+- update to version 2.5.7:
+ - Enhancements:
+  - New example notebook explaining how to use projects, artifacts, and alerts.
+  - New filter for lists of substrings on all RecordList objects.
+  - New API library for Trackers to support recently-introduced endpoints that enable
+  - pagination. Ensured pagination for `analyzer.Tracker` objects works correctly with new
+  - API library. It is now possible to download hundreds of thousands of tracker search
+  - results by accessing the `observations_by_ip` or `observations_by_hostname` property of
+  - a Tracker.
+ - Bug Fixes:
+  - Add missing docstring for filter_date* functions on RecordList objects.
+  - Resolved issue that blocked filtering of project alerts with filter* functions.
+  - Fixed dataframe column names on vulnerability objects to match properties.
