes for V1.9

> Release notes for Monolith platform V1.9: Custom Filter, Evaluate Anomaly Detection Models, Parallel Coordinates.

## New manipulators

* **Custom Filter**: The "Filter Numeric" and "Filter Category" steps were improved and unified in one step called "Custom filter". The UI is now more responsive to the operation type, and new positive and negative filters were created, including range filters. For more information, please refer to the [step documentation](/monolith-ai/1814203812/Custom+Filter). *The steps "Filter Numeric" and "Filter Category" will remain available until the next release, at which point they will be hidden from the manipulator pannel (but existing steps will still be visible and working).*
* **Evaluate Anomaly Detection Models** enables to quickly and automatically evaluate multiple Anomaly Detection models to (i) understand their maturity for usage in production, (ii) find the best model for a specific need (iii) identify the optimal threshold to use. The step will apply all selected models on validation data and return evaluation metrics (TP, FP, TN, FN, RoC) for all possible threshold values. See [step documentation](/monolith-ai/1814203807/Evaluate+Anomaly+Detection+Models) for more information.
* **Parallel Coordinates** step was added to the V1S platform. Main update on step is that it won't be possible to save the applied filtered data into a dataset that can be used downstream in the notebook. This also means that the step will be more responsive. See [step documentation](/monolith-ai/1814203840/Parallel+Coordinates) for more information.
