# Phileas 2.12.0

By [Jeff Zemerick](https://philterd.ai/authors/jeff-zemerick/) March 20, 2025 [Phileas](https://philterd.ai/categories/phileas/)

[Phileas](https://github.com/philterd/phileas) 2.12.0 has been released. This version of the popular open source redaction library brings:

- Filter priorities – Each filter can have its own priority that is used as a tie-breaker in cases where text is identified by two filters. For example, if you are using the phone number filter and an ID filter of 10 digit numbers, both filters may detect PII on the same text. In this case, the filter priority will be used to determine the ultimate labeling of the text as either a phone number or an ID number.
- Zip code validation – The zip code filter can now optionally attempt to validate zip codes. When enabled, if a zip code does not exist in the internal database, the zip code will not be redacted.
- Each filter can have a custom window size – The window size is roughly the number of words surrounding PII that is used to provide contextual information about the PII. Previously, each filter had to use the same window size. Now, each filter can have the window size set independently.

Look for a new version of [Philter](https://philterd.ai/philter/) soon in the AWS, Google Cloud, and Azure marketplaces soon that is built on Phileas 2.12.0!
