+- update to version 2.5.4:
+ - Enhancements:
+  - Removed strict checking on tracker type to permit querying by arbitrary tracker types. Updated list
+    of common trackers. Added searchType param to docs to reflect API's capability of returning either
+    hostnames or addresses.
+  - New methods to search trackers in the `analyzer` module, including `tracker_references` property on
+    `Hostname` and `IPAddress` objects to find other sites referencing the focus host in their tracker
+    values.
+  - New `analyzer.Tracker` top-level entity with `observations_by_ip` and `observations_by_hostname`
+    properties to find other hosts with the same tracker type and value. 
+  - New `filter_fn` method on all RecordList objects enables filtering a list by an arbitrary function.
+    Helps reduce code duplication and enables more advanced filtering. 
+  - Monitoring API endpoint support in the core library, and new `alerts` property on 
+    project artifacts to easily retrieve the list of new alerts for an artifact in a project.
+    Handles pagination automatically and returns results in new analyzer objects to enable
+    standard filtering and data representation (i.e. `as_dict` and `as_df`).
+  - Small change to the `get_object` method to tolerate passing it objects that are already
+    `analyzer.Hostname` or `analyzer.IPAddress` objects.
+  - New `is_ip` and `is_hostname` methods on both `Hostname` and `IPAddress` objects to simplify
+    code that operates against a list of hosts that may include objects of both types.
+  - New methods on Tracker search results and Hostpair results to exclude records with hostnames, 
+    domains or tlds in a given list. This helps refine results to focus on "foreign" sites and enables direct
+    application of proven phishing site detection use cases.
+ - Bug Fixes:
+  - Fixed incorrect constant reference in trackers API (by removing strict checking on
+    tracker type).
+  - Fixed broken `age` property on Articles that was also causing `as_df` and `as_dict` to fail.
+    Likely caused by missing time zone info in dates returned from the API.
